Shanghai fried noodles (Chinese: 上海粗炒; pinyin: Shànghǎi Cūchǎo) is a dish made from Shanghai-style noodles, which can be found in most Chinese food markets. The more commonly known Japanese udon can be used as a substitute. The noodles are stir-fried with beef cutlets, bok choy, and onion. The dish is a staple of Shanghai cuisine, which is usually served at dumpling houses. Shanghai fried noodles have become known to western chefs, including the celebrity chef Emeril Lagasse.
