Easy Japanese Katsu Sauce: A Savory Fusion of Flavors, No Passport Required

Oh, boy! Let me tell you about the day I decided to replace wanderlust with culinary exploration, as ludicrous as that sounds! I’m convinced heart and soul that Japan is calling my name, but until I can plan that elusive trip, my kitchen becomes the next best thing, wouldn’t you agree?

So there I was, daydreaming about gazing at cherry blossoms or hanging with the sushi masters – when suddenly, New York life snapped me back to a reality that featured folding laundry and, of course, hungry bellies waiting to be fed. You know, just casual millennial mom stuff, right? Well, can’t dwell on the impossible trip! Time to up the ante on this cooking escapade and embrace a little taste of Japan.

And that, my friends, is how my katsu sauce obsession was born. The ultimate culinary love letter to a place I still haven’t visited. Stay tuned for the following recipe as we embark on a tasty journey through the fine art of katsu sauce. It’s a one-way ticket to creativity and flavor, sans jet lag! So grab your apron, your wanderlust-hungry heart, and a pinch of humor, and let’s dive in!


  1. Ketchup – Adds sweetness and tanginess as the base of the sauce.

  2. Worcestershire sauce – Adds depth of umami flavor and a hint of spice.

  3. Oyster sauce – Brings a unique and subtle seafood taste. Fish sauce is a good substitute for those who can’t have shellfish. Hoisin sauce can be used for a stronger flavor.

  4. Mayonnaise – Adds a creamy texture and richness to the sauce. Whisk well to avoid clumping.

  5. Granulated sugar – Balances out the flavors and adds a touch of sweetness.

  6. Soy sauce – Adds a salty depth of flavor. Check if oyster sauce contains soy sauce, or swap it out with gluten-free options like coconut aminos or tamari. Coconut aminos are sweeter, so you may not need as much sugar.

  7. Garlic powder – Gives a subtle aroma and flavor. Feel free to add more or less depending on your preference for garlic flavor.


  1. Grab yourself a medium mixing bowl. You’ll want to combine all the ingredients in here – 2 tablespoons of ketchup, 1 and a half tablespoons of Worcestershire sauce, 1 tablespoon of Oyster sauce, 1 tablespoon of mayonnaise, 2 and a quarter teaspoons of granulated sugar, and 2 teaspoons of soy sauce. If you’re a garlic lover, you can add a pinch of garlic powder to taste.
  2. Once you’ve got all the ingredients in the bowl, get ready for a good arm workout. Whisk those ingredients together until everything is completely smooth. Trust me, this is worth it for the end result.
  3. Once you’ve got a smooth sauce, you can store it in the fridge to chill until you’re ready to use it. And the good news is, the flavor of the sauce will only improve as it chills.

And keep in mind that coconut aminos are sweet, so you might not need to add sugar.
