Haddock vs. Halibut: What's the Difference?
By Aimie Carlson & Harlon Moss || Updated on March 4, 2024
Haddock and halibut are both popular seafood choices, with haddock being smaller and known for its lean, white flesh and mild flavor, while halibut, significantly larger, offers a firmer, denser texture and a sweet, rich taste.
Key Differences
Haddock is a saltwater fish primarily found in the North Atlantic Ocean. It is a key species in the fishing industry, especially in the northeastern United States and Canada, as well as in Europe. Halibut, on the other hand, is one of the largest flatfish species, inhabiting the cold waters of the North Pacific and North Atlantic oceans.
Haddock is smaller compared to halibut, typically weighing up to 5 pounds, and is distinguished by its dark lateral line and a black spot on each side of its body. Its flesh is lean, white, and flaky with a subtle sweetness, making it a favorite for frying, baking, and in seafood dishes like fish and chips. Halibut can grow to be quite large, with some individuals weighing over 500 pounds, though market-sized fish are usually between 10 to 50 pounds. The fish has a mild, sweet taste with a firm and dense texture, making it versatile for many cooking methods, including grilling, roasting, and pan-frying. Halibut's larger size and meaty texture often make it a more expensive option compared to haddock.
While both fish are valued for their taste and texture, their culinary uses differ due to their texture and flavor profiles. Haddock is often preferred for its delicate flavor in traditional fish dishes, whereas halibut's meaty texture makes it suitable for a wider range of recipes that require a firmer fish.
