Costco's Seasoned Carne Asada Beef Flap Meat is a pre-marinated, ready-to-cook cut of USDA Choice beef sirloin flap (bavette), available from the service deli and sold by the pound. The beef is generously seasoned with a blend of traditional Mexican-style spices, including onion, garlic, citrus, and chili pepper, giving it a savory, well-rounded flavor with a hint of heat.

Beef flap meat (sirloin flap) is a well-marbled, tender cut with excellent flavor and texture, making it the traditional choice for authentic carne asada. Because it is pre-seasoned, no additional marinating or prep is needed—simply take it directly to the grill. Cook over high heat for approximately 8 to 15 minutes, then slice thin against the grain for best results.

This seasoned carne asada is ideal for tacos, burritos, fajitas, and rice bowls, and pairs perfectly with fresh tortillas, pico de gallo, guacamole, and grilled vegetables.
