Key Ingredients for Cheesy Ham and Potato Casserole
Ham – This recipe is a great way to use up leftover ham! If you’re not using leftover ham, purchase a fully cooked boneless ham from the store.
Shredded Cheddar Cheese – I prefer a sharp cheddar cheese for this cheesy ham and potato casserole. But if sharp isn’t your thing, go ahead and use a medium or mild cheddar. If you want to make things super easy on yourself, buy it pre-shredded!
Potatoes – I used and LOVE Yukon gold potatoes for their creamy and buttery flavor. You can use any type of potatoes you’d like, though. White potatoes would also taste great in this casserole!
Chef’s Tips
- You can prep this casserole ahead of time and bake it later on. Assemble the entire casserole in your baking dish, cover it with plastic wrap and refrigerate it. When you’re ready to bake it, remove the plastic wrap, cover it with foil and cook as directed.
- I sliced my potatoes about 1/8 to 1/4 inch thick. Don’t slice them more than 1/4 inch thick, otherwise they might not cook fully through. You can even dice your potatoes into 1/4 inch cubes if you’d like!
- When making the cheese sauce for this ham and potato casserole, let the milk and flour mixture thicken before removing from the heat. If the sauce doesn’t seem thick enough just yet, don’t worry, adding the cheese will help with that.

- 1 ½ cups ham fully cooked, divided
- 1 ½ cups milk see Notes

Notes
- Types of Potatoes: Yukon gold and yellow potatoes work best in this recipe, though any white potato will work.

Hi! You can try adding a touch more flour, and make sure your heat is low enough. It should be just a simmer, and depending on a number of factors you may need a few more minutes over low heat than we did. You could also increase the amount of cheese you add in the next step, which should help it thicken more overall, too!
