Ingredients You’ll Need

Each ingredient in this recipe plays a crucial role in building layers of flavor and texture. The simplicity of these essentials is what makes the dish shine, from the peppery punch of fresh arugula to the juicy brightness of lemon, and of course, the star ingredient—the salmon, giving you richness and protein.

• 3 cups arugula: Packed with peppery freshness, it forms the vibrant base of the pesto and the bed for serving.
• Top half of one bunch of green onions (roughly chopped): Adds a mild onion flavor that complements the arugula perfectly.
• 2 tablespoons lemon juice: Brightens the pesto with a fresh citrus zing.
• 2 tablespoons water: Helps create a smooth pesto texture without thinning the flavors.
• 2 tablespoons sour cream: Adds creaminess and tang to balance the herbs.
• 2 tablespoons mayonnaise: Adds richness and smooths the pesto’s consistency.
• 1 clove garlic: Infuses a subtle but essential kick to the pesto.
• 1/8 teaspoon pepper: A little heat to awaken the flavors, adjustable to taste.
• 1/4 teaspoon salt: Enhances all the other ingredients beautifully.
• 1/2 teaspoon dried basil: Adds a subtle herbal note to the pesto.
• Pinch red pepper flakes: Offers a gentle kick or more if you want some real heat.
• 4-6 salmon filets: The hearty, tender protein star with crispy skin when cooked right.
• Salt and pepper: Essential seasoning for the salmon to bring out its natural flavor.
• 1/2 teaspoon flour per filet: Helps develop a golden crust on the salmon.
• 1 tablespoon olive oil: For perfectly searing the salmon with a deliciously crisp finish.
• Fresh lemon wedges: For serving, to add a lively squeeze of citrus at the table.
• More arugula: To serve alongside, adding freshness and texture.

How to Make 20 Minute Pan-Seared Salmon with Arugula Pesto Recipe

Step 1: Whip Up the Arugula Pesto

Begin by adding arugula, green onions, lemon juice, water, sour cream, mayonnaise, garlic, pepper, salt, basil, and red pepper flakes into a food processor. Pulse everything until you achieve a smooth, vibrant green pesto. Taste it and adjust seasoning if needed—this is your flavor-packed sauce that sets the whole dish apart.

Step 2: Prep the Salmon

Pat your salmon filets dry with paper towels to ensure a perfect sear. Sprinkle salt and pepper generously on the skin side. Dust each filet lightly with about half a teaspoon of flour; this little step is the secret to a golden, crispy crust.

Step 3: Spread on the Pesto

Spread approximately one teaspoon of the freshly made arugula pesto over the skin side of each filet. This adds a beautiful layer of flavor that will infuse during cooking and give the salmon a gorgeous herbaceous coating.

Step 4: Heat the Pan

Heat the olive oil in a large skillet over high heat until it shimmers. The pan needs to be very hot to create that coveted sear without steaming the fish.

Step 5: Sear the Salmon Filets

Carefully place 2-3 salmon filets skin (with pesto) side down into the skillet, making sure not to overcrowd. Crowding lowers the pan temperature and leads to steaming instead of searing, so cook in batches if necessary. Let them cook undisturbed for 1 1/2 to 2 minutes to form a crispy crust.

Step 6: Season and Flip

Sprinkle the top side of the salmon with salt, pepper, a bit of flour, and another teaspoon of pesto. Flip the filets gently and cook for an additional 30 seconds to 1 minute. You want the fish to be cooked through but still tender and moist.

Step 7: Rest and Finish

Remove the skillet from heat and let the salmon sit in the pan for a couple more minutes. This resting period ensures the juices redistribute and the flavors fully meld together.

Step 8: Plate It Up

Serve the salmon on a fresh bed of arugula, add a squeeze of fresh lemon for brightness, and spoon a little extra pesto on top for that perfect pop of herbal flavor.

Step 9: Enjoy with Your Favorite Sides

This dish shines when paired with simple sides like a crisp green salad, crusty artisan bread, roasted potatoes, or even a light pasta—each option complements the salmon while keeping the meal balanced and satisfying.

Garnishes

Fresh lemon wedges are a must for squeezing over the salmon just before eating. A scattering of extra arugula leaves on the plate adds a fresh, peppery crunch that livens up each bite.

Side Dishes

Keep the sides straightforward to let the salmon and pesto shine: simple roasted baby potatoes tossed with olive oil and rosemary, a crunchy green salad with a light vinaigrette, or even garlic butter pasta will all complement the pan-seared salmon effortlessly.

Creative Ways to Present

Try serving this salmon over a bed of quinoa or whole grain for an added texture twist and wholesome meal. Or, plate the filets alongside grilled vegetables drizzled with extra pesto to echo that gorgeous herbaceous flavor throughout the dish.

Make Ahead and Storage

Storing Leftovers

Place any leftover salmon in an airtight container and refrigerate it within two hours of cooking. It is best eaten within 1-2 days to maintain freshness and texture.

Freezing

This dish is best enjoyed fresh; however, you can freeze salmon filets before cooking. Wrap tightly in plastic wrap and foil then store in the freezer for up to one month. Avoid freezing after cooking with pesto to preserve texture and flavor.

Reheating

To gently reheat pan-seared salmon, place it in a warm oven (around 275°F) for 10–15 minutes wrapped in foil. Avoid microwaving to prevent drying out, and add a little fresh pesto or lemon juice before serving to brighten it back up.

FAQs

Can I use other greens instead of arugula for the pesto?

Yes! While arugula gives a distinct peppery taste, spinach, kale, or even basil can be used for pesto. Just keep in mind that the flavor profile will change accordingly.

What if I don’t have a food processor?

You can finely chop the arugula, green onions, and garlic, then whisk together all pest ingredients by hand. The texture won’t be as smooth, but it will still taste delicious.

How do I know when the salmon is cooked perfectly?

The salmon should have a crispy golden skin and be opaque throughout, but still moist and tender. When you gently press the filet, it should flake slightly but not feel mushy.

Can I make the pesto in advance?

Absolutely! Arugula pesto can be made a day ahead and stored in the refrigerator in an airtight container. Just give it a quick stir before spreading it on the salmon.

Is this recipe suitable for gluten-free diets?

The recipe includes flour to help crisp the salmon skin. For gluten-free options, substitute with gluten-free flour or cornstarch in equal amounts.
