If you need gluten free panko but can’t find it, you can make gluten free breadcrumbs at home by freezing a piece of gluten free bread and grind it in a food processer until you have fine meshed breadcrumbs.

Katsu Sauce* Grate the ginger. Mince the yellow onion. In a clean bowl, add 1 tablespoon honey, 3 tablespoon oyster sauce, 1-1/2 teaspoon grated ginger, 1-1/2 teaspoon minced onion, 4 tablespoon Worcestershire sauce, 4 tablespoon ketchup, 1-1/2 teaspoon rice vinegar, 1 teaspoon mustard. Mix well.

Sesame Miso* SauceGrind 2 tbsp of sesame seeds with a mortar and pestle. In a mixing bowl, add ground sesame seed, 1 tablespoon miso, 1 tablespoon mirin, 1 tablespoon rice vinegar, 1 tablespoon sake, 1/2 teaspoon honey. Mix it very well

Cut steak into thickness about 3/4 inch

Coat the beef cutlet in potato starch, egg white and panko. Make sure to shake off the excess.

Add steak and fry for about 2 to 3 minutes.
Lower the heat to medium-high so you won’t burn the outside.
I cooked my 3/4 inch beef for 2 minutes. In Japan, gyukatsu is traditionally served medium-rare but adjust according to your liking. Fry longer if you prefer the steak more done.
