A golden, aromatic broth filled with tender lentils and carrots, finished with a swirl of citrusy herb oil and a dollop of tangy lemon yogurt for a perfect balance of warmth and brightness.
Recipe Details

- Total Time: Approximately 45 to 50 minutes.
- Difficulty: Easy. This recipe focuses on simple vegetable prep and a gentle simmer.
What You’ll Need
This soup relies on high-quality aromatics and a few secret ingredients to stand out. You will need green or brown lentils, fresh carrots, and a large yellow onion. The complex flavor comes from preserved lemon peel, Aleppo pepper, and a “Bouquet Garni” of fresh thyme and bay leaves. Nutritional yeast is used at the end to provide a rich, savory umami finish.
Ingredient Notes
- Preserved Lemon Peel – This is the star of the show. It provides a salty, fermented citrus flavor that is much deeper than fresh lemon zest.
- Aleppo Pepper – A Mediterranean chili flake that has a mild, fruity heat and a hint of saltiness.
- Green or Brown Lentils – These varieties hold their shape well during simmering, providing a nice texture compared to red lentils which tend to break down.
- Nutritional Yeast – This provides a savory, almost cheesy depth without the need for dairy, making the soup base rich and satisfying.
- Herb Oil – A fresh finishing oil that prevents the earthy lentils from feeling heavy.
How to Make Mediterranean Lentil Soup
1. Sauté the Aromatics
Heat 2 tablespoons of olive oil in a Dutch oven or large soup pot over medium-high heat. Once shimmering, add the diced onion and 1/2 teaspoon of kosher salt. Cook until the onion has softened and turned a beautiful golden brown, stirring occasionally for 10 to 15 minutes. If the onions begin to brown too quickly, add a small splash of water to scrape up the browned bits.
2. Build the Flavor Base
Add the diced carrots, garlic, and finely chopped preserved lemon peel to the pot. Stir frequently for about 5 minutes until the carrots just start to soften. Add the Aleppo pepper and ground coriander, stirring constantly for 30 seconds to “toast” the spices. If the pot seems too dry or the spices look like they are scorching, deglaze with a splash of water and lower the heat slightly.
3. Simmer the Soup
Pour in a splash of broth and scrape up any browned bits from the bottom of the pot. Add the remaining broth, 1 cup of water, the lentils, the tied herb bundle (Bouquet Garni), and about 10 twists of black pepper. Stir well, cover, and bring to a boil. Once boiling, reduce the heat to a low simmer. Keep it covered and simmer for 20 minutes or until the lentils are tender. Occasionally check to ensure the soup isn’t bubbling too rapidly.
4. Prepare the Finishing Touches
While the soup simmers, prepare your toppings:
- Herb Oil: Zest the lemon. Finely chop the fresh herbs (basil, dill, and/or parsley). Mix the herbs and lemon zest together in a small bowl. Stir in the remaining 2 tablespoons of good-quality olive oil and two pinches of flaky sea salt.
- Yogurt Sauce (Optional): In a small bowl, mix the 1/2 cup of yogurt with 1 tablespoon of fresh lemon juice, and season with salt and pepper to taste.
5. Final Seasoning and Assembly
When the lentils are tender, remove the bay leaves and thyme sprigs. Stir in the nutritional yeast and gently cook, uncovered, for 1 to 2 minutes. Remove the pot from the heat and stir in 1 tablespoon of fresh lemon juice. Taste and adjust with more salt or lemon juice as desired. Serve the soup in warm bowls, spooning a generous amount of Herb Oil and a dollop of yogurt sauce over each. Serve immediately with crusty bread.
Pro Tip: If you prefer a richer, more savory flavor, don’t be afraid to add the full 3 tablespoons of nutritional yeast. It adds a wonderful thickness and “umami” that makes the vegetable broth taste like it has been simmering for hours.
Recipe Tips
- Rinse the Lentils: Always rinse your dry lentils in a fine-mesh sieve and pick through them to remove any small stones or debris before adding them to the pot.
- Don’t Overcook: Check the lentils at the 18-minute mark. You want them to be tender but still hold their shape; if they cook too long, the soup can become mushy.
- Preserved Lemon Prep: Only use the peel of the preserved lemon. Discard the pulp and rinse the peel if you find it too salty before chopping.
- Deglazing: Using water to deglaze during the onion and spice phases is the secret to getting all that “fond” (browned bits) into the soup for maximum flavor.
FAQs
Can I use red lentils? Red lentils will cook much faster (usually 10-12 minutes) and will break down into a thick puree. If you use them, the texture will be a thick porridge rather than a clear soup with distinct lentils.
How do I store leftovers? This soup is even better the next day! Store it in an airtight container in the fridge for up to 4 days. You may need to add a splash of broth when reheating as the lentils will continue to absorb liquid.
What if I don’t have preserved lemons? While preserved lemons have a unique flavor, you can substitute with the zest of one large fresh lemon plus an extra pinch of salt, though the flavor profile will be less complex.
Serving Suggestions
- Bread: A thick slice of sourdough or a warm baguette is essential for dipping.
- Extra Greens: Serve with a side of sautéed kale or a simple arugula salad for extra freshness.
- Toppings: Toasted pumpkin seeds (pepitas) can add a nice crunch along with the herb oil.
Make This Recipe in Advance
The soup itself can be made up to 2 days in advance just wait to add the final tablespoon of lemon juice until you are reheating it to keep the flavor bright. The yogurt sauce can also be made a day ahead. However, the Herb Oil is best made fresh just before serving so the herbs remain vibrant and green.
