Scalloped Potatoes and Ham
These scalloped potatoes and ham are cooked in a delicious homemade cheese sauce. If you prefer a little kick, try adding a dash of cayenne pepper to the sauce. 
cooking spray

8
butter
½
cup

1
all-purpose flour
½
cup
Dijon mustard
2
teaspoons
salt
1

ground black pepper
¼
teaspoon

3

2

 Preheat the oven to 350 degrees F (175 degrees C). Spray a 9x13-inch baking dish with cooking spray.
  Bring a large pot of water to a boil. Add potatoes and cook until almost tender, 5 to 10 minutes. Transfer to a colander and rinse with cold water until cool enough to handle. Drain well and set aside.
  Melt butter in a large skillet over medium heat. Add onion; cook and stir until tender, about 5 minutes. Stir in flour, Dijon mustard, salt, and pepper; cook for 1 minute. Gradually pour in milk, stirring constantly until sauce is thickened, about 5 minutes. Stir in Cheddar cheese until melted.
  Layer ½ of the potatoes in the bottom of the prepared baking dish. Top with 1 ½ cups diced ham and ½ of the Cheddar cheese sauce. Repeat another layer with remaining potatoes, ham, and sauce.
  Bake in the preheated oven until the top is lightly browned, about 1 hour.
