Creamy Potato and Avocado Soup

Creamy Potato and Avocado Soup is the creamiest, most delicious potato soup you’ll ever make! Also a great way to use up those leftovers.


This soup was totally made by accident – and what a good accident it was.

I had made about 5 lbs. of mashed potatoes to try out a recipe idea I had and it bombed. Didn’t work out at all.

I can’t complain too much because that doesn’t really happen to us that often. But now what to do with the remaining 3lbs. of mashed potatoes??

Just eat them – Christie said. That’s nothing for you and the boys to finish off at dinner time! Which is true, we could just eat them…

But I was still in recipe mode so I wanted to make something for the site here. What to do with leftover mashed potatoes? THere’s a ton of recipes, like our Fried Mashed Potato Balls, or our Loaded Skillet Mashed Potatoes. But I still wanted something different…Then I got it.

Soup! I’m going to take my leftover mashed potatoes and make creamy potato soup. Pretty smart, right? And to top that crazy smart idea all off I’m going to make it even better by adding avocados to the mix.

Avocado is one of my new favorite foods. I can’t believe that for years I didn’t eat them, thought I didn’t like them. So now we have avocados in the house all the time. Mostly for making guacamole but we use them in so many different recipes too.

But today it’s soup time – if you don’t happen to have mounds of leftover mashed potatoes I included our recipe for them incase you want to make that 5 lb. bag, have some mash for dinner and then make this soup with the rest. Or you can always half this recipe and make the soup with the amount of potatoes that you do have leftover.

Here we go –

Get your mashed potatoes into a big soup pot and add in one smashed up avocado.


Mix together.

Stir in 3-4 cups of chicken broth and heat until bubbling.


Creamy Potato and Avocado Soup.

Seriously easy. Seriously amazing. Also I want to add that the only cream in here is the 3/4 cup that we made the mashed potatoes with and if you’re counting calories you could easily substitute milk.

You can add some toppings or not- we had bacon so that was a no brainer. But it’s good all by itself, I promise.

I’m sure someone, somewhere has turned mashed potatoes into soup before but I’m not going to google it. For now it’s all my idea!
