Sauce Katsudon — Japanese Pork Cutlet Rice Bowl with Worcestershire Sauce
Sauce katsudon (ソースカツ丼) is a regional Japanese rice bowl that surprises a lot of people: instead of the familiar egg-and-onion katsudon, here a crispy pork cutlet is dunked in a sweet-savory Worcestershire-based sauce and laid over rice and shredded cabbage. No egg, no dashi broth — just glossy, sauce-soaked tonkatsu on a bed of fluffy rice. It’s the pride of places like Fukui, Komagane, and Aizu, and once you try it, you’ll understand the devotion.
The magic is in the sauce — a quick simmer of Worcestershire sauce, ketchup, mirin, and sugar that turns tangy and glossy. You fry the cutlet, dip the whole thing in the warm sauce so it soaks in, then slice and pile it on rice. Here’s exactly how I made it.

What is Sauce Katsudon?
Katsudon (カツ丼) means “cutlet rice bowl.” The version most people know is tamago katsudon — pork cutlet simmered with onion and egg in a dashi-soy broth. Sauce katsudon is the other great tradition: the cutlet is dipped in a Worcestershire-style sweet sauce (sōsu) instead, and served over rice with shredded cabbage rather than egg. It’s a beloved regional dish in Fukui Prefecture, Komagane in Nagano, and the Aizu region of Fukushima, each with slightly different sauces.

Ingredients (Serves 2)
| Ingredient | Amount | Notes |
|---|---|---|
| Pork fillet / tenderloin (hire) | about 200 g per person | Leaner and more tender than loin; loin works too |
| Salt and pepper | To taste | |
| Cake flour | 2 tbsp | For breading |
| Egg | 1 | Beaten, for breading |
| Panko breadcrumbs | As needed | |
| Oil | For frying | |
| Cabbage | 100 g | Finely shredded |
| Cooked rice | 2 bowls |
For the sauce:
| Ingredient | Amount |
|---|---|
| Worcestershire sauce | 100 ml |
| Mirin | 2 tbsp |
| Ketchup | 1 tbsp |
| Sugar | 1 tsp |
The signature flavor comes from Bull-Dog Worcestershire sauce rounded out with Japanese mirin. For the cutlet, a generous coat of Japanese panko breadcrumbs gives the crunch, and it all goes over good Japanese short-grain rice.
How to Make Sauce Katsudon
Step 1: Make the Sauce
Combine the Worcestershire sauce, mirin, ketchup, and sugar in a small saucepan. Bring to a boil over medium heat, then transfer to a shallow dish or tray wide enough to dip a cutlet.
Step 2: Shred the Cabbage
Finely shred the cabbage. I use a Japanese cabbage peeler — the hugely popular Cabepi Max — which shaves the cabbage into ultra-fine, fluffy strands you simply can’t get with a knife. It’s the secret to that light, airy pile of cabbage you see at Japanese tonkatsu restaurants. Soak the shredded cabbage in cold water briefly for extra crispness, then drain well.
SaveStep 3: Bread and Fry the Cutlets
For a full step-by-step on breading and deep-frying a pork cutlet — including how to score the meat, set up a clean flour-egg-panko station, and get the crispiest crust — see my tonkatsu recipe. That recipe uses pork loin; here I used pork fillet (hire) for a leaner, extra-tender cutlet, but the breading and frying are exactly the same. Here’s the short version:
Score the edges of the pork to stop it curling, season both sides with salt and pepper, then coat in flour, beaten egg, and panko in that order. Heat oil in a deep frying pot to 180°C (356°F) — check it with a deep-fry thermometer — and fry the cutlets for about 4 minutes until deep golden and crisp.
Drain the fried cutlets on a wire rack so the coating stays crisp.
Step 4: Build the Bowls
Scoop hot rice into each donburi bowl, then top with a bed of the shredded cabbage.
Step 5: Dip the Cutlets in Sauce
Dip each fried cutlet into the warm sauce, turning to coat both sides so it soaks in.
Step 6: Slice and Serve
Transfer the sauced cutlets to a cutting board and slice into strips. Lay the pieces over the cabbage, drizzle with a little extra sauce, and sprinkle with sesame seeds. Serve immediately.
Tips and Variations
- Dip, don’t drown. A quick dip soaks the coating with flavor while keeping some crunch — don’t let the cutlet sit and go soggy.
- Keep the sauce warm. Warm sauce clings and absorbs better than cold.
- Adjust the sweetness. More sugar or ketchup for a sweeter, milder sauce; less for a sharper, more Worcestershire-forward one.
- Use a store-bought cutlet. In a hurry, a ready-made or leftover tonkatsu works — just reheat, dip, and serve.
What to Serve It With
Sauce katsudon is a hearty one-bowl meal, but a few sides round it out:
- Miso soup for a classic set, as pictured.
- A crisp, cold side like tataki ume kyuri to balance the richness.
- Extra shredded cabbage on the side — it cuts the fried richness perfectly.
Storing
Sauce katsudon is best eaten fresh, while the cutlet still has some crunch. If you have leftover fried cutlets, store them separately from the rice and sauce, and reheat in a toaster oven or air fryer before dipping — this keeps the coating from going soggy. The sauce keeps in the fridge for a week and is great on other fried foods too.
Frequently Asked Questions
What’s the difference between sauce katsudon and regular katsudon?
The familiar katsudon simmers the fried cutlet with onion in a dashi-and-egg mixture, so it arrives soft and soupy. Sauce katsudon skips the egg and dashi entirely: the cutlet is dipped in a Worcestershire-based sauce and laid straight onto rice, so it stays crisp. They’re genuinely different dishes.
Where is sauce katsudon from?
It’s a regional specialty in several parts of Japan, most famously Fukui, but also Aizu in Fukushima, Komagane in Nagano, and Okayama. The details differ by region — Fukui serves it on plain rice, while Aizu piles shredded cabbage between the rice and the cutlet, which is the style I make here.
Can you make katsudon without dashi?
This version needs none. The sauce is Worcestershire sauce, mirin, ketchup, and sugar — no dashi, no egg, no stock. If you don’t keep dashi in the house, sauce katsudon is the katsudon to make.
Can you reheat sauce katsudon?
The cutlet, yes; the assembled bowl, not really. Reheat leftover cutlets in a toaster oven or air fryer for a few minutes to bring the panko back to crisp, then dip in warmed sauce and serve over fresh rice. Microwaving turns the breading soft.
Can I use chicken instead of pork?
Yes. A chicken breast or thigh, pounded thin and breaded the same way, works well with this sauce — it just isn’t katsudon at that point. Pork tenderloin is the traditional cut because it stays tender and lean under the breading.
