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.

Hi! We are Nico & Louise
We’re here to share delicious, easy, and healthy plant-based recipes (vegetarian & vegan) 🌿✨.
Welcome to our blog, we are glad you are here.
Followed the recipe sans subbing 2 cups of chicken broth and using brown lentils. Easily the best lentils soup I’ve made!
Fantastic, Rachel!! I’m so happy that you made the soup yours. Thanks for sharing your feedback here. Kindest,
Louise
Will using frozen cauliflower florets or white beans instead of potatoes make it be creamy?
Hi Sofia! We haven’t tested those swaps, but in theory they can work. Here is what Nico and I discussed:
– Frozen cauliflower: try 3–4 cups (300–400 g), simmer until very soft, then blend. Start with less broth and add as needed.
– White beans: try 1 can (15 oz / 400 g) drained, simmer 10 min, then blend… You may need to thin with broth 🙂
Texture may be a bit different from potato. If you try it, we’d love to hear how it goes. Cheers,
Louise
Great recipe. Looking forward to receiving seafood soup recipes.
