20-Minute Garlic Butter Salmon

Starting the salmon skin-side down in a cold-ish pan is the secret to skin that crackles. Basting with garlic butter at the end does the rest. Crisp skin, a buttery pan sauce and dinner on the table before the rice is done: this is the recipe we turn to on the busiest nights of the week. It takes one skillet, a handful of ingredients and about 20 minutes from start to finish. If you have ever been disappointed by salmon that stuck to the pan, came out dry or had soft, rubbery skin, this method will change your mind about cooking fish at home.

The secret to crispy skin

Salmon skin is full of flavor, and when it is cooked well it turns as crisp as a potato chip. The trick is to render out the thin layer of fat beneath it slowly and steadily. Putting the fish into a pan that is warm rather than blazing hot gives that fat time to melt before the skin seizes up and sticks. As the pan comes up to temperature, the rendered fat essentially fries the skin from underneath.

Moisture is the other enemy. Water on the surface of the fish turns into steam, and steam makes skin soft. That is why the very first step is patting the fillets completely dry with paper towels. For even better results, leave them uncovered on a plate in the refrigerator for 20 to 30 minutes before cooking.

Ingredients

• 2 salmon fillets, skin on
• 2 tablespoons butter
• 3 cloves garlic, smashed
• 1 lemon
• Fresh thyme or dill
• Salt and pepper

You will also need a tablespoon of neutral oil with a high smoke point, such as canola or avocado oil. Look for center-cut fillets about 1 inch thick, which cook more evenly than thin tail pieces. Ask your fish counter to remove any pin bones, or run your fingers along the flesh at home and pull out any small bones with clean tweezers. Fresh or properly thawed frozen salmon both work well here.

How to make it

1. Pat the salmon very dry and season with salt and pepper.
2. Place skin-side down in an oiled pan over medium-high heat and press gently for 30 seconds.
3. Cook 6 minutes without moving, then flip.
4. Add the butter, garlic and herbs and spoon the foaming butter over the fish for 2 minutes.
5. Finish with a squeeze of lemon.

Why you press, then wait

When salmon skin first meets heat, it contracts and the fillet tries to curl up. Pressing gently on the top with a flexible spatula for the first 30 seconds keeps the skin flat against the pan so it browns evenly from edge to edge. After that, resist the urge to peek. The fish will stick at first, then release naturally once the skin is crisp. If it does not slide freely when you nudge it, give it another minute.

Basting like a chef

Once you flip the fillets, lower the heat slightly and add the butter, smashed garlic and a few sprigs of thyme or dill. When the butter foams, tilt the pan toward you so it pools at one side, then use a large spoon to scoop it up and pour it over the fish again and again. This adds rich, nutty flavor and gently finishes cooking the top. The garlic and herbs perfume the butter as they sizzle, turning it into an instant pan sauce.

How to tell when it is done

Salmon is done when the center turns from translucent to opaque and the flesh flakes easily with a fork. The FDA recommends cooking fish to an internal temperature of 145°F. Many people prefer salmon a little less cooked, so it stays silky in the middle, but if you are serving young children, older family members or anyone who is pregnant, cooking to the full recommended temperature is the safest choice. An instant-read thermometer takes out the guesswork.

Make it your own

Serve over garlicky greens or with roasted potatoes for a bigger meal.

Molly’s pairings are our go-to, but this salmon is a blank canvas. Here are a few easy ways to vary it:

• Garlicky greens: After removing the fish, toss a few handfuls of spinach or kale in the same pan for a minute.
• Lemon caper: Add a spoonful of capers with the butter for a briny kick.
• Honey mustard: Whisk a teaspoon of honey and Dijon into the pan butter.
• Herb swap: Rosemary, tarragon or parsley all work in place of thyme or dill.
• Spicy: Add a pinch of red pepper flakes to the garlic butter.

A quick weeknight plan

To get everything on the table at once, start your side dish first. If you are making rice, put it on the stove before you touch the salmon; it usually needs about 18 minutes plus a short rest. For roasted potatoes, cut baby potatoes in half, toss them with olive oil and salt and roast at 425°F for about 25 minutes while you prepare the fish.

While the side cooks, take the salmon out of the refrigerator, pat it dry and season it. Smash the garlic and pick the herbs so they are ready to go. Then, about 10 minutes before the side is finished, start the fish. By the time you squeeze the lemon over the top, dinner is ready.

Salmon is a great choice for weeknight meals because it is rich in protein and omega-3 fatty acids, which many health organizations recommend as part of a balanced diet. If you have specific dietary needs, a registered dietitian or your doctor can help you plan meals that work for you.

Leftovers

Cooked salmon keeps in the refrigerator for up to 3 days in an airtight container. The skin will not stay crisp, but the fish is delicious cold, flaked over a green salad or folded into a rice bowl with cucumber and avocado. If you prefer it warm, reheat it gently in a covered dish in a 275°F oven for about 15 minutes, which keeps it from drying out.

Buying good salmon

Great results start at the fish counter. Fresh salmon should smell clean and mild, like the ocean, never fishy or sour. The flesh should look moist and firm with bright color, and it should spring back when gently pressed. If you are buying frozen salmon, look for fillets that are vacuum-sealed with no ice crystals or freezer burn inside the package. Thaw them overnight in the refrigerator, never on the counter, and pat them extra dry before cooking because thawed fish releases more water. Wild salmon tends to be leaner, deeper in color and cooks a little faster, so start checking it a minute or two early. Farmed salmon is usually richer and more forgiving. Both are delicious with this method. Whatever you choose, ask your fishmonger for skin-on, center-cut pieces of even thickness, which cook evenly and give you the most of that crispy skin.

Key takeaway: Dry fish, a warm pan, a gentle press and patience give you crackling skin; garlic butter basting does the rest.

Twenty minutes to a great dinner

Once you master crispy-skin salmon, you have a fast, healthy dinner you can make any night of the week. It is impressive enough for guests and simple enough for a Tuesday. Add it to this week’s meal plan, scale it up for four with the servings scaler and keep cook mode on while you baste.
