Main Ingredients

  • 2 cups dried green lentils (sorted & rinsed)
  • 8 cups vegetable stock
  • 2 stalks celery (small diced)
  • 4 medium carrots (small diced)
  • 1 medium onion (small diced)
  • 1 shallot (small diced)
  • 3 garlic cloves (minced)
  • 1 14-oz can fire roasted petite diced tomatoes
  • 1 dried bay leaf
  • 1/2 tsp dried thyme
  • 1 tsp ground cumin
  • 1/2 tsp smoked paprika
  • 1/4 tsp cayenne pepper (or to taste)
  • 1/2 tsp ground black pepper
  • 2 tsp kosher salt
  • 9 oz bag fresh spinach (roughly chopped)
  • 1 tbsp red wine vinegar

Instructions

  1. Prepare Ingredients: Sort and rinse the dried green lentils under cold water. Dice the celery, carrots, onion, and shallot into small pieces, and mince the garlic cloves.
  2. Add to Slow Cooker: In a 6-quart or larger slow cooker, combine the green lentils, vegetable stock, diced celery, carrots, onion, shallot, minced garlic, fire roasted petite diced tomatoes, dried bay leaf, dried thyme, ground cumin, smoked paprika, cayenne pepper, ground black pepper, and kosher salt. Stir to mix all ingredients evenly.
  3. Slow Cook the Soup: Cover the slow cooker and cook on low for 7 to 8 hours or on high for 3 to 4 hours. This slow cooking allows the lentils to become tender and the flavors to develop deeply.
  4. Prepare for Final Touches: About 15 minutes before the soup finishes cooking, carefully remove the bay leaf from the slow cooker. Then add the roughly chopped fresh spinach and the red wine vinegar to the soup. Stir well to combine.
  5. Wilt the Spinach: Allow the soup to continue cooking for another 10 to 15 minutes so the spinach can wilt properly, enhancing the soup with fresh green color and nutrients.
  6. Serve: Spoon the hot soup into bowls, and optionally top with freshly ground black pepper or grated Parmesan cheese for added flavor and richness.
  7. Enjoy: Serve warm and enjoy a nutritious, comforting lentil and spinach soup perfect for any day.

Notes

  • Adjust the cayenne pepper according to your preferred spice level.
  • You can substitute fresh spinach with kale or Swiss chard if desired.
  • This soup freezes well; store leftovers in airtight containers for up to 3 months.
  • For a creamier texture, blend a portion of the soup before adding the spinach.
  • Use low-sodium vegetable stock to reduce sodium content.
