01 - Preheat oven to 400°F. Line a baking dish with parchment paper or lightly grease with oil.
02 - Pat fish fillets dry with paper towels. Season both sides generously with salt and pepper. Arrange in a single layer in the prepared baking dish.
03 - In a small bowl, whisk together melted butter, lemon juice, lemon zest, minced garlic, parsley, and dill until well combined.
04 - Pour the lemon butter sauce evenly over the fish fillets, ensuring complete coverage.
05 - Top each fillet with a lemon slice for added flavor and presentation.
06 - Bake for 15 to 20 minutes, or until the fish flakes easily with a fork and appears opaque throughout.
07 - Remove from oven, garnish with extra parsley, and serve immediately while hot.
