Lebanese Lentil Soup Recipe

I find so much comfort in making a big pot of soup on a chilly evening, especially when it’s as nourishing as this lebanese lentil soup recipe.

This hearty soup delivers deep comfort and flavor in under 30 minutes, perfect for busy families, and the secret is actually a quick, aromatic spiced oil drizzle that elevates everything. It’s a budget-friendly meal that tastes like it took all day to make. My family requests this recipe constantly, especially on chilly evenings when we need something quick and satisfying. This version of lebanese lentil soup includes fresh spinach and vermicelli pasta, making it a complete meal that’s both delicious and incredibly easy to prepare.

Ingredients

• 250 g (1 ¼ cups) red lentils, rinsed: Use dry red lentils, as they cook down quickly and provide a creamy texture. Rinse thoroughly before cooking to remove starch and debris, ensuring a cleaner flavor. Avoid split green or brown lentils; they won’t break down enough for the desired creamy consistency.
• 1.5 L (6 cups) vegetable broth and 500 ml (2 cups) water: Use a quality low-sodium vegetable broth to control the overall salt level in the soup. The combination of broth and water provides sufficient liquid for the lentils to cook fully and create a thick base. Add more liquid during simmering if the soup becomes too thick.
• 1 medium yellow onion, finely diced; 4 cloves garlic, minced; 30 ml (2 tablespoons) olive oil, for sautéing: Sautéing the onion until translucent forms the foundation of flavor for the soup. Mince the garlic finely to release maximum aroma and integrate seamlessly into the soup base. Use a standard olive oil for cooking (not extra virgin, which burns at lower temperatures) for the sauté step.
• 100 g (3.5 oz) fresh spinach, roughly chopped; 50 g (½ cup) short vermicelli pasta, broken into small pieces: Fresh spinach adds nutritional value and color; roughly chop before adding to ensure even distribution. Vermicelli pasta adds heartiness; break it into small pieces for easy eating (or swap for small rice pieces). Add greens at the end of cooking to preserve their bright color and texture.
• 60 ml (¼ cup) fresh lemon juice; 5 g (1 teaspoon) fine sea salt; 2 g (½ teaspoon) freshly ground black pepper: Fresh lemon juice brightens the flavor profile and cuts through the richness of the lentils. Adjust salt and pepper at the end based on the broth and personal preference. Always use fresh lemon juice, not bottled juice, for the best result in this lebanese lentil soup recipe.
• 60 ml (4 tablespoons) extra virgin olive oil, for infusion; 5 g (1 teaspoon) ground sumac; 5 g (1 teaspoon) za’atar spice blend: Use high-quality extra virgin olive oil for the finishing drizzle to add a fruity, pungent note. Sumac provides a tart, lemon-like flavor and a rich red color. Za’atar is a blend typically containing oregano, thyme, sesame seeds, and sumac; ensure your blend is fresh for maximum aroma.
• 15 g (¼ cup) fresh parsley or cilantro, finely chopped, for garnish: Fresh herbs add a final layer of freshness and color. Use flat-leaf parsley for a traditional garnish, or cilantro if preferred (it has a stronger flavor). Chop just before serving to maximize vibrant appearance and flavor.

