Open and drain tofu. Press tofu on a tofu press or wrap in a clean tea towel and place until a heavy object. Press the extra moisture out for 10 minutes.

Cut tofu into 1/4inch thick rectangles and lay on a large flat surface with a lip, like a 9x13 baking pan. Whisk together soy sauce, rice vinegar, maple syrup, sesame oil, ginger, garlic and chili flakes.

Pour half marinade over tofu. Flip and pour on other half. Let the tofu sit in marinade for 30 minutes to soak up as much marinade as possible.

Preheat oven to 425F and line a baking sheet with parchment paper. Remove tofu from marinade and arrange on the baking sheet with space between each piece.

Bake at 425F for 25 minutes. Allow to cool slightly and enjoy!
