Essential Ingredients for Your Ultimate Sweet and Sour Tofu

Creating this spectacular sweet and sour tofu requires a handful of accessible and fresh ingredients, each carefully chosen to build the layers of flavor and texture that make this dish truly special. Paying attention to the quality of your ingredients and understanding their role is key to a successful and delicious outcome. Below is a detailed look at what you’ll need, along with some insights into why these ingredients are crucial and potential substitutions. Remember to always scroll down to the full recipe card for precise measurements and quantities!

For the Crispy Tofu and Flavorful Vegetables

  • Extra-Firm Tofu: The cornerstone of this plant-based dish. Extra-firm tofu is highly recommended due to its naturally low water content, which allows it to get incredibly crispy when cooked and holds its shape beautifully under high heat. If extra-firm isn’t readily available, firm tofu can be used, but ensure you press it even more thoroughly to remove maximum excess moisture. Pressing tofu is a crucial preliminary step for achieving that desirable crispy texture, preventing it from becoming bland and mushy.
  • Cornstarch (for tofu coating): This is our indispensable secret weapon for achieving that coveted, irresistibly crispy exterior on the tofu. Coating the uniformly cut tofu cubes in cornstarch before frying creates a light, golden-brown, and crunchy crust that locks in moisture, enhances the flavor absorption, and adds a delightful textural contrast to the soft interior.
  • Oil: Using a high smoke point cooking oil is absolutely essential for pan-frying the tofu to golden perfection and stir-frying the vegetables without burning or imparting off-flavors. Avocado oil is a fantastic choice due to its neutral flavor and very high smoke point. Other suitable neutral cooking oils include canola oil, grapeseed oil, or sunflower oil.
  • Garlic: Freshly minced garlic is always preferred for its pungent aroma and robust, zesty flavor, which forms a foundational aromatic base for the stir-fry. It adds depth and warmth. While store-bought pre-minced garlic works in a pinch for convenience, for the freshest and most impactful taste, we highly recommend fresh garlic cloves.
  • Bell Peppers (Green, Red, and Yellow): To create a visually stunning and nutritionally rich dish, a colorful medley of green, red, and yellow bell peppers is highly recommended. Each color offers a slightly different sweetness level and contributes to the overall vibrant aesthetic and abundant health benefits of the meal. They add a fresh, crisp crunch and a subtle sweetness that complements the sauce beautifully.
  • Pineapple Chunks: This ingredient is a non-negotiable for an authentic and vibrant sweet and sour experience, in our opinion! Pineapple adds a burst of tropical sweetness and a delightful tangy acidity that perfectly complements and balances the savory elements of the dish. While you can technically omit it if you truly dislike pineapple, its contribution to the classic flavor profile and overall appeal is unmatched. You have the flexibility to use either fresh pineapple, cut into bite-sized chunks, or well-drained canned pineapple chunks.
  • Onion (Red and Green): We strategically utilize both red onion and green onion in this recipe for layered flavor and visual appeal. Diced red onion provides a sharper, more pungent base flavor when sautéed, adding depth to the vegetable medley. Sliced green onions (scallions) are typically added towards the end of cooking or as a garnish for a milder, fresher onion bite and a final pop of bright color.

For the Irresistible Homemade Sweet and Sour Sauce

  • Ketchup: This readily available pantry staple gives the sweet and sour sauce its iconic vibrant red color and contributes significantly to the characteristic sweet, tangy, and subtly savory flavor profile. It forms a robust base for the sauce.
  • Granulated Sugar: Essential for achieving the desired level of sweetness, granulated sugar perfectly balances the sour notes from the vinegar and the natural tang of the pineapple. You can easily adjust the amount slightly to suit your personal preference for sweetness.
  • White Vinegar: This is the crucial ingredient responsible for the “sour” component of the sauce, providing a sharp, clean, and bright tang that is characteristic of classic sweet and sour dishes. Apple cider vinegar can be an excellent substitute if you prefer a slightly fruitier, milder acidity profile.
  • Soy Sauce: Adds a vital layer of umami, salinity, and savory depth to the sauce, rounding out the flavor profile and enhancing the overall complexity. For those requiring a gluten-free option, tamari or coconut aminos are excellent, flavor-rich alternatives that perform just as well.
  • Cornstarch and Water (for slurry): This dynamic duo is absolutely critical for thickening the sauce to that perfect, luscious, and glossy consistency. Mixed together vigorously in a separate bowl before being added to the hot pan, they create a smooth slurry that prevents clumps and ensures a beautifully smooth, thick, and shiny finish that adheres wonderfully to the crispy tofu and vibrant vegetables.

