What is Katsudon?

Katsudon (カツ丼) is a traditional Japanese donburi (rice bowl) made with tonkatsu—a breaded and deep-fried pork cutlet—that is sliced and briefly simmered in a flavorful broth of dashi, soy sauce, mirin, sake, and onions, then finished with beaten eggs. The entire mixture is served over hot Japanese short-grain rice.

The word "Katsu" comes from tonkatsu (pork cutlet), while "Don" is short for donburi, meaning a rice bowl dish.

Preparing the Tonkatsu

Step 1: Season the Pork

Pat the pork chops dry.

Season both sides with:

  • Salt
  • Black pepper

Step 2: Bread the Pork

Coat each pork chop in:

  1. Flour
  2. Beaten egg
  3. Panko breadcrumbs

Press the breadcrumbs gently so they adhere well.

Step 3: Fry

Heat vegetable oil to 170–175°C (340–350°F).

Carefully fry each pork cutlet for 4–5 minutes per side, or until golden brown and cooked through.

Drain on a wire rack.

Allow the cutlets to rest for 2–3 minutes before slicing into strips.

Making the Katsudon Sauce

In a large skillet combine:

  • Dashi stock
  • Soy sauce
  • Mirin

  • Sugar

Bring to a gentle simmer.

Add the sliced onions.

Cook for 5–7 minutes until tender.

Cooking the Katsudon

Arrange the sliced pork cutlets over the simmering onions.

Pour the lightly beaten eggs evenly over the pork.

Cover with a lid.

Cook for 1–2 minutes, until the eggs are just set but still soft and silky.

Avoid overcooking, as the eggs should remain slightly creamy.

Preparing the Rice

Cook Japanese short-grain rice according to the package instructions or in a rice cooker.

Divide the hot rice evenly among four serving bowls.

Assembling the Katsudon

Carefully slide the pork, onions, eggs, and sauce over each bowl of rice.

  • Green onions
  • Mitsuba
  • Pickled red ginger
  • Shichimi togarashi
