This USDA Prime top sirloin whole is a premium cut of beef sold vacuum-packed for freshness. The "cap off" designation indicates the flavorful sirloin cap (coulotte) has been removed, leaving the leaner portion of the top sirloin. This whole roast typically weighs between 6-15 pounds and is sold by the pound.
USDA Prime represents the highest grade of beef, featuring exceptional marbling that delivers superior tenderness and rich, beefy flavor. Customers describe this cut as having "the tenderness of a filet, the flavor of a ribeye." The vacuum packaging preserves quality and allows for extended refrigerator storage or freezing.
This versatile cut can be prepared as a whole roast for special occasions, broken down into individual steaks for grilling, or used for sous vide cooking. Popular preparation methods include reverse searing, grilling at high heat (500°F), smoking on pellet grills, or sous vide at 129-134°F followed by a high-heat sear to develop a flavorful crust. The lean profile makes it ideal for those seeking premium beef with less fat than ribeye while maintaining excellent flavor and tenderness.