Mastering Sweet and Sour Tofu: A Step-by-Step Guide

Creating this delicious sweet and sour tofu is a straightforward process, even for beginner cooks. Each step is designed to build layers of flavor and texture, culminating in a perfectly balanced and incredibly tasty meal. Follow these detailed instructions to achieve a restaurant-quality dish right in your own kitchen. For the full, precise recipe details, including exact measurements and nutritional information, make sure to check the dedicated recipe card at the very bottom of this article.

  1. Prepare and Crisp the Tofu: Begin by thoroughly pressing your extra-firm tofu to remove as much excess water as possible – this is a critical step for achieving a truly crispy texture. Once pressed, cut the tofu into uniform, bite-sized cubes. In a shallow bowl or a large Ziploc bag, toss the cubed tofu with ¼ cup of cornstarch until each piece is lightly and evenly coated. This cornstarch coating is the key to developing that desirable golden, crunchy exterior during frying.
  2. Pan-Fry the Tofu to Perfection: Heat a large skillet or wok over medium-high heat. Add 3 tablespoons of cooking oil, allowing it to shimmer and become hot but not smoking. Carefully add the cornstarch-coated tofu cubes to the hot skillet in a single layer, ensuring not to overcrowd the pan. Cook the tofu for about 5-7 minutes per side, or until it develops a beautiful golden-brown and irresistibly crispy crust. Resist the urge to move the tofu too much initially, as this allows a proper crust to form. Flip and cook on all sides for maximum crispiness, or just two sides if you’re short on time. Once the tofu is beautifully crispy, remove it from the skillet and set it aside in a warm place to maintain its temperature and texture.

  1. Sauté the Flavorful Fresh Ingredients: Using the same skillet (add a touch more oil if needed to prevent sticking), add the minced garlic, diced bell peppers (green, red, and yellow), and diced red onion. Sauté these vibrant vegetables for approximately 7-10 minutes over medium heat, stirring occasionally, until they become tender-crisp and slightly softened but still retain a pleasant bite and their vibrant color. Add the pineapple chunks during the last few minutes of cooking to warm them through and allow their sweetness to meld with the other ingredients.

  1. Prepare the Sweet and Sour Sauce: While the vegetables are gently sautéing, prepare your irresistible homemade sweet and sour sauce. In a separate small bowl or measuring cup, vigorously whisk together the ½ cup ketchup, ⅓ cup granulated sugar, ¼ cup white vinegar, ¼ cup soy sauce, 3 tablespoons cornstarch (for the sauce), and 3 tablespoons water until thoroughly combined and perfectly smooth. This mixture creates a slurry that will thicken the sauce beautifully without any unsightly clumps. Once the vegetables are tender, pour this complete sauce mixture directly into the skillet with the sautéed ingredients.
  2. Thicken and Combine the Flavors: Bring the sauce mixture to a gentle simmer over medium heat, stirring continuously to prevent scorching. Allow it to cook for about 2-3 minutes, or until the sauce visibly thickens to your desired luscious consistency – it should be glossy and able to coat the back of a spoon. Taste the sauce at this point and adjust for sweetness or tanginess if desired.
  3. Toss to Coat and Serve: Carefully add the reserved crispy tofu back into the skillet with the perfectly sautéed vegetables and the freshly thickened sweet and sour sauce. Gently toss everything together using a spatula or tongs, ensuring all the crispy tofu pieces and vibrant vegetables are thoroughly coated in the luscious, glossy sauce. Garnish generously with the sliced green onions for a final touch of freshness and color. Remove from heat immediately to prevent overcooking the tofu and serve hot, ideally over a bed of fluffy white, jasmine, or sticky rice. Enjoy your homemade sweet and sour tofu masterpiece!

Expert Tips for the Best Sweet and Sour Tofu Every Time

While this sweet and sour tofu recipe is designed to be straightforward, a few key tips and tricks can elevate your dish from good to absolutely phenomenal. Pay close attention to these details, and you’ll be enjoying perfectly crispy tofu and a perfectly balanced, flavorful sauce with every single bite.

