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).
Open my refrigerator and you’ll find a stash of Japanese condiments and sauces—a mix of store-bought and homemade goodies. Among them is tonkatsu sauce. This condiment is mandatory when it comes to serving Tonkatsu (deep-fried pork cutlet), Chicken Katsu, and more.
In today’s recipe, I’m sharing a simplified version of Homemade Tonkatsu Sauce using only four ingredients. You’re most likely already have them in the pantry so you can whip it up anytime you need. The great thing about making your own is that you can also adjust the sweetness to your liking.

What is Tonkatsu Sauce?
Tonkatsu sauce (とんかつソース) is served with Tonkatsu (deep-fried pork cutlet) and is often used for other deep-fried dishes like Korokke or to make Hambagu sauce.
Tonkatsu sauce mainly consists of vegetables and fruits such as tomatoes, prunes, dates, apples, lemon juice, carrots, onions, and celery. It also includes more than 10 kinds of spices along with soy sauce, vinegar, and sugar. It’s a lot of work to make it from scratch, so most Japanese people would use the store-bought one.
However, if you don’t live near the Japanese/Asian grocery stores or prefer to make your own, you can always count my easy homemade recipe.
The Most Popular Brand
The most popular tonkatsu sauce is the Bull-Dog Vegetable & Fruit Sauce (Tonkatsu Sauce). It’s easy to recognize the signature bulldog logo on the bottle. You can purchase it on Amazon and Japanese or Asian grocery stores.
How to Make Homemade Tonkatsu Sauce
Ingredients You’ll Need
- Worcestershire sauce
- Oyster sauce
Yes, that’s it! The main flavor of tonkatsu sauce comes from Worcestershire sauce and ketchup. Every brand of ketchup has different sweetness, so you may need to adjust the flavor with sugar.
Overview: Cooking Steps
- Mix all the condiments together. I usually combine the Worcestershire sauce and sugar first. Whisk until the sugar is completely dissolved before adding the rest of the condiments.
Okonomi Sauce and Yakisoba Sauce
We have different sauces for Okonomiyaki and Yakisoba although these three sauces are quite similar.
