Thanksgiving Leftovers Casserole

Thanksgiving leftovers. If you've got them, you need ways to use them up in the most delicious ways. This Thanksgiving Leftovers Casserole is just the thing to repurpose those leftovers into a completely different dish the whole family will enjoy!

This leftovers casserole is a tasty way to use up Thanksgiving leftovers (turkey, mashed potatoes, stuffing).

In this easy recipe, leftover stuffing makes the "crust" layer, followed by a creamy leftover turkey/vegetable layer then topped with cheesy mashed potatoes.  It's a snap to assemble and only takes 30 minutes to bake up!

I'll be honest, when I made it, I was really skeptical. Especially with the mayonnaise ingredient.  I didn't think this would be something myself or my family would like...but we ended up really enjoying it. The mayo actually gave it a nice creaminess! Who would have thought?

I have to admit, my family is not big on leftovers.  We will usually do one more meal after Thanksgiving with the leftovers in their original state, but after that, they just seem to sit.

When I am able to repurpose leftovers into something different, my family is more apt to eat them.  Since I hate wasting food, I like having an arsenal of ideas to use them up with.

Thanksgiving "anytime of the year" Casserole

If you don't have any leftover ingredients on hand, or are missing an ingredient, this leftover casserole can also be assembled using leftover chicken, prepared instant mashed potatoes, prepared instant stuffing, and frozen veggies!

It's a comforting casserole that says, "Happy Thanksgiving" in every bite!

Does your family eat leftovers?  Have you ever used leftovers to create a whole new meal?

  1. Does this casserole not scream comfort or what? We usually have leftovers but I traditionally make soup, salads or sandwiches! Nothing crazy ;)

  2. What great ideas! I'm in love with leftovers, but my husband doesn't like them so much so reinventing them is a must at our house. This casserole looks delicious and your other links are great ideas as well!

  3. These are great ideas and I'm sure we'll have a ton of leftovers this year. Thanks!

  4. Looks like you have the leftovers covered Renee! Lots of good ideas and recipes galore. My mom usually divided up her leftovers and sends them home with the guests so she isn't left with too much. I will probably do the same thing this year since we are empty nesters!

  5. I love leftovers! These are great ideas!
    I especially like the Classic Ham and Bean Soup and the lightened Up Sweet Potato Pie!
