Prepare the tofu: If using pre-pressed super-firm or extra-firm tofu, simply pat the block dry. Otherwise, press and pat dry. Cut the tofu into the desired shape. Transfer to a medium bowl.
Preheat the oven to 375ºF.
Make the marinade: Mix the soy sauce, garlic powder, nutritional yeast, 1 tablespoon water, sriracha, oil, and cornstarch (if using). Adjust quantities to taste.
Add the marinade to the tofu: Pour the marinade over the tofu and toss to coat evenly.
Oven-Bake: Line a rimmed baking sheet with parchment paper or an oven-safe silicone mat, or use a nonstick sheet. Spread the tofu in an even layer.Bake for for about 25 minutes, or until the desired texture, flipping halfway through.
For serving: Enjoy as is to boost protein in salads, grain bowls, or veggie bowls.
Notes
Seasoning tip: Use 1 ½ to 3 tablespoons low-sodium soy sauce or tamari, to taste.
Place the tofu in a single layer for cooking with enough space in between for the hot air to pass freely. This ensures even browning.
Storage: Refrigerate any leftover cooked tofu in an airtight container for up to 4 days.
