This is the kind of soup that you can't stop eating once you start. It's full of goodness and at the top of the line of comfort food. It's filling and that's the trouble. I want to eat more but don't have the room! Hope you enjoy this as much as we do.
In large stockpot, add broth, sweet potatoes, and onions together. Bring to a boil for about 30 minutes until sweet potatoes are tender. When they are tender, take a hand mixer and carefully mash the sweet potatoes right in the broth. When creamy, add butter and stir until blended. Add red pepper flakes. Stir. Add sour cream and stir. Add instant potatoes and whisk until blended. Add bacon bits. Salt and pepper to taste. Let soup sit a spell for all the flavors to blend together...about 15 minutes before serving.
NOTE: The prep time includes peeling the sweet potatoes, too.
