Skirt steak is a long, flat cut of beef from the plate section of the cow. Its unique texture and flavor make it a favorite for many dishes, especially when grilled or used in tacos, fajitas, or stir-fries. The marbling and fat in skirt steak help it stay juicy and tender, especially when cooked quickly over high heat. The fact that it absorbs marinades so well really enhances its taste—so whether you're using a simple citrus-based marinade or something more complex with spices, skirt steak is a versatile choice.
