Costco's Fresh Wild Haddock Fillet is sourced from wild-caught Atlantic haddock (Melanogrammus aeglefinus), a lean, mild white fish prized for its delicate flake and clean flavor. Sold fresh by the pound, these fillets are skinless and boneless, making them ready to cook with minimal prep.

Haddock is one of the most popular eating fish in the North Atlantic region, commonly used in fish and chips, baked dishes, chowders, and pan-seared preparations. Its low fat content and firm texture hold up well to broiling, baking, frying, poaching, and steaming. The mild flavor pairs easily with butter, lemon, herbs, breadcrumbs, and cream-based sauces.

As a lean source of high-quality protein, haddock is naturally low in calories and rich in B vitamins, selenium, and phosphorus. It is a good option for health-conscious diets. Fresh fish should be refrigerated and used within 1–2 days of purchase, or frozen promptly for longer storage.
