    Mediterranean Red Lentil Soup

    Super easy, healthy, and incredibly delicious, this cozy red lentil soup is seasoned with Mediterranean spices and a touch of harissa for some kick! This naturally vegan and gluten-free soup is perfect for chilly evenings.

    This soup was one of my favorite things to cook when I was in law school. It's go so much going for it! For one thing, it's a pretty cheap meal (and funds were low back then). For another, the quick throw-stuff-in-a-pot-and-let-it-simmer approach to cooking was perfect during exams time.

    I wasn't the only one that was a big fan of this soup back then. At some point a mouse moved into the kitchen of the house I was renting, residing somewhere beneath my oven. Whenever this soup was cooking, he'd pop his little head out of one of the burners that weren't then being used and turn his nose up in the air, sniffing away.

    I didn't really mind. It was cute and I took it as a compliment. I did get a little nervous at times that I'd light a burner without realizing he was approaching, so I got in the habit of banging on the stove top to scare him away before lighting up, just in case.

    We eventually did have to relocate the mouse and his family. I just wasn't comfortable with the thought of them scampering all over my dishes and utensils while I wasn't looking. I'm happy to say that we caught them all with humane traps and relocated them to Philadelphia's Fairmount Park, where they (as far as I'm concerned) lived out the rest of their little mouse lives happily.

    Why Red Lentils?

    I love the flavor and texture of split red lentils, but they've also got the advantage of quicker cooking time compared to other types of lentils. About 20 minutes of simmer time is all it takes for these lentils to completely soften up and fall apart.

    Make sure your red lentils are split. Usually the ones available at supermarkets are, but occasionally I come across some that aren't. If your lentils aren't split, they'll take much longer to cook, and your soup will have a completely different consistency.

    What You'll Need

    • Olive oil. Any high heat oil will technically work, but olive will give your soup the best flavor.
    • Onion.
    • Garlic.
    • Spices. We're using ground cumin and coriander.
    • Red lentils. Make sure to use split lentils — not whole ones.
    • Vegetable broth. I like Better Than Bouillon in seasoned vegetable flavor.
    • Diced tomatoes. Use canned diced tomatoes that are packed in juice or sauce.
    • Lemon juice. Use freshly squeezed juice for the best flavor.
    • Harissa paste. This is a spicy north African chili paste. Many supermarkets carry it in the international foods section (Trader Joe's has it!). You can substitute another hot sauce or just leave it out for a milder soup.
    • Herbs. Top your soup with some fresh parsley or cilantro.

    How to Make Red Lentil Soup

    Follow along with the photos below if you need some guidance on how to make this dish, or scroll all the way to the bottom of the post if you just want the recipe!

    • Heat up some olive oil in a large pot, then add diced onion. Sweat the onion for a few minutes, until it begins to soften up.
    • Add minced garlic and your spices and sauté them very briefly with the onion. Sautéing the spices for a minute (but no longer!) brings out their flavors.
    • Add broth, tomatoes and your red lentils. Raise the heat and bring the liquid to a simmer.
    • Let everything simmer for a bit, until the lentils are soft. Add a squeeze of lemon juice. If you like your soup on the spicy side, stir in some harissa paste at the end.

    Leftovers & Storage

    Leftovers of this soup keep very well for about 3 days in the fridge. The soup may thicken up a bit over time, but I personally like that! If you don't, just thin it with a bit of broth or water.

    Frequently Asked Questions

    Is this soup gluten-free?

    It sure is!

    Can I substitute another variety of lentil?

    Perhaps, as long as the lentils you use are split. If they're not split, the tomatoes could prevent them from cooking fully.

    Is this red lentil soup spicy?

    The harissa gives it a little kick. Use extra if you'd like your soup to be extra spicy, or leave it out for a heat-free version.

    Ingredients

    • 1 tablespoon olive oil
    • 1 medium onion, diced
    • 4 garlic cloves, minced
    • 1 tablespoon ground cumin
    • 1 teaspoon ground coriander
    • 1 ½ cups dried red lentils
    • 5 cups vegetable broth (4 cups if using the Instant Pot method)
    • 1 (14 ounce or 400 gram) can diced tomatoes

    • Fresh chopped cilantro or parsley, for serving
    US Customary - Metric

    Instructions

    Stovetop Method

    1. Heat the olive oil in a large saucepan over medium heat. Add the onion and cook, stirring occasionally, until soft and translucent, about 5 minutes.

    2. Add the garlic, cumin and coriander, and sauté for another minute, until the garlic becomes very fragrant.

    3. Stir in the lentils, broth and tomatoes. 

    4. Bring the liquid to a boil, lower the heat to a simmer, and allow to continue simmering, uncovered, until lentils are soft, about 20 minutes. Thin the soup with some water if it becomes too thick while simmering.

    5. Stir in the lemon juice and harissa (if using). Season the soup with salt and pepper to taste.

    6. Ladle into bowls and top with parsley and/or cilantro.

    Instant Pot Method

    1. Press the "sauté" button on your Instant Pot and add the oil.

    2. Give the oil a minute to heat up, then add the onion. Cook the onion for about 3 minutes, stirring occasionally, until soft and translucent.

