1 lb cod fillets, cut into chunks

3 tbsp butter

2½ tbsp all-purpose flour

1½ cups warm milk, or more as needed

1 cup white cheddar cheese, shredded, sharp

10 oz frozen spinach, (1 package), thawed and drained

½ cup onion, minced

1 tsp salt, or to taste

½ tsp ground black pepper, or to taste

1 garlic clove, pressed

2 cups mashed potatoes

1 cup yellow Cheddar cheese, shredded

Preheat the oven to 375 degrees F. Arrange cod in a single layer in a large baking dish; set aside.

Melt butter in a saucepan over medium-low heat. Whisk in flour, and stir until the mixture becomes paste-like and light golden brown.

Gradually whisk warm milk into the flour mixture and bring to a simmer over medium heat. Whisk until the sauce is thick and smooth.

Whisk in white Cheddar cheese, then mix onion, spinach, salt, and black pepper into the sauce.

Remove saucepan from heat and stir in garlic. If sauce is too thick, stir in more warm milk, 1 tablespoon at a time.

Pour sauce over fish in baking dish. Layer mashed potatoes on top.

Bake in the preheated oven for 30 minutes, then sprinkle with yellow Cheddar cheese. Continue baking for 15 to 20 minutes more until the fish is easily flaked with a fork.
