Ling Cod
Lingcod (Ophiodon elongatus) is a large predatory fish found along the Pacific coast from Alaska to Baja California. Despite its name, it isn't a true cod at all, it belongs to the greenling family. Its flesh is firm, lean, and mild, with large flakes similar to halibut, and it occasionally has a naturally blue-green tint that turns white when cooked. It's prized in West Coast markets but less familiar elsewhere, so it's often sold simply as "ling cod" or "lingcod fillet."
Varieties
Lingcod is sometimes confused with Pacific cod or true cod because of the shared name, but they are different species with lingcod having a firmer texture and occasionally blue-tinted raw flesh. Some markets also label rock greenling or kelp greenling as lingcod, though these are smaller, related species with a milder flavor.
Buying tips
Look for fillets that are translucent to pale pinkish-white (or naturally blue-tinged) with a moist, slightly firm surface and no strong fishy odor, which should smell like the sea rather than ammonia. Skin-on fillets keep the flesh from breaking apart during cooking and are easier to spot for freshness at the fish counter.
Substitutes
Pacific cod (true cod) — 1:1
Milder and slightly softer texture than lingcod, but the closest everyday substitute in most recipes.
Halibut — 1:1
Firmer and leaner; holds up well to grilling or pan-searing where lingcod would be used the same way.
Rockfish or red snapper — 1:1
Slightly more delicate flake and a touch sweeter, works well in tacos, chowders, or breaded preparations.
Haddock — 1:1
Softer texture than lingcod but a good stand-in for baked or fried fillet recipes.
Sablefish (black cod) — 0.75:1
Much higher fat content and richer flavor, so use slightly less to avoid overpowering a dish built around lean fish.
Storage
Fresh lingcod fillets should be used within one to two days of purchase. Keep them in the coldest part of the refrigerator, ideally set directly on ice in a shallow dish covered loosely with plastic. For longer storage, wrap tightly in plastic then foil and freeze for up to three months; thaw overnight in the refrigerator rather than at room temperature to keep the texture intact.
How to use
Lingcod's firm, large-flake texture holds together well for pan-searing, grilling, baking, and deep-frying, making it a common choice for fish and chips on the West Coast. It also works in chowders and ceviche since it stays firm rather than falling apart. Cook to an internal temperature of 130 to 135 degrees Fahrenheit for a moist result, since it dries out quickly past that point.
What it pairs with
Pairs well with brown butter, capers, lemon, and fresh herbs like dill or tarragon, as well as with light beer batter for frying. A crisp white wine such as sauvignon blanc or a dry Pacific Northwest pinot gris complements its mild flavor.
Nutrition
Lingcod is very lean and high in protein, with roughly 20 grams of protein and under 2 grams of fat per 4-ounce cooked portion. It's also a good source of selenium and vitamin B12.
FAQ
Is lingcod actually a type of cod?
No, lingcod belongs to the greenling family, not the true cod family. The name comes from early fishermen who thought its shape and flavor resembled cod.
Why is some lingcod flesh blue or green?
A natural pigment called biliverdin, tied to the fish's diet, can tint the raw flesh blue-green. It's harmless and disappears completely once the fish is cooked.
Can lingcod be eaten raw, like for sushi?
It's not typically used raw because of its texture and the risk of parasites common in wild-caught groundfish; it's almost always sold and prepared cooked.
What's the best way to keep lingcod from drying out?
Cook it just to 130-135°F internal temperature and pull it from heat slightly early, since carryover cooking will finish it and its lean flesh dries out quickly past that point.
