Ingredients
  

  • 1 pound dried 15 bean mix
  • 8 cups water or vegetable broth
  • 1 large yellow onion finely chopped
  • 3 cloves garlic minced
  • 2 bay leaves
  • 1 teaspoon dried thyme
  • 1 teaspoon dried oregano

  • Optional: 1–2 cups chopped ham or smoked sausage
  • Optional: 1 cup chopped carrots
  • Optional: 1 cup chopped celery
  • Optional: 1 tablespoon hot sauce
  • Fresh parsley for serving

Method
 

  1. Sort beans and remove debris. Rinse thoroughly under cold water.
  2. Place rinsed beans in crock pot. Add broth or water, onion, garlic, and bay leaves.
  3. Add thyme, oregano, and smoked paprika. Add optional meats and vegetables if using.
  4. Pour in diced tomatoes with liquid and gently stir to combine.
  5. Cook on LOW 8–10 hours or HIGH 4–5 hours without lifting the lid.
  6. Stir in lemon juice during the last 30 minutes. Adjust seasoning with salt and pepper.
  7. Remove bay leaves and serve with fresh parsley.

Notes

Wait to add salt until the end of cooking—adding it early can prevent beans from softening properly.
