Ingredients

Scale

Main Ingredients

  • 1 pound dried black beans
  • 1 medium onion, diced
  • 1 medium red bell pepper, cored, seeded, and diced
  • 3 cloves garlic, minced
  • 6 cups low-sodium vegetable broth
  • 1 1/2 tablespoons chili powder
  • 1 tablespoon ground cumin
  • 2 teaspoons kosher salt
  • 2 bay leaves
  • 1/2 teaspoon freshly ground black pepper

Optional Toppings

  • Fresh cilantro leaves and stems
  • Chopped avocado
  • Greek yogurt

Instructions

  1. Combine Ingredients: Place the black beans, diced onion, diced red bell pepper, minced garlic, low-sodium vegetable broth, chili powder, ground cumin, bay leaves, kosher salt, and freshly ground black pepper into a 6-quart or larger slow cooker. Stir everything together until evenly mixed.
  2. Slow Cook the Soup: Cover the slow cooker with the lid and cook on the LOW setting for 8 to 10 hours, or until the beans are tender and the flavors are well developed. Do not remove the lid during cooking to maintain the heat and moisture.
  3. Finish and Serve: Once the beans are tender, carefully remove the bay leaves from the soup. Ladle the soup into bowls and serve with your choice of optional toppings such as Greek yogurt, fresh cilantro, or chopped avocado for added freshness and creaminess.

Notes

  • Storage: Store any leftovers in an airtight container in the refrigerator for up to 5 days or freeze for up to 3 months to preserve freshness and flavor.
  • Soaking Beans: For quicker cooking, you can soak the dried black beans overnight and reduce cooking time to about 4-6 hours on LOW.
  • Spice Level: Adjust chili powder to taste for desired heat level.
  • Vegetable Broth: Use low-sodium broth to control the salt content in the soup.
