Ingredient Tips
Refer to the recipe card for the full list of ingredients and measurements!
- ketchup – Some brands of ketchup may be sweeter than others; therefore, I would adjust the amount of sugar accordingly.
- oyster sauce – my favorite oyster sauce is by Lee Kum Kee. They make a great vegan version as well!
- brown sugar – this will be to taste, so start with less than 1 tbsp and add accordingly. I like my Homemade Tonkatsu (Katsu) Sauce on the less sweet side but you may prefer a sweeter version! You may also find that your ketchup is not as sweet as some other brands (noted above).
Next time you make my juiciest, crispiest Chicken Katsu (or my Air Fryer Chicken Katsu, if you don’t feel like deep frying) or Pork Katsu (Tonkatsu) with Hawaiian Mac Salad on the side, make sure to also make my Homemade Tonkatsu (Katsu) Sauce and see how perfectly it goes! I also love it with Mochiko Chicken!
PRO TIPS
Expert Tips + Storage
- Use high-quality ingredients: The quality of your ingredients will greatly affect the flavor of your sauce. Choose a good quality ketchup, Worcestershire sauce, and oyster sauce for the best results.
- Adjust the sweetness and saltiness to your liking: The recipe above is just a guide, so feel free to adjust the sweetness and saltiness of the sauce to your liking. Some people prefer a sweeter sauce, while others prefer a saltier sauce.
- Let the flavors meld: It’s important to let the 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.
- Use as a dipping sauce or drizzle it over dishes: Tonkatsu sauce is a versatile sauce that can be used as a dipping sauce for katsu or drizzled over vegetables, salads, or other dishes.
Storage Tips
When I make my homemade Tonkatsu (Katsu) Sauce, I like to double or triple the portion so it’s easily accessible whenever I want it! Therefore, it’s important to discuss how to store your delicious sauce.
Once mixed, store your homemade Tonkatsu (Katsu) sauce in an airtight container in the refrigerator. (This must be refrigerated!) In an airtight container, it can be stored in your refrigerator for up to 1 month. NOTE: Make sure to avoid dipping directly into your Tonkatsu (Katsu) Sauce container; you want to avoid any cross-contamination or crumbs in your sauce!
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 or Chick-Fil-A Sauce, and homemade BBQ Sauce!
