Got Thanksgiving leftovers piling up? Don’t let them go to waste! This easy Thanksgiving Leftover Casserole turns all your favorite fixings into a warm, hearty, and comforting dish everyone will love. While this post is sponsored by Florida Dairy Farmers, all opinions and my love of dairy are my own.
Easy Thanksgiving Leftover Casserole
Thanksgiving is filled with lots of food. And most of the time we never eat it all. I mean, how can you? Between the amazing turkey, traditional green bean casserole, flavorful stuffing, creamy mashed potatoes, corn, rolls and the gravy to pour on top of everything you always end up Thanksgiving leftovers. Which isn’t a bad thing, Thanksgiving leftovers are just as delicious as the original meal. But sometimes we need a little inspiration on how to repurpose those yummy Thanksgiving leftovers.
Which is exactly why I made the tastiest and easiest Thanksgiving Leftover Casserole you will ever have. You literally layer all your Thanksgiving leftovers into a casserole dish, bake and enjoy. And don’t we all deserve an easy meal after all that cooking we did on Thanksgiving? Yes, yes we do.
Ingredients for Thanksgiving Leftover Casserole
Turkey
Cranberry Sauce
Canned corn – fresh is fine too
Green bean casserole
Gravy
Milk
Stuffing
Those are our Thanksgiving dinner staples, if you have anything else leftover that you think may be good in your Thanksgiving leftover casserole, go ahead and add it in.
Variations & Add-Ins
- Feel free to add other leftovers like roasted vegetables or sweet potatoes.
- You can top your casserole with candied pecans and fresh cranberries before serving. It gives your casserole a bit of color and a bit of crunch…both were a perfect Thanksgiving addition, but it is just as good without them if you would rather not add them.
- Use this casserole for Christmas leftovers too!
How Long Are Thanksgiving Leftovers Good For?
Leftovers are generally good for 3-7 days in the refrigerator and 2-3 months in the freezer, so be sure to use them before you have to throw them away.
- Cooked turkey is good for 3-4 days in the refrigerator. If you don’t think you will use it that quickly, toss it in the freezer.
- Prepared stuffing is good for 3-4 days in the refrigerator and about a month in the freezer.
- Mashed potatoes are good for 3-5 days in the refrigerator. If you put them in the freezer, they will stay good for up to a year.
- Cranberry sauce is still fresh if kept in the refrigerator for up to 10-14 days. If you still have leftover cranberry sauce after making this delicious casserole, make this easy Cranberry Jello Salad, it’s delicious!
Now that we know how long your Thanksgiving leftovers are good for, let’s get to the recipe that you are going to make to use them all up!
I recommend serving my casserole with a tall glass of cold milk. Milk contains 13 essential nutrients and 8 grams of high-quality protein in every 8-ounce glass!
If you would like a glass of wine to pair with it, here are my recommendations:
Pinot Noir – Light to medium-bodied with bright red fruit and subtle earthiness, it pairs beautifully with turkey, stuffing, and cranberry. Perfect if you want something versatile.
Chardonnay (unoaked or lightly oaked) – A medium-bodied Chardonnay has enough body for the gravy and stuffing but won’t overwhelm the cranberry or green beans.

This recipe will fill your 9×13 baking pan, so we were actually able to eat it again… for leftovers 😉 Feel free to freeze leftovers for up to a month if you don’t get the chance to eat it all and need a break from all that Thanksgiving deliciousness.
You can also half the recipe if you don’t have as many leftovers. If you do half the recipe, use an 8×8 baking pan.
