Ham and Potato Casserole – Great Recipe For Leftover Ham

Potato casserole recipe with chunks of ham, full of savory flavor, tender potatoes, and a creamy cheese sauce is a delicious recipe for a weeknight dinner or a delicious way to use up leftover ham. It’s a family favorite with classic flavors that appeal to everyone.

This easy cheesy ham and potato casserole is one of my favorite recipes to make with leftover holiday ham. I always make this Crockpot Brown Sugar Ham for holiday meals and the leftover perfectly flavored and hearty ham is fabulous in this comfort food casserole.

Ingredients Needed

  1. Frozen Diced Hashbrowns 
  2. Pre-Cooked Ham : This is a great ham recipe to use up those ham leftovers from Thanksgiving dinner or Christmas dinner. Or buy some packaged, chopped ham from the grocery store. 
  3. Shredded Mild Cheddar Cheese
  4. Sweet Onion
  5. Cream of Chicken Soup
  6. Sour Cream
  7. Butter : You can use salted butter or unsalted butter. If using unsalted butter I would recommend maybe adding a touch more salt. Ham itself is pretty salty, so you won’t need to add too much. But potatoes scream for tons of flavor so you will definitely need some. Maybe try 3/4 teaspoon salt if using unsalted butter. 
  8. Garlic Powder
  9. Kosher Salt & Black Pepper
  10. Onion Powder
Ingredients

How To Store Leftovers

  • Refrigerator : Store any leftover casserole inside an airtight container, in the fridge, for up to 3-4 days. You can also cover the casserole dish with a lid or plastic wrap for storage. Reheat an individual portion in the microwave until warmed through. 
  • Freezer : This casserole freezes well. Assemble the casserole, but don’t bake it. Wrap it tightly in plastic wrap and then in aluminum foil. Freeze for up to 2 months. When ready to bake, thaw the casserole in the fridge overnight and then bake as directed in the instructions. Let the baking dish sit out at room temperature for about 15 minutes before placing it into the hot oven.

What Are Some Substitutions or Variations I Can Make?
