Wrap the tofu in paper towels and place it between two plates. Place a heavy book or flying pan on the top plate and press the tofu for 30 minutes.

Remove the paper towels. Cut the tofu into 1-inch cubes and transfer to a large bowl.

Season the tofu with salt and white pepper. Add the sweet potato starch and toss gently with a spatula to coat the tofu. Try not to break up the tofu too much, but it’s okay if the corners crumble. Set aside.

Spray a piece of parchment paper evenly with thin layer of avocado oil and place it in the air fryer basket. Spray the tofu with 1 tablespoon of avocado oil. Transfer the tofu to the parchment paper in an even layer. Air fry for 20 to 25 minutes. After 20 minutes, see if the tofu will easily release from the parchment paper. If not, continue air frying for 5 to 7 minutes more. The tofu should release easily from the parchment paper.

Carefully remove the tofu from the air fryer. Some pieces may need to be peeled off, but they will still be extra crunchy!

Serve the crispy tofu in your favorite sauce, or enjoy it as a crunchy snack!
