Fresh Wild Atlantic Halibut Fillet is a premium flatfish sold by the pound at Costco warehouse locations. Atlantic halibut (Hippoglossus hippoglossus) is the largest species of flatfish in the world, prized for its mild, slightly sweet flavor and firm, dense white flesh that flakes beautifully when cooked.

These fillets arrive fresh, never frozen, offering the clean taste of wild-caught fish directly from cold Atlantic waters. The thick, meaty texture holds up well to a variety of cooking methods. Halibut is well-suited for grilling, baking, broiling, pan-searing, or poaching. Its low fat content means it benefits from added moisture or fat during cooking — butter, olive oil, or a wine-based poaching liquid all complement it well. A general guideline is to cook for 8–10 minutes per inch of thickness at 400°F until the flesh turns opaque and flakes easily with a fork.

Wild Atlantic halibut is an excellent source of lean protein, B vitamins (particularly B12 and niacin), selenium, magnesium, and phosphorus. It also provides omega-3 fatty acids, which support cardiovascular and cognitive health. Halibut is naturally low in calories and saturated fat, making it a nutritious addition to a balanced diet.
