The broth in this soup is thick and savory, clinging to the firm, peppery lentils and softened chunks of carrot. It is a reliable meal for cold weather because it stays hearty without feeling overly heavy.
Preparing the root vegetables in uniform, half-inch cubes allows them to soften at the same rate as the lentils. This prevents the carrots from becoming mushy while the lentils are still hard.
This dish shares a similar comforting profile to Hearty Chunky Zucchini Soup With White Beans Healthy Vegan Vegetable Soup, making it a great addition to a rotation of plant-based, nutrient-dense lunches.
Ingredients |
French green lentils provide the structure of the soup. Unlike red lentils, these hold their shape after simmering, giving the dish a satisfying chew.
Carrots and parsnips add a natural, earthy sweetness that balances the saltiness of the broth.
Celery creates a savory base layer of flavor, essential for a deep, aromatic soup.
Garlic adds a pungent, sharp note that mellows into a sweet richness as it cooks in the olive oil.
Vegetable broth acts as the liquid medium, extracting flavors from the vegetables and hydrating the lentils.
Fresh thyme brings a woody, herbal quality that complements the earthiness of the root vegetables.
How to Make It |
- Sauté the aromatics: Heat olive oil in a large pot over medium heat. Add the diced carrots, celery, and parsnips, cooking for about 6 to 8 minutes until the edges begin to soften.
- Add garlic and herbs: Stir in the minced garlic and fresh thyme. Cook for 1 minute until the garlic is fragrant but not browned.
- Simmer the lentils: Pour in the rinsed lentils and vegetable broth. Increase the heat to bring the liquid to a boil, then immediately reduce to a low simmer.
- Cook until tender: Cover the pot and simmer for 30 to 40 minutes. The lentils should be tender but still hold their shape.
- Finish and season: Stir in a splash of lemon juice or apple cider vinegar at the end to brighten the flavors. Season with salt and black pepper to taste.
- ●1Rinse the lentils: Place the lentils in a fine-mesh strainer and rinse under cold water to remove any dust or small debris before adding them to the pot.
- ●2Avoid early salting: Add the majority of your salt at the end of the cooking process. Salting too early can sometimes prevent the lentil skins from softening properly.
- ●3Adjust the thickness: If the soup becomes too thick as it sits, stir in a small amount of hot water or extra broth before reheating.
Storage and Reheating |
Store the soup in an airtight container in the refrigerator for up to five days. The flavors often deepen and improve after a day of resting.
When reheating on the stove, add a tablespoon of water to loosen the consistency, as the lentils will continue to absorb liquid while stored.
