How Costco's Shrimp Program Has Evolved

Costco's commitment to sustainable seafood has significantly improved over the past decade. According to the Monterey Bay Aquarium Seafood Watch report, Costco transitioned to 100% wild-caught or responsibly farmed shrimp across all products by 2020. Their current garlic butter shrimp uses Pacific white shrimp (Litopenaeus vannamei) sourced from fisheries that meet Marine Stewardship Council standards—a notable improvement from their earlier product lines that included unspecified shrimp sources.

Perfect Cooking Method Every Time

Professional chefs recommend these precise steps for optimal results with Costco's garlic butter shrimp:

1. Preheat skillet over medium-high heat with 1 tsp olive oil
2. Add frozen shrimp in single layer (no need to thaw)
3. Cook 3-4 minutes per side until opaque and slightly caramelized
4. Remove from heat immediately to prevent overcooking
5. Add fresh lemon juice and additional parsley

Avoid common mistakes: never boil these shrimp (makes them rubbery) and don't overcrowd the pan (prevents proper searing). The butter and garlic coating means you don't need additional seasoning—just a squeeze of fresh lemon enhances the natural flavors.

When This Product Shines (And When to Skip It)

Understanding the specific scenarios where this product delivers maximum value helps optimize your shopping decisions:

• Best for: Weeknight dinners when time is limited, entertaining guests with minimal preparation, or as a protein boost for salads and pasta dishes
• Consider alternatives when: You need specific dietary modifications (like dairy-free), want larger shrimp sizes (Costco's version is medium), or require precise control over sodium content
• Storage note: Keep frozen until ready to use; once cooked, consume within 2 days or freeze for up to 2 months
