Katsudon (Pork Cutlet and Egg Rice Bowl)
Japan's ultimate comfort food — crispy tonkatsu pork cutlet simmered briefly in a dashi-soy-mirin sauce with egg, served over steamed rice. Pure weeknight satisfaction.
About This Recipe
Katsudon is one of Japan's most beloved donburi (rice bowl) dishes and a fixture of yoshoku — Western-influenced Japanese cooking. A pre-fried tonkatsu pork cutlet is briefly simmered in a sweet-savoury dashi sauce with sliced onion, then finished with egg poured over the top in the final 30 seconds. The egg barely sets — just curdled but still custardy — before the whole thing is turned out over hot steamed rice. The result is layers of texture and flavour: crispy breaded pork that softens slightly in the sauce, sweet-savoury onion, silky half-set egg, and fluffy rice that absorbs all the cooking juices. Katsudon is traditionally eaten before exams in Japan — 'katsu' is a homophone of the word meaning 'to win' or 'to overcome'.

Instructions
- 1
Prepare the tonkatsu
Score the fat edge of each pork chop with a knife (prevents curling). Pound gently to even thickness. Season with salt and pepper. Dust in flour, dip in beaten egg, then press firmly into panko breadcrumbs.

Fry the cutlets
Heat oil to 170°C in a deep pan. Fry cutlets for 4–5 minutes per side until deep golden brown and cooked through (72°C internal temperature). Drain on a wire rack. Cut into 2 cm slices — keep the cutlet together as a unit.

Make the katsudon
In a small (20cm) frying pan, combine dashi, soy, mirin and sugar. Bring to a simmer over medium heat. Add onion slices and simmer 3–4 minutes until softened.

Add the cutlet
Lay the sliced tonkatsu over the simmering onions. Pour beaten egg in a circular motion over the cutlet. Cover the pan immediately.

Set the egg
Cook covered for exactly 30–45 seconds. The egg should be just set on top but still custardy. Do not over-cook — the egg continues cooking from the residual heat when placed on rice.

Serve
Tip the whole contents of the pan over a bowl of hot rice. Garnish with spring onion.
Pro Tips
- →
The small pan size matters — you want the egg to pool around the cutlet and set evenly, not spread thin across a large surface.
- →
Remove from heat while the egg is still slightly underdone — it sets further on the hot rice.
- →
If you don't have dashi, use 200ml water + 1 tsp dashi powder (hondashi) as a shortcut.
Variations
- •
Chicken katsudon: substitute chicken breast for pork — equally delicious and slightly lighter.
- •
Oyakodon: omit the tonkatsu entirely — simmer chicken pieces with onion in the same sauce, add egg to finish. Japan's other iconic donburi.
- •
Cheese katsudon: place a slice of mild cheese on the cutlet before adding the egg.
Storage
Best eaten immediately. If prepping ahead, keep the fried tonkatsu and sauce components separate and assemble per serving.
History & Origin
Katsudon was created in the early 20th century, combining the newly popular tonkatsu (a yoshoku/Western-influenced dish) with the Japanese donburi tradition. The Waseda University area of Tokyo claims origin, and university culture spread the dish as affordable student food. Its name's association with 'katsu' (to win) made it traditional pre-exam meal.
Frequently Asked Questions
Can I use store-bought tonkatsu for katsudon?
Yes — supermarket or restaurant tonkatsu works perfectly. Heat it in the oven first to restore crispness, then proceed with the katsudon sauce and egg.
What if I don't have a small frying pan?
Make katsudon in two separate small pans simultaneously, or use a larger pan and serve two portions at once — the egg layer will be thinner.
