Drain the tofu and slice it into 1/4-inch rectangles. Pat dry with a paper towel.

Combine soy sauce, sugar, minced garlic, Korean red chili powder, and pounded red chili in a mixing bowl. Stir in water and add white sesame seeds.

Heat a non-stick skillet over medium heat, add oil and fry tofu slices for 3-4 minutes until golden brown.

Flip tofu slices and cook for another 3-4 minutes until crispy.

Pour in the prepared sauce and simmer for 2-4 minutes, coating the tofu.

Transfer tofu to a serving platter, drizzle with remaining sauce and garnish with green onion.
