How to cook salmon steak in a pan

Why It Works

• Carefully drying the salmon helps ensure that the skin does not stick, as does preheating the pan before adding the fish.
• Pressing down on the fish as soon as it hits the pan keeps the skin flat, so that the fish cooks evenly and the skin crisps all over.
• Cooking the salmon through most of the way on the first side results in more gently cooked meat that stays juicier and more tender.

Perfect pan-seared salmon should have crisp skin; moist, medium-rare, and tender flesh; and fat that has been fully rendered. But this can be tricky to achieve. The skin can stick, the salmon can easily overcook, and the layer of fat underneath the skin can come out greasy. But working through all of these problems is simple if you use the right technique.

The key is to cook the salmon most of the way through with the skin side down in order to insulate the delicate flesh from the direct heat of the pan. This technique produces excellent results with minimal fuss.

Get Good Salmon

Whether you go for king, coho, or sockeye, you want salmon fillets that are firm and bright-looking, with shiny skin and resilient flesh. Fresh fish should spring back into place if you press it—if the fish holds a fingerprint, take it back to the fishmonger and give 'em hell for next time.

Center-cut fillets will be the prettiest and most evenly shaped for pan-searing, though this technique will work for any kind of fillet. A five- to six-ounce fillet is a reasonable portion for one person.

Dry It Carefully and Season It Well

In order to prevent salmon skin from sticking, it's important to start with a hot pan (more on that in a moment). Moisture left on the surface of the fish can quickly suck away heat from even a well-preheated skillet, so it's equally important to dry your fish carefully by pressing it between a couple of paper towels.

After drying, make sure to season the salmon generously with salt and pepper on both sides. If you have a little time to spare, seasoning it at least 45 minutes in advance and letting it rest in the fridge up to several hours can help the fish retain more moisture as it cooks. (If you don't have at least 45 minutes, it's best to season right before cooking, to prevent moisture drawn out by the salt from interfering with crisp skin.)

Always Preheat the Oil

Preheat a thin layer of oil in a stainless steel, cast iron, or carbon steel skillet over medium-high heat until it starts to shimmer. This is the most important step. If salmon enters a pan that's too cold, it can actually form a chemical bond with the metal, making it impossible to flip without tearing up the skin. Preheating the pan and oil will rapidly set the proteins in the fish before it has a chance to start bonding.

Though you want fairly high heat at the start, cooking at that temperature the entire time will lead to the salmon overcooking on its outer layers, which can cause it to turn chalky and leak unsightly white albumen. So, just before adding the fish, lower the heat under the pan to medium-low.

Add the Fish With Confidence and Press It Down

Carefully add the fish to the pan, using your hands and lowering it away from you so that you don't accidentally hit yourself with hot oil. Remember: Hot pans can sense fear. Lay the fish in gently and confidently rather than dropping it in, which can lead to dangerous splashes.

Left unattended, salmon skin will buckle and curl, which can make the fish cook unevenly. To avoid this, as soon as the salmon is in the pan, press gently but firmly on the back of it for about 10 seconds with a flexible, slotted fish spatula. If you're cooking multiple fillets at a time, add them to the pan one at a time, pressing each for 10 seconds before adding the next.

Cook Through on Skin Side Before Flipping

This is the big trick for salmon. Salmon skin typically has a thick layer of fat underneath it. This fat needs to be rendered to get the skin crisp and pleasant. Fat is also a great insulator, which means that cooking the salmon skin side down is much gentler on the flesh than cooking it with the skin facing up. I like to cook my salmon about 90% of the way through with the skin side down, in order to take advantage of the skin's insulating properties and render fat in the process.

For salmon with a nice, translucent medium-rare center, cook until an instant-read thermometer inserted into the very center of the fillet registers 120°F (49°C). This will take about six minutes for a large fillet like the one pictured.

If your heat management was on point, the salmon skin should be nice and crisp by the time the center of the fish has reached 120°F. This should make it easy to lift and flip. I like to use that same flexible spatula to turn the fish, and use a second spatula or a fork to help get leverage. Be gentle when flipping the fish: You don't want to damage it, nor do you want it to splash down and splatter hot oil.

Cook Very Briefly on Second Side, Rest, and Serve

Because the salmon is pretty much cooked through already, all it needs is a quick kiss of heat on the second side to finish. Just about 15 seconds is enough.

Transfer the salmon to a paper towel–lined plate to drain off any excess oil, and let it rest for a couple of minutes before serving.

Now this is how salmon should be! Crispy and juicy.

January 2017

• 4 skin-on salmon fillets, about 6 ounces (170g) each

• Kosher salt and freshly ground black pepper

• 2 tablespoons (30ml) vegetable, canola, or light olive oil

1. Press salmon fillets between paper towels to dry surfaces thoroughly. Season on all sides with salt and pepper.

2. In a large stainless, cast iron, or carbon steel skillet, heat oil over medium-high heat until shimmering. Reduce heat to medium-low, then add a salmon fillet, skin side down. Press firmly in place for 10 seconds, using the back of a flexible fish spatula, to prevent the skin from buckling. Add remaining fillets one at a time, pressing each with spatula for 10 seconds, until all fillets are in the pan.

3. Cook, pressing gently on back of fillets occasionally to ensure good contact with skin, until skin releases easily from pan, about 4 minutes. If skin shows resistance when you attempt to lift a corner with spatula, allow it to continue to cook until it lifts easily. Continue to cook until salmon registers 110°F (43°C) in the very center for rare, 120°F (49°C) for medium-rare, or 130°F (54°C) for medium, 5 to 7 minutes total.

4. Using spatula and a fork, flip salmon fillets and cook on second side for 15 seconds, then transfer to a paper towel–lined plate to drain. Serve.
