Cheesy Scalloped Potatoes with Ham

4 cups peeled and sliced potatoes

2 cups diced ham

½ onion, chopped

2 cups milk

1 cup frozen peas

3 tablespoons all-purpose flour

2 tablespoons butter

½ teaspoon salt

½ teaspoon ground black pepper

⅛ teaspoon garlic powder

⅛ teaspoon onion powder

1 teaspoon dried parsley

¼ pound Cheddar cheese, diced

1 pinch paprika, or to taste

Preheat oven to 350 degrees F (175 degrees C).

Layer half the potatoes, half the ham, and half the onion in an 2-quart baking dish; repeat the layers.

Heat milk, peas, flour, butter, salt, black pepper, garlic powder, and onion powder in a saucepan over medium heat, stirring constantly, until thickened, 7 to 10 minutes.

Stir Cheddar cheese into sauce until cheese is melted.

Pour sauce over potato and ham mixture; sprinkle with paprika.

Cover baking dish with aluminum foil.

Bake in the preheated oven until potatoes are tender, about 1 hour.

Remove foil and continue baking until lightly browned, about 15 minutes more.
