• to tastesalt and freshly ground black pepper
• 30 ml (2 tablespoons)fresh lemon juice
• to tastefresh parsley, chopped, for garnish
• to taste (optional)extra-virgin olive oil for drizzling

Instructions

1. 1

   Soften the vegetables

   Heat the olive oil in a large pot or Dutch oven over medium heat. Add the onion, carrots and celery, and cook, stirring now and then, for about 7–8 minutes, until softened and the onion is translucent.

2. 2

   Toast the spices

   Stir in the garlic, cumin and smoked paprika. Cook for 1 minute, stirring continuously, until fragrant.

3. 3

   Add the lentils

   Add the rinsed lentils, vegetable broth and bay leaf, then stir and scrape up any browned bits from the base of the pot. The method also refers to diced tomatoes and their juices, but tomatoes are not included in the ingredient list, so their quantity is unspecified.

4. 4

   Simmer until tender

   Bring the soup to a boil, then turn the heat to low, cover and simmer gently for 30–35 minutes, until the lentils are tender but still hold their shape.

5. 5

   Finish and season

   Take out and discard the bay leaf, then stir in the lemon juice. Taste and season generously with salt and pepper. If the soup is too thick, add a splash of broth or water to loosen it.

6. 6

   Serve the soup

   Ladle into bowls and top with chopped parsley and a drizzle of olive oil, if using. Serve straight away with crusty bread for dipping.

What is lentil soup?

Lentil soup is a simple, adaptable dish found in many food traditions; this version takes a familiar American home-cooking approach, using a vegetable base, broth and pantry spices. Brown or green lentils give it a hearty texture while keeping their shape as they simmer.

Aromatic vegetables and cumin build savoury depth, while lemon added at the end lifts the finished bowl. One detail to check before cooking: the method mentions diced tomatoes, but the supplied ingredient list does not include them or give a quantity.

Nutrition and macros by portion

The nutrition label shows one serving as written: 320 calories, 0g protein, 0g carbs, 0g fat.

The lentils provide most of the carbohydrates and plant protein, while olive oil contributes the main fat. Vegetables and broth add volume and flavour; serve the soup with a green salad or other vegetables for a balanced plate.

Build a flavourful base

Vegetables first: cook the onion, carrots and celery until softened rather than rushing straight to the broth. This gives them time to become tender and sweet.

Spices next: add the garlic, cumin and smoked paprika only after the vegetables have softened. Stir for the stated minute so the spices become fragrant without letting the garlic burn.

Choose and rinse the lentils

Brown or green: either variety suits this recipe and generally keeps some shape during a gentle simmer. Rinsing removes surface dust before the lentils go into the pot.

Check the packet: lentils can vary, so use the recipe's tenderness cue rather than relying only on the clock. The aim is soft lentils that have not collapsed into a purée.

Keep the simmer gentle

Steady heat: once the soup reaches a boil, lower the heat and cover the pot for the 30–35-minute simmer. A quiet simmer cooks the lentils evenly without making the vegetables churn apart.

Check near the end: start testing around the 30-minute mark, then continue until the lentils are tender. If the soup thickens more than you like, loosen it with a splash of broth or water.

Finish with lemon and herbs

Lemon last: stir in the juice after the lentils have cooked, then taste and adjust the salt and pepper. Adding it at the end keeps its fresh, bright character noticeable.

Fresh garnish: chopped parsley adds a clean herbal note, and the optional olive-oil drizzle gives each serving a richer finish. Add both just before serving.

Serving ideas

Bread alongside: crusty bread is suggested for dipping and makes the soup feel more substantial. Put it on the table separately so diners can choose their portion.

A fresh side: serve with a crisp green salad or simply dressed vegetables to contrast with the warm, soft lentils. Keep extra lemon and parsley available for anyone who wants a brighter bowl.

Recipe notes & tips

• Rinse the lentils before adding them to the pot.
• Keep the heat low after bringing the soup to a boil.
• Begin checking the lentils for tenderness at 30 minutes.
• Add broth or water gradually if the soup becomes too thick.
• Taste for salt and pepper after stirring in the lemon juice.
• Check the recipe details for the missing tomato quantity before deciding whether to include tomatoes.

Variations

• Add the listed tomatoes: include diced tomatoes with their juices as the method directs, but note that no quantity is provided.
• Use another lentil colour: choose brown or green lentils, as specified, and check for tenderness as they cook.
• Add leafy greens: stir in a handful of spinach near the end and cook until wilted.
• Make it more lemony: serve with extra lemon juice at the table.
• Boost the herbs: add extra chopped parsley when serving.

Common mistakes to avoid

• Skipping the vegetable-softening stage: cook the onion, carrots and celery for 7–8 minutes so they soften before the broth goes in.
• Burning the garlic: stir it with the spices for just 1 minute and keep it moving.
• Boiling the soup throughout: lower the heat after it boils, then simmer gently with the lid on.
• Overcooking the lentils: check them from 30 minutes and stop when tender but still holding their shape.
• Adding too much liquid at once: loosen a thick soup with broth or water a splash at a time.
• Guessing the tomato amount: the method mentions tomatoes but the ingredient list omits them, so check the source recipe if you want to use them.

How to store

Cool leftovers and refrigerate in a covered container for up to 3–4 days. Reheat gently in a saucepan, stirring occasionally; add a little water or broth if the soup has thickened. The soup can also be frozen in portions for up to 3 months.
