Homemade Tonkatsu Sauce: The Ultimate Japanese Barbecue Companion

Authentic Japanese Tonkatsu BBQ Sauce Recipe

Elevate your crispy panko-crusted cutlets with this irresistible homemade tonkatsu sauce!

Ever found yourself with a delicious piece of katsu but no sauce to accompany it? That’s exactly what happened to me, and it led me on a quest to create the perfect tonkatsu sauce at home. Now, I’m sharing this culinary treasure with you!

Despite its complex flavor profile, this sauce is surprisingly simple to whip up. While it’s a staple in Japanese cuisine, its roots actually trace back to British Worcestershire sauce. Our version is a sweeter, thicker twist on this classic condiment.

The magic of this sauce lies in its perfect balance of flavors. Ketchup and Worcestershire form the base, while soy sauce adds a salty depth. A touch of mirin and sugar bring sweetness, and mustard and garlic powder round out the profile with a subtle kick. The result? A sauce that’ll make you wonder why you ever settled for store-bought!

  • 1 tablespoon (15g) granulated sugar
  • 2 teaspoons Dijon mustard
  • 1/4 teaspoon garlic powder


  1. In a small bowl, combine ketchup, Worcestershire, soy sauce, mirin, sugar, mustard, and garlic powder. Stir until all ingredients are well incorporated. Your tonkatsu sauce is ready to use!
