Press the tofu to remove excess moisture. Wrap the block in clean kitchen towels or paper towels, place a heavy object (like a cast iron pan) on top, and let sit for at least 15 minutes. This crucial step ensures your tofu gets crispy instead of soggy.
Cut the pressed tofu into 1-inch cubes or your preferred shape. The size affects cooking time—smaller pieces cook faster and get crispier all around.
Preheat your air fryer to 400°F (200°C) for 3-5 minutes. Proper preheating creates that immediate searing effect that helps with crispiness.
In a large bowl, toss the tofu with olive oil until evenly coated. The oil helps the seasonings stick and promotes browning, but don’t drench it.
Sprinkle cornstarch over the tofu and gently toss until every piece has a thin, even coating. This creates that magical crispy exterior.
Add all seasonings (garlic powder, onion powder, salt, pepper, and any optional ingredients) and toss again until tofu is evenly coated. Make sure there are no clumps of seasoning.
Place the tofu in a single layer in your air fryer basket, making sure pieces aren’t touching. Work in batches if necessary—overcrowding prevents proper air circulation and crispiness.
Air fry for 10 minutes, then shake the basket or flip the tofu pieces. This ensures even browning on all sides.
Continue cooking for 5-10 more minutes until the tofu reaches your desired level of crispiness. The exact time depends on your air fryer model and how crispy you prefer your tofu.
Serve immediately for maximum crispiness, or let cool slightly before adding to your favorite dishes.
