Drain the tofu and slice into 2 or 3 thick slabs. Lay them on a clean towel or paper towels. Cover with another towel and place something heavy on top (like a few cans). Let it sit for 15–30 minutes while you preheat your oven to 400°F.
1 block extra firm tofu
Remove the towels and cut the tofu into bite-sized cubes, rectangles, or triangles—whatever you like.
Place the tofu in a large bowl. Drizzle with olive oil, then sprinkle on the cornstarch, salt, garlic powder, onion powder, and black pepper. Gently toss until every piece is evenly coated.
2 tablespoons olive oil, 1 tablespoon cornstarch, ½ teaspoon garlic powder, ½ teaspoon onion powder, ¼ teaspoon black pepper, 1 teaspoon salt
Line a sheet pan with parchment paper. Spread the tofu in a single layer so the pieces don’t touch.
Bake for 20 minutes. For extra crispy tofu, either broil for 2 minutes at the end or flip the cubes and bake for another 10–15 minutes.
Enjoy immediately or toss into bowls, salads, wraps, or noodle dishes!
