Get the oven ready: Preheat it to 400°F (200°C). Prepare a baking sheet by either lining it with parchment paper or applying a light layer of grease to avoid sticking.

Prepare the garlic butter mixture: In a small bowl, mix the melted butter, garlic powder, Italian seasoning, paprika, lemon juice, and minced garlic. Stir until well combined.

Season the fish: Pat the cleaned fish dry with paper towels. Make 2-3 diagonal slashes on each side of the snapper to allow the flavors to penetrate. Rub the fish generously with sea salt and pepper, making sure to season inside the cavity as well.

Brush with garlic butter: Using a brush, coat the entire fish (including inside the slashes and cavity) with the prepared garlic butter mixture.

Bake the fish: Place the fish on the prepared baking sheet and add a few lemon slices on top of and inside the cavity of each fish for extra flavor. Place in the preheated oven and cook for 20 to 25 minutes, or until the fish is fully cooked and can be easily flaked with a fork. The skin should be golden and slightly crispy.

Garnish and serve: Remove the fish from the oven and sprinkle with dried parsley or garnish with fresh parsley and additional lemon slices. Serve hot with your favorite side dishes such as roasted vegetables or a fresh salad.
