Step 1: Prepare the Tofu : Drain the tofu and press it between paper towels or in a tofu press for at least 15–20 minutes to remove excess moisture. Cut the tofu into 1-inch cubes.
Step 2: Season the Tofu : In a bowl, mix soy sauce and sesame oil. Add tofu cubes and toss gently to coat. Sprinkle with cornstarch, garlic powder, paprika, salt, and pepper. Toss again until evenly coated.
Step 3: Bake or Air Fry : Option 1 – Bake: Preheat oven to 400°F (200°C). Arrange tofu cubes on a parchment-lined baking sheet. Bake for 25–30 minutes, flipping halfway, until golden and crispy. Option 2 – Air Fry: Preheat air fryer to 375°F (190°C). Spray basket lightly with oil and air fry tofu for 15–18 minutes, shaking halfway through.
Step 4: Prepare the Sweet Chili Sauce : In a small saucepan, combine sweet chili sauce, soy sauce, vinegar, honey (or maple syrup), and chili flakes. Heat gently over medium heat. Add cornstarch slurry and stir until the sauce thickens slightly, about 2–3 minutes.
Step 5: Toss Together : Add the crispy tofu to the sauce and toss to coat evenly. Cook for an additional minute to allow the tofu to absorb flavor.
