Instructions

1. 1

   Soften the onion

   Heat the olive oil and butter in a soup pot or Dutch oven over a medium heat. Once the butter has melted, add the onion and cook for 5–7 minutes, until softened and lightly browned.

2. 2

   Cook the spices

   Stir in the garlic, cumin, paprika, cayenne, turmeric, saffron if using, and flour. Cook for about 1 minute, stirring almost constantly.

3. 3

   Add the stock

   Pour in the stock and stir well, dissolving the flour and scraping the browned bits from the bottom of the pot.

4. 4

   Simmer the lentils

   Add the lentils and tomato purée, then add the bay leaf. Raise the heat and bring the soup to the boil, then lower it to a rapid simmer. Cook uncovered for about 10–15 minutes, stirring occasionally, until the lentils are tender.

5. 5

   Finish the soup

   Remove and discard the bay leaf, then stir in the evaporated milk. Simmer for a few minutes, until warmed through. Blend with a hand-held blender to your preferred consistency, or leave the lentils whole for a more rustic soup. Stir in the chopped coriander and season generously with salt and pepper.

What is spicy lentil soup?

Lentil soup is made in many food traditions, and this version takes a simple, American-style approach to an everyday bowl: dried lentils, stock and pantry spices cooked together in one pot. Cumin, paprika, cayenne and turmeric give it warmth, while saffron adds a distinctive aroma if you have it.

Red lentils soften quickly and help thicken the broth as they cook. Evaporated milk and a brief blend make the finished soup creamy without losing the option of a more textured bowl.

Nutrition and macros by portion

The nutrition label shows one serving as written: 365 calories, 20g protein, 50g carbs, 9g fat.

The lentils supply most of the carbohydrates and a substantial share of the protein, while the olive oil, butter and evaporated milk contribute much of the fat. For a balanced plate, serve a bowl with a side salad or extra vegetables.

Build flavour in the pot

Onion: Give it the full 5–7 minutes to soften and pick up a little colour; this creates a savoury base for the spices.

Spices and flour: Stir continuously as they cook for about a minute so the flour disperses and the spices become fragrant without catching.

Choose your stock

Vegetable stock keeps the soup meat-free, while chicken stock gives it a fuller savoury flavour. Either works with the lentils and spices.

Scrape the base of the pot as you stir in the stock. This loosens the browned onion and spice residue and helps the flour blend into the liquid.

Watch the lentils

Red lentils are the quick-cooking choice here, but their exact cooking time can vary. Start checking around 10 minutes and simmer up to 15 minutes, until they are tender.

Stir occasionally while the soup simmers, especially along the bottom of the pot, where lentils can settle and stick.

Pick a texture

For a smooth, silky soup, blend it after the evaporated milk has warmed through. A hand-held blender makes it easy to control the texture.

For a rustic result, skip blending or blend only part of the pot. The tender lentils will remain visible and give the soup more bite.

Serve it while warm

Stir in the coriander at the end so its fresh flavour stays noticeable. Taste and adjust the salt and pepper before serving.

Bread, flatbread or a simple green salad all make practical accompaniments. The soup is also filling enough to serve on its own as a light meal.

Recipe notes & tips

• Rinse the lentils before adding them to the pot.
• Keep the spices moving in the pan so they do not scorch.
• Stir from the bottom of the pot as the lentils simmer.
• Remove the bay leaf before blending.
• Blend in short bursts if you want to keep some lentils whole.
• Season after adding the evaporated milk, then taste again before serving.

Variations

• More heat: Increase the cayenne slightly if you prefer a fierier soup.
• No saffron: Leave it out; the cumin, paprika and turmeric still bring plenty of warmth.
• Vegetarian bowl: Choose vegetable stock to keep the soup meat-free.
• Extra herbs: Add more chopped coriander when serving for a fresher finish.
• Rustic texture: Skip the blender and serve the tender lentils whole.

Common mistakes to avoid

• Rushing the onion: Give it 5–7 minutes to soften and brown lightly for a fuller base.
• Scorching the spices: Stir constantly during their brief cooking time and lower the heat if needed.
• Lumpy flour: Stir thoroughly as you pour in the stock so the flour dissolves.
• Leaving lentils unstirred: Scrape the bottom occasionally to stop them sticking.
• Over-blending: Blend gradually and stop when the soup reaches your preferred texture.
• Adding coriander too early: Stir it in at the end to retain its fresh flavour.

How to store

Cool leftovers and refrigerate them in a covered container for up to 3–4 days. Reheat gently in a saucepan, stirring often; add a splash of stock or water if the soup has thickened. Freeze in portions for up to 3 months, then thaw in the fridge before reheating.
