Slow Cooker Sweet Potato Soup

I love that I can top this creamy soup with anything my heart desires, which means I can eat it several days in a row without ever having to have it the same way twice. You can substitute fresh onions and celery in this recipe if you prefer, but using the dried version makes it easy to throw together on a weekday morning. —Colleen Delawder, Herndon, Virginia
  • Total Time
    Prep: 15 min. Cook: 5 hours
  • Makes
    8 servings (2-1/2 quarts)

Ingredients

  • 3 pounds sweet potatoes, peeled and cut into 1-inch cubes (about 8 cups)
  • 2 tablespoons butter
  • 1 tablespoon Worcestershire sauce
  • 1 teaspoon dried minced onion
  • 1 teaspoon dried celery flakes, optional
  • 1/2 teaspoon salt
  • 1/2 teaspoon pepper
  • 1/4 teaspoon dried thyme
  • 1/8 teaspoon ground chipotle pepper
  • 6 cups reduced-sodium chicken broth
  • Optional: Sour cream and pepitas

Directions

  • In a 4- or 5-qt. slow cooker, combine all ingredients except sour cream and pepitas. Cook, covered, on low until potatoes are tender, 5-6 hours.
  • Puree soup using an immersion blender. Or, cool slightly and puree soup in batches in a blender; return to slow cooker and heat through. If desired, top servings with sour cream and pepitas.
    Freeze option: Freeze cooled soup in freezer containers. To use, partially thaw in refrigerator overnight. Heat through in a saucepan, stirring occasionally; add broth or water if necessary.


Test Kitchen Tips
  • Use 1 medium onion and 2 celery ribs, chopped, if you want to use fresh instead of dried.
  • If you prefer fresh herbs, use 3/4 tsp. minced fresh thyme in place of the 1/4 tsp. dried.
  • The potatoes will be tender in 5-6 hours, but they can be cooked longer since they'll eventually be pureed.
  • Chipotle pepper adds a touch of smoky heat, but it can be omitted.
