Easy Mashed Potato Soup Recipe
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.
I just 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, I like chunks of potatoes in my soup).
If you’d like an extra smooth mashed potato soup, you can toss it in a blender – and with some blenders, you can just 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 me! This is a super 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!
