Ingredients

• 1.5 lbs fresh halibut fillet
• 1 tsp salt
• 0.5 tsp ground black pepper
• 2 tbsp olive oil
• 1 yellow onion, diced
• 3 garlic cloves, minced
• 2 celery stalks, diced
• 1 carrot, diced
• 3 tbsp butter
• 3 tbsp all-purpose flour
• 1.5 cups whole milk
• 2 tbsp fresh parsley, chopped
• 0.5 cup grated Parmesan cheese
• 1 cup shredded cheddar cheese
• 0.5 cup panko breadcrumbs

Directions

Step 1

Preheat your oven to 375°F (190°C). Grease a 9x13-inch baking dish lightly with olive oil or butter.

Step 2

Season the halibut fillet with 1/2 teaspoon of salt and 1/4 teaspoon of ground black pepper. Set aside.

Step 3

In a large skillet over medium heat, heat 2 tablespoons of olive oil. Add the diced onion, minced garlic, celery, and carrot. Cook for 5-7 minutes, stirring occasionally, until the vegetables are softened.

Step 4

Transfer the cooked vegetables to the prepared baking dish and spread them evenly across the bottom.

Step 5

In the same skillet, melt the 3 tablespoons of butter over medium heat. Stir in the flour and cook for 1-2 minutes to form a roux.

Step 6

Slowly whisk in the whole milk, ensuring no lumps remain. Cook the sauce, stirring frequently, until it thickens, about 3-5 minutes.

Step 7

Season the sauce with the remaining 1/2 teaspoon of salt, 1/4 teaspoon of ground black pepper, and 2 tablespoons of chopped fresh parsley. Remove from heat.

Step 8

Cut the seasoned halibut fillet into 2-inch chunks and arrange them atop the vegetable layer in the baking dish.

Step 9

Pour the prepared sauce evenly over the halibut and vegetables, ensuring everything is well-coated.

Step 10

In a small bowl, combine the grated Parmesan cheese, shredded cheddar cheese, and panko breadcrumbs. Mix well.

Step 11

Sprinkle the cheese and breadcrumb mixture evenly over the top of the casserole.

Step 12

Bake in the preheated oven for 30-35 minutes, or until the topping is golden brown and the casserole is bubbling around the edges.

Step 13

Let the casserole rest for 5 minutes before serving. Garnish with extra parsley if desired.
