Preheat the oven to 425 degrees Fahrenheit.
Remove the tofu from the package.
Place it between two towels or a few paper towels and put a heavy object on top. (See notes for suggestions)
Let the extra liquid press out of the tofu for ideally 30 minutes. If you're in a hurry you can safely skip this step, but even just a few minutes will really help the tofu crisp up well!
Once pressed, cut the tofu into cubes and add to a bowl.
Toss with the soy sauce, breadcrumbs and corn starch and make sure every piece is well coated.
Add to a baking sheet lined with parchment paper. Try to make sure none of the tofu cubes are touching. This ensures they get nice and crispy and don't stick together.
Bake for 25-30 minutes or until golden brown.
During the final 15-20 minutes of baking, prepare the sauce. When the tofu is done, let it cool for about 5 minutes.
When the tofu is done, transfer to a bowl and toss with about 2/3 of the sauce, saving a bit to add to rice and veggies if desired. Serve immediately and enjoy!
