Premium USDA Prime beef loin top sirloin steak, boneless with cap removed, sold per pound under the Kirkland Signature brand. This is the highest quality grade of beef available, featuring exceptional marbling for superior tenderness and rich flavor. The top sirloin cut comes from the rear back portion of the animal and offers excellent steakhouse flavor at a more affordable price point compared to premium cuts like ribeye or strip steak.
This versatile cut is ideal for grilling, pan-searing, or sous vide cooking methods. The boneless cap-off preparation means the sirloin cap (also called picanha) has been removed, leaving a uniform, lean muscle that cooks evenly. Perfect for weeknight dinners or special occasions when grilled to medium-rare (129ยฐF internal temperature) and finished with high heat for a flavorful crust.
