Delicious Cheesy Ham and Mashed Potato Casserole is a great way to use up leftover spiral baked ham and mashed potatoes from a big holiday dinner!
After the holidays, we always have tons of leftovers.
Ham, turkey, veggies, rolls… and mashed potatoes. Always gallons and gallons of mashed potatoes!
This year, I came up with a delicious twist on a mashed potatoes that is SO incredibly easy and delicious- and it’s a great way to use up all those mashed potatoes (and honey baked or spiral ham).
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.
This is an awesome recipe to have ready after your next big holiday dinner (or anytime you’re making a big spiral cut ham dinner and mashed potatoes).
You could also top this with crunchy onions, bacon, pancetta- or mix in peas, roasted carrots or turnips, and any other veggie you have leftover on hand!
I’m bummed I used up all our leftovers- because I really want to make this casserole again soon! It really is that good (and easy!!).
