  • Place half of sliced potatoes in baking dish. Top potato layer with half of cubed ham. Repeat layers for remaining potatoes and ham. Pour cheese sauce over top layer. Top with additional 1/4 cup shredded cheddar cheese if desired.

  • Cover baking dish with foil. Bake for 45-50 minutes, or until potatoes are fork tender. Remove foil and cook for another 20-25 minutes, until cheese is brown and bubbly.

Notes

  • Potatoes: Yukon gold and yellow potatoes work best in this recipe, though any white potato will work.
  • Milk: I used whole milk for an incredibly rich cheese sauce, but you can use 2% milk if you'd like.
  • Make it Gluten Free: Use gluten-free flour instead of all-purpose flour in the cheese sauce.
