Why this recipe works
- Quick and easy. This recipe comes together in under a minute and doesn’t require any cooking at all.
- Just 4 ingredients. Simple and easy-to-find ingredients you’d probably already have in your pantry.
- Better than store-bought! Sure, you can buy a bottle of this sauce at any Asian grocery store but making it homemade is so much better.
What I love about this recipe is just how versatile it is! Like our eel sauce, we’ve often used it as a dipping sauce for sweet potato fries and have even known to add it to our sandwiches for a delicious umami hit.
What is katsu sauce?
Katsu sauce, also known as tonkatsu sauce, is a Japanese sauce and condiment. It is used with many types of fried chicken, like karaage (Japanese fried chicken) and katsu don (deep-fried chicken or egg over rice).
It’s like Worcestershire sauce, but much more flavorful and, personally, much more delicious!
As mentioned earlier, this homemade katsu sauce needs just four ingredients to make. Here is what you’ll need:
- Ketchup. Makes the sauce sweet and tangy; you can also use tomato sauce.
- Worcestershire sauce. Adds a strong and smoky flavor that balances out the sweet elements.
- Powdered sugar. Dissolves much easier than granulated sugar and adds some sweetness.
- Soy sauce. I like to use low-sodium soy sauce, but any soy sauce works. Avoid using dark or flavored sauces as these tend to be sweeter.
How to make katsu sauce?
While you can buy store-bought katsu sauce at mainstream supermarkets, making your own is pretty much foolproof!
Mix: Add all the ingredients to a bowl and mix well.
Serve and store: Either serve immediately over some chicken katsu or store away to use later.
What goes with tonkatsu sauce?
In burgers: After using the sauce in a katsu burger, we added it to all our burgers, especially a wagyu burger or bison burger. As they are so gamey, the sweet and savory sauce compliments it so well.
As a sandwich spread: The next time you reach for mayonnaise or mustard for your sandwich, try a thin layer of this sauce and thank me later.
To store: Leftovers can be stored in the refrigerator, covered, for up to four weeks.
To freeze: Place the sauce in a glass or airtight container and store it in the freezer for up to 6 months.

Katsu sauce has a tangy, umami taste. It’s slightly spicy but not overly so, because sugar balances the spice level. However, if you like your sauce when it’s spicy, you can add red pepper powder or flakes.
