Fresh pork loin back ribs, also known as baby back ribs, sold by weight per pound. These premium baby back ribs are known for their exceptional meatiness, typically weighing over three pounds per rack compared to standard two-pound racks found at other retailers. The ribs come with the membrane already removed from the bone side, saving preparation time and ensuring better flavor penetration during cooking.

Costco's baby back ribs are extra meaty with visible marbling, cut from the loin section of the pig near the backbone. Each rack contains tender, flavorful meat that's ideal for grilling, smoking, or pressure cooking. The ribs are minimally processed with no artificial ingredients, bone-in, and typically packaged as three pieces per tray.

These ribs are larger than average baby backs, which extends cooking time by approximately 30-45 minutes compared to standard-sized racks. The membrane removal and generous meat coverage make these ribs particularly well-suited for low-and-slow smoking methods, oven baking, or Instant Pot preparation. Popular brands carried by Costco include Swift Premium and Kirkland Signature. When properly cooked, these ribs achieve fall-off-the-bone tenderness with rich pork flavor.
