  • You can also use bay leaves in the soup. Just make sure to remove them after the cooking time.
  • Baby spinach is also great in this soup. Feel free to toss in a handful of leafy greens after the quick release. It is a great way to get kids to eat it. Kale is also delicious. You can use the one you prefer.
  • Other Vegetables. Zucchini, Bell peppers, sweet potato, and other veggies are great in this lentil soup.
  • Toppings are delicious on this soup. Try grated Parmesan, bacon or a dash of lemon.
  • Add meat. This soup is tasty with ground sausage. Just brown the sausage first and then add the other ingredients. Another option is cooked diced ham. Add this after the soup has cooked for a great way to use leftovers.
  • Change the Lentils. You can substitute red or green lentils in this soup.
  • Red Pepper Flakes. If you like soup with a little heat, sprinkle red pepper flakes into the soup.

Serving Suggestions

You might also want to try grating parmesan cheese on top. The kids also like to crumble bacon on their soup.

Vegetarian Variation

Substitute vegetable broth for the chicken broth in the recipe. This is a simple recipe to make this soup vegetarian if needed.

I recommend using a low sodium vegetable broth. This is one of the easiest and tastiest vegetarian soup recipes. This is also naturally a gluten-free recipe.

    Super simple and tasty. The only change I made was to add a little red wine vinegar at the end. Yum!

    On the menu for later this week. FYI – I read celery above but I think you forgot to list it in the recipe.

  4. Percola H says:

    This sounds delicious, and I will be trying it tomorrow, because I have a bag of lentils in my pantry that I don’t know what to do with.
