What is Katsu?

Katsu is a beloved dish in Japanese cuisine that has won hearts worldwide with its simplicity and delicious flavors. At its core, katsu refers to a breaded and deep-fried cutlet of meat. The word ‘katsu’ is a shortened form of ‘katsuretsu,’ which itself is a Japanese adaptation of the English word ‘cutlet.’ The magic of katsu lies in its crisp, golden-brown breadcrumb coating, achieved by coating the meat in flour, then egg, and then finally Panko breadcrumbs. We have recipes for Chicken Katsu and pork Tonkatsu, which both come out perfectly. The fried cutlets can also be part of more elaborate dishes such as Katsu Curry, Katsu Ramen, or Katsudon (rice bowls).
