Pollock is a mild, slightly sweet white fish with a delicate flavor and firm texture. It’s one of the most widely eaten fish in the world, though many people don’t realize it because pollock is the primary ingredient in imitation crab and the fish in most fast-food fish sandwiches. If you’ve ever had a fish stick, you’ve almost certainly had pollock.
Taste and Texture
Pollock has a clean, subtly sweet flavor that’s milder than cod and less “fishy” than haddock. The flesh is firm enough to hold together during cooking but lighter and more tender than cod, making it easy to flake apart with a fork. Raw pollock flesh is off-white to slightly gray, turning opaque white when cooked. Atlantic pollock tends to have slightly darker flesh and a marginally stronger flavor than its Pacific (Alaska) counterpart, but both are firmly in the “mild white fish” category.
The texture is what makes pollock so versatile. It’s moist without being mushy, with a fine flake that works well breaded, baked, pan-seared, or poached. People who dislike strong-tasting seafood tend to enjoy pollock because it takes on the flavor of whatever seasoning or sauce you pair it with.
How Pollock Compares to Cod and Haddock
Pollock belongs to the cod family, and the two fish are often used interchangeably in recipes. The main differences come down to texture and price. Cod has thicker, denser fillets with large flakes, while pollock is thinner, more tender, and slightly less rich. Haddock falls somewhere in between, with a bit more flavor than pollock but a similar flake size.
Pollock is consistently cheaper than both cod and haddock, which is one reason the commercial fishing industry gravitates toward it. If a recipe calls for any mild white fish, pollock will work. You’ll notice the biggest difference in dishes where the fish is the star (like a simple pan-sear with lemon), where cod’s meatier texture stands out. In tacos, fish and chips, chowders, or anything breaded, most people can’t tell them apart.
Nutrition and Mercury
A 3-ounce cooked serving of Alaska pollock delivers 3.1 micrograms of vitamin B12, which exceeds the daily recommended amount for most adults, along with 38 micrograms of selenium, covering roughly 70% of a day’s needs. It’s a lean protein source with minimal saturated fat.
Pollock also provides omega-3 fatty acids, though less than fattier fish like salmon or mackerel. Per 100 grams of fish, pollock contains about 100 milligrams of EPA and 400 milligrams of DHA, the two omega-3s linked to heart and brain health. That translates to roughly 425 milligrams combined in a standard 3-ounce serving.
Mercury is often a concern with seafood, and pollock ranks among the lowest-mercury fish you can buy. Its average mercury concentration is 0.031 parts per million, which is lower than cod (0.111 ppm), haddock (0.055 ppm), and even whiting (0.051 ppm). Only a handful of commonly eaten fish, like tilapia, test lower. This makes pollock a safe choice for frequent consumption, including for pregnant women and young children.
How Pollock Is Used Commercially
Pollock is the backbone of the processed seafood industry. About 250,000 metric tons of Alaska pollock are turned into surimi each year. Surimi is the paste used to make imitation crab (sometimes labeled “krab”), which shows up in California rolls, seafood salads, and crab rangoon. The fish’s mild flavor and firm texture make it ideal for this purpose because it blends seamlessly with added flavoring.
The Alaska pollock fishery is the largest in the United States and the largest certified fishery in the Marine Stewardship Council program, with over 1.3 million metric tons harvested annually. It was first MSC-certified in 2005 and has been recertified multiple times since. Pollock reproduce quickly, reaching maturity at around four years, which helps the population stay healthy under heavy fishing pressure.
Best Ways to Cook Pollock
Because pollock fillets are thinner and more delicate than cod, they cook fast and benefit from methods that don’t require a lot of handling. The fish is done when the flesh turns opaque throughout.
- Pan-searing: Dredge fillets lightly in seasoned flour and cook on high heat for about 2 minutes per side. The flour creates a golden crust while keeping the inside moist. Sautéed onions and garlic make a simple base.
- Poaching: Bring water to a simmer, add the fillets, cover, and cook for 4 to 5 minutes if frozen, or about 2 minutes if thawed. Let the fish rest in the water for 5 minutes after turning off the heat. This is the gentlest method and keeps the fish extremely tender.
- Baking: Season fillets with spices like coriander, salt, and pepper, then bake until opaque. Pollock works well in foil packets with vegetables, where it steams in its own moisture.
- Breading and frying: Pollock’s mild flavor and firm-enough texture make it a natural choice for fish and chips, fish tacos, or fish sandwiches. Air frying gives similar results with less oil.
The one method to approach carefully is grilling. Pollock fillets are thin enough that they can fall apart on grill grates. If you want to grill it, use a fish basket or grill mat, or choose thicker fillets.
Two Species, One Name
When you see “pollock” at the store, it’s almost always Alaska pollock (also called walleye pollock), which lives in the Bering Sea and Gulf of Alaska. Atlantic pollock is a separate species found in the North Atlantic. Both are members of the cod family, but Alaska pollock dominates the market due to the sheer scale of the fishery.
Alaska pollock are speckled fish with black and yellow spots along their bodies, growing up to 3 feet long. Atlantic pollock have a greenish hue and slightly darker flesh. In practical terms, the flavor difference between the two is small enough that most recipes treat them interchangeably. If you’re buying frozen fillets or fish sticks from a major brand, you’re getting Alaska pollock.
