Lentil Kale Soup is a hearty vegan recipe that is easy to throw together with green lentils, onions, celery, carrots and kale - 13 grams of protein/serving!
For a wholesome, vegan and protein-packed soup recipe, try this Lentil Kale Soup. It’s made with simple vegetables like onions, celery and carrots, loaded with plant-protein rich lentils and then finished off with some kale. What I love about the lentil soup is that it’s nutritious, delicious and will leave you feeling so full and satisfied.
Lentils are made up of over 25% protein, which is an excellent source of protein if you are trying to avoid meat. They are also rich in fiber and a great source of iron, which can sometimes be lacking in vegan diets. They are so often overlooked, but it’s definitely a Mediterranean staple that I always have in my pantry to make dishes like Mujadara and this kale lentil soup.
How to make the lentil soup recipe
- Start by heating a deep pot with olive oil and adding the mirepoix – onions, celery and carrots.
- Cook those vegetables together until they become soft and aromatic. You can add the garlic in the final minute of cooking so that it softens but doesn’t brown.
- Next, add the dried green lentils and the seasoning. I’m using cumin, coriander, salt and pepper. Give all that a good toss to combine and lightly toast the lentils.
- Add the vegetable broth or water and cook on low for 30 minutes. You want the lentils to become tender and the vegetable broth to thicken. This time may longer for different lentils.
- And that’s your cue to add in the kale or other leafy greens you might be using.
- When you notice the kale has wilted, it’s time to serve the lentil kale soup!
The result is a hearty lentil vegetable soup that you can enjoy as a starter or as a full meal. The spices give it a warm earthy flavor and the vegetables add great texture to the tender lentils.
Tips for making lentil kale soup
- Sift through the lentils and rinse them in a colander to remove any debris. It’s not always likely, but sometimes there are some tiny stones hidden between the lentils; and this tip limits any surprise bites 😉
- Read the package directions for the exact cooking time for the lentils you use. There are a variety of lentil types and brands, so just like cooking pasta, the cooking time may vary. 30 minutes of simmer should cover all types, but double check to be on the safe side. You can always test one by mashing with a fork.
- Chop the kale finely before adding to the soup. Even though kale wilts down when added to the hot broth, it doesn’t wilt as much as spinach. To make it easier to fit all the ingredients into a bite size, it’s best to chop it small.
- For a thicker base, use an immersion blender and lightly blend. I like seeing the vegetable chunks and whole lentils in this kale lentil soup. But if you wanted a thicker base, you can lightly blend the soup before adding the kale.
Frequently Asked Questions
Can you make this soup ahead of time?
Soup is such a great make ahead and freezer meal. I often make a big batch and freeze half. Let the soup cool to room temperature before transferring it to an airtight container. It will keep to four or 5 days in the fridge an up to 3 months in the freezer. Reheat the soup on the stovetop or in the microwave from frozen or chilled.
What are the best lentils to use?
I like to use green lentils in this soup as they hold their shape really well when cooked, unlike red lentils which can get mushy. You can add the dried green lentils straight into he soup, no need to pre-cook them. If you only have red lentils, you can use these, but you will need to reduce the cooking time.
