Mashed Potato Soup

With Thanksgiving coming up, it's time to start thinking of ways to use up all those leftovers.

We always have a lot of meat leftover, but somehow it seems like our mashed potatoes have a mind of their own and reproduce like a ton of bunnies.

Seriously- how is it we always end up with a metric ton of spuds?

We make SO many, and have SO many mashed potato leftovers – we needed to come up with a good recipe to use up mashed potatoes.

There's only so many times you can eat the same thing- so this Easy Slow Cooker Leftover Mashed Potato Soup recipe is one of our favorite ways to make a new meal out of leftover mashed potatoes.

This recipe is so great because there is virtually no prep and doesn't involve any fancy equipment- making this a great hearty soup you can make without feeling drained the day after a big meal.

We toss everything in the slow cooker and then use an immersion blender to smooth the soup out when it is ready to serve, if needed (which is rare, we like chunks of potatoes in our soup).

If you'd like an extra smooth mashed potato soup, you can toss it in a blender – and with some blenders, you can keep whirring it until piping hot.

10 Minute Leftover Mashed Potato Soup Recipe

Who wants to slave away in the kitchen after all the work of Thanksgiving?

Not us! This is a easy soup that will keep you out of the kitchen, but give you something hearty and warm to share with your family.

If you try this recipe and like it- and want to try a variation- try cream of mushroom soup or cream of chicken soup instead of the cream!

This recipe can be made in under 10 minutes with these easy tips and tricks:

If soup is too thick, add in more heavy cream or whole milk.

Add more flavor with bacon crumbles or up to 1/2 cup of grated parmesan cheese.

Add garlic powder for a savory kick nobody can resist.

Lay out toppings – like shredded turkey, crispy bacon bits, flash fried onions, fritos, chives, or shredded cheddar cheese to top soup with.

You would also sub out some broth and add more mashed potatoes if you'd like a soup that isnt as thick.

Or add in some carrots and celery and then blend the soup before serving to sneak in some veggies!