    3. Add the garlic, cumin and coriander, and sauté for another minute, until the garlic becomes very fragrant. Press the "cancel" button.

    4. Stir in the lentils, 4 cups of broth, and tomatoes.

    5. Place the lid on your Instant Pot and set the valve to the "sealing" position. Press the "pressure cook" or "manual" button and set the pressure to high. Set the soup to cook for 10 minutes.

    6. When the soup has finished cooking, carefully move the valve to the "venting" position. Let the pressure release completely.

    7. Remove the lid from the Instant Pot. Stir in the lemon juice and harissa (if using). Season the soup with salt and pepper to taste.

    8. Ladle into bowls and top with parsley and/or cilantro.

        Thank you! This is fantastic with harissa, but if you have a hard time finding it you could sub your favorite hot sauce. I've also seen a few recipes online for DIY harissa, but haven't tried myself yet so I can't say if they're any good. Enjoy!!

          Harissa is not all that difficult to make your own. Harissa is comprised of dried red chilies, garlic, oil, an acid (I use either Balsamic or Apple Cider vinegar & lemon juice), and your preferred spices "constructed" to your own taste preference. .Pretty much easy peasy.

        Instead of harissa consider sauteing a seeded / chopped serrano pepper along with the onion. Serranos are a bit hotter than Jalapenos, but their heat is an 'up front' heat in the mouth. Some eat them raw. I am not one of those folks. Also, I cook up some hull-less barley and add it to the soup when i reheat a portion. Basmati Rice is the more typical add-on product. Either is complimentary to the incomplete protein in the bean, so that you have a whole protein. Filling, lasting and complete.

      I absolutely love the mouse story. We are the same in our house. We have cats who catch the mice, bring them to us and we then take them out to our shed and release them. A few days/weeks later the story repeats. Our son has suggested marking these little guys so we can tell if they are repeats or just new kids on the block looking for a warm,dry home. I have long been a fan of your recipes and life values. Thanks for all the delicious recipes and heart warming life style.

        Oh wow, that's great that they're okay and you're still able to release them! I have cats too, and I was always so nervous that they'd catch the mice. They only ever got one though - it was a baby and I found them staring it down in the dining room, I think to scared to move. He was totally fine, and I took him to the park just like the others. :)

      I loved your little mouse story - once I had a mother possum with two babies on her back living underneath my stove. I tried every means of catching them to reloicate - I was living next vto a river - no luck. Then my dad said "do you really think she WANTS to live under your stove?? (well yes in some ways because she used to eat all my sweet potatoes and apples !!) - he told me to open the doors & leave for a while - sure enough she left and moved into a tree near the river. Also thankyou so much for your fabulous recipes - I love them xx :-)

      This is absolutely amazing! I am just trying our weight watchers also and love lentils and was looking for something last minute I had ingredients for. One of the best first pass recipes I’ve ever tried. I used sriracha instead of harissa and messed up and put a full tablespoon of coriander. The result was a very rich and nicely spiced delight.. a lot like eithiopian lentil dishes I absolutely love. This one is a big winner for a rich and savory (not to mention easy) guiltless dish. Thank you!!!

      I just made this for lunch as I had red lentils and not much else around the house to eat. It was awesome. I only had 4 cups of vegetable broth so I added water to make up the difference. I sauteed the vegetables in some broth instead of oil. I used 1 tsp salt and 10 grinds of pepper. Instead of Harissa paste I used 1 tsp of Sriracha sauce. It is a 10 star for me. So yummy! Thanks for sharing.

      Neither Whole Foods nor Safeway have split red lentils. The lentils they sell are so small I wonder how they could be split and why it would make such a big difference in the recipe. Further, I was unable to find harissa paste. I live in a large metropolitan area. Please help me find these ingredients.

        Whole lentils will probably work, but the soup will have a different consistency and take longer to cook. Do you have a Trader Joe's nearby? They carry both ingredients. If you can't find the ingredients in stores I think online would be your best bet would be online - Amazon has them.

      I LOVE this recipe Alissa. Thanks SO MUCH for creating and posting. Tonight is my 2nd time making it abd it'll definitely be in my meal prep line up. I personally only use one carton of low sodium veggie broth equivalent to four cups and used the hot fire roasted diced tomatoes qith cayenne pepper, no coriander(I don't have any lol) and no lemon juice or fresh garnish. AMAZING!!!! HAPPY THANKSGIVING if you celebrate, enjoy time with loved ones.

        Could you have burned your onions or garlic and spices? That will usually do it.

      My husband is not a fan of soups, but he really likes this one. The Harissa paste is a unique flavor for us, and we love it. And so easy! It was the first recipe I made of yours. The recipe is a keeper as is your wonderful site.

      Easy and delicious! We followed this as written, but puréed it for a picky eater.
      Great with a side of toasted naan or pita.
