01 - Preheat the oven to 400°F. Line a baking sheet with parchment paper or lightly grease it to prevent sticking.
02 - In a small bowl, combine the softened butter, chopped dill, minced garlic, lemon zest, sea salt, and black pepper. Mix the ingredients thoroughly until well blended and smooth.
03 - Use paper towels to pat the salmon fillets completely dry. Arrange the fillets skin-side down on the prepared baking sheet, ensuring they are not touching.
04 - Spread the prepared dill butter evenly over the top of each salmon fillet. Top each fillet with a couple of thin lemon slices for added flavor during roasting.
05 - Place the baking sheet in the oven and bake for 15–18 minutes. The salmon is done when it flakes easily with a fork and the internal temperature reaches 145°F.
06 - Remove the salmon from the oven. Carefully transfer the fillets to serving plates and garnish with fresh dill sprigs. Serve immediately with extra lemon wedges on the side.
