01 - Preheat oven to 400°F. Line a baking sheet with parchment paper or lightly grease with cooking spray.
02 - Pat the salmon fillets dry with paper towels. Arrange them skin-side down on the prepared baking sheet.
03 - Drizzle fillets evenly with olive oil and season generously with salt and freshly ground black pepper.
04 - In a small bowl, combine softened butter, dill, minced garlic, lemon zest, and lemon juice. Mix until well blended.
05 - Spread a generous spoonful of dill butter over each salmon fillet, reserving additional butter for serving.
06 - Bake for 15 to 18 minutes, or until the flesh is opaque and flakes easily with a fork. Adjust baking time based on fillet thickness.
07 - Transfer salmon to serving plates immediately. Top with remaining dill butter and garnish with lemon wedges and additional fresh dill if desired.
