Chicken katsu sauce, also known as tonkatsu sauce, is a deliciously tangy, sweet, and savory condiment that perfectly complements crispy chicken katsu or any other deep-fried dishes. Making your own homemade chicken katsu sauce is not only easy but also allows you to customize the flavors to suit your taste preferences. In this comprehensive guide, we’ll walk you through the step-by-step process of creating this delectable sauce right in your own kitchen.

Air Fryer Chicken Katsu With Tonkatsu Sauce

Chicken katsu sauce is a staple condiment in Japanese cuisine, often served alongside deep-fried cutlets like chicken katsu or tonkatsu. Its rich flavor profile combines the tanginess of ketchup, the umami depth of Worcestershire sauce, the sweetness of sugar, and the savory notes of oyster sauce or soy sauce. While store-bought options are readily available, crafting your own homemade version allows you to control the ingredients and achieve a sauce that perfectly suits your palate.


  • Ketchup: 1/4 cup
  • Worcestershire Sauce: 2 tablespoons
  • Sugar: 1/2 tablespoon
  • Oyster Sauce or Soy Sauce: 1 tablespoon

Step-by-Step Instructions

Chicken Katsu

1. Gather Your Ingredients

Before starting the sauce-making process, ensure you have all the necessary ingredients gathered in your kitchen. This includes ketchup, Worcestershire sauce, sugar, and oyster sauce or soy sauce. Having everything prepared and within reach will make the process smoother and more efficient.

2. Measure Ingredients

Accurate measurement of ingredients is key to achieving the desired flavor balance in your chicken katsu sauce. Use measuring cups and spoons to measure out the specified quantities of each ingredient according to the recipe. Adjust the amounts based on your taste preferences, keeping in mind the desired sweetness, tanginess, and umami depth of the sauce.

3. Combine Ingredients

Once you’ve measured out all the ingredients, it’s time to combine them in a mixing bowl. Start by adding the measured quantities of ketchup, Worcestershire sauce, sugar, and oyster sauce or soy sauce into the bowl. Use a spoon or whisk to thoroughly mix the ingredients together until they are well incorporated. Ensure that the sugar is fully dissolved and there are no lumps in the sauce.

4. Taste and Adjust

After combining the ingredients, take a moment to taste the sauce and assess its flavor profile. Pay attention to the balance of sweetness, tanginess, and savory depth. Depending on your preferences, you may need to adjust the flavorings by adding more of certain ingredients. For example, if you prefer a sweeter sauce, you can add a bit more sugar. If you crave more umami richness, consider adding extra Worcestershire sauce or soy sauce. Continue adjusting the flavorings until the sauce reaches your desired taste.

5. Optional Additions

To enhance the flavor and texture of your chicken katsu sauce, you can incorporate optional additions such as toasted sesame seeds or crushed garlic. Toasted sesame seeds add a nutty aroma and subtle crunch to the sauce, while crushed garlic provides a hint of savory complexity. If using these optional ingredients, add them to the sauce mixture and stir until evenly distributed.

6. Store and Serve

Once you’ve achieved the perfect flavor balance, transfer the prepared chicken katsu sauce to an airtight container. Seal the container tightly and refrigerate the sauce until you’re ready to use it. Properly stored, the sauce can last for up to a month in the fridge, allowing you to enjoy its delicious flavor whenever you crave it. When serving, simply drizzle the sauce over crispy chicken katsu or any other deep-fried dishes for a burst of irresistible flavor.
