01 - Preheat the oven to 400°F. Line a baking sheet with parchment paper or lightly grease it.
02 - Pat salmon fillets dry with paper towels. Brush both sides with olive oil and season evenly with salt and pepper. Arrange fillets skin-side down on the prepared baking sheet.
03 - In a food processor, combine basil leaves, pine nuts, Parmesan cheese, garlic, olive oil, lemon juice, and salt. Blend until a smooth pesto forms, scraping down the sides as necessary.
04 - Spread 1 to 2 tablespoons of pesto evenly over each salmon fillet.
05 - Place salmon in the preheated oven and bake for 15 to 18 minutes, until salmon flakes easily and is cooked through.
06 - Serve hot, garnished with lemon wedges and fresh basil leaves as desired.
