Serving Size

4-6 servings

The southwest spice of chili and lime make this soup a smash hit.


  • 2 Tbsp (30 mL) butter
  • 2 cloves garlic, minced
  • 1 medium onion, chopped
  • 1-1/2 tsp (7 mL) chili powder
  • 3 cups (750 mL) reduced-sodium vegetable or chicken broth
  • 5 cups (1.25 L) cubed peeled sweet potatoes, (about 2 large)
  • 1-1/2 cup (375 mL) milk
  • 1-1/2 tsp (7 mL) cornstarch
  • 3/4 cup (175 mL) plain yogurt (not fat-free), divided
  • 1/4 tsp (1 mL) salt
  • pepper
  • 1 tsp (5 mL) grated lime zest
  • 2 Tbsp (30 mL) freshly squeezed lime or lemon juice


1. In a large pot, melt butter over medium heat. Add garlic, onion, and chili powder; sauté for about 5 minutes or until soft. Add broth and sweet potatoes; bring to a boil. Reduce heat and simmer until potatoes are soft, about 20 minutes.
2. Transfer to blender or food processor, in batches, or use an immersion blender in the pot, purée until very smooth, adding some of the milk if necessary to thin. Return soup to pot, if necessary. Stir in milk and salt. Heat over medium heat, stirring, until steaming, but do not let boil.
3. In a small bowl, whisk cornstarch into 1/2 cup (125 mL) of the yogurt. Stir into soup; heat, stirring, for 1 minute. Stir in salt and season to taste with pepper. Stir lime zest and juice into the remaining yogurt. Ladle soup into warmed bowls; dollop lime yogurt on top of each serving.

  • Sweet potatoes are often mislabeled as yams (true yams are quite different).
  • Choose sweet potatoes with tight, brick-colored skin with no signs of wrinkling or mold, and feel heavy for their size.
  • The flesh should be firm, moist, and bright orange.
  • Use ancho chili powder in place of regular chili powder.
  • Add 2 tbsp (30 mL) unsweetened peanut butter with the sweet potatoes; sprinkle chopped peanuts and chopped fresh cilantro on top of the yogurt.
