Add the pesto and softened butter to a small mixing bowl. Mix together with a fork until well combined. Set aside.

Heat olive oil in a skillet over medium heat. Season the salmon fillets on both sides with salt and pepper. Sear the salmon for 4–5 minutes on one side or until a golden brown crust forms. If the salmon is sticking to the skillet, allow a few more minutes for the crust to form. Optionally, add a few tablespoons of water to the skillet to release the salmon before flipping.

Flip the salmon fillets over and spread about 1 tablespoon of pesto butter evenly on top of each fillet. Reduce the heat to medium-low and cook for an additional 3–5 minutes, or until the salmon is flaky and cooked through. Time will depend on the thickness of the fillets.

Transfer the salmon from the skillet to a serving platter. Drizzle with any butter remaining in the pan. Squeeze fresh lemon juice over each fillet and serve immediately.