  • Master the Cornstarch Slurry for Sauce Perfection: This step is arguably the most crucial for achieving a smooth, glossy, and beautifully thick sauce. Do NOT add cornstarch and water separately to the hot sauce! Always whisk them together thoroughly in a separate small bowl first to create a smooth, lump-free slurry before gradually incorporating it into the other sauce ingredients in the pan. This prevents clumping and ensures your sauce achieves that signature silky texture and delightful sheen that will cling perfectly to your crispy tofu and vibrant veggies, enhancing every mouthful.
  • Prioritize Crispy Tofu: There’s nothing worse than mushy, soggy tofu in a stir-fry, and frankly, no one is a fan! To avoid this common pitfall, always start with extra-firm tofu and press it well to remove as much excess moisture as possible. Coating the tofu liberally and evenly in cornstarch before frying is non-negotiable for that golden crust. Ensure your pan is adequately hot and your cooking oil is shimmering before adding the tofu. Cook until it’s beautifully golden and crispy on at least two sides, but ideally, take the extra time to flip and cook until all sides are uniformly crisp. This textural contrast is what makes the dish truly enjoyable and satisfying.
  • Ensure Uniformity in Vegetable Size: For a harmonious texture throughout the dish and to ensure even cooking, aim to chop your bell peppers, red onion, and pineapple pieces into roughly the same size, ideally bite-sized cubes. This attention to detail ensures that every ingredient cooks uniformly, fits perfectly on your fork, and creates the ideal balanced bite with each mouthful, preventing some vegetables from being undercooked or overcooked.
  • Do Not Overcrowd the Pan: When cooking the tofu, it’s incredibly tempting to add all the pieces at once, especially if you have a smaller skillet. However, overcrowding the pan drastically lowers its temperature, causing the tofu to steam rather than fry. This results in soft, less crispy tofu. Cook the tofu in batches if necessary, ensuring each piece has enough space to crisp up properly and achieve that desired golden-brown exterior. Patience here pays off!
  • Adjust Sweetness and Tanginess to Your Taste: The beauty of a homemade sauce is its incredible adaptability. Feel free to taste the sauce after it has thickened and adjust the amount of sugar or white vinegar to suit your personal preference. Love it a touch sweeter? Add a small amount more sugar. Crave more tang and zest? A splash more vinegar will do the trick. Always adjust gradually, tasting as you go, until you hit your perfect balance.
  • Consider Using a Wok for Authentic Stir-Frying: While a large skillet works perfectly well for this recipe, a wok can truly enhance your stir-fry experience. Its unique, sloped shape allows for quick, even cooking at high temperatures, which is ideal for rapidly sautéing vegetables and crisping tofu. If you have one, this is the perfect opportunity to utilize it for an even more authentic and efficient cooking process.

Creative Substitutions & Delicious Recipe Variations to Customize Your Meal

One of the absolute best aspects of home cooking is the boundless freedom to customize dishes to perfectly fit your dietary needs, pantry staples, or unique flavor preferences. This sweet and sour tofu recipe is incredibly versatile, making it easy to adapt and truly make your own. Here are some simple yet effective ways to transform this classic dish into something uniquely yours, ensuring everyone at your table finds something to love:

