My Homemade Tonkatsu Sauce recipe uses only four simple ingredients and is so quick to make! With savory, sweet, and tangy notes, it tastes just as amazing as Japan‘s famous Bull-Dog Tonkatsu sauce. Serve it with tonkatsu (breaded pork cutlets), chicken katsu, or my favorite korokke (potato and beef croquettes).

Enjoy this Homemade Tonkatsu Sauce as a condiment for breaded and/or deep-fried Japanese foods like Tonkatsu, Chicken Katsu, and Korokke (Potato and Meat Croquette) or their baked versions Baked Tonkatsu, Baked Chicken Katsu, and Baked Croquette. Tonkatsu sauce is also an ingredient in recipes like Japanese Hamburger Steak (Hambagu), Keema Curry, and Meat Doria (Rice Gratin).
