A Delicious Way To Use Leftover Mashed Potatoes

This soup was totally made by accident – and what a good accident it was. I had made about 5 pounds 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 three pounds of mashed potatoes??

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.

How Do You Make This Creamy Potato Soup?

But today it’s soup time – if you don’t happen to have mounds of leftover mashed potatoes I included our recipe for them in case you want to make that 5 pound bag. Or you can always half this recipe and make the soup with the amount of potatoes that you do have leftover.

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

Stir in 3-4 cups of chicken broth and heat until bubbling. This Potato and Avocado Soup is so comforting, our boys go crazy for it!

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!
