Home Chef Tips

  • If the soup thickens too much while cooking (or when you reheat leftovers), add extra broth or water to reach your desired consistency.
  • Make it vegetarian by swapping the chicken broth for vegetable broth, and using a plant-based sausage or omitting the sausage.

How To Serve Sausage Lentil Soup

If desired, top each bowl with a dollop of Greek yogurt, some fresh cilantro, a lime wedge for squeezing, and a side of naan bread.

Or heck, just keep it super simple and ladle this soup directly out of the crockpot, insert spoon, and call it a day. Either way, you’re going to love this recipe!
