Ingredients
For approximately 6 servings, you will need:
- 1½ cups dried green or brown lentils
- 2 tablespoons extra-virgin olive oil
- 1 medium yellow onion, finely chopped
- 3 cloves garlic, minced
- 2 medium carrots, diced
- 2 celery stalks, diced
- 1 can (400 g / 14 oz) diced tomatoes
- 6 cups vegetable broth or low-sodium chicken broth
- 1 teaspoon ground cumin
- 1 teaspoon dried oregano
- ½ teaspoon smoked paprika
- 1 bay leaf
- ½ teaspoon salt, plus more to taste
- ¼ teaspoon freshly ground black pepper
- 2 cups chopped fresh spinach or kale, optional
- Juice of 1 lemon
- 2 tablespoons fresh parsley, chopped
For serving:
- Extra-virgin olive oil
- Fresh parsley
- Lemon wedges
- Optional plain Greek yogurt
Preparing the Lentils
Start by sorting through the dried lentils and removing any small stones or damaged lentils.
Place them in a fine-mesh strainer and rinse thoroughly under cool running water. Rinsing removes dust and debris and helps ensure the finished soup has a clean flavor.
Unlike some other dried legumes, lentils generally do not require overnight soaking. This makes them particularly convenient when you want to prepare a healthy meal without much advance planning.
Set the rinsed lentils aside while you prepare the vegetables.
Sautéing the Vegetables
Place a large heavy-bottomed pot or Dutch oven over medium heat.
Add the olive oil and allow it to warm gently. Add the chopped onion, carrots, and celery.
Cook the vegetables for approximately 5–7 minutes, stirring occasionally. The onion should become soft and translucent, while the carrots and celery should begin to soften.
Add the minced garlic and cook for another 30–60 seconds. Be careful not to burn the garlic because it can become bitter.
This initial sautéing step builds the foundation of the soup. Cooking the vegetables in olive oil allows their natural flavors to develop before the liquid is added.
Adding the Herbs and Spices
Add the cumin, oregano, smoked paprika, black pepper, and salt to the vegetables.
Stir for approximately 30 seconds.
Heating the spices briefly in the olive oil helps release their aromas and gives the finished soup a deeper flavor.
If you prefer a spicier soup, add a small pinch of red pepper flakes at this stage.
Cooking the Soup
Add the rinsed lentils to the pot along with the diced tomatoes and vegetable or chicken broth.
Add the bay leaf and stir everything together.
Increase the heat and bring the soup to a gentle boil.
Once it begins boiling, reduce the heat to low or medium-low. Cover the pot partially and allow the soup to simmer for approximately 30–40 minutes.
Stir occasionally and check the lentils toward the end of the cooking time.
The exact cooking time depends on the type and age of the lentils. They should become tender but should not necessarily completely disintegrate.
If the soup becomes thicker than you prefer, add a little additional broth or water.
Adding Greens
Once the lentils are tender, remove the bay leaf.
If using spinach or kale, add it to the pot during the final few minutes of cooking.
Fresh spinach wilts very quickly, usually within one to two minutes. Kale takes slightly longer and can be simmered for several minutes until tender.
Adding greens provides additional color and texture while complementing the earthy flavor of the lentils.
Taste the soup and adjust the salt and pepper as needed.
Finishing With Lemon
One of the most important finishing touches is fresh lemon juice.
Turn off the heat and stir in the juice of one lemon. Taste the soup and add more lemon juice if you prefer a brighter, more acidic flavor.
The lemon helps balance the earthy lentils and rich olive oil while making the vegetables and herbs taste fresher.
Avoid adding all the lemon juice at once if you are unsure about the desired acidity. Start with less and adjust according to taste.
Serving the Soup
Ladle the hot soup into bowls and garnish with freshly chopped parsley.
Add a small drizzle of extra-virgin olive oil and serve with a lemon wedge on the side.
For a creamy contrast, add a spoonful of plain Greek yogurt to each serving. The cool yogurt works particularly well with the warm, savory soup.
Serve with whole-grain bread, toasted pita, or a simple Mediterranean salad for a complete meal.
Tips for the Best Lentil Soup
Choose green or brown lentils because they generally hold their shape well during cooking. Red lentils can also be used, but they cook more quickly and create a much softer, thicker soup.
Use low-sodium broth if possible so you can control the salt level yourself.
Fresh lemon juice is preferable to bottled lemon juice because it provides a brighter and fresher flavor.
Do not skip the vegetable sautéing step. Although it adds a few minutes to the recipe, it develops much more flavor than simply boiling all the ingredients together.
For a thicker soup, mash a small portion of the cooked lentils and vegetables against the side of the pot with a spoon or use an immersion blender briefly. Avoid blending the entire soup if you want to retain some texture.
Variations
There are many ways to customize Mediterranean Lentil Soup.
For a tomato-rich version, increase the amount of diced tomatoes or add a spoonful of tomato paste while sautéing the vegetables.
For additional vegetables, add zucchini, bell peppers, potatoes, or chopped tomatoes.
If you enjoy stronger Mediterranean flavors, add fresh thyme, rosemary, coriander, or a little chopped fresh mint.
For a creamy variation without adding dairy, blend a portion of the soup until smooth and stir it back into the pot.
You can also add cooked chickpeas for additional texture and variety.
Storage and Meal Preparation
This soup is excellent for meal preparation because its flavor often becomes even better after resting.
Allow leftovers to cool before transferring them to airtight containers. Refrigerate and enjoy within several days.
The soup can also be frozen in individual portions. Leave some space at the top of each container because the soup expands as it freezes.
When reheating, warm it gently on the stovetop or in the microwave. Add a little water or broth if the soup has thickened during storage.
Add fresh lemon juice and parsley after reheating to refresh the flavor.
