01 - Set the oven to 400°F. Prepare a baking dish by lining it with parchment paper or lightly greasing it.
02 - Pat the halibut fillets dry using paper towels and arrange them in a single layer within the prepared dish.
03 - Combine melted butter, olive oil, lemon juice, minced garlic, lemon zest, sea salt, and black pepper in a small bowl; whisk until integrated.
04 - Brush the butter mixture thoroughly over each halibut fillet to coat evenly.
05 - Evenly sprinkle the chopped parsley, dill, and chives over the coated fillets.
06 - Place the dish in the oven and bake for 15 to 18 minutes until the halibut flakes easily with a fork and appears opaque throughout.
07 - Remove the baked halibut from the oven and allow it to rest for 2 minutes before serving. Optionally, accompany with lemon wedges.
