Ingredients

  • 1 package (about 1 lb) 15 bean mix, rinsed and sorted
  • 8 cups vegetable broth
  • 1 large onion, diced
  • 3 cloves garlic, minced
  • 2 medium carrots, peeled and diced
  • 2 celery stalks, diced
  • 1 can (14.5 oz) diced tomatoes, undrained
  • 1 tsp smoked paprika
  • 1 tsp ground cumin
  • 1 tsp dried oregano
  • 1/2 tsp black pepper
  • 1/2 tsp crushed red pepper flakes (optional for heat)
  • 2 tbsp tomato paste
  • 2 bay leaves
  • Salt to taste
  • 2 tbsp olive oil
  • Fresh parsley or cilantro for garnish (optional)

Equipment

  • Slow cooker or crock pot (6-quart or larger recommended)
  • Cutting board and knife
  • Measuring spoons and cups
  • Wooden spoon or heatproof spatula
  • Can opener
  • Colander or fine mesh sieve (for rinsing beans)

Instructions

  1. Sort and rinse the beans: Empty the 15 bean mix onto a large plate or tray and pick out any small stones or debris. Rinse the beans thoroughly under cold running water using a colander.
  2. Prepare vegetables: Dice the onion, carrots, and celery. Mince the garlic cloves and set aside.
  3. Sauté aromatics (optional): In a small pan, heat olive oil over medium heat. Add diced onion and sauté until translucent, about 4-5 minutes. Add garlic and cook for another minute until fragrant. This step adds depth but can be skipped if short on time.
  4. Combine ingredients in crock pot: Transfer the sautéed onion and garlic to the slow cooker. Add rinsed beans, diced carrots, celery, canned tomatoes (with juice), vegetable broth, tomato paste, smoked paprika, cumin, oregano, black pepper, crushed red pepper flakes, and bay leaves.
  5. Stir well: Mix all ingredients until the tomato paste is evenly distributed.
  6. Cook low and slow: Cover and cook on low for 8-10 hours or on high for 4-6 hours. The beans should be tender and the flavors well melded.
  7. Check seasoning and consistency: About 30 minutes before serving, stir the soup and taste. Add salt as needed and adjust seasoning if desired. If the soup is too thick, add a little more vegetable broth or water.
  8. Remove bay leaves: Before serving, fish out the bay leaves and discard.
  9. Serve and garnish: Ladle soup into bowls and garnish with fresh parsley or cilantro if desired. Enjoy warm!

Tips & Variations

Soaking the beans overnight can reduce cooking time and improve digestibility, but it’s not necessary when using a crock pot as it slowly softens the beans.

Feel free to add other vegetables such as diced potatoes, zucchini, or bell peppers for more variety. If you want a smoky flavor, add a splash of liquid smoke or a smoked sausage substitute for a vegetarian option.

For a creamier texture, stir in a few tablespoons of coconut milk or cashew cream before serving. You can also blend a portion of the soup and return it to the pot to thicken it up.

Spice lovers can amp up the heat with additional chili powder or cayenne pepper. If you like your soups chunkier, reduce the broth slightly.
