Use up all your delicious Thanksgiving leftovers to make a casserole. Layers of mashed potatoes, turkey, green bean casserole, gravy, and stuffing, all topped with tart cranberry sauce.

You have just spent the better part of two days cooking, serving, eating, and washing dishes. The last think you want to think about is making yet another meal!

And when you open the fridge, it’s stuffed with containers full of leftovers. So even if you wanted to make dinner, there is no room to put anything else in there.

All the delicious leftover stuffing, mashed potatoes, and green bean casserole get turned into another yummy meal that is easy to put together. Make life even easier and just assemble the casserole as you are putting away the leftovers from dinner.

Ingredient Notes

• Turkey – Feel free to substitute rotisserie chicken if you don’t have any leftover turkey. This is also a great way to use up the leftover turkey dark meat.
• Mashed potatoes – Substitute store bought if you don’t have any leftover mashed potatoes or add more stuffing.
• Dressing – Depending on what you have more of you can use all potatoes or all leftover stuffing.
• Green beans – I prefer to use leftover green bean casserole but you can always substitute frozen or canned green beans.
• Gravy – This is usually the first thing to disappear so you can make new gravy or substitute cream of mushroom soup.
• Cranberry – Use up any leftover cranberry sauce you have or you can always open up a can of whole cranberry sauce. Or leave off all together.
• Fried onions – You can use up any you might have leftover or you can always leave these off if you like.

How To Make Thanksgiving Leftovers Casserole

For the full recipe and detailed cooking instructions, please see the recipe card at the end of this post.

How long does it last?

You are already using food that is previously cooked, so I would only keep the leftovers for 1-2 days. I’m sure you don’t want to eat turkey three days in a row anyway.

Also, don’t use the leftovers to make the casserole if they have been in the fridge for more than 4 days. It’s best to make the casserole as soon as you can after Thursday.

Can I freeze it?

I like this option the best. I don’t really feel like eating turkey and mashed potatoes again so soon after Thanksgiving. So I usually assemble the casserole and freeze it.

Then, in a few weeks when I am craving comfort food, or need an easy meal during the busy holiday season, I grab this from the freezer. It will freeze well for up to 2 months. Thaw overnight in the fridge and bake it the next day.

Serving Suggestions

Since this casserole has all the best leftovers, I like to serve mine with a salad or topped with extra cranberry sauce to freshen it up a bit.

You can always take a slice of this and put it on a sandwich!
