Garlic Basil Potato Soup Appetizers

‘Twas the week of Christmas and all through the house, there were dreams of turkey, mashed potatoes and brussels sprouts!

Ok, ok I promise not to continue,  but seriously I’m so excited for Christmas in 3 days and most importantly, Christmas dinner!

Garlic Basil Mashed Potato Soup

A month ago, I introduced a few “Thanksgiving Leftover” recipes on the blog, like Turkey Tostadas with Pomegranate Guacamole and Turkey Spinach Quiche with Stuffing Crust.

Today I decided to add a “Christmas Leftover” recipe into the mix as I began to think about all of the turkey, mashed potatoes and stuffing that will fill the fridge next week!

The great thing about this recipe is that while it’s a great use for leftover mashed potatoes, it’s actually super easy to make anytime you’re craving a big bowl of warm, creamy potato soup!

You can even serve it in little appetizer cups for parties or events, such as New Years Eve!

I whipped this recipe up in my Wonderbag, the portable slow cooking device that continues to cook food that has been brought to a boil without any additional fuel or electricity!

It’s great for taking to parties, and definitely an excellent conversation starter!

I also added a little fresh parmesan cheese, because I saw it in the fridge and it said, “I would be really delicious on that soup.” And I said “yes, you would.”

And yes, I do talk to my food… on a regular basis… lol.
