A steaming bowl of lentil soup with carrots and celery, topped with fresh parsley, with crusty bread on the side.
This lentil soup is thick, cozy, and packed with simple, comforting flavor. You get tender lentils, sweet carrots, and a savory broth that tastes like it simmered all day (but it doesn’t). This lentil soup recipe is perfect for meal prep, easy weeknight dinners, and chilly days.
Introduction
Lentil soup is one of those “always a good idea” meals. It’s budget-friendly, filling, and it tastes even better the next day. The standout trick is sautéing the veggies until they’re soft and sweet before adding the broth. That builds a deeper flavor fast.
If the soup gets too thick, just whisk in a splash of broth until it’s silky. It’s a forgiving, cozy pot of goodness.

Ingredients for Lentil Soup
- Olive oil (1 tablespoon): For sautéing.
- Onion, diced (1 medium): Sweet base flavor.
- Carrots, diced (1 cup): Adds sweetness.
- Celery, diced (1 cup): Savory balance.
- Garlic, minced (4 cloves): Big flavor.
- Dry brown or green lentils (1 1/2 cups): Hold their shape; avoid red lentils here (they get mushy fast).
- Diced tomatoes (1 can, 14.5 ounces): Adds body and tang; you can skip if you prefer.
- Vegetable broth, low-sodium (6 cups): Low-sodium helps you control seasoning.
- Bay leaf (1): Cozy flavor.

- Salt (1 teaspoon) and black pepper (1/2 teaspoon): Adjust at the end.

Lentil Soup Recipe Step-by-Step
- 1. Sauté: Heat oil in a large pot over medium heat. Cook onion, carrots, and celery 6–8 minutes until softened.
- 2. Bloom: Add garlic, cumin, and thyme. Stir 30 seconds until fragrant.
- 3. Simmer: Add lentils, tomatoes, broth, and bay leaf. Bring to a boil, then reduce to a steady simmer.
- 4. Cook: Simmer 25–35 minutes, stirring occasionally, until lentils are tender.
- 5. Adjust: Remove bay leaf. If you want a thicker soup, mash a few spoonfuls of lentils against the pot and stir.
- 6. Finish: Stir in lemon juice. Taste and add more salt and pepper if needed.
- 7. Serve: Ladle into bowls and top with parsley. If it looks too thick after sitting, whisk in a splash of broth until it’s silky.
Tips for Perfect Lentil Soup
- Rinse lentils and pick out any small stones.
- Sauté veggies first for deeper flavor.
