Easy Lebanese Lentil Soup with Cumin and Fresh Lemon

Easy Lebanese lentil soup, often called shorbet adas, is a comforting soup of red lentils, rice, warm spices, and lemon, served hot with herbs or bread. Lebanese home-style versions vary, but this straightforward one-pot method makes a thick, gently creamy soup without needing cream or a blender.

Ingredients

1½ cups (285 g) dried red lentils, picked over and rinsed
⅓ cup (65 g) long-grain white rice, rinsed until the water runs mostly clear
1 large yellow onion (about 200 g), finely diced
1 medium carrot (about 100 g), peeled and finely diced; optional, for a little sweetness
2 tablespoons (30 ml) olive oil
3 garlic cloves (about 9 g), finely minced
1 teaspoon (2 g) ground cumin
½ teaspoon (1 g) ground coriander
¼ teaspoon (0.5 g) ground turmeric
8 cups (1.9 L) low-sodium vegetable or chicken broth, or water
1½ teaspoons (9 g) fine salt, plus more to taste; use less if your broth is salted
¼ teaspoon (0.5 g) freshly ground black pepper
3 tablespoons (45 ml) fresh lemon juice, plus lemon wedges for serving
2 tablespoons (8 g) chopped fresh parsley or cilantro, optional
1 tablespoon (15 ml) olive oil for drizzling, optional

Instructions

Rinse the grains and lentils. Put the lentils in a fine-mesh strainer and rinse under cool water, picking out any small stones or damaged lentils. Rinse the rice separately. This removes surface starch and dust; it does not need to be soaked. Drain both well while you prepare the vegetables.
Soften the onion and carrot. Heat 2 tablespoons olive oil in a large, heavy-bottomed pot over medium heat. Add the diced onion and carrot with a small pinch of the measured salt. Cook for 6 to 7 minutes, stirring now and then, until the onion is soft and translucent. Keep the heat moderate: browning is not necessary, and scorched onion can make the broth taste bitter.
Wake up the aromatics. Stir in the garlic, cumin, coriander, turmeric, and black pepper. Cook for about 30 seconds, just until fragrant. Keep the spices moving so the garlic does not burn. If the pot seems dry, add a tablespoon of broth or water rather than extra oil.
Simmer the soup. Add the rinsed lentils, rice, broth, and remaining salt. Stir well and bring the mixture to a gentle boil over medium-high heat. Lower the heat to maintain a steady simmer, partially cover the pot, and cook for 25 minutes. Stir every 5 to 7 minutes, scraping the bottom so the rice and lentils do not catch. The lentils should be very soft and the rice tender; if either is still firm, simmer for another 3 to 5 minutes.
Adjust the texture. Stir the soup vigorously for 30 to 60 seconds to break down some of the lentils and rice. This gives it a naturally creamy texture while leaving a little body. For a smoother soup, use an immersion blender briefly in the pot, keeping the blade submerged to prevent splashes. If the soup is thicker than you like, stir in hot water or broth, ¼ cup (60 ml) at a time.
Finish with lemon and taste. Remove the pot from the heat and stir in 3 tablespoons lemon juice. Taste and add more salt, pepper, or lemon as needed. The lemon should brighten the earthy lentils without making the soup sharply sour. Ladle into bowls and finish with chopped parsley or cilantro and a small drizzle of olive oil, if using.

Tips

Use red lentils for the expected texture. Split red lentils soften and partly dissolve as they simmer, which thickens the soup without a roux or dairy. Brown or green lentils hold their shape and take longer to cook, so they will make a more separate, less creamy soup; if substituting, cook until tender and expect to adjust the liquid and timing.
Rinse, but do not worry about perfect clarity. A quick rinse removes dust and excess starch from the rice. Draining it well helps keep the measured broth ratio predictable. If you forget to rinse, the soup will still work, though it may be slightly starchier.
Keep the simmer gentle and stir the bottom. Red lentils and rice can settle and stick as they soften. A low, steady simmer and occasional stirring are more useful than a rapid boil, which can break the rice unevenly and reduce the broth too quickly.
Season at the end as well as the start. Broths differ in saltiness, and lemon changes how salty a soup tastes. Start with less salt if you are unsure, then make the final adjustment after adding the lemon. Add lemon gradually if you prefer a mellow finish.

