Premium USDA Prime beef top sirloin trimmed full case, sold by the pound. This is a whole top sirloin subprimal cut with the cap removed, offering excellent value for those who want to portion their own steaks or roasts. USDA Prime represents the highest grade of beef with abundant marbling throughout the meat, resulting in exceptional tenderness, juiciness, and flavor.
Top sirloin is a versatile cut from the rear back portion of the animal. While more affordable than ribeye or New York strip, it delivers outstanding quality and flavor. The trimmed designation means excess fat has been removed, providing a leaner cut that's ideal for grilling, broiling, or pan-searing. Full case packaging typically contains one large piece weighing approximately 16-20 pounds, allowing you to cut custom thickness steaks to your preference or prepare as a whole roast.
The Prime grade contains significantly more intramuscular fat (marbling) than Choice or Select grades, which translates to superior taste and texture. This cut benefits from dry-heat cooking methods and should be sliced against the grain after cooking to maximize tenderness. Ideal for home butchers or anyone with freezer space who wants restaurant-quality beef at wholesale pricing.
