  • 4 tablespoons butter, divided
  • 2 medium leeks (white portion only), finely chopped
  • 3 garlic cloves, minced
  • 4 cups cubed peeled sweet potatoes (about 1-1/2 pounds)

  • 1/2 teaspoon cayenne pepper
  • 5 cups vegetable stock
  • 2 cups heavy whipping cream

  1. In a Dutch oven, heat 2 tablespoons butter over medium heat; saute leeks and garlic until leeks are tender, 4-6 minutes.
  2. Stir in sweet potatoes, 3/4 teaspoon salt, cinnamon, cayenne and stock; bring to a boil. Reduce heat; simmer, covered, until potatoes are tender, 15-20 minutes.
  3. Puree soup using an immersion blender or cool slightly and puree soup in batches in a blender; return to pan. Stir in cream and 2 teaspoons thyme; bring to a boil. Reduce heat; simmer, uncovered, 5 minutes.
