Green lentil tomato soup uses dry lentils, chopped vegetables, and a combination of broth and water for a generous pot of soup. The lentils soften during the simmer and give the broth body. Lemon juice and parsley are added near the end for a fresh finish.
Use a six-quart pot with room for the lentils to expand and the soup to bubble gently. Two cups of dry lentils make a substantial batch, approximately eight servings. This is a tomato-and-herb version, distinct from a potato-and-cheese soup or a curry-seasoned lentil pot.

Why This Recipe Works
Green lentils generally hold some shape while becoming tender inside. Green lentil tomato soup is therefore spoonable without needing a full puree. The carrots and celery are sliced thinly so they finish softening alongside the lentils rather than remaining hard chunks.
The amount of water is adjustable because lentil age, simmer strength, and lid position change absorption and evaporation. Begin with three cups water in addition to the measured broth. The remaining cup is a correction allowance, not automatically an extra full addition after cooking.
Ingredients for Green Lentil Tomato Soup
For green lentil tomato soup, sort dry lentils for small stones or damaged pieces and rinse them well. Use ordinary green lentils, not split red lentils that soften into a different texture. No overnight soaking is required for this stated method.
Tomato paste cooks briefly with the aromatics before crushed tomatoes are added. Italian seasoning, paprika, cumin, bay leaves, and black pepper supply flavor. Low-sodium vegetable broth makes it easier to season at the end. Lemon juice brightens the cooked soup but is not a substitute for the tomatoes or a preservation step.
Soup
- 2 tablespoons olive oil
- 1 medium yellow onion (Diced)
- 3 medium carrots (Thinly sliced)
- 2 stalks celery (Thinly sliced)
- 1 tablespoon tomato paste
- 3 cloves garlic (Minced)
- 1 teaspoon Italian seasoning
- 1 teaspoon paprika
- 1/2 teaspoon ground cumin
- 2 bay leaves
- 2 cups dry green lentils (Sorted and rinsed)
- 14.5 ounces canned crushed tomatoes
- 4 cups low-sodium vegetable broth
- 3–4 cups water (Start with 3 cups; add remaining cup only as needed)
- 1/4 teaspoon black pepper
- to taste fine salt
- 1 tablespoon lemon juice
- 2 tablespoons chopped parsley
How to Make Green Lentil Tomato Soup
Warm olive oil in the pot over medium heat. Cook onion, carrots, and celery for six to eight minutes, stirring until they begin to soften. Add garlic, tomato paste, and dried seasonings and stir for about a minute without scorching the paste.
Add rinsed lentils, crushed tomatoes, broth, the first three cups water, bay leaves, and pepper. Bring to a gentle boil, then reduce to a simmer and partly cover. Cook green lentil tomato soup for thirty-five to fifty minutes, stirring occasionally and checking that the bottom is not drying.
Taste several lentils for a tender center. Older lentils can need longer, especially in a tomato-rich liquid. If the soup becomes thick before they soften, add reserved water a quarter cup at a time and continue. Remove bay leaves, add lemon juice and parsley, and taste before adding salt. For a thicker body, mash a ladleful of cooked lentils against the pot side rather than blending the entire hot batch.
How to Serve
Serve green lentil tomato soup hot in eight moderate bowls, stirring before portioning so the lentils do not all settle to the bottom. Bread or a fresh salad makes a useful accompaniment. The recipe does not require cream or cheese to complete it. Keep any extra pot covered and hot for immediate serving, or divide it promptly for refrigeration.
Storage
Refrigerate green lentil tomato soup in shallow containers within two hours, or one hour above 90°F. Use within three to four days. It thickens as it stands; loosen reheated portions with water and heat to 165°F. Freeze for up to three months for quality, leaving headroom for expansion, and thaw in the refrigerator before reheating.
The FDA safe food handling guidance explains prompt refrigeration and temperature checks for perishable foods.
Tips and Variations
For green lentil tomato soup, let the simmer stay gentle rather than allowing a hard uncovered boil. Rapid evaporation can make a still-firm batch look finished simply because there is little liquid left. Add water according to the grain texture, not only the appearance of the surface.
Remove both bay leaves before serving. If your lentils remain unusually firm, allow additional simmering with enough liquid instead of serving them by the timer. Do not add baking soda to force softening here; that would change the flavor and texture of the measured recipe.
Frequently Asked Questions
Does green lentil tomato soup need soaked lentils?
No. Sort and rinse the dry green lentils, then simmer them as directed until tender.
Can I use red lentils?
They break down faster and produce a different texture. The timing here is written for green lentils.
Why is it thicker the next day?
The lentils continue absorbing liquid during storage. Add a little water while reheating and check for 165°F.
Is the full extra cup water required?
No. Start with three cups water and add some of the reserved fourth cup only if needed.
Can I freeze portions?
Yes. Cool promptly, leave expansion room in freezer containers, and freeze for up to three months for quality.
