Red Lentil Soup
This vegan red lentil soup is a creamy, Lebanese-style bowl that comes together in about 30 minutes with one pot and a blender. Red lentils, garlic, onion, carrots and celery root simmer until soft, then blend smooth with olive oil, a little sweet paprika and a squeeze of lemon. It is naturally plant-based, light yet satisfying, and the kind of soup you can eat warm in winter or cooler in summer.
Red lentil soup holds a special place in my heart, offering a creamy texture and refreshing taste that I simply adore. It is so irresistible that I often find myself going for double or even triple servings every time I prepare it!
The ingredients that make it creamy
The base is simple, and every ingredient pulls its weight. Red lentils are what make this soup creamy without any dairy. As they cook they break down and thicken the broth on their own, which is why a quick blend turns everything into a velvety puree. Let me remind you that red lentils do not require a pre-soaking process, so just place them in a large enough pan with water or the broth of your choice.
Celery root and carrots add natural sweetness and body, while onion and a generous five cloves of garlic build the savory backbone. A little sweet paprika brings warmth and color, olive oil rounds everything out, and the peeled half lemon, added at the end, lifts the whole bowl with a bright, fresh finish. Salt to taste is the last thing you adjust, once the soup is blended and you can taste it properly.
How to get it smooth and balanced
Add only enough water to just cover the lentils and vegetables. It is much easier to thin a thick soup at the end than to rescue one that turned out watery, so start conservative and blend in more water if you want a looser texture. Bring it to a boil over medium heat and let it simmer until the lentils and vegetables are fully tender, around 15 minutes. The lentils should mash easily against the side of the pot when they are ready.
Take the pot off the heat before you add the olive oil, lemon, paprika and salt, then blend. A vertical (immersion) blender right in the pot is the easiest way to get that smooth, creamy consistency with no extra dishes. Add the lemon a little at a time and taste as you go: it should brighten the soup without overpowering the earthy lentils.
Why this method works
Red lentils are split and have no seed coat, so they cook fast and collapse into a puree as their starches release. That is what gives the soup its thick, creamy body without cream or flour. Adding the olive oil and lemon off the heat protects their fresh flavor: olive oil keeps its character when it is not boiled hard, and the lemon stays bright instead of turning flat. Blending while everything is hot pulls the oil into the soup so it tastes rich and rounded rather than oily.
What to serve with red lentil soup
This soup is light enough to start a meal and hearty enough to be lunch on its own with good bread. If you want to build it into a fuller spread, pair it with other plant-based favorites like my dal kofta lentil balls in curry sauce or some spicy vegan lentil cakes for a lentil-forward menu. For a bigger soup-and-something spread, it also goes nicely alongside a fresh vegan Olivier salad.
Storing and making it ahead
This is a great soup to make ahead. Keep it in an airtight container in the fridge for up to 4 to 5 days; the flavor actually deepens overnight. It thickens as it sits, so just stir in a splash of water when you reheat it to bring back the consistency you like. It also freezes well for a couple of months, so I often make a double batch and tuck half away for a busy day. If you love having soups on hand, you might also like my cream of mushroom soup with thyme and this comforting cream of potato and carrot soup, both of which keep just as well.

Frequently Asked Questions
Yes, this red lentil soup is completely vegan. It is made entirely from plant-based ingredients: red lentils, garlic, onion, carrots, celery root, lemon, olive oil, sweet paprika and salt. There is no dairy, cream or any animal product, and the creamy texture comes from the lentils themselves.
No, red lentils do not require any pre-soaking. They are split lentils with no seed coat, so they cook quickly and break down on their own. Just rinse them and add them straight to the pot with enough water to cover.
The creaminess comes naturally from the lentils. As red lentils cook, they release their starches and collapse into a thick puree, so a quick blend with an immersion blender turns the whole pot smooth and velvety. No cream, milk or flour is needed.
About 30 minutes from start to finish. The lentils and vegetables simmer until tender in roughly 15 minutes, then you add the remaining ingredients and blend everything smooth, which takes only a couple of minutes more.
Stored in an airtight container in the fridge, it keeps for about 4 to 5 days and the flavor deepens overnight. It also freezes well for a couple of months. Because it thickens as it sits, stir in a splash of water when reheating to loosen it back up.
Both work well. This soup is versatile enough to enjoy warm in colder months or cooler in summer. Either way, taste and adjust the lemon and salt just before serving, since chilled soups often need a little extra seasoning.

Hey Ruxandra, imi plac mult retele tale, in mod special pt ca sunt simple si in acelasi timp gustoase. Multe dintre retete au la baza principii similare cu retetele ayurvedice, in caz ca iti place mancarea indiana poti sa gasesti multa inspiratie si de acolo. Multa bafta in continuare.
Buna Irina! Multumesc mult! 🙂 Chiar am inceput sa gatesc si mancare indiana. Am facut eggplant dhal si o sa postez reteta in curand.
Haven’t eaten anything this delicious in a long, long time! I didn’t even have the patience to blend it, I ate it like that, chunky and delicious.. and I wasn’t even hungry! :)) THANK YOU so much for this recipe, I am in love with this dish!
