What Makes Katsu Sauce So Good?

Sweet and tangy, with a bit of a bite, perhaps the best way to think about this recipe is as a Japanese version of barbeque sauce. In fact, most people know Katsu Sauce as the brown dipping sauce that comes with Katsu, a very popular fried pork cutlet dish with very Western origins.

Katsu first appeared in Japan during the 19th century after a local cook freely adapted a dish he had while traveling abroad to better reflect Japanese tastes.

Katsu sauce is, therefore, not a traditional sauce, being much brighter and more flavorful than other typical Japanese sauces. It is this uncharacteristic tang that is so essential to help balance out the richness of Katsu.

It Has Another Name: Tonkatsu Sauce

Don’t ask for extra katsu sauce at your local Japanese restaurant because there is a chance your waiter won’t understand what you mean. The reason is that although most people just call the breaded pork cutlet “katsu”.

The actual Japanese name for the dish is tonkatsu. Tonkatsu is a direct translation meaning “pork cutlet.” So this recipe can be used when you want to make an easy tonkatsu sauce.

  • Garlic

Ingredient Notes

Use a dark soy sauce, sometimes labeled as koikuchi, for this recipe. It has the right balance of umami flavor and saltiness. The Kikkoman brand is widely available and works well in this sauce recipe.

Mirin is a type of rice wine, and it’s a common ingredient in Japanese cooking. Authentic mirin is not cheap, but you can find less expensive versions online that taste similar and work well enough for this recipe. If you can’t find any mirin, you can use dry sherry in its place.

Go ahead and use ordinary Worcestershire sauce, but if you can get your hands on a bottle of Japanese-style Worcestershire sauce, try that instead. You’ll notice a huge difference in flavor. A famous brand of Japanese-style Worcestershire that you can sometimes find in the supermarket is Bull-Dog sauce, but any Japanese-style Worcestershire sauce will do.

How To Serve Katsu Sauce

To elevate your homemade Katsu Sauce, stir a tablespoon or two of toasted sesame seeds into the sauce.

Serve the sauce in a small bowl as you would a dipping sauce or in a small pitcher so it can be poured over the dish.

What To Serve Katsu Sauce With?

You will often find a small bowl of tonkatsu sauce served alongside a breaded and pan-fried pork cutlet and a lightly dressed cabbage salad. But that is not the other way to enjoy this recipe.

The sweet and sour flavor pairs well with any fried food. Use it as an Asian-style dipping sauce for chicken nuggets and tenders or even homemade tater tots. It is also particularly good in place of the white gravy on top of chicken fried steak.

How To Store Homemade Katsu Sauce?

Keep this sauce in a covered bottle in the fridge for up to 2 months.
