Press your tofu, ideally using a tofu press, or place your tofu on a plate, with another plate on top of it and then place something heavy on top of that like a heavy pot or a stack of books. Let the tofu press for 30 minutes so it becomes as firm as possible.

Preheat the oven to 400°F (200°C)

Cut your pressed tofu into cubes and place into a container with a lid.  

Add the cornstarch, nutritional yeast, garlic powder, onion powder, ground ginger, salt and ground black pepper to a bowl and mix together. 

Drizzle the sesame oil over the tofu and then put the lid on the container and rotate it a few times so that the oil is evenly spread.

Add the cornstarch and seasonings mix to the tofu and then put the lid on again and rotate the bowl a few times so that the tofu is evenly coated with the spices. 

Spread the tofu cubes evenly on a parchment lined baking tray.

Bake for 15 minutes and then flip the tofu cubes and bake for a further 15 minutes until deliciously crispy.
