Ingredients

  • 1 bag 16 oz Brown Lentils, rinsed
  • 8 cups Vegetable Stock
  • 1 can 15.5 oz Fire Roasted Diced Tomatoes
  • 2 medium White Potatoes diced
  • 2 large Carrots sliced
  • 1 stalk Celery sliced
  • 1 large White Onion diced
  • 1/2 tsp Salt
  • 1/4 tsp Black Pepper
  • 2 cups Fresh Kale chopped

Instructions

  • Assembly: Add the rinsed lentils, vegetable stock, fire-roasted tomatoes, diced potatoes, carrots, celery, onion, salt, and pepper to the crock pot.
  • Stir: Give the ingredients a good stir to ensure the spices are distributed.
  • Slow Cook: Cover and cook on low for 6–7 hours.
  • Add Greens: About 15 minutes before serving, stir in the chopped fresh kale.
  • Final Simmer: Continue cooking for 15 minutes or until the kale reaches your desired level of tenderness.
  • Serve: Ladle into bowls and enjoy warm.

Notes

  • Rinse Your Lentils: Always rinse your dry lentils in a fine-mesh sieve and check for any small stones before adding them to the pot.
  • Potato Choice: White or Yukon Gold potatoes hold their shape well in the slow cooker; Russet potatoes will break down more and thicken the soup further.
  • Acid Balance: For an extra pop of flavor, stir in a tablespoon of lemon juice or balsamic vinegar just before serving to brighten the earthy lentils.
  • Freezing: This soup freezes beautifully! Store in airtight containers for up to 3 months for an easy "instant" meal.
