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).
Gather all the ingredients. I included a bottle of Bull-Dog Tonkatsu Sauce in the image, but it‘s not needed for this recipe.
In a jar or small bowl, combine 4½ Tbsp Worcestershire sauce and 2 Tbsp sugar. Whisk well until the sugar is completely dissolved.
Then, add 5 Tbsp ketchup and 2 Tbsp oyster sauce and whisk until combined. Taste the sauce and adjust the seasoning. Some ketchup is sweeter than others, so please adjust the amount of sugar to taste. It's now ready to use.
