Leftover Turkey Casserole
Thanksgiving Leftover Casserole came about a couple of holidays ago when I was staring down a fridge full of plastic containers. Heating up leftovers separately in the microwave can take forever, and frankly, I just didn’t have it in me. So, I created this casserole and our leftovers have never been the same!
This Thanksgiving Dinner Leftover recipe is so easy. It all cooks at the same time and can easily be modified according to how much of each leftover you have. If you have a ton of leftovers, you can double this recipe and cook it in a 9×13 pan.
You can also adapt the ingredients you use in the casserole to fit your preferences, tastes, and what you have left over in the fridge from Thanksgiving Dinner. Plus, we have a some other surprise Thanksgiving leftover recipe ideas too!
Cost Saving (& Delicious) Thanksgiving Casserole
I like using my leftovers from Thanksgiving in a casserole because it will feed my family for another meal or two, and I, for one, think it tastes better than heating up everything in the microwave! Serve it with some leftover rolls and it is a hot meal with all of the wonderful tastes of Thanksgiving all over again.
A leftover Thanksgiving Casserole is delicious and economical! I hate to see any of the dishes I make for Thanksgiving go to waste. It takes a lot of time, energy, and money to put on a Thanksgiving dinner, and throwing any of it out is not an option at my house!

If you still have leftovers after making this casserole, then here’s another delicious idea for leftovers that my family loves. We call them Pilgrim Sandwiches or “Bobbies” because that is what they are called at Capriotti’s, one of our favorite sandwich shops. The ingredients are used straight from the fridge, so the turkey sandwiches are cold. If you prefer to heat the ingredients or broil the sandwich, that is good too.
Another great use for leftover turkey is to make a Turkey salad sandwich. Simply combine shredded leftover turkey with some mayonnaise (we like Best Foods and Hellmans) in a large bowl. Then add they turkey mixture to leftover rolls or croissants with some lettuce.
You can also use leftover turkey in recipes that call for chicken. Leftover turkey is delicious in our Homemade Chicken Noodle Soup and Chicken Pot Pie.

