Beef chow fun is a Cantonese dish prepared by stir-frying previously marinated beef slices together with flat, wide rice noodles (hor fun), and bean sprouts. Because of the preparation method, beef chow fun is a true measure of any accomplished Cantonese chef.

Specifically, it is necessary to get two things right: wok hei — the cooking technique of stir-frying the ingredients at high heat which imparts them with a special umami flavor; and pow wok — a way of quickly tossing the ingredients without the use of a spatula, which prevents sticking and does not break the delicate rice noodles.

The origins of the dish are still unclear, but according to a folk tale, it was invented during World War II in Guangzhou. Today, this Cantonese stir-fry is typically served in yum cha restaurants and cha chaan teng – tea restaurants known for serving diverse and affordable meals.
