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 and today I decided to add a “Christmas Leftover” recipe into the mix, as I began to think about all of the turkey, ham, 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!

Mine has been with me to numerous parties, on several news appearances and even on a picnic!

Order one today, and one will be donated to a family in Africa, because after all, sharing is caring 🙂

Top with the basil pesto and bacon.

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.
