  • 1 tablespoon olive oil
  • 1.5 pounds sweet potatoes peeled and chopped
  • 1 medium sweet onion chopped
  • 1 stalk celery chopped
  • 1 jalapeno pepper chopped
  • 2 cloves garlic chopped
  • 15 ounce can crushed tomatoes or equivalent fresh tomatoes
  • 1 cup vegetable stock
  • ¼ cup packed fresh basil leaves
  • 1 tablespoon Cajun seasoning blend or more as desired
  • Salt and pepper to taste
  • 1 cup plain yogurt
  • FOR SERVING: Lemon juice fresh chopped herbs, chili oil, chili flakes


  • Heat a large pot to medium heat and add the olive oil. Add the sweet potatoes, onion, celery, jalapeno and garlic. Cook, stirring often, about 10 minutes to soften everything up.
  • Add the remaining ingredients (except for the yogurt) and bring to a boil. Reduce the heat and simmer for about 20 minutes, until everything is nice and tender. You can simmer longer if you’d like.
  • Use a stick blender to process the soup until it is nice and smooth. Or, transfer the soup to a blender or food processor in batches to process, then back into the pot it goes.
  • Adjust for salt and pepper.
  • Swirl in the yogurt and stir until the soup is nice and creamy.
  • Spoon into bowls and swirl in juice from a quarter lemon per bowl.
  • Top with fresh herbs, chili flakes and a few drizzles of chili oil.


Makes 4 large bowls, about 2 quarts.
Heat Factor: Mild-Medium. You'll get big flavor without crazy heat using a single jalapeno and Cajun seasoning blend here. If you're looking for more heat factor, add in extra jalapenos and additional Cajun seasonings, or try more potent peppers. You can also use spicy chili flakes as well as chili oil for drizzling over the top.
