Fiskgratäng

Fiskgratäng is a delicious Swedish fish casserole made with white fish, creamy sauce, and topped with breadcrumbs and cheese.

Ingredients - Serves 4

Preheat the oven to 375°F (190°C).
In a large skillet, melt the butter over medium heat. Add the chopped onion and cook until softened.
Add the flour to the skillet and cook for 1-2 minutes, stirring constantly.
Gradually whisk in the milk, making sure there are no lumps. Cook until the sauce thickens.
Stir in the Dijon mustard, lemon juice, salt, and pepper.
Place the fish fillets in a greased baking dish. Pour the sauce over the fish.
In a small bowl, mix together the breadcrumbs and grated cheese. Sprinkle the mixture over the fish and sauce.
Bake in the preheated oven for 25-30 minutes, or until the fish is cooked through and the topping is golden and crispy.
Serve the fiskgratäng hot with a side of steamed vegetables or a fresh salad.
