Drain and press the tofu for at least 30 minutes to remove excess moisture. This step is crucial to ensure the tofu crisps properly and absorbs more marinade.
Whisk together soy sauce, freshly grated ginger, minced garlic, maple syrup, and sesame oil in a bowl to prepare the marinade. This glossy glaze delivers a perfect balance of savory, sweet, and aromatic notes.
Cut the pressed tofu into even cubes. Lightly dust with cornstarch to boost crispiness, then toss to coat evenly.
Place the coated tofu cubes in a single layer in the preheated air fryer. Cook at 375°F (190°C) for 12-15 minutes, shaking the basket halfway to ensure even crisping.
Brush the ginger soy marinade over the hot tofu pieces right after air frying. Return to the air fryer for an additional 2-3 minutes to set the glaze.
Let the tofu rest briefly before serving to allow the glaze to thicken and the tofu to retain its crisp texture. Serve warm.
