If you ever thought lentils were bland or boring, the flavors in this easy lentil soup recipe will surprise you in a big way! This spicy lentil soup is loaded with aromatics and bold Mediterranean spices and amped up with spinach for a nutritious and satisfying vegan dinner.
It is no secret that I am a huge fan of lentils (yes, I’m obsessed)! Dried lentils are a year-round ingredient in my Mediterranean pantry, I really try not to run out of them. Unlike other dry legumes, lentils are easy to work with, requiring no fuss or overnight soaking. And they are an easy way to add heft and nutrition to your diet, especially since they pack lots of protein and fiber!
I’m a fan of using lentils in stews, salad, or even in a sauce for a vegetarian moussaka! And today, we’re going for one of my favorite lentil recipes perfect for cooler weather—spicy lentil soup!
Lentil soup with a Mediterranean kick!
With green lentils, a bag of frozen spinach, and a few spices, you can make this wholesome one-pot meal in 30 minutes or less!
If you’ve tried plain steamed lentils, you’ve probably noticed their neutral taste with a subtle sweetness. That’s why lentils take so well to different flavors.
In this lentil recipe, I start with onions and garlic cooked in good extra virgin olive oil, adding in Mediterranean spices like cumin, coriander, and sumac. The spicy kick comes from a dash of crushed red pepper flakes, which you can adjust to your taste if you don’t want the soup to be too spice. A splash of lime juice is the bright pick-me-up finish, I highly recommend you don’t skip it!
I prefer to keep it vegan, but this green lentil soup pairs well with a quick side of your favorite chicken sausage (you may get something similar to my earlier Italian sausage and lentils).
Best lentils to use for lentil soup
For this lentil spinach soup, I recommend using green lentils, black lentils, or small brown lentils. Like my Italian lentil soup with green lentils, texture is a big part of this dish. I like that these varieties of lentils will cook to tender perfection while holding their shape.
Red lentils and yellow lentils cook faster than other lentil varieties, and they do tend to lose their shape becoming more on the mushy side. This makes red lentils perfect for thick and creamy soups like my Greek red lentil soup, where a silky consistency is the goal.
Ingredients: What you need for this lentil soup recipe
- Quality extra virgin olive oil – I like our Hojiblanca Spanish EVOO in this recipe. It is a moderately intense olive oil, with a finish that is both fruity and slightly bitter.
- Yellow onion – Use one large finely chopped onion
- Garlic – One to two large cloves, minced
- Spices – Ground coriander provides warm earthiness, ground cumin has a slight bitterness that goes well with sweet lentils, sumac is astringent with a bit of puckery sourness, and crushed red peppers add a hint of a kick. Any mild to spicy red pepper will work, like Aleppo-style pepper.
- Herbs – Dried mint flakes add a cooling, woody quality to the spicy lentil soup, while fresh flat leaf parsley added at the very end brings bright, peppery flavor.
- Pinch of sugar (optional) – This helps play up the natural sweetness of the lentils, but you can eliminate the sugar if you need to
- Pinch of flour – Use any flour of your choice. This is to give the soup a bit of thickness and body.
- Vegetable broth – Preferably low-sodium broth.
- Frozen cut leaf spinach – A one-pound bag of frozen spinach, no need to thaw: It goes into the pot straight out of the freezer!
- Lentils – Green, black, or small brown lentils. Rinse the lentils well and drain them before using in this recipe
- Fresh lime juice – Juice of 1 lime to finish the soup. The citrus will elevate the flavor and bring some brightness to this warm and comforting soup.
How to make lentil soup from scratch
Here’s how to make this spicy lentil soup (printer-friendly recipe below):
- Sauté the onions, herbs, and spices. Grab a large ceramic or cast-iron pot and heat 2 tablespoons of extra virgin olive oil over medium heat. Add a chopped yellow onion and sauté until golden. Add a clove of chopped garlic, 1 ½ teaspoon ground coriander, 1 ½ teaspoons cumin, 1 ½ teaspoons sumac, 1 ½ teaspoons crushed red pepper, 2 teaspoons dried mint flakes, a pinch of sugar, and 1 tablespoon of flour. Cook for 2 minutes, and stir regularly.
- Add broth and the lentils and cook the soup. Add 6 cups of low-sodium vegetable broth and 3 cups of water to the pot. Turn up the heat to high and bring to a rolling boil. Add 1 ½ cups green lentils or small brown lentils that have been rinsed, along with 12 oz of frozen cut leaf spinach (straight out of the bag; no need to thaw). Keep the heat on high and cook for 5 minutes. Reduce the heat to medium-low, cover, and cook for 20 minutes, or until the lentils are fully cooked. (Depending on the age of your lentils, this can sometimes take up to 45 minutes.) Keep an eye on the liquid levels. Lentils absorb a lot of liquid, so you may need to add hot water if the soup starts looking dry.
- Finish with lime juice and fresh parsley. Stir in the juice of one lime and 2 cups chopped flat leaf (Italian) parsley. Cover and remove from the heat. Allow the soup to rest for 5 minutes. Serve hot by itself, or with pita or your favorite crusty bread.
