This sweet potato soup is silky-smooth and slightly sweet with a touch of fall spices. The addition of celery, onion and carrots make this sweet potato soup recipe flavorful and delicious.
In a large stockpot or Dutch oven, melt the butter. Then add onions, celery, and carrots and cook over medium-high heat until the onions become translucent.
Once sweet potatoes are soft, transfer the contents of the pot to a high-powered blender, or use an immersion blender, and blend for 60 seconds or until completely smooth.
