01 - Preheat the oven to 400°F. Line a baking sheet with parchment paper or lightly grease it with cooking spray.
02 - Pat the salmon fillets completely dry with paper towels to remove excess moisture. Place them on the prepared baking sheet, skin-side down if applicable.
03 - In a small bowl, whisk together the melted butter, minced garlic, lemon juice, lemon zest, chopped parsley, dill (if using), salt, and black pepper until well combined.
04 - Brush or spoon the lemon garlic butter mixture generously over each salmon fillet, ensuring even coverage.
05 - Arrange a couple of fresh lemon slices on top of each fillet for presentation and extra citrus flavor.
06 - Bake for 12 to 15 minutes, or until the salmon is opaque throughout and flakes easily with a fork. The internal temperature should reach 145°F.
07 - Remove from the oven, sprinkle with additional fresh parsley, and serve immediately while hot.
