Slow Cooker Leftover Thanksgiving Casserole

  • Cooking Time:

    2-3 hours on HIGH
  • Servings:



3 cups prepared stuffing
1/2 cup whole berry cranberry sauce
1 lb. cooked turkey (about 4 cups)
Add any leftover vegetables too!
1 cup mayonnaise
1/2 cup grated Parmesan cheese
1 1/2 cups mashed potatoes
1/4 cup Italian seasoned bread crumbs

Happy Holidays! Yes, it’s that time of year when we tend to over-indulge. If you are like my family, we always make way too much food and have tons of leftovers. I’m not complaining at all – they are just as good the next day! A few years back we started getting creative and ran across a recipe for Thanksgiving Casserole – the yummiest, tastiest thing to make with all those leftovers. Sometimes we have additional ingredients to throw in like green beans, peas and corn! I hope you enjoy it as much as my family. What are your holiday traditions?

  1. Grease a 4-5 Quart Slow Cooker with non-stick cooking spray.
  2. Place prepared stuffing in the crock.
  3. Next, layer cranberry sauce followed by turkey.
  4. Optional: Add any leftover vegetables you would like to add
  5. In a separate bowl, mix mayonnaise and cheese.
  6. Spread half of the mayonnaise mixture over top of the turkey.
  7. Spread mashed potatoes on top of the mayo mixture.
  8. Evenly spread the remaining mayo mixture on top of potatoes and then sprinkle with bread crumbs.
  9. If desired, place a paper towel over top of the crock before placing lid on top. (to absorb any moisture and prevent soggy bread crumbs.)
  10. Cover and Crock on HIGH for 2-3 hours or until heated through.
  11. Optional Step: Broil for 5 minutes in oven to brown the top of the casserole.

NOTE: For best results, your slow cooker should be about 1/2-2/3 full when cooking.  If it’s less than that you will need to reduce Crocking time.

Happy Crocking!

Thank you very much for posting this recipe for the thanksgiving leftovers!! I was just checking various websites for a good easy recipe to use the remainder of our thanksgiving leftovers but didnt find any recipes that really suited my fancy. This recipe sounds perfect and so easy. Everyone around the house is getting so tired of the same old thing every day and turkey sandwiches. Lol. Thank you thank you thank you!!

I would like to make this tomorrow but absolutely cannot stand mayo…could I substitute sour cream or maybe ranch dressing in it’s place? or can you even taste the mayo?

You can also interchange plain yogurt for mayo. Also sour cream. May not make it as creamy but the flavor is good.

I have this cooking in my slow cooker right now and it smells divine…the only thing I did differently was substituted cream of mushroom soup for the mayo mixture…I do not like mayo at all and didn’t get a response back on time to get your opinion…hopefully it will turn out as great as it smells…:)
