Ingredients
Find complete ingredient list, quantities, and substitutions in the recipe box at the bottom of the page.
- Split Red lentils: they cook quickly and give the soup its creamy texture. Green or brown lentils can work, but they’ll need more cooking time and won’t get as silky.
- Olive oil: extra virgin adds richness and a hint of fruitiness. Use avocado oil or light olive oil if that’s what you have.
- Onion: yellow onion gives sweetness and depth. Swap with white onion, shallots, or even leeks for variety.
- Carrots: they balance the earthy lentils with natural sweetness. Sweet potatoes or parsnips work well too.
- Celery: adds a subtle savory base. If you’re out, use fennel for a light anise flavor or skip it altogether.
- Garlic: fresh garlic is best for bold flavor. Garlic powder can be used in a pinch—about ½ teaspoon per clove.
- Ground cumin: warm and earthy. Try smoked paprika, coriander, or dried oregano if you prefer a different spice profile.
- Tomato paste: thickens the broth and adds umami. Substitute with crushed tomatoes, fire-roasted tomatoes, or even a spoonful of harissa for heat.
- Potatoes: give the soup its creamy body once blended. Cauliflower florets or butternut squash are excellent lighter options.
- Vegetable broth: the foundation of this one pot lentil soup. Use chicken broth if not vegetarian, or just water with an extra pinch of salt.
- Lemon wedges: a squeeze brightens the flavors. White wine vinegar or apple cider vinegar can substitute.
- Parsley: fresh herbs finish the soup beautifully. Use cilantro, dill, or chives for a twist.
How to Make Creamy Red Lentil Soup
Step 1 – Sauté the Vegetables and Spices
Pulse onion, carrot, celery, and garlic in a food processor until finely chopped. Heat olive oil in a large pot, add the veggies, and cook 4 minutes. Stir in cumin and tomato paste, and cook 1 more minute until fragrant.
Step 2 – Add Potatoes, Broth, and Lentils
Add the diced potatoes, vegetable broth, and rinsed red lentils. Remember, split red lentils don’t need soaking—just a quick rinse.
Season with salt and black pepper. Simmer gently for 15 to 20 minutes, stirring occasionally, until the lentils are soft and creamy and the potatoes are fork-tender.
Step 3 – Blend Until Creamy
Blend the soup with an immersion blender until smooth, or cool slightly and blend in batches in a standing blender.
Step 4 – Taste and Serve
Adjust seasoning, thin with extra broth if needed, and serve hot with a squeeze of lemon juice, a sprinkle of parsley, and optional chili oil for a perfect, cozy, Mediterranean lentil soup.
Tips
- Rinse the lentils well: A quick rinse removes dust and helps the soup cook into a smooth, creamy base.
- Cut the potatoes small: Smaller pieces cook faster and blend more easily into the soup’s silky texture.
- Don’t skip the tomato paste: It adds depth and richness, turning this into an easy lentil soup recipe you’ll make on repeat.
- Stir while simmering: Lentils can settle at the bottom, so give the pot a stir every few minutes.
- Adjust the thickness: Add more broth if you prefer a lighter soup, or let it cook down for a heartier version.
- Brighten with lemon: A squeeze at the end balances the earthy flavors and keeps it fresh.
- Blend carefully: For a rustic feel, only blend half the soup, leaving some chunks for texture.
- Use fresh herbs: Parsley adds freshness, but mint or dill can also lift this healthy vegetarian soup.
- Serve with bread: A slice of crusty bread makes it a filling, balanced meal and turns it into a true vegetarian dinner idea.

5 STARS
Just prepared this soup! I used 1/2 of a cauliflower instead of potatoes and it’s WONDERFUL! I am salt free so the addition of lemon and chopped parsley garnish made the soup so good. Will make the vegan carrot cake later today. It’s also a fantastic recipe!
Can this be made without a blender? Air B&B doesn’t provide one
Hi Diane, Yes you can – but the texture is gonna be more like a lentil dal, more rustic but DELICIOUS!!
So, simmer for 20-25 mins until the red lentils collapse. Then mash in the pot with a potato masher/whisk (or the back of a spoon) to your preferred creaminess.
I hope this helps, enjoy your AirBnB cook-up 😉
I love the recipe and I have made a few of your dishes for my family ❤️
Fantastic, Sandra – I am so very happy to hear that (and so is Nico, as I read him your message, he smiled).
Thanks for being here. Kindest,
Louise
