Press the tofu: Wrap the block in a clean towel and place something flat and heavy on top for 15–20 minutes.
This helps remove moisture so the tofu crisps up nicely.
Preheat the air fryer: Set it to 400°F (200°C) for 3–5 minutes. A hot basket gives you better browning.
Cut and season: Slice the pressed tofu into 1-inch cubes. In a bowl, toss with soy sauce, oil, garlic powder, onion powder, salt, and pepper until evenly coated.
Coat with cornstarch: Sprinkle 2 tablespoons cornstarch over the tofu and toss gently.
The light coating is what delivers that crisp exterior.
Air fry: Arrange tofu in a single layer in the basket. Don’t crowd. Cook for 10–14 minutes, shaking the basket halfway, until golden and crisp on the edges.
Thicker cubes may need an extra 1–2 minutes.
Make the bang bang sauce: While the tofu cooks, whisk together mayo, sweet chili sauce, sriracha, lime juice, and honey or maple (if using). Taste and adjust salt, sweetness, or heat.
Optional crisp booster: If your tofu looks pale, mix 1 tablespoon cornstarch with 1 tablespoon water, drizzle lightly over hot tofu, shake, and air fry 1–2 more minutes. This forms a thin, extra-crispy shell.
Sauce it up: Toss the hot, crispy tofu with just enough bang bang sauce to coat.
Or serve the sauce on the side to keep the crust extra crunchy.
Garnish and serve: Top with green onions and sesame seeds. Serve over rice with cabbage or greens, and a squeeze of lime.
