Ingredients

  • 2 tablespoons olive oil
  • 1 medium onion diced
  • 1 red bell pepper diced
  • 3 garlic cloves minced
  • 1 teaspoon ground cumin
  • 1 teaspoon chili powder
  • ½ teaspoon smoked paprika
  • ¼ teaspoon cayenne optional
  • 4 cups chicken or vegetable broth
  • 3 cups sweet potatoes peeled and cut into ½ to ¾-inch cubes(about 2 medium)
  • 1 15-ounce can black beans drained and rinsed
  • 1 ½ cups corn kernels fresh or frozen
  • 1 cup whole milk
  • 2 tablespoons cornstarch
  • ½ cup Greek yogurt
  • 1 teaspoon salt
  • ½ teaspoon black pepper
  • Juice of 1 lime
  • ¼ cup chopped fresh cilantro loosely packed plus extra for garnish

Instructions

  • In a large pot or Dutch oven over medium heat, add olive oil to heat.
  • Add onion and red bell pepper to the pot. Cook 5–6 minutes until softened.
  • Add garlic and cook 1 minute until fragrant.
  • Stir in cumin, chili powder, smoked paprika, and cayenne if using, toasting for 30 seconds until fragrant.
  • Pour in the broth, scraping up any browned bits. Add sweet potatoes.
  • Bring to a boil, then reduce heat and simmer 15–20 minutes, until sweet potatoes are fork-tender.
  • While the soup simmers, whisk the cornstarch into the whole milk in a small bowl or measuring cup until fully dissolved, with no lumps.
  • Add black beans and corn, then pour in the cornstarch-milk mixture. Return to a simmer and cook 3–4 minutes, stirring occasionally, until the chowder thickens slightly.
  • Remove the pot from heat. In a small bowl, whisk a ladle of the hot chowder into the Greek yogurt to temper it, then stir the mixture back into the pot. Stir in the lime juice, cilantro, salt, and pepper.
  • Taste and adjust seasoning.
  • Top with extra fresh cilantro before serving.

Recipe Tips

  • Take the pot off the heat and temper the Greek yogurt before stirring it in, so it doesn’t curdle.
  • Use low-sodium broth and add the salt at the end, since broths vary.
  • Use vegetable broth for a vegetarian chowder.
  • Leave out the cayenne for a mild version, or add 1 to 2 minced chipotles in adobo for more heat.
