Pat the tofu dry and cut into cubes.

Preheat the oven to 350°F (175°C) and lightly grease a baking sheet.

Heat a small skillet over medium heat. Toast the sesame seeds until fragrant, about 1-2 minutes.

In a large bowl, toss the tofu cubes with soy sauce, ginger, and toasted sesame seeds until evenly coated.

Spread the tofu on the prepared baking sheet and bake for 15 minutes. Flip the cubes and continue baking until firm and heated through, about 15 minutes more. Serve.
