01 - Gently press the tofu, wrapped in a clean kitchen towel with a weighted object on top, for 10 minutes to remove excess moisture.
02 - Slice the pressed tofu into uniform 3/4-inch cubes.
03 - In a sizable mixing bowl, whisk together the soy sauce, sesame oil, garlic powder, and black pepper. Introduce the tofu cubes and delicately toss to ensure an even coating.
04 - Dust the marinated tofu with cornstarch and toss once more until uniformly coated.
05 - Preheat your air fryer to 400°F for 2 minutes.
06 - Arrange the prepared tofu cubes in a single layer within the air fryer basket, ensuring not to overcrowd. Cook in multiple batches if needed.
07 - Air fry for 12 to 15 minutes, shaking the basket halfway through, until the tofu achieves a golden and crispy texture.
08 - Serve immediately, garnished with sesame seeds and chopped green onions if desired.
