Arctic Char
Arctic char (Salvelinus alpinus) is a cold-water fish related to both salmon and trout, with flesh that ranges from pale pink to deep orange-red depending on diet and origin. Its flavor sits between the two: milder and less oily than salmon, but richer than most trout, with a delicate, slightly sweet finish.
Varieties
Wild arctic char, caught mostly in Arctic and sub-Arctic waters of Canada, Alaska, and Scandinavia, tends to have firmer flesh and more variable color than farm-raised char, which is bred for a consistent orange-pink hue.
Buying tips
Look for firm, moist flesh that springs back when pressed and skin that's shiny rather than dull. Most arctic char sold in North America is farm-raised (often labeled sustainably farmed), which tends to be more consistent in size and fat content than wild-caught.
Substitutes
Salmon (farmed or wild) — 1:1 by weight
Salmon has a bolder, oilier flavor and firmer flesh, so reduce cook time slightly since char cooks faster and dries out sooner.
Steelhead trout — 1:1 by weight
Very close in color, fat content, and texture; often the best drop-in match for both raw and cooked preparations.
Rainbow trout — 1:1 by weight
Milder and leaner than char, with thinner fillets, so watch cook times closely to avoid overcooking.
Sockeye salmon — 1:1 by weight
Deeper red color and stronger flavor than char; a good match when you want a similar vivid color on the plate.
Storage
Keep fresh arctic char in its original wrapping or wrapped tightly in plastic, set on ice or in the coldest part of the refrigerator, and use within 1 to 2 days. Frozen fillets keep well for up to 6 months in a sealed vacuum bag; thaw overnight in the refrigerator, never at room temperature.
How to use
Cook arctic char the way you would salmon or trout: pan-seared skin-side down, roasted at 400°F for 10 to 12 minutes, grilled in a foil packet, or poached gently in broth. It also works well raw as sashimi or cured like gravlax, since its fat content is high enough to stay moist without oiling up like salmon.
What it pairs with
Pairs well with citrus, dill, capers, and brown butter, and with lighter sides like fennel, cucumber, or new potatoes that don't compete with its delicate flavor.
Nutrition
Arctic char is rich in omega-3 fatty acids and high-quality protein, with generally less fat than farmed salmon, making it a leaner option with a similar nutritional profile.
FAQ
Is arctic char healthier than salmon?
It's comparable, with slightly less fat and fewer calories than farmed salmon while still delivering strong omega-3 levels, making it a good middle ground between salmon and leaner white fish.
Can arctic char be eaten raw?
Yes, sushi-grade or previously frozen arctic char is commonly used raw in sashimi and crudo preparations because its fat content keeps it from tasting dry or fibrous.
Why does arctic char taste different from salmon?
Arctic char has a lower oil content than most salmon, giving it a cleaner, milder flavor with less of the pronounced fishy richness salmon can have.
Does the skin need to be removed before cooking?
No, the skin crisps up well when pan-seared and many cooks leave it on for texture; just score it lightly to prevent curling in the pan.
