  • 4 russet potatoes medium sized
  • 1/2 onion
  • 2 cups ham 1/2 inch dice
  • 1 1/2 cups cheddar and Jack cheese grated
  • 4 Tablespoons flour
  • 1/2 teaspoon salt
  • 1/2 teaspoon pepper
  • 2 cups whole milk
  • 1 Tablespoon dijon mustard
  • 1/4 teaspoon dried thyme
  • 1 teaspoon chopped parsley optional


  • Preheat oven to 350 degrees and spray a 8 x 8" baking dish with nonstick cooking spray.
  • Peel and thinly slice potatoes using a mandoline or sharp knife
  • Slice onion on mandoline
  • Place a layer of potatoes in casserole dish

  • Sprinkle with 2 tablespoons of flour and 1/4 teaspoon of salt and pepper
  • Top with 1 cup of ham and 1/2 cup of cheese
  • Repeat layers
  • Add a third layer of potatoes
  • Mix dijon mustard with a small amount of milk in a large glass measuring cup. Slowly add remaining milk, stirring as you add. Sprinkle in dried thyme. Pour milk mixture over prepared casserole.
  • Add remaining 1/2 cup of cheese
  • Cover with foil and place casserole dish on a baking sheet
  • Bake in preheated oven for one hour. Remove foil and continue baking for 30-45 minutes until top is browned, mixture is bubbly and potatoes are soft

  • Evenly distribute ingredients through each layer
