Start by pressing the tofu. Drain the water from the package. Place a paper towel on a plate, then place the towel on top of the paper towel. Put another layer of paper towel on top of the tofu, then place something heavy on top of the tofu. I like to do a few cookbooks or my tea kettle. Let sit for at least 15 minutes, longer if possible.
Preheat the oven to 425ºF. Spray a baking sheet with cooking spray and set it aside.
Remove the tofu from your press and cut the block into cubes. I usually do about 1" cubes.
Place the cubes in a bowl. Spray with cooking spray and sprinkle with salt and pepper.
Transfer the cubes onto the baking sheet. Make sure each cube is laying flat and has space on all four sides.
Bake on the center rack for 20 minutes. Flip the tofu and bake for another 15 - 20 minutes until the tofu is crispy.*
Serve immediately with your favorite dish.
* if you want to add flavor/sauces to your tofu, pour it onto the tofu at this stage. Stir it around and continue to cook.
