Equipment

Ingredients

  • 1 pound dried brown lentils
  • 1 medium onion, diced
  • 2 medium carrots, sliced
  • 2 medium celery stalks, diced
  • 3 garlic cloves, minced
  • 1 teaspoon ground cumin
  • ½ teaspoon ground coriander
  • 8 cups vegetable broth
  • 1 (14.5 ounce/411 gram) can diced tomatoes
  • Salt and pepper, to taste

Instructions

  • Place the lentils, onion, carrots, celery, garlic, cumin coriander, and vegetable broth into a (3 quart or larger) slow cooker. Stir everything up, cover, and turn on the slow cooker. Cook the soup on high for 2 ½ to 3 ½ hours, or on low for 5 to 6 hours, until the lentils are soft and the vegetables are tender.
  • Stir in the tomatoes and let the soup cook for about 20 minutes longer, just to heat up the tomatoes.
  • Season the soup with salt and pepper to taste. Serve.