Notes
Variations to this recipe
Feel free to use whatever leftovers you have on hand. It doesn’t have to be exactly the same as what is listed here. Some ideas to try:- Substitute rice for mashed potatoes.
- Substitute peas, carrots, or green beans for corn, or use more than one vegetable depending on what you have on hand.
- Substitute croutons or bread crumbs for the topping if you don’t have stuffing leftovers.
Loved it. Simple and quick and delicious. The only thing I made twice the recipe and used a 9×12 glass pan rather than an 8×8. It fit perfectly.
I love this recipe, it’s one of the best. Thank you so very much ❤️.
Do you have any suggestions for freezing this?
I love the Boise area a lot, I lived in Garden Valley for a short while while on a sabbatical and did my shopping in Boise.
Thanks again for your recipes.
Thank you for your comment, Carrie! I’m so glad you like the Thanksgiving Casserole. It is so perfect for leftovers! I’ve never tried freezing it. The mashed potatoes don’t freeze well. The turkey, stuffing, and cranberry sauce all freeze well, so I would recommend freezing those separately then adding fresh mashed potatoes. The Boise area is beautiful – Emily and Erica live in the area and I visit all the time.
Very good! We plan to make this again. We were skeptical but were happily surprised after trying it!
I can’t rate because just made it and we haven’t tried it. Can it be made a day ahead and stored in fridge until baking time?
Yes, add a few minutes to the baking time to adjust for it being cold when placing it in the fridge. Check the center of the casserole to make sure it is warmed through before serving. Thanks for asking. Merry Christmas!
30 minutes is not long enough to heat the casserole. The time needs to be 1 hour
Over many years I’ve also made a very similar casserole, but serve the cranberries separately because some family members dislike them. The left-over casserole is so delicious and I plan on making it again this holiday season. My question is: How safe is it to freeze this casserole, and for how long?
We haven’t tried freezing this casserole, so I am not sure!
My favorite casserole ever, the cranberry sauce is unexpectedly the key, delicious ingredient that ties it all together!!
Made This last year and making it again this year amazing recipe must try!!!!
I tried this recipe last year, and it was so good, I cooked everything from scratch again, just to make the casserole! This is now my weekend after Thanksgiving must do that I look forward to eating for months. I substitute green bean casserole for the corn. Oh my, it’s tasty!
A great way to use the leftovers!! I doubled the recipe and it was delicious! Love the one dish, easy to bake and not lots of pots to clean. Thanks for posting!
HAHA…… after Thanksgiving we put all the side dish leftovers in the frig in their serving or casserole dishes, so after I put this together, I had a whole sink of Thanksgiving dishes to do! It is a great way to use up the leftovers.
I make this every year. It even appeals to my husband and two kids who are very picky.
I have made this several times. It is excellent. In fact, this year I’m not having Thanksgiving at my house but I will get a Rotisserie Chicken and make small batches of potatoes, stuffing, and cranberry sauce just so I can make this recipe!
Has anyone tried using sweet potato casserole instead of mashed potatoes?
Well I did tonight made 2 one with sweet potatoes and one with regular. If you don’t hear back it was amazing!!!!
Yes! Using leftover Marshmallow Sweet Potato Casserole is just Fabulous!
Has anyone tried green bean casserole as your vegetable.
Yes, and it’s fabulous! I don’t like corn, but I love green bean casserole.
LOVE this recipe! Such a great idea! I also had leftover cranberries, and fried onions leftover from our green bean casserole, so I sprinkled some of those in a corner to try it out, and we loved it!
I’ve been wanting to make an
“Everything But the Kitchen Sink Thanksgiving Casserole” for years. I made this last night. It is quick and easy! Would of liked for it to hold up better when I served it. But that aside, why isn’t Thanksgiving dinner served like this!!! So happy I found your recipe. I’ve already added this to my TG recipes. 😊
This was a hit this year! 2020 was a letdown but this recipe made everyone happy! This was the first time, I didn’t make a big deal of Thanksgiving dinner. My adult son, who doesn’t eat leftovers, took leftovers home! Thank you!
This is a great recipe! It’s not only super delish, but also customizable. I like to make it with either green beans or mixed veggies, and I’ve also made it any old time of the year with chicken. We like whole berry cranberry sauce, so that’s what I use. I double the recipe, & bake it in a 13″ X 9″ Pyrex (we like the leftovers). Thanks ladies 🙂
It is now a tradition to make at least 2 of these for Thanksgiving every year. It’s just my spouse and I, and we don’t like fussing with big fancy meals and all those dishes. We actually just make and eat this FOR Thanksgiving and throughout the whole weekend. We use turkey breast cooked right in the dish, add green beans in with the corn, and because we aren’t picky we use those packets of instant mashed potatoes, stovetop stuffing, and gravy in a jar. It’s super easy, quick, hardly messy, hassle-free, and DELICIOUS. It’s honestly great at any time of year. We also altered the recipe and sometimes use ham and spiced applesauce in place of the turkey and cranberry sauce. 10/10
I 💖 your idea! I too have been using boxed dressing mix for years. I dress it up though by sautéing a bunch of onions and celery – often oil-free in the microwave, adding it to the box mix with boxed chicken (or turkey if I can find it) stock. Makes it taste more like homemade. And I always do extra onions and celery so I can make another box (or 2 lol) for me as I send the leftovers home with the friends that I celebrate with.
Stay safe. Alberta, Canada 🇨🇦 where it’s currently 7°C (44°F) at my house. Brrr!
Best way to eat leftovers! Can’t wait for the day after Thanksgiving!
This is the perfect way to use holiday leftovers, it really is easy and delicious! We really enjoyed this casserole!
What can I use to replace the cranberry sauce?
I don’t know of a good substitute for cranberry sauce. You can omit it from the recipe if you prefer.
The tartness of the cranberry sauce balances the entire dish, so you could use anything that would do the same. Try experimenting with different fruits (such as cherries or spiced pears), a thicker vinegar-based sauce, or even some sort of mustard.
I have used Grape Jelly (but didn’t care for) and Lingonberry jam as a cranberry substitute.
All I have is jellied cranberry sauce. I guess that wouldn’t work would it? This recipe sounds delicious.
I think that would work!!
I don’t like cranberry sauce. What can I use instead?
There isn’t really a substitute for the cranberry sauce. You can just omit it if you don’t like it. It shouldn’t affect the recipe.
I used leftover spinach dip with water chestnuts in it. This gave the recipe a nice crunch. Part of my family do not like the sweet/salty taste. I put a divider made out of foil and bake both. Half had cranberry the other with spinach dip. This was a huge success… thank you

I would think you could substitute a jam, jelly or preserve. You need something sweet to hit all the flavors.
Everyone loved this.
It was great and used up all the thanksgiving leftovers.🦃
This recipe saved the day when I had uneven quantities of leftovers for a “Thanksgiving Round II” gathering. The effort to rave reviews ratio earns it a spot in the “make it next year” recipe stack!
Would chicken work with this? Inuave no turkey but have the rest!!..?
Yes, chicken would be delicious in this recipe!
Trying this today! I used Mac & cheese instead of mashed taters!
I followed the largest measurements for most of the ingredients. I didn’t have corn so I used 1 can of unsalted french cut green beans (drained). I only used 1 1/2 cups of gravy. Baked it covered for 30 mins and removed foil to bake uncovered for another 30 mins. I had wetter stuffing so I wanted to dry it out a little since there were other liquids in this casserole to keep it moist. This is so good! I almost prefer this to the actual dinner where everything is eaten separately LOL! Thanks for sharing. A keeper for sure.
I’m so glad you enjoyed it! Thanks for the 5-star rating!!
Can you freeze this and if so when you’re ready to make it can you just pop it in the oven from the frozen state?
I haven’t tried it that way before, but I think it would work! Let us know if you try it!
Just made this and it is absolutely delicious!! It has a sweet/salty quality to it that makes it crave—worthy! Sharing this recipe with my sister immediately!
LOVE this! Did it last year and doing it tomorrow! Happy Holidays!
Im looking forward to making this but I don’t have any leftover mashed potatoes. Do you think I should make mashed potatoes with butter or just mash and spread some boiled potatoes since the other ingredients are so rich?
I never say no to butter! 🙂 I think mashing them as you normally would, with butter, gives them a better consistency.
Hey there!
Just made your turkey leftovers casserole and put it in the freezer.
Looking forward to enjoying it in a month or so.
Thanks for the recipe!
Blessings,
Tori
