What is Tonkatsu Sauce?
Tonkatsu sauce (とんかつソース) is a beloved Japanese condiment traditionally made from fruits and vegetables like tomatoes, prunes, and apples, combined with soy sauce, vinegar, and Asian spices. The mixture is simmered down to a glaze-like consistency, resembling a thick and rich Japanese version of Worcestershire sauce. Its tangy, umami flavor pairs beautifully with breaded and fried foods such as Tonkatsu (Japanese deep-fried pork cutlet), Chicken Katsu, and Japanese Croquettes (Korokke).
Why This Recipe Works
- Make as much or as little as you need – Once you understand the ingredient ratios, you can easily adjust the quantity to suit your needs, whether for immediate use or for storage.
- Simple, four-ingredient sauce – While traditional tonkatsu sauce can be labor-intensive, my recipe achieves a similar flavor profile using just a few pantry staples readily available at any grocery store.
- A versatile sauce recipe – The layers of flavor make it an excellent accompaniment for tonkatsu or a flavorful ingredient in other recipes, such as Japanese Hamburger Steak.

Substitutions
- Worcestershire sauce: I use the Lea & Perrins brand, but similar results can be achieved with any brand. For a vegan option, consider using a vegan Worcestershire sauce.
- Sugar: Both white and brown sugar work well, though I often prefer brown sugar for its added molasses flavor.
- Ketchup: Since the sweetness of ketchup can vary, be sure to taste the sauce and adjust the sugar accordingly.
- Oyster sauce: For a vegan alternative, I recommend Lee Kum Kee Vegetarian Stir-Fry Sauce.
How to Make Homemade Tonkatsu Sauce
Preparation
Step 1 – Dissolve the sugar in the Worcestershire sauce. In a small bowl or jar, whisk until the sugar is fully dissolved.
Step 2 – Add the ketchup and oyster sauce. Whisk until smooth and well combined. Use immediately or store in an airtight container in the refrigerator.
Nami’s Recipe Tips
- Chill the sauce before using – While I often prepare it just before serving, letting the sauce chill in the fridge for at least 30 minutes allows it to thicken significantly.
- Adjust the sweetness – Before serving, I taste the sauce to see if it requires more sugar or other flavorings.
Variations and Customizations
- Make it gluten-free: Substitute with gluten-free Worcestershire sauce and oyster sauce.
- Add fresh garlic or ginger: For enhanced flavor, whisk in ½ tablespoon of freshly minced garlic and/or ginger.
- Stir in dry spices: For added complexity, incorporate ¼ teaspoon of garlic powder, onion powder, or ginger powder until dissolved.
Delicious Ways to Use Tonkatsu Sauce
Although this sauce is named after the fried pork cutlets, it is a versatile condiment that complements many dishes. Here are a few suggestions:
- With the main course: Instead of deep-fried cutlets, try my delicious Baked Tonkatsu.
- As a sandwich spread: Use it on a Katsu Sando or Ebi Katsu Burger for added moisture and flavor.
- As a dipping sauce: Pair it with Chicken Cheese Katsu for essential acidity and richness.
- As an ingredient in other recipes: It serves as a (not-so) secret seasoning in my Keema Curry recipe!
Storage Tips
To store: Keep any leftover sauce in an airtight container in the refrigerator for up to 2–3 weeks or in the freezer for 3–4 months. Be sure to thaw completely before use.
