Ingredients for salmon and mashed potatoes

Pan-seared salmon and velvety mashed potatoes—just 12 ingredients for a restaurant-worthy comfort meal.

The salmon makes or breaks this dish, so center-cut fillets with skin are non-negotiable—they hold their shape and create the perfect crust. Wild-caught Alaskan salmon from Trader Joe's or Whole Foods delivers the best flavor, but any high-quality fillet works. Look for even thickness (about 1-inch) to ensure consistent cooking. For the potatoes, Russets or Yukon Golds are ideal—Yukons give a creamier texture while Russets hold up better to boiling. I always buy organic potatoes from Costco when I can—they're waxier and hold together better when boiling. The butter? European-style unsalted butter from Land O'Lakes or Plugrá melts beautifully without overpowering the dish.

No fresh dill? Substitute 1 tbsp dried dill but reduce to one-third the amount. Running low on heavy cream? Half-and-half plus 1 tbsp extra butter works in a pinch, though the texture won't be as rich. For the salmon seasoning, if you don't have fresh garlic, 1 tsp garlic powder plus 1/4 tsp onion powder gets you close. The mashed potatoes can use Greek yogurt instead of cream for a tangier flavor—just reduce the butter by 1 tbsp. And if you're short on lemon juice, 1 tsp white wine vinegar adds the same bright acidity. For the olive oil, avocado oil works too if you prefer a neutral flavor during searing.

Salmon fillets keep best in the coldest part of your fridge for up to 2 days—use them within 24 hours for peak tenderness. The potatoes? Store in a cool, dark place for up to 2 weeks, but don't wash them until ready to use. Once boiled, the potatoes can be reheated in the microwave with a splash of cream and butter for 3-4 days, though they're best fresh. The salmon reheats poorly, so plan to serve it immediately after searing. For meal prep, make the mashed potatoes ahead and keep them warm in a slow cooker with a lid slightly ajar—this prevents drying. The butter and cream can be pre-melted and chilled for 1 week in an airtight container.

Step-by-step instructions for salmon with mashed potatoes

Here's how to create a perfect harmony of crispy salmon and velvety mashed potatoes that will leave everyone asking for seconds.

Pat the four center-cut salmon fillets completely dry with paper towels—this is absolutely critical for achieving that coveted crust. Using the 2 tablespoons of extra-virgin olive oil, generously coat both sides of each fillet, focusing on the skin side. Let them sit at room temperature for 15 minutes while you prepare the potatoes.

While the salmon rests, season both sides with a light dusting of the 1.5 tablespoons of diamond crystal kosher salt and the 1.5 teaspoons of freshly cracked black peppercorns. I like to press the seasoning into the flesh gently with my fingertips—this ensures even distribution and maximum flavor penetration. The minced 4 cloves garlic cloves can be sprinkled over the top for an aromatic boost that will infuse the salmon as it cooks.

Peel the 2 pounds of russet potatoes and cut them into even 2-inch chunks. Place them in a large pot and cover with cold water by about 1 inch. Add 1 tablespoon of the diamond crystal kosher salt to the water and bring to a boil over high heat. Once boiling, reduce to a simmer and cook for 15-20 minutes until the potatoes are fork-tender.

While the potatoes cook, melt the 0.75 cup of unsalted european-style butter in a small saucepan over low heat. Let it melt completely but don't let it brown—you want it to remain pale yellow for the smoothest texture. In a separate bowl, whisk together the 4 whole large egg yolks and 0.5 cup of heavy whipping cream until smooth and slightly thickened.

Heat a large skillet over medium-high heat until it's properly preheated—you should see a gentle shimmer when you sprinkle a drop of water. Add the salmon fillets skin-side down and let them sear undisturbed for 4-5 minutes. You'll know they're ready to flip when the edges begin to lift and the skin turns a beautiful golden brown.

Flip the salmon carefully with a thin spatula and cook for another 3-4 minutes until the flesh is opaque throughout and flakes easily with a fork. The internal temperature should reach 145°F. Remove the salmon to a warm plate and tent loosely with foil to keep warm. Immediately pour the 2 tablespoons of fresh lemon juice into the pan and deglaze, scraping up any browned bits—these contain incredible flavor that will enhance your mashed potatoes.

Drain the cooked potatoes thoroughly, then return them to the pot. Add the melted butter and the lemon juice mixture from the salmon pan. Using a potato masher or ricer, mash the potatoes until smooth. I prefer a ricer for ultra-silky texture, but a masher works too if you're gentle.

Gradually add the egg yolk mixture while stirring continuously. The heat from the potatoes will gently cook the eggs, creating a luxurious, creamy texture. If the potatoes seem too thick, add 1-2 tablespoons of hot potato water to loosen them. Season to taste with additional salt and pepper if needed—this is where you'll notice the difference between good and extraordinary mashed potatoes.

Garnish the mashed potatoes with the chopped 0.25 cup fresh dill sprigs and 0.15 cup fresh parsley sprigs just before serving. The bright herbs will cut through the richness and add a fresh, vibrant finish. For the salmon, drizzle with any remaining lemon juice from the pan and sprinkle with additional fresh dill if desired.

Serve the salmon immediately alongside the mashed potatoes for that perfect combination of crispy exterior and tender interior paired with velvety, comforting potatoes. The acidity from the lemon brightens both components, while the herbs add a fresh finish that makes this dish truly exceptional. Every bite delivers that perfect balance of textures and flavors we all crave in a comforting meal.

Wine and beer pairings for this salmon and mashed potatoes

Crisp White Wine

For this elegant pairing, I reach for a dry Riesling from Germany or a Sauvignon Blanc from New Zealand. The acidity in these wines cuts through the richness of the butter in both the salmon and mashed potatoes, while their citrus notes mirror the lemon in the recipe.

A chilled bottle of Dr. Loosen Blue Slate Riesling or Cloudy Bay Sauvignon Blanc elevates the dish to restaurant-quality perfection. 🍷

Light-Bodied Red

If you prefer red wine, opt for a Pinot Noir with delicate fruit flavors and minimal tannins. The Willamette Valley in Oregon produces exceptional examples, like Domaine Serene or La Crema.

The wine's bright acidity and red berry notes complement the salmon's richness without overpowering the dish. Serve it slightly cooler than room temperature—around 55°F—to enhance its refreshing qualities.

Crisp Lager Pairing

A German Pilsner like Warsteiner or St. Pauli Girl provides a perfect beer pairing with its clean, crisp profile. The malt sweetness balances the acidity of the lemon, while the effervescence cleanses your palate between bites.

For a domestic option, try a crisp American lager like Budweiser or Miller Lite, which won't compete with the dish's flavors. 🍺

Craft Beer Options

For craft beer lovers, a Belgian witbier like Hoegaarden or Stella Artois offers a refreshing contrast with its citrusy coriander notes. Alternatively, a light wheat beer with a touch of spice, such as Allagash White, pairs beautifully with the dish's bright flavors.

Avoid heavy stouts or IPAs—they'll overpower the delicate salmon and mashed potatoes.

Non-Alcoholic Refreshers

For a non-alcoholic option, I love a sparkling lemonade made with San Pellegrino and fresh lemon juice. Add a splash of simple syrup> (equal parts sugar and water) and garnish with a lemon wheel.
