How Long to Cook Salmon

Preparation

How to Prepare Salmon Before Cooking

Atlantic salmon has fine, soft scales that are easy to remove from tail to head. Gut through the belly and remove the dark kidney line running along the spine — this is important as it gives a bitter flavor if left. Remove gills for whole fish. Rinse the cavity thoroughly under cold running water until it runs clear. For fillets: cut along the backbone in one smooth motion. Remove pin bones with tweezers — run a finger along the centerline of the fillet to locate them.

For steaks: cut across the body 2 to 3 cm thick with a sharp, heavy knife. For whole fish: score the thickest section (just behind the head) with 2 to 3 diagonal cuts per side to allow heat to penetrate evenly. Always cook skin-on — the skin holds the fillet together and is easy to remove after cooking.

Method

How to Cook Salmon Step by Step

1. Scale, gut, and rinse thoroughly. Remove pin bones from fillets with tweezers.
2. Cut to chosen form: fillets (skin-on), steaks, or whole.
3. Prepare court-bouillon: cold water, white wine or wine vinegar, dill, lemon slices, bay leaf, onion, carrot, and peppercorns.
4. Bring court-bouillon to a gentle simmer.
5. Lower salmon into the hot liquid carefully, skin-side down for fillets.
6. Maintain a gentle simmer — surface should barely tremble.
7. Cook: fillets/steaks 15 to 22 min; whole 2 to 3 kg 40 to 55 min.
8. Test: flesh turns from translucent to opaque throughout at the thickest point.
9. Remove carefully with a wide slotted spatula.
10. Salt after plating. The skin peels off cleanly with a thin spatula.

Doneness

How to Know When Salmon Is Done

Salmon is done when the flesh changes from translucent, bright orange to opaque throughout. The flesh should separate into large, moist flakes with gentle fork pressure at the thickest point. Modern preference often allows for a very slightly translucent center (which is safe at temperatures above 60°C), but for full food safety the center should be fully opaque. The high fat content means salmon stays moist even when fully cooked through — it is more forgiving than lean white fish.

Safety note: for full safety, ensure the flesh is fully opaque throughout with no translucent sections. The internal temperature must reach 63°C / 145°F at the thickest point. Pregnant women and vulnerable individuals should always cook to full opacity.

Seasoning

Best Seasonings for Salmon

Court-bouillon with white wine, dill, and lemon is the classic approach. Dill sauce, hollandaise, cream-dill sauce, lemon-caper butter, and béarnaise are all excellent accompaniments. Scandinavian gravlax style — cured with salt, sugar, and dill — is not cooked but demonstrates salmon’s natural versatility. The cooking broth, once strained and reduced, makes an outstanding base for cream sauces.

Avoid this

Common Mistakes

• Not removing pin bones — easily found by running a finger along the fillet centerline.
• Boiling hard — breaks the flesh and makes the broth fatty and cloudy.
• Salting before cooking — draws moisture out of the flesh.
• Skipping court-bouillon — plain water produces an inferior flavor in both fish and broth.
• Cooking whole salmon without scoring the thickest section — the thick shoulder remains undercooked.

Serving

What to Serve With Cooked Salmon

Hot with hollandaise, dill cream sauce, or beurre blanc. Cold (whole or sliced) with mayonnaise, egg cream sauce, or herb vinaigrette. Traditional Scandinavian Christmas centerpiece served whole with cucumber salad, dill, capers, and horseradish cream. Pairs with boiled new potatoes, cucumber salad, and fresh dill.

Leftovers

Storing and Reheating Cooked Salmon

Refrigerate in the cooking liquid or covered for up to 2 days. Cold salmon is excellent flaked into salads, pasta, fishcakes, and sandwiches. Reheat very gently in the broth if serving warm — salmon overcooks easily on reheating. Freezes adequately for up to 2 months.
