Ham and Scalloped Potatoes Recipe

Ham and Scalloped Potatoes Recipe

  • cooking spray
  • 8 potatoes, peeled and thinly sliced
  • 1/2 cup butter
  • 1 onion, finely chopped
  • 1/2 cup all-purpose flour
  • 2 teaspoons Dijon mustard
  • 1 teaspoon salt
  • 1/4 teaspoon ground black pepper
  • 3 cups milk
  • 2 cups shredded Cheddar cheese
  • 3 cups diced ham
  1. Preheat oven to 350 degrees F (175 degrees C). Spray a 9×13-inch baking dish with cooking spray.
  2. Bring a large pot of water to a boil. Add sliced 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.
  3. 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.
  4. Layer half of the potatoes in the bottom of the prepared baking dish. Top with 1 1/2 cup diced ham and half of the Cheddar cheese sauce. Repeat layering potatoes, ham, and sauce.
  5. Bake in the preheated oven until the top is lightly browned, about 1 hour.
