Costco's USDA Choice Beef Outside Skirt Steak is sold by the full case, priced per pound, making it well-suited for commercial kitchens, caterers, and bulk buyers. The outside skirt is cut from the Short Plate primal, located beneath the rib section, and is also widely known as arrachera, fajita steak, or fajita meat (IMPS/NAMP 121C). USDA Choice designation indicates high-quality beef with solid marbling — graded above Select and just below Prime — delivering a consistent, satisfying eating experience.

The outside skirt is celebrated for its bold, robust beef flavor and coarse, satisfying texture. It responds exceptionally well to marinades and is the classic cut of choice for fajitas, tacos, and carne asada. For best results, cook over high direct heat on a grill, cast iron skillet, or under a broiler. Sear quickly on both sides and always slice firmly against the grain to maximize tenderness and ensure the best mouthfeel.
