Ingredients
  

  • 2 T Butter
  • 3 T Diced Onions
  • 1 c Half and Half
  • 1 c Milk
  • 3 T Flour
  • ½ t Black Pepper
  • 1/2 t Salt
  • ¼ t Ground Dry Mustard
  • 1 c Shredded Cheddar Cheese
  • 1 c Shredded Monterey Jack Cheese
  • ¼ c Diced Ham
  • 1 ½ pounds of Sliced Potatoes

Instructions
 

  • Preheat the oven to 350
  • To reduce cooking time, parboil the sliced potatoes
  • Melt butter in a pan
  • Sauté the onion and diced ham in 1 T of butter and set the side
  • Make the cheese sauce by melting the remaining butter
  • Add the salt, pepper and ground mustard and stir to combine
  • Add the flour and stir until all of the flour is incorporated-it will be thick and that’s okay.
  • Add the milk and half and half to the flour mixture a little at a time whisking until it is smooth.
  • Once you have your milk and half and half incorporated add the cheeses
  • If the cheese sauce gets too thick simply remove it from the heat, adding more milk to thin it out if necessary.
  • Drain the par boiled potatoes
  • In a 9x9 pan layer the cheese sauce, potatoes, and ham and onions alternating until you reach the top of the pan finishing the layers with the cheese sauce.
  • Bake at 350 for 30 minutes covered and 5-10 minutes uncovered. Check the potatoes for doneness and if they are not soft continue cooking uncovered until your potatoes have reached your desired tenderness.
  • Enjoy!
