Rip tofu block into about 2-inch cubes as uniformly as possible.

In a large bowl, combine boiling water with salt & stir to dissolve. Add tofu to fully submerge. Cover with a lid or plate & let it sit for 10 minutes.

In a small bowl, combine salt, garlic powder, onion powder, and white pepper. Set aside.

Preheat air fryer to 190 degrees F.

Drain & pat dry tofu well with paper towels or a kitchen towel. In a bowl, combine tofu, oil, & cornstarch. Sprinkle seasoning mixture onto the tofu & toss together.

Lightly oil the air fryer rack, add tofu into a single layer working in batches if needed to avoid overcrowding. It’s important not to overcrowd, otherwise, the tofu won’t turn crispy. Cook for 12-15 minutes, or until golden brown and crispy, flipping halfway through.

In the meantime, in a small bowl, whisk together the dipping sauce.

Remove tofu from the air fryer, serve with the dipping sauce, & enjoy!
