Ingredients
Substitutions
This lentil soup recipe is so versatile! Here are some ways to customize it:
Lentil Soup Recipe with Chicken: Add 1 lb raw chicken breasts to this soup when it starts to cook, but before serving, remove chicken breasts from the soup, shred on a cutting board, and stir shredded chicken back into the pot.
Lentil Soup Recipe with Sausage: Smoked sausage is a delicious addition to this recipe. We like to brown it in the pan, slice + stir it into the soup while it cooks.
Lentil Soup Recipe with Ham: Add 1 lb chopped cooked ham to this recipe for a delicious protein boost.
Canned Lentils: If you use canned lentils, cut the cook time in half.
Lentils: I have not tried this recipe with anything besides lentils but I think it would also work with split peas! You can also try this Split Pea Soup.
Cheese: I love to add a parmesan cheese rind into soup while it’s cooking. You can also top this lentil soup with freshly grated parmesan cheese. (The soup will no longer be vegan)
Broth: If you like a broth-ier soup, add more liquid (either broth or water). The lentils can also absorb the liquid as they soak. If you are reheating this soup, you may need to add more broth.
Veggies: Feel free to add your preferred veggies to this soup. Mushrooms and zucchini are some of our favorite additions. If you don’t have carrots, celery, or onion (or don’t prefer them) – omit them. You can add 1 teaspoon of onion powder or garlic powder instead!
Dried Herbs: Substitute 2 tablespoons of fresh herbs for every 1 teaspoon of dried herbs.
Salt/Pepper: We use unsalted vegetable broth in this lentil soup recipe and prefer to add salt/pepper to taste. You may need to add more/less to the soup depending on your taste buds.
How To Make
- Sauté onions and garlic in olive oil in a pan for 2 minutes. Add celery and carrots; then sauté for an additional 5 minutes until onions/garlic are translucent.
- Add the soaked and drained lentils, broth, water, tomatoes, and spices.
- Stir and bring to a boil. Once boiling, reduce and simmer for 15-20 minutes until the lentils are tender and carrots are soft.
- Remove the bay leaves and enjoy!
Do I need to soak Lentils?
Soaking the lentils is an important step for this easy lentil soup and if you don’t soak the lentils ahead of time your soup will not cook the same.
This not only affects the cook time but also the flavor and can help to make the lentils easier to digest.
You don’t need to soak lentils, you can cook them in the soup from dry – but it will take longer to cook, can affect the flavor, and you will need to add more broth.
Do you cook lentils before adding to soup?
You shouldn’t cook lentils before adding them to the soup. It’s best to soak dry lentils before cooking them because it helps make them easier to digest, but most lentil soup recipes have the dry lentils cooking right within the broth.

Great recipe so good very easy and healthy. Thank you
I made this in the instant pot and followed the recipe exactly. It was amazing. My roommate, who doesn’t like lentils, loved it too. It was quick, easy and yummy 😋
The most wonderful ,hearty soup!
Suggestions for cooking times in Instant Pot if using canned lentils? Thank you! Looking forward to try! 🙂
Unfortunately I can’t make a suggestion.Raw lentils vs canned cooked lentils are very different so I think these would turn to absolute mush in the instant pot for any amount of time. Sorry!
I made this recipe for my boss when she was recovering from surgery.
A great hearty soup with lots of flavors 💞💞
Hi. I am not all that familiar with dried lentils & there seem to be several types & colors. I have heard that red lentils dont need to be soaked beforehand.Perhaps they are a softer bean? Would you kindly comment on what would happen if I were to use dried red lentils? Thank You!
I’m not sure what would happen with this recipe if you used red lentils – I haven’t tried this recipe with them. I’m sorry I couldn’t be more help!
Its been forever since I had a lentil soup so I was excited to try this and I loved it! I remember growing up on similar recipes and this one for sure one-upped what I remember as a child most likely due to the multiple herbs used. I also really liked the simplicity of the recipe. I am a fan, thank you!
Can you use red or green lentils?
I haven’t tried it with red lentils but I think it would work. These are green lentils.
