Katsudon (Pork Cutlet and Egg Rice Bowl)

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'.

Ingredients

Serves 2

• 2pork loin chops (about 150g each), fat trimmed
• 30 gplain flour
• 1egg, beaten (for coating)
• 80 gpanko breadcrumbs
• 300 mlvegetable oil, for frying
• 1medium onion, thinly sliced
• Sauce
• 200 mldashi stock
• 3 tbspsoy sauce
• 3 tbspmirin
• 1 tbspcaster sugar
• 4eggs, lightly beaten (for the katsudon)
• 400 gcooked short-grain Japanese rice, hot
• 2 tbspthinly sliced spring onion, to garnish

Instructions

1. 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.

2. 2

   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.

3. 3

   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.

4. 4

   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.

5. 5

   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.

6. 6

   Serve

   Tip the whole contents of the pan over a bowl of hot rice. Garnish with spring onion.

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.
