Spicy sausage makes this a hearty lentil soup. Use chicken and apple sausage, andouille, or your own favorite smoked sausage in this soup.

This makes a big batch of soup for a big family or party, or freeze a batch for later.


  • 1 pound lentils
  • 1 cup diced celery
  • 1 cup diced onion
  • 1 cup diced carrot
  • 2 cloves garlic (coarsely chopped)
  • 12 ounces​ smoked sausage (chicken,​ andouille, turkey sausage, or other)
  • 6 cups​ chicken broth
  • 2 cans (14.5 ounces each) diced tomatoes (undrained)
  • 2 cups chopped fresh spinach (or Swiss chard or kale)
  • Juice of 1 lemon (about 2 tablespoons)
  • 1/4 teaspoon ground black pepper
  • 1 tablespoon chopped fresh parsley
  • Salt (to taste)

Steps to Make It

  1. Rinse the lentils and drain them thoroughly.

  2. Combine all ingredients, except salt, in a 5 to 7-quart slow cooker.

  3. Cover and cook on LOW for 6 to 8 hours, until lentils and vegetables are tender.

  4. If desired, puree some of the soup in a blender to thicken. Or, use an immersion blender and blend until you reach the consistency you desire.

  5. Taste and season with salt, as needed.

Use Caution When Blending Hot Ingredients

Steam expands quickly in a blender, and can cause ingredients to splatter everywhere or cause burns. To prevent this, fill the blender only one-third of the way up, vent the top, and cover with a folded kitchen towel while blending.
