First dice extra-firm tofu into 1-inch cubes.

Then pat dry the tofu cubes with clean paper towels to remove excess moisture. This is important or your coating will fall off.

Next generously season tofu cubes with an even sprinkle of salt, garlic powder, onion powder on both sides.

Then prepare fill one large shallow bowl with cornstarch, a second bowl with beaten egg and the third bowl with panko breadcrumbs.

Generously coat each seasoned tofu cube into the cornstarch first, then beaten egg and panko breadcrumbs last ensuring no bald spots.

Next heat vegetable oil in a large pan on medium heat, around 350 degrees F with a digital instant read thermometer or place a wooden utensil into the oil and if bubbles form, it's time to fry. Fry tofu on each side until golden brown, about 2-3 minutes per side. Transfer the fried tofu to a wire rack or paper-towel lined plate to remove excess oil.

Lastly in a small bowl, combine Katsu sauce ingredients. Enjoy with tofu!
