Turkish Restaurant-Style Lentil Soup: Smooth, Warming and Easy to Make at Home

A bowl of lentil soup at a Turkish restaurant has a particular texture: smooth and easy to spoon, with just enough body. Add a squeeze of lemon to the buttery paprika topping, and some warm bread may be all you need alongside it.

Getting that texture at home comes down to a few simple steps. Give the onion time to soften, cook out the raw taste of the flour, and let the lentils become completely tender. I keep the tomato paste to a minimum in this recipe so the lentils remain the main flavour, with a little sweetness from the carrot.

Preparation time: 10 minutes
Cooking time: Approximately 30–35 minutes
Serves: 6–8

Ingredients

The lentil measurement below uses a 200 ml measuring cup.

• 2 × 200 ml cups dried red lentils, approximately 320 g
• 1 medium onion
• 1 medium carrot
• 2 tablespoons plain flour
• 5 tablespoons neutral cooking oil
• ½ tablespoon tomato paste or Turkish red pepper paste, optional
• 2 litres hot water
• 1 teaspoon salt, adjusted to taste
• ½ teaspoon ground black pepper
• 1 teaspoon ground cumin, optional

For the topping

• 2 tablespoons butter
• 1 teaspoon paprika, preferably sweet and unsmoked

To serve

• Lemon wedges
• Toasted bread, optional

How to Make Turkish Lentil Soup

1. Rinse the lentils and prepare the vegetables

Place the lentils in a fine-mesh sieve and rinse thoroughly under running water. Leave them to drain while you finely chop the onion and dice the carrot.

The soup will be blended later, so the vegetables do not need to look perfect. Small pieces of carrot will simply cook more quickly.

2. Build the flavour

Heat the oil in a large saucepan over medium heat. Add the onion and cook, stirring occasionally, until softened and lightly golden. Avoid letting it turn dark brown, as this will affect the colour and flavour of the soup.

Stir in the flour, lower the heat slightly, and cook for 1–2 minutes, stirring constantly. You want to cook out its raw smell without browning it.

If using tomato or red pepper paste, stir it in and cook briefly.

3. Simmer until tender

Add the carrot and drained lentils. Stir a few times, then gradually pour in the hot water, stirring as you go to prevent the flour from forming lumps.

Bring to the boil, then reduce the heat and leave the lid slightly ajar. Simmer gently for about 25–30 minutes, until the lentils have broken down and the carrot is soft enough to crush easily.

Stir occasionally, reaching across the bottom of the pan to stop the soup from catching.

4. Blend until smooth

Take the pan off the heat. Carefully blend with an immersion blender, keeping the blade submerged to avoid splashes. If you do not have a blender, press the soup through a fine sieve using the back of a spoon.

Add the salt, black pepper and cumin, if using. If the soup is thicker than you like, stir in a little hot water.

Return to low heat and simmer for another 5 minutes. Taste and adjust the salt, especially if you have added extra water.

5. Make the paprika butter

Melt the butter in a small pan. Once it begins to foam gently, remove it from the heat and stir in the paprika.

The remaining heat will release the paprika’s colour and aroma. Be careful here: paprika burns quickly and can become bitter.

Ladle the soup into bowls and drizzle the paprika butter over each serving. Put lemon wedges on the table so everyone can add as much as they like.

A Few Tips from My Kitchen

Adjust the consistency after blending. It is easier to judge the texture once the lentils and vegetables are smooth. Add hot water a little at a time, stirring between additions.

Use stock for a fuller flavour. Replace 200–400 ml of the water with chicken or beef stock, keeping the total liquid at 2 litres to begin with. If your stock is salted, season the soup at the end.

Leave out the paste for a lighter colour. Without tomato or pepper paste, the colour of the lentils and carrot comes through more clearly. If you prefer to include it, start with the small amount listed.

A small potato can replace the flour. Peel and dice it, then add it with the carrot. It will give the soup body as it cooks. Adjust the consistency after blending.

Expect the soup to thicken as it stands. When reheating, stir in a little hot water until it reaches the consistency you enjoy.

What to Serve with Lentil Soup

For a simple lunch, serve it with toasted bread and lemon. As a starter for dinner, it works well before roast chicken, a vegetable dish or bulgur pilaf.

I like to spoon the paprika butter over the individual bowls just before serving. Its aroma reaches the table while it is still warm, and you get a little of that buttery flavour with the first spoonful.

Enjoy!