  • Making it Gluten-Free: The core ingredients in this recipe are largely naturally gluten-free, with the key exception being traditional soy sauce. To ensure your delicious dish is entirely gluten-free, simply replace the standard soy sauce with a certified gluten-free soy sauce, tamari, or coconut aminos. Tamari is a particularly excellent choice as it closely mimics the flavor of soy sauce without the gluten. Always make it a diligent habit to check the labels of all other packaged ingredients (such as ketchup or cornstarch) to confirm they are also certified free from gluten contaminants.
  • Pineapple Perfection – Fresh vs. Canned: You have wonderful flexibility when it comes to the pineapple in this recipe. You can use either well-drained canned pineapple chunks or freshly cut pineapple. While fresh pineapple often brings a brighter, more intense tropical flavor and a firmer texture that many adore, it does require a bit more prep work. Canned pineapple, on the other hand, is wonderfully convenient, consistently sweet, and still delivers that essential sweet and tangy burst that makes the dish shine. Both options will yield incredibly delicious results, so choose what works best for your schedule and taste preference.
  • Tailor Your Bell Peppers: Not everyone loves all bell pepper colors, and that’s perfectly fine! Some individuals might find green bell peppers slightly more bitter, for instance. If you have a strong preference or an aversion to a particular color of bell pepper, feel free to omit it. Simply replace it with an equal amount of your favorite colored pepper (red, yellow, or orange are generally sweeter), or increase the quantity of the peppers you do enjoy. The goal is to maintain that vibrant medley and a good vegetable-to-tofu ratio for visual appeal and balanced nutrition.
  • Incorporate More Vegetables: This sweet and sour tofu recipe serves as a fantastic and flexible base for incorporating a wider variety of additional vegetables. Consider boosting the nutritional content and textural variety by adding broccoli florets, tender snap peas, thinly sliced carrots (julienned or cut into thin rounds), crisp water chestnuts, sliced zucchini, or even earthy mushrooms. Remember to add harder vegetables like carrots and broccoli earlier in the sautéing process, and softer ones like zucchini or mushrooms later, to ensure everything cooks evenly to a tender-crisp perfection.
  • Amp Up the Spice: If you enjoy a delightful hint of heat or a fiery kick in your meals, don’t hesitate to customize the spice level. A pinch of red pepper flakes tossed in with the vegetables during sautéing, or a dash of your favorite sriracha or chili garlic sauce mixed directly into the sweet and sour sauce, can provide a wonderfully satisfying zing. Start with a small amount and add more to taste.
  • Experiment with Alternative Proteins: While crispy tofu is the undisputed star here, this versatile sweet and sour sauce and vibrant vegetable medley can easily accommodate other plant-based proteins. You could successfully substitute the tofu with marinated tempeh cubes, hearty chickpeas, or even store-bought plant-based chicken alternatives for a different textural and flavor twist. Remember to adjust cooking times accordingly for your chosen protein.

Perfect Pairings: What to Serve with Sweet and Sour Tofu

This sweet and sour tofu is a remarkably flavorful and satisfying meal all on its own, but pairing it with the right accompaniments can truly elevate your dining experience even further. These thoughtfully chosen side dishes and beverages are designed to complement the vibrant flavors and textures of the tofu and sauce, creating a complete and harmonious meal that’s perfect for any occasion.

  • Classic Rice Varieties: The ultimate and arguably indispensable companion for saucy Asian-inspired dishes, rice is an absolute must-have with sweet and sour tofu. Its neutral flavor and wonderfully absorbent texture make it perfect for soaking up every last drop of that delicious, glossy sweet and sour sauce, ensuring no flavor goes to waste.
    • Fluffy White Rice: Simple, light, and always a reliable choice, fluffy white rice provides a clean canvas that allows the rich flavors of the tofu and sauce to truly shine.
    • Fragrant Jasmine Rice: Known for its delicate aroma and slightly sticky texture, jasmine rice adds an aromatic and slightly richer dimension to the meal, making each bite more enjoyable.
    • Chewy Sticky Rice: With its delightful chewiness, sticky rice is fantastic for scooping up the saucy tofu and vegetables, offering a satisfying textural contrast.
    • Healthy Brown Rice or Quinoa: For a more wholesome, fiber-rich, and nutty alternative, brown rice or quinoa can provide a hearty and nutritious base, adding a different depth of flavor and texture.
  • Refreshing Beverages: To beautifully complement the vibrant and often tropical flavors of the sweet and sour tofu and pineapple, consider pairing your meal with a refreshing drink that cleanses the palate and enhances the experience.
    • Fruity Punches (Alcoholic & Non-Alcoholic): A tropical-inspired punch, such as a Pineapple Orange Rum Punch (perfect for adult gatherings), would perfectly echo and enhance the delicious pineapple notes already present in the dish. For a non-alcoholic, family-friendly option that’s just as delicious and bright, a Refreshing Summer Punch is an excellent choice.
    • Iced Green Tea: A crisp, unsweetened iced green tea can provide a wonderfully refreshing and slightly earthy counterpoint to the richness and sweetness of the sauce, cleansing your palate between bites.
    • Sparkling Water with Citrus: A simple sparkling water infused with a generous squeeze of fresh lime, lemon, or orange offers a light, effervescent, and naturally palate-cleansing option that highlights the dish’s vibrant flavors.
  • Lightly Steamed or Sautéed Greens: To round out the meal with extra freshness, essential vitamins, and a gentle earthy balance, a simple side of lightly steamed or quickly sautéed greens can be a wonderful addition. Think tender bok choy, crisp broccoli florets, or even wilted spinach, seasoned simply with a touch of sesame oil and a drizzle of light soy sauce.
  • Appetizers for a Complete Feast: If you’re hosting a larger gathering, creating a “take-out at home” experience, or simply desire a more elaborate meal, serving your sweet and sour tofu alongside some complementary appetizers can be a delightful addition. Consider homemade or store-bought vegetarian spring rolls, crispy vegetable egg rolls, or delicate steamed dumplings to complete your feast.

