I am obsessed with crispy sweet and sour tofu because the contrast between crunchy, caramelized edges and that glossy, sticky sauce makes my mouth sit up. I love how extra-firm tofu holds its shape so every bite is meaty and satisfying.

Pineapple chunks give it a bright, juicy hit that cuts through the syrupy glaze and makes the whole dish sing. But what really hooks me is the sticky, tangy dance on my tongue that keeps me reaching back for another cube.

Messy, loud eating encouraged. No guilt.

Just pure, plant-based indulgence I actually want for dinner every weeknight now.

How to Make this

Print Recipe (No Advertisments)

1. Preheat air fryer to 400°F (200°C). If tofu is not already pressed, press it, then cut into 1 inch cubes.

2. In a bowl toss tofu cubes with 1 tbsp neutral oil, 2 tbsp cornstarch, salt and freshly ground black pepper to coat evenly.

3. Arrange tofu in a single layer in the air fryer basket and air fry for 12 to 16 minutes, turning halfway, until golden and crispy. Cook in batches if needed.

4. While tofu cooks, combine 3 tbsp ketchup, 1/3 cup rice vinegar, 1/4 cup tamari or soy sauce, 1/4 cup maple syrup, 2 tbsp brown sugar, 1 tbsp grated ginger, 2 minced garlic cloves, 1 tsp Sriracha, and 1/2 cup water in a bowl and whisk until smooth.

5. Heat a large skillet or wok over medium heat and add the red and yellow/orange bell pepper pieces. Sauté for 3 to 4 minutes until slightly softened.

6. Add 1 cup pineapple chunks to the skillet and cook 1 to 2 minutes until warmed through.

7. Pour the sauce into the skillet with the peppers and pineapple, bring to a simmer, then stir in the cornstarch slurry (2 tsp cornstarch mixed with 2 tbsp cold water). Cook 1 to 2 minutes until the sauce thickens and becomes glossy.

8. Add the crispy tofu to the skillet and gently toss to coat every piece in the sweet and sour sauce. Cook 1 more minute to heat through and meld flavors.

9. Serve immediately over rice or noodles if desired, and garnish with thinly sliced green onions and 1 tsp sesame seeds if using.

FAQ

Q: What type of tofu should I use and how do I prepare it?

A: Use firm or extra firm tofu. Press for at least 20 to 30 minutes to remove excess water, then cut into 1 inch cubes. Toss with 1 tbsp oil, season with salt and pepper, and coat evenly with 2 tbsp cornstarch before cooking.

Q: Can I make the tofu crispy without deep frying?

A: Yes. Air fry at 400 F for 12 to 18 minutes, shaking halfway, or bake on a lined sheet at 425 F for 25 to 30 minutes, flipping once. Both methods yield crisp tofu when coated with cornstarch and lightly oiled.

Q: How do I get the sauce to the right thickness?

A: Cook the sauce ingredients first, then stir in the cornstarch slurry (2 tsp cornstarch mixed with 2 tbsp cold water) and simmer until glossy and thickened, about 1 to 2 minutes. If too thin, add a touch more slurry; if too thick, thin with a splash of water.

Q: How can I make this gluten free or lower in sodium?

A: Use tamari instead of soy sauce for gluten free. Choose low sodium tamari or soy sauce and reduce added salt to lower overall sodium.

Q: How long will leftovers keep and how should I reheat them?

A: Store tofu and sauce separately in airtight containers in the fridge for 3 to 4 days. Reheat in a skillet over medium heat until hot to preserve crispness. For extra crispness, reheat tofu in the oven or air fryer and warm the sauce on the stove.

Q: Can I adjust the sweetness or heat?

A: Yes. Reduce maple syrup and brown sugar for less sweet, or add more for sweeter. Increase or decrease the Sriracha to adjust heat, or substitute a milder chili paste if you prefer.

Crispy Sweet And Sour Tofu Recipe Substitutions and Variations

Tofu: swap with tempeh for firmer texture and nuttier flavor, or cauliflower florets for a vegetable option.
Cornstarch (for coating or slurry): use arrowroot powder, tapioca starch, or potato starch in equal amounts.
Rice vinegar: substitute apple cider vinegar or white wine vinegar at a 1:1 ratio; a mild lemon juice can also work in a pinch.
Maple syrup: replace with honey, agave nectar, or extra brown sugar mixed with a little water to reach a similar consistency.

Pro Tips

– Press the tofu at least 30 minutes, preferably wrapped in towels with a heavy pan on top. The drier the tofu, the crisper it will get and the less likely it is to fall apart when you toss it with sauce.

– Toss the tofu with a little oil before the cornstarch so the coating sticks evenly. Shake out excess cornstarch before air frying for a light, crunchy crust rather than a gummy one.

– Do not overcrowd the air fryer. Cook in a single layer with space between pieces and work in batches if needed. Turning halfway through ensures all sides get golden without steaming.

– Taste and tweak the sauce before thickening. If it is too sharp add a touch more maple syrup or brown sugar; if too sweet add a splash more rice vinegar or a little extra tamari for depth. Add the cornstarch slurry slowly until you reach the glossy, clingy texture you want.

– Toss the tofu into the sauce just long enough to coat, then serve immediately so the crust stays crisp. If you need to hold it a short time, keep tofu on a warm tray in a single layer so steam does not soften it.
