Easy Leftover Ham Casserole Recipe

I love to make this leftover ham casserole after a big family dinner or holiday. The recipe is great with any leftover ham, but especially tasty with leftover crockpot ham or baked ham with maple dijon glaze.

This casserole doesn’t lack when it comes to its creamy texture. It uses cream of mushroom soup, whole milk, and sour cream to make a super smooth and flavorful creamy base for the casserole. Of course, you can’t have a casserole without cheese. So, we add some of that too—shredded Swiss, to be exact!

Leftovers are the star of this dish, so if you have any others in your fridge, get creative and throw them in as well. Leftover roasted vegetables, peas, or roasted Brussels sprouts will be a great addition to this tasty ham casserole recipe!

Ingredients to make leftover ham casserole.

Ingredients for Leftover Ham Casserole

See recipe card below this post for ingredient qualities and full instructions.

  • Unsalted butter
  • Panko breadcrumbs – This gives the casserole topping crunch and texture.
  • Parmesan
  • Egg noodles
  • Cooked ham – Any leftover cooked ham will work.
  • Cream of mushroom soup – Any “cream of” canned soup will add loads of flavor and creaminess.
  • Whole milk
  • Sour cream
  • Garlic powder
  • Onion powder
  • Shredded Swiss cheese – The shredded cheese will melt between the noodles to make the casserole super cheesy.
  • Kosher salt
  • Black pepper


  • Use a different creamy canned soup for this casserole. I use canned mushroom soup, but you could use vegetable soup, leek soup, or chicken soup.
  • Make a meatless casserole by omitting the ham and adding your favorite vegetables in its place.
  • I’ve used Parmesan and Swiss cheese for this casserole, but you can you a different cheese, such as mozzarella if you prefer.
  • Use your favorite pasta noodles instead of egg noodles.
  • Swap the ham with cooked chicken instead for a chicken noodle casserole.

Quick Tip

Cooking the egg noodles before assembling the casserole will ensure they are cooked through and not overly chewy. Just be careful to cook just to or before al dente!

Leftovers can be transferred to an airtight container and stored in the fridge for 5 to 7 days. Or, cover it tightly with plastic wrap followed by aluminum foil, and freeze your leftover ham casserole for up to 2 to 3 months!
