[1][2] Like tonkatsu, chicken katsu is generally served with tonkatsu sauce (とんかつソース), a thick Japanese vegetarian pureed fruit-based brown sauce, along with rice or miso soup as part of a two- or three-item set meal, or as dinner with rice and vegetables.
In Hawaii, chicken katsu is more popular than tonkatsu and substitutes for it in dishes such as katsukarē and katsudon.
[3] In a plate lunch, chicken katsu is generally served on a bed of shredded cabbage,[4] with a well-seasoned ketchup similar to cocktail sauce.
[5][6] In the United Kingdom, the word "katsu" has become synonymous with Japanese curries as a whole, owing to the rapid rise in popularity of chicken katsu curry.
[7] Katsu (カツ) is a shortened form of katsuretsu (カツレツ), the Japanese transliteration of the English word "cutlet".
