Light Mercimek Soup (Turkish Red Lentil Soup)
Why this recipe works
- Silky without cream: Red lentils break down naturally as they simmer, giving the soup a smooth, creamy body once blended.
- Warm, balanced flavour: Tomato purée, cumin and sweet paprika add depth while the onion, carrot and garlic create a rounded savoury base.
- Bright finish: Lemon juice is added at the end so the soup stays fresh and lifted rather than heavy.

Ingredient notes
- Rinse the lentils well: Rinsing red lentils until the water runs mostly clear helps the soup taste cleaner and keeps the finish lighter.
- Choose the paprika style: Sweet paprika keeps the flavour mellow and classic; smoked paprika gives the soup a deeper, smokier note.
- Add lemon gradually: Stir in the lemon juice a little at a time and taste as you go, as stock and tomato purée can vary in acidity.
Texture tips
- Blend thoroughly: For the silkiest texture, blend until no lentil or carrot pieces remain, then return the soup to a low heat briefly.
- Adjust the consistency: Red lentil soup thickens as it stands; loosen it with a splash of hot water when reheating or before serving.
Make-ahead tips
- Good for batch cooking: The soup keeps well in the fridge for several days and can be frozen in portions for easy lunches or starters.
- Reheat gently: Warm in a saucepan over a low heat, stirring often and adding a little water if it has thickened.
Authenticity notes
- Turkish home-style soup: Mercimek çorbası is commonly served smooth, warm and simple, often finished with lemon to brighten the lentils.
- Texture varies by cook: Some versions are left slightly rustic, but blending fully gives the polished, velvety texture used here.

Ingredients
Instructions
- Warm the olive oil in a saucepan over a medium heat. Finely chop the yellow onion, dice the carrot, and finely chop the garlic, then add them to the pan with a pinch of the fine sea salt. Cook for 8 to 10 minutes, stirring, until softened but not browned.
- Stir in the tomato purée, sweet paprika and ground cumin and cook for 1 minute until fragrant. Add the red lentils and vegetable stock, then bring to a gentle simmer. Cook for 18 to 22 minutes, stirring occasionally, until the lentils and carrot are very tender.
- Blend the soup until completely smooth and silky, then return it to a low heat. Season with the remaining fine sea salt and the black pepper, then simmer for 2 to 3 minutes to bring it together. If you want it lighter, add a splash of hot water from the kettle and reheat gently.
- Halve the lemon and squeeze in the juice a little at a time, tasting as you go. Ladle into bowls and finish with a small drizzle of olive oil. Serve hot.
Recipe notes
Tips
- Rinse the red lentils in a sieve-strainer until the water runs mostly clear for a cleaner, lighter finish.
- Keep the heat gentle once the lentils go in; a steady simmer helps the soup stay bright rather than tasting cooked out.
- Food safety: if serving to vulnerable groups, make sure the soup is piping hot all the way through before serving.
Substitutions
- Replace Vegetable stock with water for an even lighter soup; increase Fine sea salt slightly to taste.
- Replace Sweet paprika with Smoked paprika for a smokier finish.
Storage
- Refrigerate up to 4 days
- Cool completely, then refrigerate in a sealed container. Reheat gently in a saucepan over a low heat, stirring often and adding a splash of water if it has thickened; bring to a simmer until piping hot. Freeze in portions for up to 3 months and defrost overnight in the fridge before reheating.
