Fisherman's Pie
Description
This cheesy casserole has moist chunks of fish in a rich white sauce and is a great way to use up leftover mashed potatoes.
Ingredients
•
1 pound cod fillets, cut into chunks
•
3 tablespoons butter
•
2 1/2 tablespoons all-purpose flour
•
1 1/2 cups warm milk, or more as needed
•
1 cup shredded sharp white Cheddar cheese
•
1 (10 ounce) package frozen chopped spinach, thawed and drained
•
1/2 cup minced onion
•
1 teaspoon salt, or to taste
•
1/2 teaspoon ground black pepper, or to taste
•
1 clove garlic, pressed
•
2 cups mashed potatoes
•
1 cup shredded yellow Cheddar cheese
Directions
1
Preheat the oven to 375 degrees F (190 degrees C).
2
Arrange cod in a single layer in a large baking dish; set aside.
3
Melt butter in a saucepan over medium-low heat. Whisk in flour, and stir until the mixture becomes paste-like and light golden brown, 2 to 5 minutes.
4
Gradually whisk warm milk into the flour mixture and bring to a simmer over medium heat. Whisk until the sauce is thick and smooth, about 5 minutes.
5
Whisk in white Cheddar cheese, then mix onion, spinach, salt, and black pepper into the sauce.
6
Remove saucepan from heat and stir in garlic. If sauce is too thick, stir in more warm milk, 1 tablespoon at a time.
7
Pour sauce over fish in baking dish.
8
Layer mashed potatoes on top.
9
Bake in the preheated oven for 30 minutes, then sprinkle with yellow Cheddar cheese. Continue baking until fish is easily flaked with a fork, 15 to 20 minutes more.
