Skirt steak is a cut of beef steak from the plate. It is long, flat, and prized for its flavor rather than tenderness. It is not to be confused with flank steak, a generally similar adjacent cut nearer the animal's rear quarter.
Skirt steak is the cut of choice for making fajitas, arrachera, Chinese stir-fry, churrasco, and in Cornish pasties.
To minimize toughness and add flavor, skirt steaks are often marinated before grilling, pan-seared very quickly or cooked very slowly, typically braised. They are typically sliced against the grain before serving to maximize tenderness.
