Thanksgiving Leftovers Casserole

This is one of my all-time favorite things that my grandma made when we were kids. It wasn’t only for Thanksgiving leftovers; any time she had leftovers sitting in the refrigerator, she would whip this up. It’s perfect for using up whatever you have; the meld of flavors is simply awesome. You basically layer stuffing, then turkey, then leftover vegetables (green beans, mushrooms, corn and peas are all exceptionally good in this), top it with leftover mashed potatoes, and then sprinkle with some shredded cheese. Bake till it’s heated through and the cheese is melted. This is seriously delicious, and reminds me of stopping at grandma’s on a random weeknight and her making this for dinner. It’s definitely comfort food, and a perfect way to use up turkey leftovers!

What’s your favorite way to use up Thanksgiving leftovers?

I hope everyone had a fabulous holiday yesterday, and if you’re out shopping today, hope you find some good deals!

Thanksgiving Leftovers Casserole

Yield: 6 to 8 servings

Prep Time: 10 minutes

Cook Time: 30 minutes

Total Time: 40 minutes


2 tablespoons butter
1 onion, chopped
2 cups of leftover vegetables (green beans and mushrooms are my favorites in this)
2 cups of leftover stuffing
2 cups leftover turkey (or any other meat)
1 can cream of mushroom soup (optional, I don't add it, but it's in the original recipe)
2 cups leftover mashed potatoes
2 eggs
1 cup shredded cheddar cheese


1. Preheat the oven to 350 degrees F.

2. Melt the butter in a skillet over medium heat and saute the onion until soft and translucent, about 5 minutes. Stir in the remaining vegetables and the turkey. Mix together and remove from heat.

3. In a casserole dish (9x13-inch), spread the stuffing over the bottom. Add the turkey and vegetable mixture and spread evenly on top of the stuffing. If using, add the can of cream of mushroom soup and spread on top of the meat and vegetable mixture. In a medium bowl, mix together the mashed potatoes and the eggs until thoroughly combined. Spread this on top of the turkey and vegetable mixture (or the cream of mushroom soup, if you used it). Top with the shredded cheese.

3. Bake for 25 to 30 minutes. Let stand 5 to 10 minutes before serving.

    Oh, we were just talking about this last night! Unfortunately the only thing we have significant leftovers of is the mashed potatoes. For Christmas, though, I’m planning to have enough for something like this! :o)

      Perfect for fried potato pancakes! 🙂

    Looks like a great way to use leftovers. I like to make a potpie. I love the recipe card, I get to old lump in the throat when I come across a hand written recipe my mom wrote, she passed 7 years ago ,but I’m so happy to have these little tid-bits of her.You better be out shopping at all the great places you guys have there!


    • Michelle on November 29th, 2010 at 4:53 pm

      I actually didn’t do any shopping on Friday, believe it or not! I was on the couch, watching the Pens, and recovering from Thursday 😉

    this is brilliant! I am going to see if I can convince s. that we should do this this evening – we have all the fixin’s for it! I might do a mini version of it with my leftovers whether he does with his or not. Thanks for the idea!

  7. Maria on November 26, 2010 at 4:35 pm

    Great way to use up those leftovers! I love family recipes. Great food and memories!


  8. Dea on November 26, 2010 at 5:18 pm

    I’ve done this before… in lieu of the cream of mushroom soup i’ll use leftover gravy!


    • Michelle on November 29th, 2010 at 4:54 pm

      Dea – AWESOME idea to use the leftover gravy in place of the canned soup!


  9. anne-marie on November 26, 2010 at 8:25 pm

    That sounds so good! My favorite leftover meal is stuffing, turkey, gravy all in a pan heated up. Its amazing! I made extra gf stuffing and gravy to ensure I could still eat this!

    This casserole is so ingenious and yet it delivers great taste! thanks for the inspiration I will make it soon, even with a leftover plain roasted chicken!


  12. Val on November 27, 2010 at 6:45 pm

    Oh my!! thank you so much for the leftover thanksgiving idea. I mixed the gravy with some cut up turkey in lieu of the mushroom soup. What a great idea and delicious at that. This will be my go to way of serving leftovers from here on in @ thanksgiving. thank you for ALL of your posts. Ii do so enjoy them! Val


    • Michelle on November 29th, 2010 at 4:55 pm

      You are very welcome! I’m glad you enjoyed the casserole, and love the idea of using gravy in place of the soup!

    Mmmmm… looks delicious! My mom has a whole box of those recipe cards with a whole section for Thanksgiving, and I’ll be adding this to the collection! I’m just wondering though, why would you need to mix eggs with the mashed potatoes?


    • Michelle on November 29th, 2010 at 4:56 pm

      Mixing the eggs with the mashed potatoes keeps them from drying out in the oven and keeps them creamy.


      • Zuzu on November 29th, 2010 at 6:15 pm

        Oh, I see 🙂 Thanks! Can’t wait to make this. Thanksgiving isn’t over until the leftovers are!


  14. Latin Lovin Eatin Grubbin on November 28, 2010 at 6:18 pm

    Love the casserole idea. I’ll try it out tonight. I came up with a good turkey salad recipe on my site. Feel free to check it out.


  15. Caryn on November 28, 2010 at 7:24 pm

    This is absolutely wonderful! I had cream of chicken soup and used that…so good! Thank you!


  16. Tricia @ {every}nothing wonderful on November 29, 2010 at 11:58 pm

    I love that you skip the canned soup. LOVE IT! Adding to the leftovers list! Thanks!


  17. Fred on February 5, 2011 at 4:30 am

    I have done this one and now I look forward more to the leftovers than the original dinner…as stated GREAT comfort food


  18. julie on November 18, 2012 at 11:06 am

    thanks for this recipe. was looking for one exactly like this. Your original recipe made me think of something my sister is doing for the family for Christmas. She has collected old recipes handwritten from grandmas, aunts etc… and has scanned them and sent the scans to spoon (i think that’s the site) where they then turn it into fabric. She is making tablecloths, dish towels and aprons out of these scanned recipes. Just thought I’d mention 🙂
    Off to make this casserole now. Thanks!
