- Kosher Salt – Enhances the overall flavor. Note: Sea salt can be used as an alternative.

Step‑by‑Step Instructions for Pan-Seared Salmon With Pesto Butter
Step 1: Make the Pesto Butter
Begin by softening ½ cup of unsalted butter at room temperature to achieve a creamy texture. In a small bowl, combine the softened butter with ¼ cup of basil pesto, mixing until perfectly blended. This vibrant pesto butter will add a rich layer of flavor to your pan-seared salmon, so set it aside while you prepare the fish.
Step 2: Prepare the Salmon
Rinse the salmon fillets under cold water and pat them dry with paper towels. Season both sides generously with kosher salt and freshly cracked black pepper to enhance their natural flavor. Heat 2 tablespoons of light olive oil in a skillet over medium heat, which should take about a minute to warm up, until shimmering but not smoking.
Step 3: Sear the Salmon
Carefully place the seasoned salmon fillets in the hot skillet, skin-side down if applicable. Allow them to sear undisturbed for 4-5 minutes, keeping an eye out for a beautiful golden crust. If they stick, don’t worry—gently release them with a spatula after a minute, ensuring no skin or flesh makes a mess.
Step 4: Flip and Add Pesto Butter
Using a spatula, carefully flip the salmon fillets over once they have formed that golden crust. Spread one tablespoon of the pesto butter over each fillet, allowing it to melt and create a flavorful glaze. Now, reduce the heat to medium-low and continue cooking for another 3-5 minutes, ensuring the salmon becomes flaky and opaque.
Step 5: Check for Doneness
Monitor the salmon closely, aiming for an internal temperature of 145°F; this ensures it is perfectly cooked while still moist. Use a fork to check for flakiness; a gentle press should yield easy separation without excessive effort. Once done, turn off the heat, allowing the salmon to rest for a moment in its flavorful butter.
Step 6: Serve the Salmon
Gently transfer the pan-seared salmon with pesto butter to a serving platter. Drizzle any remaining buttery sauce from the pan over the fillets for an extra touch of flavor. For a refreshing finish, squeeze fresh lemon juice on top before serving, enhancing the dish’s brightness and elevating your Pan-Seared Salmon With Pesto Butter experience.

Choose Fresh Salmon: Quality matters! Select fresh, vibrant salmon fillets for the best flavor and texture in your Pan-Seared Salmon with Pesto Butter.

Pan-Seared Salmon With Pesto Butter Recipe FAQs
How do I choose the right salmon for this recipe?
Absolutely! When selecting salmon, look for fish that is bright in color with a fresh ocean scent. The flesh should be firm and moist, with no dark spots or a dull appearance. If possible, opt for wild-caught varieties, as they typically have a more robust flavor and texture than farmed salmon.
What’s the best way to store leftover pan-seared salmon?
Store leftover salmon in an airtight container in the fridge for up to 4 days. Ensure it’s tightly sealed to keep out air, helping maintain its moisture and flavor. When you’re ready to enjoy it again, just follow the reheating tips to warm it up without sacrificing its deliciousness!
Can I freeze the salmon with pesto butter on it?
Yes! You can freeze the cooked salmon with the pesto butter. Wrap each fillet tightly in plastic wrap, then place them into a freezer-safe bag. Squeeze out as much air as possible. Frozen in this way, the salmon can last for up to 3 months. When ready to eat, thaw it in the fridge overnight before reheating.
What if my salmon sticks to the pan while cooking?
Very common! If your salmon sticks, don’t panic. First, ensure that the skillet is adequately preheated and the oil is shimmering. If the salmon begins to stick, gently slide a spatula underneath to loosen it without tearing the flesh. Adding a splash of water around the edges can also help release it as it creates steam.
Is this dish suitable for those with food allergies?
Definitely! This Pan-Seared Salmon with Pesto Butter can be made allergy-friendly. Substitute the unsalted butter with a vegan or dairy-free alternative to accommodate dairy sensitivities. Additionally, if you have nut allergies, check your pesto ingredients; homemade options allow you to control what goes in, ensuring it’s safe for your dietary needs.
How can I customize the pesto for more flavor?
Of course! You can elevate your pesto’s flavor by experimenting with different herbs or adding ingredients like nuts or garlic. For a unique twist, try substituting half the basil with arugula for a peppery kick, or blend in some sun-dried tomatoes for a rich depth. Just remember, balance is key to keeping it harmoniously delicious with your Pan-Seared Salmon!
