Name: Crisp-Skinned Seared Salmon
Prep time: 12 min
Cook time: 13 min
Total time: 25 min
Ingredients: 4 (6 oz each) skin-on salmon fillets, about 170 g each, center-cut, 2.5–3 cm thick, scaled and pin-boned; 7 g (1¼ tsp) fine sea salt; 1 tbsp neutral oil, sunflower or canola; 30 g (2 tbsp) unsalted butter; 2 sprigs thyme, or 1 crushed garlic clove; ½ lemon, cut into wedges; freshly ground black pepper

Glass-crisp skin, a barely set coral center, ten minutes in one pan

Serves: 4
Hands-on: 12 min
Total: 25 min
Level: Easy

Salmon cooked almost entirely on its skin, so the skin turns brittle like a cracker while the flesh above it warms gently. A short butter baste at the end seasons the top and brings it to a rosy, just-flaking center.

Method

Take the salmon out of the fridge 15 minutes before cooking. Pat it very dry on both sides with paper towel, pressing hard on the skin. 15 min
Run the back of a knife firmly along the skin, from tail to head, to push out moisture, then pat dry again. Season the flesh side and the skin with the salt and some pepper.
Heat the oil in a large stainless or cast-iron frying pan over medium-high heat until it shimmers and moves like water, about 2 minutes.
Lay the fillets in skin side down, laying each one away from you. Press each fillet flat with a spatula for 15 seconds so the skin doesn't curl.
Lower the heat to medium and leave them alone. Cook until the opaque band has climbed about two-thirds of the way up the side and the skin releases easily, 5–7 minutes. 6 min
Flip the fillets. Add the butter and thyme. When the butter foams, tilt the pan and spoon the butter over the fish for 1–2 minutes. 2 min
Check with a thermometer in the thickest part: pull at 48–50°C (118–122°F) for a moist, slightly translucent center, or 52–54°C (126–129°F) if you like it flaking all the way through. Without a thermometer, the center should be just turning opaque when you peek with a knife tip.
Move the salmon to plates skin side up so the skin stays crisp. Rest 2 minutes; the center climbs another 1–2°C. Serve with lemon wedges and a spoonful of the pan butter around, not over, the skin. 2 min

Why it works

Skin is mostly water, protein and fat; driving the water off with dry towels, a knife scrape and steady contact with hot metal lets the fat render and the proteins brown into a rigid, crisp sheet. The skin also insulates the flesh, so cooking mostly from one side gives you a gradient from well-browned below to barely set above. Salmon's muscle proteins tighten and push out white albumin above about 55°C, so stopping just short keeps it silky.

Common mistakes

Moving the fish too early: the skin sticks until it has crisped, then releases on its own. Wait.
A crowded or cold pan steams the skin. Use a pan big enough to leave 2 cm between fillets, or cook in two batches.
Overcooking: white beads of albumin on the surface mean it went too far. Pull earlier next time.

Variations

With salsa verde: Skip the butter baste and spoon Salsa Verde beside the fish for a sharp, herby contrast.
Skinless fillets: Sear the presentation side 2–3 minutes until golden, flip, and finish 2–4 minutes over medium-low.
