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.

This recipe is always the first choice for cool fall and winter lunches. We make a huge pot then freeze in smaller batches, for quick dinners or lunches. It freezes well even with the kale. Each time we take a batch out, we add our leftover veggies ( roasted sweet potatoes, or broccoli etc. from the day before ), so that each batch is packed with extra veggies and has its own unique taste. Great recipe! Have sent it to so many family and friends! Yummy!!!!
Wow, I love that!! Adding leftover roasted veggies to batch-made soup from the freezer is such an amazing idea!! Thank you for the inspiration, I will have to try it myself! So happy you love the recipe. Thank you for sharing with your loved ones!
I loved this!! I added about 2 tbsp of chipotles in adobo and 1tbsp of tomato chicken bouillon to make the flavor similar to a mexican lentil soup. I loved it! So concentrated and perfect for fall weather.
Thank you!! So happy you liked it. Love your added ingredients, they sound so good!
Really tasty – added some crispy bacon and Parmesan on top ( not veggie), but even without it would still be lush!
Thanks, Lynda! So glad you liked it!!
I’m confused when it says ‘dried’ lentils? Since they have to be rinsed and the recipe says to toast them….It’s ok to toast them after you soak them?
Hi Tina, lentils sometimes come in a can but you’ll need a bag of dried lentils for this recipe. They will toast fine after being rinsed!
So good! Used stock I made from leek tops. Added fresh jalapeño pepper and some Yukon taters. Squeezed lemon juice in before serving. Sprinkled nooch atop. Yum.
Your tweaks sound amazing!! Especially homemade leek stock, yum!
I think this recipe might be missing a critical piece of info, which is that the pot should be covered for the 30 minutes that the lentils are cooking. I left it uncovered (per the recipe) and they were almost raw after 30 minutes.
Hmm, that’s odd. What kind of lentils did you use? As I mention in the recipe, different types on lentils can take longer to cook. I use whole green lentils and they are tender after simmering for 30 minutes uncovered.
This is a great lentil soup! I ended up doubling everything to have leftovers for us during the week, and the leftovers are almost better than the day of. I added in more chili flakes because I like it spicy, and then I topped it off with parmesan cheese and it’s soo good! This will definitely become a staple in our kitchen!
Yay, thanks so much!
