Cheesy Turkey Potato Soup

Cheesy Turkey Potato Soup is a delicious and hearty meal that makes good use of both your leftover turkey and mashed potatoes.
Is your fridge like mine and still full of your Thanksgiving leftovers? Right after the holiday, we usually just recreate our holiday meal with the leftovers. But, after a couple days of that it’s time to get a little creative with the leftovers.
I always find soup to be a really good way to use leftovers from my holiday meal. Soup is such a flexible dish that you really can’t go wrong with it. I love soups that are nice and creamy, so this potato turkey soup was perfect for my leftover turkey and mashed potatoes.
But how did it taste? This soup turned out so creamy and cheesy, my whole family loved it.
It was full of flavor and so hearty. All you need to turn this into a complete meal is to add some bread or a tossed salad.
Leftover mashed potatoes were a great way to thicken the soup and make is nice and creamy. Plus it added great flavor. To make sure the soup had nice texture, I added diced potatoes which also added more flavor, along with carrots, celery and onion.
The final touch to make this soup totally delicious was to add some flavorful sharp cheddar cheese, which also added to the silky texture. Make this soup and you won’t even feel like you’re eating leftovers.

This is perfect! I am making this tonight to finally be done with my leftovers!!! Thanks for the recipe. 🙂
You’re welcome, Aubrey! Enjoy!! 🙂
I made this for dinner tonight to put our Thanksgiving leftovers to bed, and it was FABULOUS !And I was ready to pitch them. I only had 2 cups of mashed potatoes so I threw in what was left of the dressing (about a cup), and that worked great. I was tempted to garnish with leftover cranberry sauce (sounded good to me), but held off. Maybe at lunch tomorrow. Thanks for this wonderful recipe; I’ll be making it with Christmas leftovers too!
I’m so glad to hear you enjoyed this, Susan! That was a great idea to throw your leftover dressing in, I’ll need to try that next time! 🙂
I just found you at Taste and Tell Thursdays. This is such a great way to use up those left overs, and I love that you added mashed potatoes to thicken the soup.
Thanks for stopping by Kari! The mashed potatoes worked out great in this soup and my son who initially turned his nose up when I told him what was for dinner, ended up eating two bowls! So I’d say it was a hit!!
Oh I love that you used leftover mashed potatoes in your soup. It looks fantastic and the cheese just sends it over the top. Thanks for sharing on Thursdays Treasures.
My motto is everything’s always better with cheese! 🙂
Oh Lisa! This is AWESOME!! I am sharing this to my page and I am so making this! TY so much for sharing.
Can you freeze leftovers?
Yes! You can definitely freeze the leftovers.
Thank you!
I replaced the cheddar cheese with Asiago, added the left over corn and a half a cup of white mushrooms. The soup was fantastic! Thanks for the recipe!
I’m so glad you enjoyed the soup! The changes you made to the recipe sound delicious! I’m definitely going to add mushrooms next time I make this!
