Star Ingredients and Substitutions

Discover the key ingredients that make sweet and sour tofu triangles so delicious. From fresh vegetables to flavorful sauces, these components bring everything together. Here’s what makes this dish a favorite for any meal, any time of the week:

Ingredients for sweet and sour tofu with labels.
  • Extra-Firm Tofu (10-ounce block): Choose an extra-firm tofu block, around 10 ounces, ensuring it’s thoroughly drained and pressed to remove excess moisture. Cutting it into triangular pieces allows for better absorption of flavors and a satisfying texture upon cooking. If you prefer the taste and texture of tempeh, you can swap out the tofu for tempeh (such as this air-fryer tempeh) as a hearty, protein-rich base.
  • High-Heat Oil (Toasted Sesame Oil): Harness the rich, nutty essence of toasted sesame oil. As an oil with a high-heat point, it’s perfect for frying and sautéing. You could also use peanut oil, if you’re not able to find toasted sesame oil.
  • Aromatic Blend (Onion, Garlic, Ginger): The foundation of the sauce begins with a flavorful trio: onions, garlic, and ginger. One medium onion, finely chopped, infuses a savory sweetness. Mince a clove of garlic to release its pungent aroma, complemented by the warmth of grated ginger, approximately a 1-inch piece. Together, they form a fragrant base that enhances the overall complexity of the dish.
  • Sweet and Sour Sauce (Tamari or Soy Sauce, Maple Syrup, Rice Vinegar, Lemon Juice): The sauce marries sweet, salty, and tangy notes, creating a harmonious blend of flavors. Start with tamari or soy sauce for its rich umami depth. Balance the saltiness with maple syrup (or sugar), providing a natural sweetness. Introduce rice vinegar for a bright, acidic kick, complemented by the juice of half a lemon for freshness. This combination results in a sauce that tantalizes the taste buds.
  • Thickening Agent (Cornstarch): Achieve the desired consistency of the sauce by adding cornstarch. This thickening agent transforms the liquid components into a truly luscious coating.
  • Garnish (Scallions and Sesame Seeds): Boost the visual appeal and freshness of the dish with chopped scallions and sesame seeds (black or white would both work well) as a garnish.

How To Make

Step 1: Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper and arrange the tofu triangles on it. Bake for 12 to 15 minutes, until they’re lightly browned.

Tofu FAQs

How do I store any leftover sweet and sour tofu?

This recipe is best eaten the same day, but you can store any leftover tofu in a covered container in the fridge for a few days. If there’s any remaining sauce, try to store that in a mason jar so that you can use it to help heat up your tofu another day. Not recommended for freezing.

Can I prep this tangy tofu recipe ahead of time?

You sure can! To make cooking quicker, you can prep the sauce and cut the tofu into triangles the day before. Keep each in a separate, sealed container until ready to use. Check out our Tofu Guide for the Tentative Cook for more tips on tofu!

Help! How do I cut tofu into triangles?

This video shows how to cut tofu in four different ways, just in case you don’t like triangles. You can also do it this way:
1. Cut the tofu block vertically into 2 thick slices.
2. Then, cut through the center of these so that you have 4 thick blocks.
3. Turn each block on its end and cut through it diagonally – making two long triangular shapes.
4. Slice each of the two long triangular shapes into 1/4″ thick slices. Repeat for the other 3 blocks.

Alternatively, you can rip the tofu into chunks that resemble pieces of chicken, so the finished dish will look very similar to sweet and sour chicken.

Prep Time 15 minutes
Cook Time 30 minutes
Total Time 45 minutes
Servings 3

Ingredients

  • 1 (14-ounce) package extra-firm tofu, drained, pressed, and cut into triangles
  • 2 teaspoons sesame oil
  • 1 medium onion, chopped
  • 1 clove garlic, minced
  • 1 1-inch piece ginger, grated
  • 1 medium carrot, peeled and chopped into matchsticks
  • 4 tablespoons soy sauce
  • 3 tablespoons maple syrup
  • 3 tablespoons rice vinegar
  • 1 lemon, juiced
  • 1 tablespoon tomato paste
  • ¼ cup water
  • 1 tablespoon cornstarch
  • 2 tablespoons sesame seeds
  • Chopped scallions, for garnish

Instructions

  • Preheat the oven to 400°F (200°C) and line a baking sheet with parchment paper. Place the tofu triangles on the prepared baking sheet evenly spaced and bake for 12 to 15 minutes, until they turn light brown.
  • While the tofu is baking, heat the sesame oil in a nonstick frying pan over medium-high heat. Add the onion, garlic, ginger, and carrot, and sauté for 4 to about 5 minutes, or until the vegetables soften and the onion becomes translucent.
  • Prepare the sauce by mixing together the soy sauce, maple syrup, rice vinegar, lemon juice and tomato paste in a small bowl. In a separate bowl, whisk together the water and the cornstarch.
  • Once the tofu is baked, add it to the pan and cook for 5 minutes, rotating each triangle frequently for even cooking. Pour the sauce into the frying pan and stir well to coat the tofu. Let it simmer for a few minutes, then pour in the cornstarch slurry and stir until the sauce thickens.
  • Remove from heat and stir in the sesame seeds, garnish with scallions and serve with a side of your choice.

Notes

It’s important to get as much water as possible out of the tofu. Depending on the brand you use, pressing may be necessary. You can also freeze it overnight to get a firmer and chewier texture.

    This tofu is SO flavorful and scrumptious. I also like cutting the tofu into cubes instead of triangles because it makes the recipe just a little bit faster and easier for me 🙂

  8. 5 stars
    I love a good sweet and sour dish, especially when tofu is involved! Yum!

    This was really delicious! But the steps of the recipe are quite confusing. What do you do with the vegetables in step 2? Just leave them in the pan? How does this relate to the tofu in a (separate?) pan in step 4? Step 4 says the tofu is in cubes, not triangles, and I think cubes would be a better shape for this dish. The vegetables in step 2 need to be added at the end of step 4, unless we are using the same pan throughout. I solved these odd directions by cooking vegetables and then adding the baked tofu and the sauce–I didn’t see the point of frying baked tofu. I used super firm tofu and tapioca starch instead of cornstarch. I will definitely make this again using cubes of tofu!

    • So glad you liked it, Rebecca! And thanks so much for your feedback, I adjusted how the recipe is written to try to make it more clear for others who make this dish 🙂 Cheers!!
