What is Katsu Sauce?

Katsu sauce is a sweet and savory dipping sauce with a base of soy sauce, Worcestershire sauce and ketchup and seasoned with brown sugar and minced garlic. While it is not as widely used, or even known, in Western countries, it’s one of the more popular condiments in Japan served with a wide variety of dishes.

However, I would say katsu sauce is most commonly associated with tonkatsu (Japanese fried pork cutlets) and chicken katsu (Japanese fried chicken cutlets). That being said, I also its tangy flavor goes well with gyukatsu, or fried Japanese steak.

How to Make Katsu Sauce?

Making katsu sauce is very simple and most of the time is spent letting the sauce rest giving all the flavors a chance to meld together.

1. Assemble the ingredients. Katsu sauce is made with 1/2 cup of ketchup, 1/4 cup of soy sauce, 1/4 cup of Worcestershire sauce, 1 tablespoon of brown sugar, and two cloves of minced garlic. When cooking more complex dishes I usually pre-measure all ingredients so I can add quickly. However, with this sauce you can probably just measure directly into a mixing bowl as needed.

Assemble all the ingredients for katsu sauce.

2. Mix soy sauce, Worcestershire sauce, minced garlic, and brown sugar into a mixing bowl until the sugar is dissolved.

Add soy sauce, Worcestershire sauce, garlic and brown sugar to a mixing bowl and stir until combined for katsu sauce.

3. Add ketchup and mix until the sauce is fully combined.

Add ketchup to katsu sauce and stir to combine.

4. Cover and let sit for at least 20 minutes. The longer the better as the sauce will only taste better the longer it sits.

Cover katsu sauce and let sit for at least 20 minutes.

5. After the sauce has rested for at least 20 minutes it is ready to serve!
