Growing up, whenever we had chicken katsu, tonkatsu, or korokke, we always had the Bulldog brand sauce along with it. And you know what? I never liked it. *gasp* I know. My brothers would pour a bunch on, and I would just very lightly put a few drops on mine. Weird kid. I also didn’t like to dip my fries in ketchup.

Well, I dip my fries in ketchup now, but I like to make my own sauce. It’s super simple to make and keep at home and it makes a great chicken katsu sauce.

This tonkatsu sauce recipe is great because it’s made with ingredients that many people have on hand! Ketchup, butter, worcestershire sauce (can’t pronounce it, but I THINK I spelled it right, haha), soy sauce, and a little bit of garlic powder.

The ketchup base is a great canvas, and the worcestershire sauce adds a very *zingy* taste to it. Like, kind of tangy, kind of a hint of spicy… and the soy sauce brings a little oomph of umami to it.

This sauce can be used for soooo many more things than just tonkatsu. Try it out as a chicken katsu sauce recipe or the next time you make your favorite fried food! Or you can try non fried food. I haven’t tried dipping veggies in it, but I could see it working!

This tonkatsu sauce goes well with my Japanese croquette recipe (korokke), a type of dumpling which uses potatoes inside and beaten egg and Japanese style panko bread crumbs outside . As you can see in the picture above, my 3 year old was loving it!

  1. The British (who invented it) just call it Wooster sauce — the “oo” sounds like “wood” or ” wool. “. thanks for the recipe!

  2. Just a thought, just put it all, including the cold butter into a small non reactive pan or skillet on low heat, stir til combine and some what emulsified. Done. Chill in a small container, and pull from fridge an hour before you need it, and stir. This would be something I would, by default, put in a 1/4 tsp of citric acid also, to temper the spoilage and get a few more weeks to months out of, by leveling out the ph.

  3. i do or lot of my friends in Japan, we do simply use ¨´´ TONKATASU SAUCE¨´ with mayonnaise! This stuff works for everything. Ketchap + mayonnaise is very common to use !
