Ingredients

Main Ingredients

2 tablespoons olive oil
1 medium onion, finely chopped
2 cloves garlic, minced
3 carrots, peeled and diced
2 celery stalks, diced
1 ½ cups dry green or brown lentils, rinsed
6 cups (1.5 liters) vegetable or chicken broth
1 teaspoon dried thyme (or 1 tablespoon fresh)
1 bay leaf
Salt and freshly ground black pepper, to taste
1 teaspoon ground cumin (optional for depth)
2 tablespoons chopped fresh parsley
1 tablespoon lemon juice (optional, for brightness)

Optional Additions

1 diced potato or parsnip for added body
½ teaspoon smoked paprika for extra warmth
1 cup chopped kale or spinach added at the end
A drizzle of olive oil or a sprinkle of Parmesan for serving

Instructions

1. Sauté the Aromatics

In a large soup pot, heat olive oil over medium heat. Add the chopped onion and cook for 4–5 minutes until softened and translucent. Stir in the minced garlic, carrots, and celery. Cook another 5 minutes, stirring often, until the vegetables start to release their aroma and become slightly tender.

2. Add the Lentils and Herbs

Add the rinsed lentils to the pot and stir well to coat them in the oil and vegetable mixture. Sprinkle in the thyme, cumin (if using), salt, and pepper. Stir to blend the flavors before adding the broth.

3. Simmer the Soup

Pour in the vegetable or chicken broth, add the bay leaf, and bring the soup to a gentle boil. Once boiling, reduce the heat to low and let it simmer uncovered for 30–35 minutes, stirring occasionally. The lentils should become soft and the vegetables tender.

If you prefer a thicker consistency, let the soup cook a few minutes longer to allow some lentils to break down naturally. For a smoother texture, mash a small portion with a spoon or blend briefly with an immersion blender.

4. Add Fresh Herbs and Finish

Once the lentils are fully cooked, remove the bay leaf. Stir in chopped fresh parsley and a splash of lemon juice to brighten the flavors. Taste and adjust seasoning with additional salt and pepper if needed.

5. Serve Warm

Ladle the soup into bowls and drizzle each serving with a bit of olive oil. Garnish with more parsley or a sprinkle of grated cheese if desired. Serve with crusty bread, pita, or a side salad for a balanced, filling meal.

Tips for Success

Rinse lentils thoroughly: This removes dust and ensures even cooking.
Avoid over-salting early: Lentils absorb liquid as they cook—season more at the end.
Use the right lentils: Green or brown lentils hold their shape best; red lentils yield a softer, creamier texture.
Simmer gently: Boiling too hard can cause lentils to burst and turn mushy.
Add greens last: Spinach or kale should go in just before serving to stay vibrant.

Flavor Variations

Mediterranean Style: Add diced tomatoes, oregano, and a touch of rosemary.
Indian-Inspired: Stir in curry powder, turmeric, and coconut milk.
Smoky Lentil Soup: Use smoked paprika and roasted vegetables.
Winter Herb Blend: Use sage, thyme, and rosemary for a richer flavor.
Spicy Version: Add chili flakes, jalapeño, or cayenne pepper for a kick.

Serving Suggestions

Serve with toasted bread, naan, or cornbread for dipping.
Add a side of roasted vegetables or grain salad for a hearty meal.
For a light lunch, pair with a fresh garden salad and lemon vinaigrette.
Top with Greek yogurt or crème fraîche for creaminess.

Storage & Reheating

Refrigerate: Store leftovers in an airtight container for up to 5 days.
Freeze: Cooled soup can be frozen for up to 3 months. Thaw overnight in the fridge before reheating.
Reheat: Warm gently on the stovetop over medium heat, adding a little water or broth if it thickens too much.