Instructions

1. Rinse the red lentils thoroughly under cold running water until the water runs clear. Drain well. This removes starch and any potential impurities, ensuring a cleaner final soup texture. If skipping this step, the soup may be overly starchy or have a cloudy appearance. Ensure the lentils are fully drained to maintain proper liquid ratios in the pot.
2. In a large, heavy-bottomed pot or Dutch oven, heat 30 ml (2 tablespoons) of olive oil over medium heat. Add the diced onion and sauté for 5-7 minutes, until softened and translucent. Add the minced garlic and cook for another 1-2 minutes until fragrant, being careful not to brown it. Sautéing develops the base flavor; ensure the onions are soft before adding garlic. Garlic burns easily; cook only until fragrant to avoid bitterness in the soup base.
3. Add the rinsed lentils, vegetable broth, and water to the pot. Bring the mixture to a boil, then reduce the heat to low, cover, and simmer for 15-20 minutes, or until the lentils are tender and have mostly broken down. Stir occasionally to prevent sticking. Lentils will absorb a lot of liquid during simmering; stir occasionally to prevent scorching at the bottom of the pot. The goal is for the lentils to disintegrate slightly, creating a thick, creamy texture for this healthy lebanese lentil soup.
4. Stir in the chopped fresh spinach and broken vermicelli pasta. Continue to simmer, uncovered, for another 5-7 minutes, or until the spinach has wilted and the vermicelli is cooked through. The soup should be thick but still pourable; add a splash more water or broth if it becomes too thick. The vermicelli will cook quickly in the hot liquid; check for al dente texture. Adding spinach late keeps its bright green color and nutritional value intact. If the soup becomes too thick at this stage, simply add more hot broth or water to reach your desired consistency.
5. Remove the soup from the heat. Stir in the 60 ml (¼ cup) of fresh lemon juice, 5 g (1 teaspoon) of salt, and 2 g (½ teaspoon) of black pepper. Taste and adjust seasoning as needed. Lemon juice should be added at the end, as boiling it can diminish its bright flavor. Adjust seasoning to compensate for the specific saltiness of your broth and personal preference. The salt content can vary significantly between different brands of broth, so always taste before serving.
6. While the soup finishes cooking, prepare the spiced oil. In a small, heatproof saucepan, gently warm 60 ml (4 tablespoons) of extra virgin olive oil over low heat. Once warm (not smoking), remove from heat and stir in 5 g (1 teaspoon) of ground sumac and 5 g (1 teaspoon) of za’atar spice blend. Let the spices infuse in the oil for 2-3 minutes. Gently warming the oil releases the full aroma of the spices without burning them. Do not let the oil smoke, as this will result in a bitter flavor profile.
7. Ladle the hot lebanese lentil soup into individual shallow ceramic bowls. Carefully spoon a generous drizzle of the warm, spiced sumac-za’atar oil over the center of each serving, allowing it to spread and create a glossy, reddish-brown swirl. Garnish with a sprinkle of fresh chopped parsley or cilantro for a vibrant contrast. Serving individually ensures each bowl gets a beautiful drizzle of the spiced oil. The finishing drizzle elevates a simple soup into a restaurant-quality dish. I find that a generous amount of fresh parsley truly brightens the final dish.

Meal Prep and Storage Tips

This soup is great for making ahead, as the flavors develop even further overnight. Here are some easy tips for storage and reheating.

• Make-Ahead Instructions: The soup base (without the pasta) can be made up to 3 days ahead and stored in an airtight container in the fridge. The flavor develops even more overnight, and you can add the spinach and vermicelli when reheating. If pasta is added too soon, it will absorb all the liquid and become mushy upon reheating.
• Freezing Instructions: Freeze leftover lebanese lentil soup for up to 3 months in freezer-safe containers. Leave headspace for expansion as the soup freezes. Note that the vermicelli may change texture slightly after freezing and thawing, but the flavor remains excellent.
• Reheating: Reheat gently on the stovetop over medium-low heat. If the soup has thickened significantly, add a splash of broth or water to reach the desired consistency. Taste and adjust seasoning after reheating.

Recipe Variations for Dietary Needs and Flavor

Protein Boost

Stir in shredded rotisserie chicken or ground lamb during the last 10 minutes of simmering to make it heartier. For a plant-based option, add a can of drained and rinsed chickpeas along with the spinach.

Vegetable Additions

For extra flavor and nutrients, sauté a diced carrot and celery stalk along with the onion at the beginning of the recipe. You can also add other quick-cooking greens like kale or Swiss chard instead of spinach.

Make it Gluten-Free

Replace the vermicelli pasta with gluten-free pasta (adjust cooking time as needed) or use rice for a gluten-free grain option. Make sure to check that your vegetable broth is certified gluten-free.

Serving Suggestions and Pairings

Serve this hearty soup with warm pita bread or crunchy crusty bread for dipping. A side of toasted sourdough with olive oil is also perfect for soaking up the broth. For a truly authentic experience, serve alongside a light green salad or some sliced cucumbers and tomatoes.

FAQs

Why did my soup turn out too thick?

Red lentils break down completely as they cook and absorb a lot of liquid. If your lebanese lentil soup is too thick, simply stir in more hot broth or water until it reaches your preferred consistency. When I make a big batch, I always keep extra broth on hand for reheating.

What exactly is sumac and za’atar?

Sumac is a spice derived from dried berries, providing a tart, lemony flavor. Za’atar is a spice blend often containing thyme, oregano, sesame seeds, and sumac. Both are essential for the traditional flavor profile of this lebanese lentil soup recipe.

Can I use green lentils instead of red lentils?

Green lentils take longer to cook and hold their shape, so they will not result in the creamy texture intended for this soup. Stick to red lentils or split yellow lentils for this lebanese lentil soup recipe.

Can I make this soup without the spiced oil?

Yes, the soup base is still delicious on its own, but the spiced oil adds a critical layer of traditional flavor and visual appeal. The recipe is highly recommended with it, especially if you’re looking for authentic flavor.

Can this recipe be made vegetarian/vegan?

Yes, this lebanese lentil soup recipe is naturally vegetarian and vegan as written, using vegetable broth and plant-based ingredients. It’s a perfect healthy eating option for family dinners.
