Cheesy Ham and Potato Casserole

Ever since I discovered how easy it is to cook a ham in an instant pot, I buy ham whenever it is on sale! My family loves a good honey ham after church on Sunday with scalloped potatoes and homemade rolls (if I’m feeling ambitious!) but we always have a ton of ham leftover!

That’s where this ham and potato casserole comes in! While my kids love ham, they won’t just go into the refrigerator and eat any of the leftover slices because “we just had that yesterday”. (insert eye roll here)  I need to come up with other recipes that will use the leftover ham but I don’t want to spend all day in the kitchen. That’s why this casserole is the perfect recipe.

With the ham already cooked and ready to go, simply dice it and then toss it in a casserole dish with a few simple ingredients my kids love, and dinner is served!

  • You could bake this as-is, but I like to sprinkle it with just a little more cheese on top!
  • Bake at 350 degrees F for 45 minutes and you’re good to go!
