01 - Preheat the oven to 400°F. Line a baking sheet with parchment paper or lightly grease an ovenproof dish.
02 - Pat salmon fillets dry and arrange them on the prepared baking sheet. Brush each fillet with olive oil and season generously with salt and freshly ground black pepper.
03 - Bake the salmon for 12 to 15 minutes, until just cooked through and easily flaked with a fork. The internal temperature should reach 145°F.
04 - While the salmon bakes, melt butter in a small saucepan over medium heat. Add minced garlic and sauté for 1 minute until fragrant.
05 - Stir in heavy cream, lemon zest, and fresh lemon juice. Reduce heat and simmer gently for 2 to 3 minutes, stirring occasionally.
06 - Remove from heat and mix in chopped dill. Season with salt and pepper according to taste.
07 - Plate the baked salmon fillets and spoon the warm dill and lemon sauce over each. Garnish with lemon slices and extra dill sprigs.
