Costco's in-store marinated boneless pork loin is a pre-seasoned, ready-to-cook cut prepared by the meat department and sold by the pound. The boneless pork loin is trimmed and marinated in-house, making it a convenient option for grilling, roasting, or slow cooking without additional prep.

Boneless pork loin is a lean, versatile cut that benefits from marination to enhance tenderness and flavor. For best results, cook to an internal temperature of 145 degrees Fahrenheit. The cut works well on the grill at medium heat (around 375 degrees Fahrenheit), in the oven, or in a slow cooker. Leftover portions can be frozen while still marinated and thawed later for quick meal preparation.
