Ingredients
  

  • 1 cup dried black beans soaked overnight and drained
  • 4 cups vegetable broth homemade or low-sodium
  • 1 medium onion roughly chopped
  • 3 cloves garlic roughly chopped or minced
  • 1/2 teaspoon cumin seeds toast before grinding
  • 1/2 teaspoon chili powder
  • to taste salt adjust as needed
  • fresh lime lime juice squeezed at the end
  • optional toppings sour cream, chopped cilantro, or sliced green onions

Equipment

  • Slow cooker
  • Immersion blender
  • Knife and chopping board
  • Measuring cups and spoons
  • Ladle

Method
 

  1. Rinse soaked black beans thoroughly and drain. Place them in the slow cooker along with chopped onion and garlic.
  2. Toast cumin seeds in a dry skillet over medium heat until fragrant, about 1 minute, then grind them into a powder and add to the slow cooker.
  3. Pour in the vegetable broth and stir in chili powder. Cover the slow cooker and cook on low for 8 hours until the beans are tender and starting to break apart.
  4. Once cooking is complete, use an immersion blender to blend part of the soup directly in the crockpot until smooth, or transfer half to a blender, blend until creamy, then return to the pot.
  5. Stir in freshly squeezed lime juice, taste, and adjust salt as needed. The soup should be thick, velvety, and fragrant with smoky spices.
  6. Ladle the hot soup into bowls and top with your favorite toppings like sour cream, chopped cilantro, or sliced green onions for freshness and contrast.

Notes

Soaking dried beans overnight improves texture and flavor. Toast spices for a deeper smoky aroma. Pureeing part of the soup creates a velvety finish, but you can leave it chunky if preferred. Add lime juice at the end for brightness. Adjust seasoning carefully, tasting as you go.
