Kirkland Signature U-15 farm-raised white shrimp, sold previously frozen by the pound from Costco's fresh seafood case. The U-15 designation means fewer than 15 shrimp per pound, making these colossal-sized shrimp ideal for grilling, sauteing, or shrimp cocktail. These head-off, shell-on white shrimp are farm raised and arrive thawed for convenience, though they were originally frozen. Costco typically sources its farm-raised shrimp from India, Thailand, or Ecuador.

Raw shell-on shrimp offer superior flavor and texture compared to pre-cooked varieties, and the large U-15 size provides a meaty, satisfying bite. They can be peeled and deveined at home before cooking. Best prepared by grilling, pan-searing, deep frying, or boiling, and they pair well with cocktail sauce, garlic butter, or light seasoning.
