01 - Wrap the tofu block in a clean towel and place a weight on top. Leave for 10 minutes to remove excess water.
02 - Cut the tofu into 3/4-inch cubes.
03 - In a large bowl, gently toss tofu cubes with cornstarch, olive oil, salt, and black pepper until evenly coated.
04 - Arrange tofu cubes in a single layer in the air fryer basket. Air fry at 400°F for 12–15 minutes, shaking the basket halfway, until golden and crisp.
05 - While tofu cooks, whisk together soy sauce, maple syrup, rice vinegar, sesame oil, garlic, ginger, cornstarch, and water in a small saucepan.
06 - Cook glaze over medium heat, stirring constantly, until thickened and glossy, about 2–3 minutes. Remove from heat.
07 - Transfer crispy tofu to a bowl. Pour the warm soy glaze over and toss gently to coat.
08 - Serve immediately, topped with sesame seeds and chopped green onions.
