What is Katsu Sauce?
Katsu sauce is a Japanese condiment served alongside fried chicken cutlets, also known as chicken katsu! If you’ve never tried this dreamy combination before, you’re missing out. Katsu sauce is kind of similar to barbecue sauce, with ketchup as its foundation. It gets mixed with things like Worcestershire sauce, oyster sauce, and garlic and onion powders to really make the flavor pop.
Sugar is added too, just a little bit to balance out all of the flavors. You’re going to love the way it tastes! It’s seriously so good, and perfect for dipping fried foods in or smothering on top of your favorite meat dishes. Need some ideas? Karaage chicken (Japanese fried chicken), crispy shrimp, or egg rolls just to name a few.
Ingredients in Katsu Sauce
It only takes a few ingredients to make katsu sauce, and they’re all really simple and easy to find! It’s just a mix of ketchup, brown sugar, Worcestershire sauce, garlic, and onion. You can of course tweak the ratios to your liking. That’s the beauty of making sauces from scratch!
- Ketchup: Like barbecue sauce, ketchup acts as the base of the katsu sauce. It adds just the right amount of sweetness and acidity.
- Worcestershire Sauce: For a punch of tangy, umami flavor.
- Sugar: So the flavors in your sauce are balanced out. You can add more or less to taste, depending on how sweet you like your sauces.
- Oyster Sauce: Oyster sauce isn’t quite as salty as soy sauce, but has a similar taste. Hoisin sauce can also be used as a substitute.
- Garlic Powder and Onion Powder: For a punch of sharp, savory flavor.
