Wild-caught brown shrimp sold by the pound at the Costco seafood counter. The "U-15" size designation means fewer than 15 shrimp per pound, placing these in the extra-jumbo to colossal size category — among the largest shrimp commercially available.

Brown shrimp are wild-harvested from Gulf Coast and Atlantic waters and are prized for their firm texture and distinctly robust, briny-sweet flavor with mild mineral notes. Previously frozen at sea immediately after harvest to preserve peak freshness, then thawed for in-store sale. Shell-on format protects the delicate meat during transport and enhances flavor when used in stocks, broths, and shell-on preparations.

These oversized shrimp are well suited for high-heat cooking methods including grilling, pan-searing, and broiling, as their size holds up without overcooking. They are equally versatile for shrimp cocktail, seafood boils, pasta dishes, and stir-fries.
