Pat tofu dry with paper towels, then place tofu brick on a paper towel-lined plate.
Cover with an additional folded paper towel, then another plate. Weigh down the top plate with something heavy, like a can of tomatoes.
Let sit for 10-15 minutes, then pat tofu dry again.
Slice the tofu into ¾-inch or 1-inch cubes.
Line a baking sheet with parchment paper or nonstick aluminum foil.
Stir together oil, soy sauce, cornstarch, salt, and garlic powder in a medium bowl until cornstarch dissolves.
Add tofu, and toss together gently using your fingers.
Place tofu cubes onto sheet pan, leaving any extra liquid behind in the bowl.
Bake for 15 minutes, then turn tofu cubes over.
Bake for another 5-10 minutes, until tofu is crispy and golden-brown.
Notes
How to Store: Your tofu cubes will last 3-5 days in the refrigerator in an airtight container.How to Reheat: If you have leftover crispy tofu, the best and fastest way to reheat it is to pop it in the air fryer for a few minutes. If you don’t have an air fryer, reheating in a hot oven on a baking sheet or reheating in a hot skillet is the best way to get the tofu cubes crispy again!Expert Tip: We recommend cutting your tofu into fairly large cubes. If you choose to cut the tofu into small cubes, they will cook faster. However, with small cubes, you won’t get the delightful contrast between the crunchy outside and the creamy inside.
