01 - Preheat the oven to 400°F. Line a baking dish with parchment paper or lightly grease the surface.
02 - Pat the halibut fillets dry using paper towels and arrange them in the prepared baking dish. Brush both sides with olive oil and season evenly with salt and black pepper.
03 - In a small mixing bowl, whisk together the melted butter, minced garlic, lemon juice, and lemon zest until well combined.
04 - Spoon the garlic lemon butter mixture evenly over the seasoned halibut fillets.
05 - Place the dish in the oven and bake for 15 to 18 minutes, or until the halibut is opaque and flakes easily with a fork. Adjust time slightly for thicker cuts.
06 - Remove from the oven, sprinkle with fresh parsley, and serve immediately accompanied by lemon wedges.
