Ingredients

  • 1 tablespoon avocado oil or unsalted butter
  • 1 medium yellow onion chopped
  • 1 teaspoon ground cumin
  • 1 teaspoon paprika
  • 1 teaspoon salt
  • ¾ teaspoon pepper
  • ½ teaspoon garlic powder
  • 3 large sweet potatoes peeled and chopped
  • 2 red bell peppers de-seeded and chopped
  • 5-6 cups vegetable broth or chicken broth (see Recipe Notes below)
  • ½ cup heavy cream (optional)

Optional Garnishes:

  • Fresh parsley finely chopped
  • Sour cream or plain Greek yogurt

Instructions

  • Sauté Vegetables: In a large soup pot, heat avocado oil or butter over medium heat. Add chopped onion and sauté until translucent, about 5 minutes, stirring occasionally.
  • Add Spices: Add ground cumin, paprika, salt, pepper, and garlic powder to pot. Stir, then sauté until fragrant, about 30 seconds.
  • Add Sweet Potatoes and Bell Peppers: Add chopped sweet potatoes and red bell peppers to pot. Stir to combine with onion and spices.
  • Pour in Broth: Add 6 cups of broth to the pot (if you'll be using a blender instead of an immersion blender to blend the soup after cooking, start with 5 cups and see note below). Increase stovetop heat to high and bring mixture to a boil (this may take 10 to 15 minutes).
  • Simmer: Reduce stovetop heat to low and simmer soup uncovered until sweet potatoes are tender, about 20 to 25 minutes.
  • Blend Soup: Use an immersion blender to puree the soup directly in the pot until smooth. Alternatively, carefully ladle soup into a blender or food processor, and, in batches, blend until just smooth (do not over-blend), and then return to the pot (you may need to do this in batches, depending on the capacity of your blender).
  • Add Heavy Cream (Optional): If you want a creamier soup, pour in heavy cream, then stir.
  • Add Additional Seasoning: Carefully taste soup and, based on preferences, add more salt and pepper.
  • Garnish and Serve: Ladle soup into bowls and garnish with sour cream or Greek yogurt and chopped parsley, then serve.

Notes

If Using a Blender Instead of an Immersion Blender: I have found that using an immersion blender yields a thicker soup than if you blend with a blender. If you’re going to blend the soup with a blender, use only 5 cups of broth to start with. Then, after blending, if you want to thin the soup out a bit, you can always stir in an additional 1 cup of broth before adding in the heavy cream.
Storage: Store the soup in an airtight container in the fridge for up to 4 days or in the freezer for up to 2 months. If frozen, thaw in the refrigerator overnight before reheating.
Reheating Instructions: Transfer the soup to a saucepan and warm on medium heat on the stovetop until heated through. Or, microwave in 30-second increments, stirring after each time, until heated through.