How long to cook lentils?
Green, black, or brown lentils, as recommended for this recipe, can take a while to cook. It depends on the lentil, but they can take anywhere from 20 to 45 minutes to become tender. Older lentils tend to have a longer cooking time, so if your lentils have been sitting in the pantry for a long time, they may take longer than expected. Red lentils only take about 15 minutes to cook.
Make-ahead for even better flavor!
If you are able to, make this lentil soup recipe the day before you want to serve it. This will give the flavors a chance to meld better and will thicken up the soup as well, making it even more comforting.
Serve it with
Because this Mediterranean lentil soup is so hearty and filling on its own, you don’t need to add much aside from your favorite pita or freshly baked rustic Italian bread to sop up all the soup. But I do like to start with a big salad for more plant-based goodness.

Leftovers and storage
Once it reaches room temperature, transfer the lentil soup to an airtight container and refrigerate. It will keep for up to 5 days. Reheat the soup in a saucepan over medium heat. You might need to add some water if the soup has become too thick.

Started my family on the Mediterranean Diet recently and found your blog in my recipe search. Made this soup 2 days ago and still eating it! As many have said it is even better the next day(s). Spent 5 weeks traveling thru Greece, staying with friends/family of a childhood friend and miss the flavors of all those home cooked meals. Looking forward to trying more recipes! Oh…and also, couldn’t find Sumac and used lemon zest 🙂
Stacy, so great to hear from you! Thank you for taking the time to share. And I’m glad you enjoyed this recipe. Happy cookin!
Hi! I really like lentil soup but now that I have serious gut issues, I can no longer eat many foods; unfortunately, garlic, onions and lentils are among those. However, I am willing to make your delicious looking recipe without the garlic, and I will use the green parts of green onions, which I am allowed to do. Supposedly canned and rinsed lentils are easier to digest so I will use those. All that to say…or ask, should I omit the water entirely? And, I guess I should double the lentils right away, since they won’t double in size, in this case. Thanks so much for your reply and of course, for sharing your recipe.
Hi Sharleen,
Sorry to hear of the stomach issues; certainly sounds challenging. Canned lentils are already cooked, so you’re right, you won’t need water to cook them. With all the alterations you have to make, and with the fact that you don’t need water, it’s probably going to be quite a different recipe. But worth a try! I have two lentil salad recipes that may be easier to change. Here are the links: https://www.themediterraneandish.com/brown-lentil-salad-recipe-pomegranate-swiss-chard/ And https://www.themediterraneandish.com/lentil-salad-recipe/ Still, you have to adjust the spices, but you could easily use canned lentils in either of these. Hope this helps a little.
Looks great… Will be making this. The pics seem to show way more Lentils than the 1 & 1/2 cups on the ingredient list. Am I wrong??? Thanks, Slu
Hi Stephen! So, when you start with 1 1/2 cup of dried brown lentils, you pretty much end up with something like 3 cups of cooked lentils. But what is in the photos is exactly what is listed in the ingredients; I promise 🙂 Hope you enjoy it!
Wonderful soup! I omitted the sugar, and used a smaller amount of fresh spinach from the garden. My husband loved it, and so did I.
Great to hear, Nikki! Thank you for sharing!
Amazing soup Suzy!! Will be making it again soon!
Thank you, Cindy! I am so glad you enjoyed it!!! This one is even better the next day when all the flavors have settled. XO
Hi Suzy,
Made the lentil soup Saturday I loved it, made this just for me and made jerk chicken wings for my wife so she couldn’t complain?. I loved it and will be eating and enjoying all day today, the only thing is! I used canned lentils, I realized I had to much fluid for this I guess that’s why you said to use dry lentils lol. Still was very good, can green lentils or red lentils be used in place of brown lentils? Oh today I am cooking your braised salmon for my wife, I will continue to enjoy the soup,
wish me luck with the salmon for my wife lol?
WOW, you,re not kidding it’s better the next day, it’s like lentil soup on steroids or the 3.0 version over 1.0 I’m really enjoying this. Had to add this to my original post.
I too made this soup yesterday and it was very good. I didn’t have the sumac spice so I substituted with some fresh lemon juice. I will most definitely try more of your recipes.
Yay! Glad you liked it, Pamla! Thank you for sharing
Really want to try this soup but do not have sumac. Is there a sub I can use? Also have fresh spinach. How much would I use?
Hi Melody, I often buy sumac online, here is a link that might be helpful: http://amzn.to/1Sqg8IA. In this recipe, sumac provides a bit of a tangy taste that’s exaggerated by the use of lime juice at the end. So you can omit sumac; adjust the remaining spices and lime juice to your liking. Fresh spinach will work just as well, you can probably even add it a little later in the cooking process. I would say a good 8-oz bay of fresh baby spinach would work here. Feel free to experiment though to make this soup your own. Enjoy!
Have made this soup twice already. It’s the best! I substituted zest of one lemon for sumac and it tasted great.
Glad to hear it Caroline!!! Thank you for taking the time to share.
Melody,
