Kirkland Signature U-15 Farmed White Prawns are large, farm-raised Pacific white shrimp (Litopenaeus vannamei) sold fresh from previously frozen stock, priced per pound at the Costco seafood counter. The "U-15" designation means there are under 15 shrimp per pound, making these among the largest shrimp available and ideal for grilling, sautéing, steaming, or serving as an impressive centerpiece.

Farm-raised in controlled aquaculture environments, Vannamei white shrimp are prized for their mild, sweet flavor and firm, juicy texture. The prawns are typically sold shell-on and deveined, ready for a wide range of preparations including shrimp cocktail, pasta, stir-fry, and barbecue. Their large size holds up well to high-heat cooking methods and marinades.