Storing & Reheating Your Sweet and Sour Tofu Leftovers

One of the many delightful benefits of this sweet and sour tofu recipe is that it often yields delicious leftovers, perfect for a quick and flavorful lunch or dinner the next day. Proper storage and reheating techniques are absolutely key to maintaining its fantastic flavor and, as much as possible, its desirable texture. Here’s how to best handle your leftovers to ensure they taste almost as good as freshly made:

  • To Store: Once your sweet and sour tofu and vegetables have cooled completely to room temperature (to prevent condensation and bacterial growth), transfer them promptly into an airtight container. Store this container in the refrigerator, where your leftovers will remain fresh, safe, and flavorful for approximately 2-3 days. While the tofu might lose a slight bit of its initial crispiness over time due to moisture, the flavors will meld beautifully, often tasting even richer and more complex the next day.
  • To Reheat: While reheating in a microwave is certainly the quickest and most convenient option, especially when you’re short on time, we highly recommend using your stovetop for the absolute best results. Tofu, in particular, benefits significantly from stovetop reheating, as this method helps to restore some of its texture and prevents it from becoming rubbery, overly soft, or dried out.
    • Stovetop Method (Recommended for Best Texture): Place your leftover sweet and sour tofu and veggies in a non-stick pan or skillet over medium-low heat. Add a tiny splash of water or vegetable broth to the pan; this helps to prevent sticking and rehydrates the sauce, bringing it back to life. Stir gently and cook for several minutes until the tofu and vegetables are thoroughly warmed through. This method is excellent for helping to crisp up the tofu slightly again and keeps the vegetables from becoming overly soft or mushy.
    • Microwave Method (Quick and Convenient Option): If you’re truly pressed for time, place the tofu and veggies in a microwave-safe dish. Cover loosely with a lid or microwave-safe plastic wrap (leaving a small vent) to trap steam and prevent drying. Heat in 30-second to 1-minute intervals, stirring gently in between, until heated evenly through. Be mindful that the tofu might not regain its crispness using this method, but the flavors will still be delicious.

Frequently Asked Questions (FAQ) About Sweet and Sour Tofu

Here are answers to some common questions you might have about making, customizing, and enjoying this delicious sweet and sour tofu recipe:

