This 4-pound bag contains jumbo farm-raised white shrimp graded at U-20 count, meaning fewer than 20 shrimp per pound. The "U-20" designation indicates a generous, substantial size — ideal for grilling, sautéing, stir-frying, shrimp cocktails, and main-course presentations where a large, impressive shrimp is desired.

Pacific white shrimp (Litopenaeus vannamei), sometimes marketed as white tiger shrimp, are among the most widely farmed shrimp species in the world, prized for their mild, slightly sweet flavor and firm, meaty texture. Farm-raised production ensures a consistent, year-round supply with uniform sizing and quality. Costco typically sources farmed white shrimp from countries such as Ecuador, India, and Thailand, where aquaculture operations are closely regulated for quality and food safety.

This raw frozen shrimp is best thawed overnight in the refrigerator or under cold running water before cooking. White shrimp cook quickly — typically 2 to 3 minutes per side over medium-high heat — and are done when they turn pink and opaque. They are naturally gluten-free and high in lean protein, making them a versatile, nutritious seafood option for a wide range of recipes.
