Instructions for Making This Recipe
- Pat the salmon fillets dry with paper towels, then season generously with salt and pepper on both sides. Set aside.
- Heat a skillet over medium heat and add olive oil. Once the oil shimmers and just begins to smoke, carefully place the salmon fillets skin-side down. Press gently to ensure contact with the pan.
- Sear the salmon for about 4-5 minutes until the skin is crispy and golden. You’ll notice the color change and a delightful sizzle. Flip the fillets carefully using a spatula, and cook for another 2-3 minutes until the flesh is opaque and flakes easily.
- Remove the cooked salmon from the skillet and place on a plate to rest briefly. Keep warm while you prepare the lemon butter sauce.
- Add the minced garlic to the same skillet and cook for about 30 seconds until fragrant, with a gentle sizzle. Then, squeeze in the fresh lemon juice and add the lemon zest, stirring to loosen any browned bits from the bottom of the pan.
- Pour in the butter and let it melt slowly, swirling the pan to create a glossy, fragrant lemon butter sauce. Cook for about 1 minute until slightly thickened and fragrant.
- Return the salmon to the skillet, spooning the lemon butter sauce over the top. Let it sit for a minute so the flavors meld and the fish stays moist and flavorful.
- Garnish with chopped herbs if desired, and serve immediately with a drizzle of the lemon butter sauce. The skin should be crispy, the flesh tender and flaky, with a vibrant, glossy lemon glaze.
