  • Stir in Parsley – 15 to 30 minute before serving stir in the parsley.
  • Serve and Enjoy – Serve warm and enjoy.

Can I Make this Soup on the Stove Top?

Yes, if you prefer to make this soup on the stove top, the process will still remain the same. Place all the ingredients in your dutch oven or in a large pot and cook the ingredients.

The soup will take about 30 minutes. Make sure to check if the lentils are done before serving. If they are hard, then the soup will need to cook a little longer.

If you are adding in spinach or kale, make sure to add it in the last 5 to 10 minutes so that it doesn’t overcook.

Recipe Variations:

  • Bay Leaf – We like adding in bay leaves to this soup. Just make sure to remove them after the cooking time.
  • Add Green Vegetables –  Feel free to toss in a handful of spinach 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.
  • Top the Soup –  Try grated Parmesan, bacon or a dash of lemon for added flavor to this soup.
  • 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.
  • Lentils – You can substitute red lentils or green lentils in this soup.
  • Red Pepper Flakes –  If you like soup with a little heat, sprinkle red pepper flakes into the soup.
  • Ham Bone – When I am making a soup with beans and I have a ham bone, I like to add it to the soup for added flavor.
  • Broth – If you want to make this a vegetarian dish, use vegetable broth instead of chicken broth.
  • Red Wine Vinegar – For an extra boost of flavor, add in some red wine vinegar or lemon juice. You can also add in balsamic vinegar or white vinegar.
  • Tomatoes – We used diced roasted tomatoes, but you can also use diced tomatoes or crushed tomatoes.
  • Dairy Free – This is soup is also dairy free. But I like adding cheese to the top, so omit that if you prefer it to be dairy free.

Tips for Lentil Soup:

  • Crock Pot: I love the programmable slow cooker for this soup that you can set for certain times. It makes busy days less hectic. I like to cook my soups on low so it cooks all day.
  • Crock Pot Liners: I recommend using liners for the slow cooker to make clean up super easy. You can just toss and go. I also like to oil the slow cooker with olive oil.
  • Food processor: Use a small food chopper or food processor to quickly and easily chop the onions and celery. Another time saving tip is to learn how to freeze onions.
  • Adding in Spinach – If you add in Kale or spinach make sure you add it close to the end of cooking time. This ensures that you do not over cook the spinach or kale.
  • Thickness – If the soup is too thick for your preference, add more broth to thin it out. You can also do this when reheating leftovers.
  • Lentils are Hard – If you lentils are hard after cooking, that usually means that they haven’t cook long enough.
  • Gluten Free – This soup is naturally gluten free.
  • Mashed Lentils – If you would like a thicker soup, you can mash some of the lentils with immersion blender. Then add them back into the soup.

What to Serve with Lentil Soup Crock Pot Recipe:

  • Homemade Bread – We love to serve this soup with homemade bread. It is great for dipping or to get the last drop of the soup.
  • Roasted Vegetables – You can also serve this roasted broccoli or roasted brussell sprouts for an easy side.
  • Salad – This soup is served perfectly with a kale salad or a broccoli salad.

This Lentil soup is easy to store the leftovers. Place the leftover soup in an air tight container. If stored properly the soup will last up to 5 days in the refrigerator.
