A Note from CJ
You have to try my Homemade Tonkatsu Sauce!
I love my homemade katsu sauce – it’s so easy and tastes better than store bought sauces! Make sure to try my Homemade Tonkatsu (Katsu) Sauce next time you make crispy Chicken Katsu (or my Air Fryer Chicken Katsu), juicy Pork Katsu (Tonkatsu), or crunchy Mochiko Chicken with Hawaiian Mac Salad on the side!
I love making my own Sauces and Condiments at home as possible! My go-tos are Sweet and Sour Sauce, Sichuan Chili Oil, homemade Ranch, copycat Raising Cane’s Sauce, Chick-Fil-A Sauce, and homemade BBQ Sauce!
The best tasting katsu sauce with perfect balance, and so easy to pull together!
Ingredient Tips & Instructions
Refer to the recipe card for the full list of ingredients and measurements!
- ketchup – Some brands of ketchup are sweeter than others; adjust the amount of sugar accordingly.
- oyster sauce – my favorite oyster sauce is by Lee Kum Kee – get the one with the lady on the label (not the panda!)
- brown sugar – this will be to taste, so start with less than 1 tbsp and add if needed (especially if your ketchup is on the sweeter side).
Making katsu sauce is so simple – mix together the ingredients in a small bowl until smooth. I recommend chilling the tonkatsu sauce in the refrigerator for at least 15-30 minutes before serving – this will help the flavors further meld together.
PRO TIPS
CJ’s Recipe & Storage Tips
Adjust to your liking – Some brands of ketchup are sweeter than others – make sure to taste the sauce and adjust to your liking. This is also dependent on if you like your sauce on the sweeter or saltier side!
Let the flavors meld – It’s important to let the tonkatsu sauce chill in the refrigerator for at least 30 minutes before serving. This will allow the flavors to meld together and create a more cohesive sauce.
Storage – Once mixed, store your homemade Tonkatsu (Katsu) sauce in an airtight container in the refrigerator for up to 1 month. Avoid dipping directly into the sauce container; you want to avoid any cross-contamination or crumbs in your tonkatsu sauce!
