Gyukatsu is a tender beef steak that has been coated in breadcrumbs and deep fried, it's crunchy and golden on the outside while being juicy and rare on the inside. Make this restaurant style dish at home for a fraction of the cost!
Spread half of the grated onion in a container, place the steak on top and use the other half to coat the top of the steak. Rest in a cool place for 30 minutes (not the refrigerator).
Mix the soy sauce, red wine, mirin, ginger paste and garlic paste in a small saucepan. Bring to a boil and bubble for 1 minute. Remove from the heat and set aside.