Serving Suggestions

Serve the soup hot in shallow bowls, with lemon wedges at the table so each person can adjust the acidity. Chopped parsley or cilantro and a little olive oil make a simple finish; a pinch of ground cumin over each bowl is another easy option. The soup is filling on its own, but warm pita, flatbread, or crusty bread is useful for scooping up the thicker lentils.

For a fuller meal, pair it with a crisp salad of cucumber, tomato, lettuce, and herbs dressed with lemon and olive oil. Pickled turnips, olives, or a small plate of sliced vegetables provide a sharp, crunchy contrast to the soft soup. If serving several people, keep extra broth or hot water nearby: the soup thickens as it sits, and a splash stirred into each portion can bring it back to a spoonable consistency.

Variations

Make it without rice: Leave out the rice and use ½ cup (95 g) extra red lentils. Begin checking the texture after about 20 minutes of simmering; the soup may need a little less broth, so add liquid gradually if it becomes too thick. This version is more distinctly lentil-forward.

Use water instead of broth: Water works well, especially when the onion and spices are given time to soften and release their aroma. Taste carefully at the end and adjust the salt, lemon, and cumin. Low-sodium broth adds savory depth, while chicken broth makes the soup non-vegetarian.

Add greens: Stir in 2 packed cups (60 g) of chopped spinach during the final 2 minutes of simmering, or add 1 cup (30 g) chopped parsley just before serving. Greens bring fresh flavor and color, but adding a large amount can mute the lemon, so taste again before serving.

Give it a gentle chile warmth: Add ¼ teaspoon (0.5 g) red pepper flakes with the cumin, or offer them at the table. For a more pronounced garlic flavor, cook one extra minced clove with the aromatics. These are optional changes rather than requirements; keep the lemon in the finish to maintain the soup’s bright character.

Storage and Reheating

Let the soup cool briefly, then transfer it to shallow, covered containers and refrigerate within 2 hours of cooking. It keeps for 3 to 4 days in the refrigerator. The rice and lentils continue to absorb broth as the soup chills, so it will be noticeably thicker the next day; this is normal rather than a sign that it has dried out.

To reheat a serving, warm it in a saucepan over medium-low heat, stirring regularly and adding broth or water a little at a time until it reaches the consistency you want. You can also microwave a covered bowl in short intervals, stirring between them. Reheat leftovers to 165°F (74°C), as measured with a food thermometer. Avoid repeatedly warming and cooling the whole pot; reheat only the portion you plan to eat.

For longer storage, freeze the cooled soup in airtight, freezer-safe containers for up to 3 months for best quality. Leave a little room at the top for expansion and label the container with the date. Thaw overnight in the refrigerator, then reheat as above; the rice may be softer after freezing, but stirring and adding liquid restore a good serving texture. Add a fresh squeeze of lemon after reheating if the flavor needs lifting.

Frequently Asked Questions

Can I make Lebanese lentil soup ahead?
Yes. Make it up to 3 or 4 days ahead and refrigerate it promptly in covered containers. It will thicken as it sits, so reheat gently with broth or water and taste for salt and lemon before serving. You can also freeze portions for up to 3 months.

Do I need to soak the red lentils?
No. Red lentils cook quickly and soften during the simmer, so rinsing is enough. Soaking is unnecessary for this recipe and can make the lentils cook down faster than the rice, leaving you with a thicker, less even texture.

Can I use brown or green lentils instead?
You can, but the result will be different. Brown and green lentils stay firmer and generally take longer to become tender, while the rice may finish first. For the closest texture and timing, use split red lentils; if you substitute, simmer until the lentils are tender and add broth as needed.

Why did my soup turn out too thick?
Red lentils and rice absorb liquid as they cook and continue doing so after cooking, so thickness is common. Stir in hot broth or water gradually until it is as loose as you like, then adjust the salt and lemon. If it is too thin, simmer uncovered for a few minutes, stirring often.

Can I make this soup vegan or gluten-free?
It is vegan when made with vegetable broth or water and olive oil, and the listed ingredients are naturally gluten-free. Check packaged broth and spices if you need to avoid gluten, since ingredients and processing practices can vary. Chicken broth makes the recipe non-vegetarian, but it does not change the cooking method.
