Preheat the oven to 375°F (190°C).

In a mixing bowl, combine melted butter, minced garlic, chopped parsley, lemon juice, salt, and pepper. Whisk until well combined.

Place the salmon fillets in a baking dish and pour the garlic butter sauce over the top, ensuring each fillet is well coated.

Bake in the preheated oven for 15-20 minutes, or until the salmon is cooked through and flakes easily with a fork.

Remove from the oven and serve immediately, garnished with additional parsley if desired.
