Pork Cutlet Rice Bowl — Tonkatsu Simmered with Egg
This katsudon recipe fries a panko-crusted pork cutlet until golden, then simmers it with onion and beaten egg in a sweet-savoury dashi broth and slides the whole lot over steaming rice. It is the donburi that turns leftover-style tonkatsu into a complete one-bowl dinner — unlike gyudon, which is thin beef and onions with no egg, and unlike oyakodon, which uses chicken and egg with no breaded cutlet at all. One serving is about 460 g.
Katsudon was born in the early 20th century, when Japanese cooks began serving the Western-style breaded pork cutlet — tonkatsu, itself a Meiji-era adaptation of European cutlets — simmered with egg in dashi and ladled over rice. The dish is often credited to a Tokyo soba shop, Kawakami, in 1918, though the exact origin is disputed; what is certain is that by the 1920s it had become a staple of cheap, filling student and worker meals. The name joins katsu (cutlet) with don (bowl).
Pairs well with: Miso soup, pickled ginger and a pot of green tea

Real katsudon simmers the fried cutlet only briefly in dashi with onion, then sets the egg soft and glossy — never a firm omelette, and never a plain cutlet on plain rice.
Execution Methodology & Culinary Technique
Prep Stage: Pound the Cutlets, Start the Rice
20 Mins • Knife Work & Rice
Get the rice cooking first — it takes longer than the cutlets. While it steams, pound each pork cutlet to an even 1.5 cm thickness, then set up the breading line: flour, beaten egg, panko, in that order. Slice the onion, beat the four simmering eggs lightly in a jug, and measure the dashi, soy sauce, mirin and sugar into one jug so the broth comes together in seconds.
Maestro Tip: Even thickness is the whole game: a cutlet that is thick on one side and thin on the other fries unevenly and dries out at the edges.
15 Mins Simmer, about 100°C (212°F), then rest off the heat
Rinse the rice until the water runs clear, then cook it with 360 ml of water: bring to a boil, cover, turn the heat to its lowest setting and cook for 12 minutes. Take it off the heat and leave it covered for 10 minutes — do not lift the lid. Fluff with a fork and keep warm.
Resist lifting the lid during the rest; the trapped steam finishes the grains.
Done when: The rice is fluffy, each grain separate, with no wet layer at the bottom.
12 Mins 170°C (340°F)
Coat each cutlet in flour, shake off the excess, dip in beaten egg, then press firmly into the panko so the crumbs stick. Fry two at a time in the hot oil for 3–4 minutes per side until deep gold and crisp. Drain on a wire rack, then slice each cutlet into strips about 2 cm wide — keep the strips in their original shape so they lift onto the rice in one neat row.
Press the panko on with your palm; crumbs that are only dusted on fall off in the oil.
Done when: The crust is deep gold and crisp, the pork inside is just cooked through to 71°C (160°F), and the juices run clear.
5 Mins Gentle simmer, about 95°C (203°F)
Put the dashi, soy sauce, mirin and sugar in a wide pan and bring to a gentle simmer. Add the sliced onion and simmer for 4–5 minutes until it is soft and translucent.
A wide pan matters: the onion must sit in the broth, not pile up in a heap.
Done when: The onion is limp, translucent and sweet to taste.
4 Mins Gentle simmer, about 95°C (203°F)
Lay the sliced cutlet strips over the onion in their neat rows, then pour the beaten eggs slowly over the top, in a thin spiral so the egg settles between the strips. Cover and cook for 1–2 minutes only — the egg should just set, soft and glossy, not firm like an omelette.
Take the pan off the heat while the egg still looks slightly wet; it finishes setting in the residual heat.
Done when: The egg is softly set and glossy, the cutlet strips are still visible through it, and the crust underneath stays crisp.
2 Mins Serve hot; pork cooked to 71°C (160°F)
Spoon hot rice into deep bowls. Tilt the pan and slide the cutlet-and-egg blanket onto the rice in one piece, letting the broth trickle over the top. Scatter with scallions and serve at once.
Slide, do not spoon: spooning breaks the egg blanket and the cutlet strips apart.
Done when: The bowl is hot, the egg is soft and glossy, and the rice below is moist with sweet-savoury broth.
Finishing Touches & Plating
Eat katsudon hot, straight away — the contrast of the crisp cutlet, the soft just-set egg and the steaming rice is the whole point, and it fades within minutes.

Vitamins & minerals: Vitamin B1 (thiamine) and B6 (pork), vitamin B12 (pork, egg), selenium (egg, pork), niacin (pork).
High in Protein
About 53 g of protein per serving from pork and egg, which helps keep you full long after a fast, light-tasting bowl.
Thiamine and B12
Pork is one of the richest natural sources of vitamin B1 (thiamine), and pork and egg together supply vitamin B12, which supports normal energy metabolism.
Comforting One-Bowl Meal
The soft egg, warm broth and steamed rice make this one of the easiest substantial meals to eat when you want something comforting.
Food Pairings
To optimize nutrient absorption and elevate the sensory depth, pair with these authentic accompaniments:
Soups
Miso Soup
A small bowl of miso soup is the classic katsudon partner — its salty, savoury warmth balances the sweet broth of the rice bowl.
Sides
Shredded Cabbage Salad
Crisp shredded cabbage with a little tonkatsu sauce adds freshness and crunch against the rich fried cutlet.
Vegetables
Pickled Ginger
Sharp, bright pickled ginger cuts through the rich fried pork and refreshes the palate between bites.
Drinks
Iced Green Tea
Cold, unsweetened green tea cleanses the palate and keeps the rich pork bowl from feeling heavy.
Full Menus
As a Teishoku Set
Serve the bowl with miso soup and shredded cabbage, the way Japanese set-meal restaurants do — fast, filling and balanced.
Complete menu
Serve the bowl with miso soup and shredded cabbage, with iced green tea to drink.
Digestive Guardrails
To prevent digestive distress, sluggishness, or palate clash, avoid pairing the dish with these elements:
Overcooking the Egg
Egg left on the heat until firm turns rubbery and dries out the cutlet underneath — take the pan off while the egg still looks slightly wet. This is general guidance, not medical advice.
Letting the Bowl Sit
Katsudon softens as it sits: the steam from the rice makes the panko crust soggy within minutes, so serve it the moment it is assembled.
