  • Total Time: 5 hours 5 minutes
  • Yield: 6 servings

Ingredients

  • 1 medium onion, diced
  • 3 carrots (about 1 cup), diced
  • 4 celery ribs, diced
  • 4 cloves garlic, minced
  • 1 cup green beans, cut into 1-inch pieces (fresh or frozen)
  • 1 can (28 ounces) crushed tomatoes
  • 1 pound baby potatoes, diced
  • 1 ½ cups dried brown or green lentils
  • 2 teaspoons paprika
  • 2 teaspoons oregano
  • 1 teaspoon thyme
  • 1 teaspoon cumin
  • 1 teaspoon coriander
  • 8 cups chicken or vegetable broth (plus more as needed)
  • Optional: 2 handfuls of baby spinach or kale
  • Mineral salt and black pepper, to taste
  • Juice of 1 lemon
  • 1 cup chopped Italian parsley

Instructions

  1. Add ingredients to the slow cooker: In the slow cooker, combine all ingredients except for the optional greens (spinach or kale), lemon juice, parsley, salt, and pepper.
  2. Cook the soup: Stir everything together until well combined. Cover with the lid and set the slow cooker to cook on HIGH for 4-5 hours or on LOW for 8-10 hours.
  3. Add greens: About 5 minutes before the soup is done, stir in the optional spinach or kale, and let them wilt.
  4. Season and finish: Season the soup with salt and pepper to taste. Squeeze the juice of 1 lemon into the soup and give it a final stir.
  5. Serve: Ladle the soup into bowls and garnish each serving with fresh chopped parsley. Serve hot, and enjoy! This soup pairs wonderfully with homemade vegan cornbread, vegan naan, or artisan bread.

Notes

  • For a thicker soup, use an immersion blender to blend part of the soup once it’s done cooking.
  • Store leftovers in an airtight container for up to 3 days, or freeze for up to 3 months.
  • You can substitute the baby potatoes with sweet potatoes for a sweeter flavor.
