Key Ingredients

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.

  • 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.

    In a word: Yum. Simple ingredients that I had on hand thanks to hubby bringing home a x-mas cooked ham from work and had a couple of large Russet potatoes on hand. Smelled amazing while cooking, and tasted so good. I did add pepper to the sauce and greased the dish with a little butter to mitigate any possibility of sticking to the dish (it didn’t).5 stars

    Absolutely fantastic! My family loved it, and it has become a regular meal. The one thing I do differently is parboil the potatoes about 10 minutes first.5 stars

      Hi, Nim! You can leave out the onions, that’s no problem. As for the canned potatoes, we didn’t test this recipe with those so we can’t say for sure if they’ll work. If you try it, please let us know how it turns out! Keep in mind that the canned potatoes will contain more moisture so they may need to cook longer (but be careful not to burn the rest of the dish). They’re also most likely salted, so they may make the dish pretty salty.

    Made this several times for my teenage grandsons. They love it. While it resembles my Mom’s, hers did not have the sauce prepared together. This is so much better.5 stars

      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!
