01 - Preheat your oven to 400°F. Line a baking sheet with parchment paper or lightly grease it to prevent sticking.
02 - Gently pat the salmon fillets dry with paper towels. Place them skin-side down on the prepared baking sheet.
03 - Brush the tops of the fillets evenly with olive oil. Season generously with salt and freshly ground black pepper.
04 - In a small bowl, combine the softened butter, finely chopped dill, lemon zest, fresh lemon juice, and minced garlic. Mix thoroughly until all ingredients are well blended and fragrant.
05 - Spread a thin, even layer of the prepared dill butter over the top of each salmon fillet. Reserve approximately half of the dill butter mixture for serving later.
06 - Bake the salmon in the preheated oven for 14–18 minutes, or until the fish flakes easily with a fork and appears just opaque in the center. Cooking time may vary based on fillet thickness.
07 - Carefully remove the baking sheet from the oven and allow the salmon to rest for 2 minutes. This helps the juices redistribute, ensuring a moist and tender result.
08 - Top each cooked fillet with a dollop of the reserved dill butter. Garnish with extra fresh dill sprigs and lemon wedges, if desired, before serving immediately.