  • Do I really need to press the tofu? Yes, absolutely! Pressing extra-firm tofu is a crucial preliminary step for this recipe. It physically removes excess water from the tofu block, which is vital for preventing the tofu from steaming instead of frying. This allows the tofu to absorb flavors better, achieve that wonderfully crispy exterior we’re aiming for, and ensures it doesn’t become soggy. If you skip this step, your tofu will likely be soft, lack texture, and won’t get that desirable golden crust.
  • Can I bake or air fry the tofu instead of pan-frying? Yes, you certainly can! For a healthier, lower-oil option, baking or air frying the tofu are fantastic alternatives that still yield a deliciously crispy result.
    • To Bake: After pressing, toss the cornstarch-coated tofu cubes with just 1-2 tablespoons of oil. Spread them in a single layer on a parchment-lined baking sheet. Bake at 400°F (200°C) for approximately 25-30 minutes, making sure to flip the tofu halfway through, until it’s beautifully golden brown and crispy.
    • To Air Fry: Toss the cornstarch-coated tofu with just 1 tablespoon of oil. Arrange the tofu in a single layer in your air fryer basket. Air fry at 375°F (190°C) for 15-20 minutes, shaking the basket vigorously halfway through to ensure even crisping.
  • Is this recipe vegan? Yes, this sweet and sour tofu recipe is inherently and completely vegan! Tofu is a widely recognized plant-based protein, and all the other ingredients used in this recipe—including the vegetables and all sauce components—are also vegan-friendly. It’s a fantastic and flavorful choice for anyone following a plant-based diet or looking to incorporate more vegan meals into their routine.
  • Can I prepare the sweet and sour sauce in advance? Absolutely! The homemade sweet and sour sauce is an excellent component to prepare ahead of time. You can whisk all the sauce ingredients together a day or two in advance and store the mixture in an airtight container in the refrigerator. This can significantly help save valuable time on busy cooking days. Just remember to give it a good, vigorous whisk or shake before adding it to the pan, as the cornstarch tends to settle at the bottom.
  • What if my sauce is too thin or too thick? How can I fix it?
    • If the Sauce is Too Thin: If your sauce isn’t thickening as desired, it likely needs a bit more cornstarch. In a separate small bowl, mix 1 teaspoon of cornstarch with 1 tablespoon of cold water to create a smooth slurry. Gradually whisk this slurry into your simmering sauce, stirring constantly, until it reaches your desired thickness.
    • If the Sauce is Too Thick: If the sauce becomes overly thick or gloopy, simply whisk in a tablespoon or two of water or vegetable broth until it reaches the desired, pourable, and glossy consistency. Add liquid sparingly, as a little goes a long way.
  • Can I use frozen tofu? Yes, you can! Freezing and then thawing tofu actually creates a firmer, chewier texture, making it even better at absorbing marinades and sauces. Press the thawed tofu vigorously to remove all excess water before proceeding with the recipe as directed.

Cook Time:
20 minutes
Total Time:
30 minutes
Servings:
4

Ingredients

  • 14 ounces (397 g) extra-firm tofu, pressed and cubed
  • ¼ cup (32 g) cornstarch (for coating tofu)
  • 3 tablespoons oil (e.g., avocado, canola, or grapeseed)
  • 2 garlic cloves, minced
  • 1 green bell pepper, diced
  • 1 red bell pepper, diced
  • 1 yellow bell pepper, diced
  • 4 slices pineapple, cubed (about ½ cup), fresh or canned and drained
  • 1 red onion, diced
  • 1 green onion, sliced (for garnish)

For the Sweet and Sour Sauce:

  • ½ cup (120 g) ketchup
  • ⅓ cup (67 g) granulated sugar
  • ¼ cup (59 ml) white vinegar (or apple cider vinegar)
  • ¼ cup (59 ml) soy sauce (use tamari or coconut aminos for gluten-free)
  • 3 tablespoons cornstarch (for thickening sauce)
  • 3 tablespoons water (for cornstarch slurry)

Instructions

  1. Heat a large skillet or wok over medium-high heat and add 3 tablespoons of oil.
  2. In a bowl, toss the pressed, cubed tofu with ¼ cup cornstarch until evenly coated. When the skillet is hot and oil is shimmering, add the tofu in a single layer. Cook for 5-7 minutes per side, without moving, until golden brown and crispy. Remove tofu and set aside.
  3. In the same skillet (add a touch more oil if needed), add minced garlic, diced bell peppers (green, red, yellow), and red onion. Sauté for about 7-10 minutes, stirring, until softened but still tender-crisp. Add the pineapple chunks during the last few minutes to warm through.
  4. In a separate small bowl or measuring cup, whisk together all sauce ingredients: ½ cup ketchup, ⅓ cup sugar, ¼ cup white vinegar, ¼ cup soy sauce, 3 tablespoons cornstarch, and 3 tablespoons water until smooth (this is your slurry). Pour this mixture into the skillet with the vegetables.
  5. Bring the sauce to a gentle simmer, stirring constantly, and allow it to cook for 2-3 minutes, or until it thickens to a glossy consistency that coats a spoon.
  6. Add the crispy tofu back into the skillet with the vegetables and sauce. Gently toss everything together until all ingredients are well-coated in the luscious sauce.
  7. Remove from heat. Garnish generously with sliced green onion and serve warm, ideally over a bed of fluffy rice. Enjoy your homemade sweet and sour tofu!

Notes

  • To Store: Store leftover sweet and sour tofu and veggies in an airtight container in the fridge for 2-3 days.
  • To Reheat: For best results and to maintain texture, reheat on the stovetop over medium-low heat until warmed through, adding a splash of water or broth if needed to revive the sauce. Microwave reheating is quicker but may yield less crispy tofu.
