Cube the tofu into bite-sized pieces, about 1-inch cubes.
Press the cubes. Lay the cubed tofu on a towel or paper towels, cover with another towel, and press gently (or let sit with light weight on top) for 15-20 minutes to remove excess water.
14 ounces extra-firm tofu
Preheat the oven to 425°F and line a baking sheet with parchment paper.
Toss with oil and cornstarch. In a large bowl, toss the tofu cubes with the avocado oil first, then sprinkle the cornstarch over top and toss again until evenly coated.
1 tablespoon avocado oil, 1 tablespoon cornstarch
Season. Add the salt, garlic powder, onion powder, smoked paprika, and black pepper, tossing once more to coat.
