This casserole was so easy to make it came together in under five minutes (just chop up some cold leftover ham, shred some cheese, and dump it all in a bowl) – and can even be made as a one-pot meal if you mix it all in the bowl you’re going to cook it in.

If you have some leftover browned onions or crispy onions from thanksgiving (or any other veggies you love), go ahead and toss them in! We had some leftover onions which were perfect in this casserole- but you could also just add in raw diced onion, too.

This casserole is so delicious and easy- when I made it, it disappeared in seconds. My husband and my in-laws happily scooped it all up and even grabbed seconds! It was gone in a flash… and we were all quite full and happy.
