01 - Preheat your oven to 400°F. Line a baking tray with parchment paper or lightly grease it to prevent sticking.
02 - Place the salmon fillets on the prepared tray, arranging them skin-side down if they have skin.
03 - In a small bowl, whisk together olive oil, melted butter, lemon juice, minced garlic, salt, pepper, and dill until well combined.
04 - Spoon or brush the lemon-garlic butter mixture evenly over each salmon fillet, ensuring complete coverage.
05 - Arrange fresh lemon slices on top of each fillet if using, for added flavor and presentation.
06 - Bake for 12–15 minutes, or until the salmon flakes easily with a fork and is just cooked through. The internal temperature should reach 145°F.
07 - Remove from the oven, garnish with chopped fresh parsley, and serve immediately while hot.
