Ingredients

• 500 grams Cod fillets
• 4 tablespoons Unsalted butter
• 4 tablespoons All-purpose flour
• 2 cups Milk
• 2 cups Cheddar cheese, shredded
• 0.5 cups Parmesan cheese, grated
• 1 cup Breadcrumbs
• 1 teaspoon Dijon mustard
• 0.5 teaspoons Garlic powder
• 1 teaspoon Salt
• 0.5 teaspoons Black pepper
• 2 tablespoons Fresh parsley, chopped
• 1 as needed Cooking spray or additional butter (for greasing)

Directions

Step 1

Preheat your oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish with cooking spray or butter and set aside.

Step 2

In a medium saucepan over medium heat, melt the butter. Once melted, whisk in the flour and cook for 1-2 minutes, stirring constantly, to form a roux.

Step 3

Gradually whisk in the milk. Bring the mixture to a gentle simmer, whisking continuously, until the mixture thickens into a smooth white sauce.

Step 4

Stir in 1.5 cups of shredded cheddar cheese, all the Parmesan cheese, Dijon mustard, garlic powder, salt, and black pepper. Continue stirring until the cheese has melted and the sauce is smooth. Remove from heat.

Step 5

Arrange the cod fillets in the prepared baking dish, ensuring they are evenly spaced.

Step 6

Pour the cheese sauce over the cod fillets, spreading it evenly to ensure each piece is well coated.

Step 7

In a small bowl, combine the breadcrumbs, the remaining 0.5 cups of shredded cheddar cheese, and chopped parsley. Sprinkle the breadcrumb mixture evenly over the cheese sauce-covered cod.

Step 8

Bake in the preheated oven for 30-35 minutes, or until the topping is golden brown and the fish flakes easily with a fork.

Step 9

Remove from the oven and let rest for 5 minutes before serving. Garnish with extra parsley if desired.
