Pepper steak (Chinese: 青椒牛 or 青椒牛肉, pinyin: qīngjiāo niúròu; Japanese: 青椒肉絲, chinjao ro su; also called green pepper steak) is a stir-fried Chinese American dish consisting of sliced beef steak (often flank, sirloin, or round) cooked with sliced green and/or red bell peppers and other seasonings such as soy sauce and ginger, and usually thickened with cornstarch. Sliced onions and bean sprouts are also frequent additions to the recipe.
Evidence for the dish's existence in the United States dates from at least 1948.[1] The dish originated from Fujian cuisine, where it was known as qīngjiāo ròusī (青椒炒肉絲)[1]. In the original dish the meat that was used was pork and the seasonings were relatively light compared to pepper steak.
A similar dish, called chin-jao rōsu (青椒牛肉) is found in Japanese Chinese cuisine.
