Classic Hearty Lentil Soup
A comforting and robust lentil soup, brimming with earthy lentils and aromatic vegetables, simmered to perfection in a savory broth for a truly satisfying meal.
For 6 servings
Prepare Vegetables: Wash and chop the onion, carrots, and celery into small, uniform pieces (about 1/2 inch dice). Mince the garlic. Rinse the brown lentils thoroughly under cold water.
Sauté Aromatics: Heat the olive oil in a large pot or Dutch oven over medium heat. Add the chopped onion, carrots, and celery. Sauté for 8-10 minutes, stirring occasionally, until the vegetables have softened and the onion is translucent. Add the minced garlic and cook for another 1 minute until fragrant.
Combine Ingredients: Stir in the rinsed brown lentils, vegetable broth, undrained diced tomatoes, bay leaves, and dried thyme. Bring the mixture to a boil over medium-high heat.
Simmer: Once boiling, reduce the heat to low, cover the pot, and let it simmer for 40-50 minutes, or until the lentils are tender and the soup has thickened to your desired consistency. Stir occasionally to prevent sticking.
Season: Remove the pot from the heat. Carefully remove and discard the bay leaves. Season the soup with salt and freshly ground black pepper to taste. Adjust seasonings as needed.
Serve: Ladle the hot soup into bowls. Garnish each serving with fresh chopped parsley. Serve immediately, perhaps with a side of crusty bread.
What to keep in mind.
4 tips from the recipe — small details that make a real difference to the final dish.
- 1Don't forget the bay leaves: While seemingly small, bay leaves impart a crucial, subtle aromatic depth that defines the classic lentil soup flavor. Remember to remove them before serving.
- 2Adjust consistency: If you prefer a thicker soup, mash a portion of the lentils against the side of the pot with a spoon or use an immersion blender for a few pulses. For a thinner soup, add a little more vegetable broth or water.
- 3Flavor layering: Sautéing the aromatics (onion, carrot, celery, garlic) until well softened before adding liquids builds a strong flavor base for the entire soup.
- 4Make ahead: Lentil soup tastes even better the next day as the flavors meld. It also freezes exceptionally well for convenient future meals.
