Ingredients for Homemade Tonkatsu Sauce

Homemade Tonkatsu (Katsu) Sauce only requires 4 ingredients – and they are all pantry staples you probably already have at home! Most people may think that it’s complicated to make homemade Tonkatsu (Katsu) Sauce at home, or that you would need a lot of ingredients, so they buy the store-bought version. But after trying this recipe, you’ll see that is not the case!

  • 1/2 cup ketchup – Some brands of ketchup may be sweeter than others; therefore, I would adjust the amount of sugar accordingly.
  • 1/4 cup Worcestershire sauce
  • 2 tbsp oyster sauce – my favorite oyster sauce is by Lee Kum Kee.
    • They make a great vegan version as well!
  • 1 tbsp 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).
