½ cup grated Parmesan cheese
¼ cup butter, softened
3 tablespoons mayonnaise
3 tablespoons green onions, chopped
2 tablespoons lemon juice
¼ teaspoon salt
1 dash hot pepper sauce
4 6oz. Halibut Fillets
Set an oven rack about 6 inches from the heat source and preheat the oven's broiler.
Remove skin from fillets. Grease a baking dish; place halibut fillets in the dish.
Broil in the preheated oven until fish flakes easily with a fork, about 8 minutes.
Meanwhile, mix Parmesan cheese, butter, mayonnaise, green onions, lemon juice, salt, and hot pepper sauce in a bowl.
Remove fillets from the oven; spread Parmesan mixture over top. Return to the oven and broil until topping is bubbly and lightly browned, about 2 more minutes.
