01 - Preheat oven to 400°F. Line a baking sheet with parchment paper or lightly grease with cooking spray.
02 - Place salmon fillets on the prepared baking sheet, skin-side down, ensuring even spacing for proper heat circulation.
03 - In a small bowl, whisk together melted butter, minced garlic, lemon juice, lemon zest, parsley, salt, and black pepper until fully incorporated.
04 - Spoon the garlic butter mixture generously over each salmon fillet, ensuring even coverage across the entire surface.
05 - Bake for 12-15 minutes until salmon is opaque and flakes easily with a fork, reaching an internal temperature of 145°F.
06 - Remove from oven, garnish with fresh lemon slices and additional parsley if desired. Serve immediately while hot.
