Halibut and Leek Gratin

Ingredients

• Halibut fillets (4 (6-ounce) fillets)
• Leeks (2 large, cleaned and sliced)
• Unsalted butter (3 tablespoons)
• All-purpose flour (2 tablespoons)
• Milk (1 cup)
• Parmesan cheese (1 cup, grated)
• Breadcrumbs (1 cup)
• Fresh parsley (2 tablespoons, chopped)
• Salt (to taste)
• Black pepper (to taste)

Instructions

1. Preheat your oven to 375°F (190°C).
2. Season the halibut fillets with salt and pepper on both sides.
3. In a large skillet, melt the unsalted butter over medium heat. Add the sliced leeks and sauté until softened and fragrant, about 5 minutes.
4. Sprinkle the all-purpose flour over the leeks and stir to coat evenly, cooking for an additional minute.
5. Gradually whisk in the milk, stirring continuously until the mixture thickens, about 2 minutes.
6. Remove the skillet from heat and fold in the grated Parmesan cheese until melted and creamy.
7. In a lightly greased baking dish, place the seasoned halibut fillets. Pour the leek mixture over the top, ensuring the fish is well coated.
8. In a small bowl, combine the breadcrumbs, chopped parsley, a pinch of salt, and a dash of black pepper. Mix well.
9. Sprinkle the breadcrumb mixture evenly over the halibut and leek mixture, creating a nice crust.
10. Bake in the preheated oven for 20-25 minutes, or until the fish is cooked through and the topping is golden and crispy.
11. Serve hot, garnished with additional parsley if desired, and enjoy the delightful blend of flavors!
