What Is Katsu Curry?

Katsu is Japanese shorthand for katsuretsu, itself a borrowing of the English word cutlet, and it means exactly that: a piece of meat, pounded flat, coated in panko breadcrumbs and fried. The word says nothing about curry. A tonkatsu is a pork cutlet, chicken katsu a chicken one, and both are eaten across Japan with shredded cabbage and a Worcestershire style sauce, no curry in sight.

Katsu curry, katsu kare in Japan, is the marriage of that cutlet with Japanese curry sauce, a dish with its own history: curry reached Japan in the late nineteenth century via the British navy, was adopted by the Japanese military as ration food, and evolved into kare raisu, the mild, thick, faintly sweet curry over rice that is now among Japan's most eaten home dishes. Lay a fried cutlet over it and katsu curry was born.

So the British usage that calls the sauce itself katsu, katsu flavour crisps, katsu sauce jars with no cutlet in sight, is backwards: katsu is the crunchy part. Nobody enforces this at dinner, but now you know.

Wagamama's version, on UK menus since the nineties, is the dish most Britons mean by the words. The chicken katsu curry at £15.30: a butterflied chicken breast in panko, fried to a shattering crust, sliced and laid over sticky white rice, with the curry sauce poured across and a dressed side salad with pickles completing the plate.

The sauce is the signature, mild, golden with turmeric, built on curry spices rounded with coconut, closer to Japanese kare than to anything Indian, and gentle enough that the dish converts children and chilli avoiders daily. The crumb staying crisp under hot sauce is the engineering the kitchen is actually judged on, which is why the sauce goes over at the last moment and why delivery katsu is always a compromise.

The numbers deserve honesty: at 988 kcal it is one of the menu's biggest plates, the fried crumb, rice and sauce all pulling one direction. The pickles are not decoration; they are the palate's relief valve, and the dish eats better alternated with them.

Wagamama runs the format in several directions. The yasai katsu curry at £15.10 swaps chicken for panko fried sweet potato, aubergine and butternut squash, fully vegan and beloved beyond its target audience; at 1223 kcal it actually outweighs the chicken version, fried vegetables drinking more oil than breast meat.

The hot chicken katsu at £15.30 (est.) keeps the build and turns the chilli up, a firm medium rather than a dare. Beyond the katsu name, the same section runs the firecracker range for genuine heat and the raisukaree for a lighter, citrus coconut register, the three styles covering most curry moods between them.

Elsewhere on the menu the crumb travels: the ebi katsu at £9.20 shrinks the idea onto prawns, the katsu udon at £13.90 pours the sauce over noodles instead of rice, the kids menu runs junior versions with a choice of sauces, and the dessert list plays the joke straight with the banana katsu. The sauce even sells solo, a pot at £1.20 that this site's readers overwhelmingly pour on chips.

The confusion katsu causes in Britain comes from the word curry meaning Indian by default here. Katsu curry belongs to a different lineage entirely: Japanese curry came via the British navy's Anglo Indian rations, was industrialised into roux blocks, and grew mild, thick and sweet, comfort food rather than spice craft. It shares almost nothing with a korma beyond colour, korma being a Mughlai dish of nuts, cream and slow aromatics.

Texture is the practical difference: Japanese style sauce is smooth and gravy thick, clinging rather than pooling, engineered for rice and cutlets. Heat is the second: a standard katsu sauce sits below even a mild Indian restaurant curry, which is precisely why it onboards children and spice sceptics.

Fans wanting the next step have honest routes: wagamama's own firecracker for heat, a Japanese curry house's kare raisu for the homeland version, or the home recipe on this site's chicken katsu page, which builds the sauce from spices rather than blocks and explains the double fry that keeps crumb crisp under sauce.

As a dish, yes, with the confidence of the numbers: it is wagamama's most ordered plate across two decades because the contrast engineering, crisp crumb, soft rice, silky sauce, sharp pickle, genuinely works, and the mildness is a feature rather than a failing, the rare restaurant dish an entire mixed table can share without negotiation.

As a habit, order it knowingly: 988 kcal is a serious plate, the menu's lighter pages exist for the days between, and the yasai version is the rare vegan swap that is nobody's compromise. As a cultural artefact, enjoy the irony that Britain exported curry to Japan via the navy and reimported it a century later through a noodle chain, renamed the sauce after the cutlet, and made it a national comfort food twice over.

Start with the classic at £15.30, argue about the variants later, and keep the pickles in rotation. The curry menu page holds every price and number this article stands on.
