01 - Preheat the oven to 400°F. Line a baking tray with parchment paper or foil for easy cleanup.
02 - In a small bowl, combine the softened butter, pesto, minced garlic, lemon juice, salt, and black pepper. Mix thoroughly until smooth and creamy.
03 - Place the salmon fillets skin-side down on the prepared baking tray. Pat dry with paper towels to remove excess moisture.
04 - Generously spread the pesto butter mixture evenly over each salmon fillet, ensuring complete coverage.
05 - Bake for 15-20 minutes, or until the salmon is opaque throughout and flakes easily with a fork. Begin checking doneness at 15 minutes, adjusting time based on fillet thickness.
06 - Serve hot, garnished with lemon wedges and fresh basil leaves if desired.
