Stuffing, turkey, and mashed potatoes come together to make this hearty Thanksgiving Leftover Casserole. It’s the best way to enjoy Turkey Day leftovers!

This dish is a layered combination of turkey, stuffing, and (of course) mashed potatoes! Hard to believe, but it’s just as good as Thanksgiving dinner the first time around, if not better.

Leftover Problems = Solved!

There is nothing better than gathering together with family and friends and eating delicious food during the holidays!

And as much as we stuff our faces on Thanksgiving, we ALWAYS have leftovers, and sometimes it’s hard to use them all up without letting them go to waste. This casserole is the perfect solution!

We’ve listed the full instructions if you’re making everything from scratch OR you can use all of the previous days’ leftovers.

This specific casserole is filled with stuffing, turkey, and mashed potatoes – all the fixings from the day before! Easy, right?! Everyone needs an easy meal after all the work of Thanksgiving.

Layering Thanksgiving Casserole

Again, the recipe contains the instructions to make the stuffing and potatoes if you’re starting from scratch. But if you’re using your leftovers from Turkey Day, it’s as easy as mixing a couple ingredients together and assembling them in the following layers:

  1. Stuffing
  2. Turkey (mixed with cream of chicken soup + sour cream)
  3. Mashed Potatoes
  4. Cheese

What to do with leftover green bean casserole, cranberry sauce, or gravy? You can drizzle the gravy over the stuffing or turkey layer before baking it and get some more of that flavor incorporated. Then you can also do a layer of green bean casserole. If you still have some cranberry sauce you can serve the casserole with cranberry sauce as a “dipping sauce”.

    This turned out amazing! I used leftover stuffing, so that made it easier. Also, I used one can of cream of chicken soup and one can of cream of broccoli soup (what I had in hand). The potatoes were creamy and delicious. I highly recommend this recipe.
