Extra-jumbo wild-caught Gulf prawns sold fresh by the pound from Costco's seafood counter (previously frozen, thawed for convenience). The "U-15" grade designation indicates fewer than 15 shrimp per pound, making these among the largest shrimp available — a colossal size prized by both home cooks and professional chefs.

Sourced from the Gulf of Mexico, these wild prawns are known for their sweet, briny flavor and firm texture that hold up beautifully to high-heat cooking methods. Each prawn features a rich, meaty bite that farm-raised varieties rarely match. The shells are typically intact, which adds flavor when grilling or boiling and can be peeled prior to other preparations.

These jumbo prawns are ideal for grilling skewers, steaming whole, boiling for a classic shrimp boil, pan-searing with garlic and butter, or serving chilled in an elegant shrimp cocktail. Because they are sold individually by weight, shoppers can purchase exactly the quantity they need. Kirkland Signature branding may appear depending on the location and lot.
