Halibut

Halibut: Nutrition, History and Cooking Guide

Halibut is the largest of the flatfish — Atlantic halibut (Hippoglossus hippoglossus) and Pacific halibut (H. stenolepis) are among the largest bony fish in the ocean, with specimens recorded over 300 kg though commercial fish are typically much smaller. The name derives from the Old English "halybutte" — the holy flatfish — because it was traditionally eaten on holy days. Historically abundant across the North Atlantic, Atlantic halibut was severely overfished during the nineteenth and twentieth centuries and remains depleted. Pacific halibut from Alaskan and Canadian fisheries is managed under one of the world's most rigorous fisheries management systems and is a recommended sustainable choice. The firm, snow-white, sweet flesh of halibut is one of the finest in the sea and commands premium prices in quality restaurants on both sides of the Atlantic.

Nutritional Value of Halibut

Halibut provides 116 kcal and 20.5 g of protein per 100 g, with 2.9 g of fat — lean for a large, premium fish. It provides complete protein, omega-3 fatty acids, niacin, B6, B12, selenium, magnesium, and phosphorus. The selenium content of halibut is notably high.

Health Benefits of Halibut

Halibut is a lean, nutritionally rich fish with exceptional selenium content — a meaningful single source of this essential mineral. Omega-3 supports cardiovascular and anti-inflammatory health. Magnesium supports muscle and nervous system function. B12 supports neurological health. Pacific halibut from certified sustainable fisheries offers outstanding nutrition with good environmental credentials.

How to Select and Store Halibut

Fresh halibut should be very white, extremely firm — firmer than cod or haddock — and have a clean, sweet sea smell. It bruises easily and should be handled gently. Refrigerate for up to two days; freeze for up to three months. Sold as steaks across the bone or as thick fillets.

How to Cook Halibut

Halibut's density means it needs slightly more cooking time than most fish. Pan-sear in butter and oil over medium-high heat for three to four minutes per side, developing a golden crust. Rest for two minutes. Do not overcook — the flesh goes from silky to dry very quickly past the point of just-opaque. Poaching in a court bouillon of white wine and aromatics produces clean, elegant results. Halibut suits beurre blanc, brown butter and capers, salsa verde, or a simple herb oil — its quality deserves simple, respectful accompaniments.
