Turkish Lentil Soup Ingredients and Easy Recipe

Turkish lentil soup, often called mercimek çorbası, is a comforting Turkish soup made with red lentils, vegetables, and warm spices, then blended until smooth. It is commonly served hot with lemon, and this straightforward stovetop version balances the lentils’ earthy flavor with tomato paste, cumin, and dried mint.

Ingredients

1½ cups (285 g) dried red lentils, picked over and rinsed
1 medium yellow onion (about 150 g), finely chopped
1 medium carrot (about 100 g), peeled and diced
1 small potato (about 150 g), peeled and diced
2 tablespoons (30 ml) olive oil
1 tablespoon (14 g) unsalted butter
1 tablespoon (16 g) tomato paste
1 teaspoon (2 g) ground cumin
1 teaspoon (2 g) sweet paprika
½ teaspoon (about 0.5 g) dried mint
6 cups (1.42 L) low-sodium vegetable or chicken broth
1 cup (240 ml) water
1 teaspoon (6 g) fine salt, plus more to taste
¼ teaspoon (0.5 g) black pepper
2 tablespoons (30 ml) lemon juice, plus lemon wedges for serving
Optional garnish: 2 tablespoons (28 g) butter, ½ teaspoon (1 g) paprika, and 1 teaspoon (1 g) dried mint

Instructions

Put the lentils in a fine-mesh strainer and rinse under cool running water, stirring them with your hand, until the water runs mostly clear. Check for small stones or debris as you rinse. Chop the onion, carrot, and potato into small, fairly even pieces so they soften at a similar rate.
Set a large, heavy-bottomed pot over medium heat. Add the olive oil and 1 tablespoon of butter. When the butter has melted, add the onion, carrot, and potato. Cook for 7 minutes, stirring every minute or two, until the onion is translucent and the vegetables begin to soften. Keep the heat moderate; browning the onion deeply can make the finished soup taste sweeter and darker than intended.
Stir in the tomato paste, cumin, paprika, and dried mint. Cook for 1 minute, stirring constantly, to loosen the paste and let the spices become fragrant without scorching. If the mixture sticks to the bottom, lower the heat and add a small splash of broth.
Add the rinsed lentils, broth, water, salt, and black pepper. Stir well and scrape the bottom of the pot to release any flavorful bits. Bring the mixture just to a boil, then reduce the heat to maintain a gentle simmer. Partially cover the pot, leaving a small gap for steam to escape, and simmer for 24 minutes, stirring a few times so the lentils do not settle and stick.
Check that the lentils and diced vegetables are very soft. Take the pot off the heat and blend the soup until smooth with an immersion blender, keeping the blender head submerged to avoid splashes. If using a countertop blender, let the soup cool briefly, work in small batches, and follow the blender’s directions for hot liquids; do not seal hot soup in a full blender jar.
Return the blended soup to low heat. Stir in the lemon juice and simmer for 2 minutes, stirring occasionally. Taste and adjust the salt, pepper, or lemon. The soup should be smooth but pourable; stir in a little hot water or broth if it is thicker than you like.
For the optional spiced butter, melt 2 tablespoons of butter in a small pan over low heat. Stir in ½ teaspoon paprika and 1 teaspoon dried mint for about 20 seconds, just until fragrant. Ladle the soup into bowls and drizzle the butter over the top, or pass it at the table with lemon wedges.

Tips

Rinse, but do not soak. Red lentils cook quickly and do not need an overnight soak. Rinsing removes surface starch and any dust, while checking them first helps catch debris. The lentils will soften and break down during the simmer, which is what gives this soup its naturally creamy body.
Keep the simmer gentle. A hard boil can make lentils foam up and stick to the pot, while a low simmer cooks them evenly. Stir especially around the bottom and corners. If the soup thickens before the vegetables are tender, add hot water a little at a time rather than turning the heat up.
Adjust thickness after blending. Lentils continue absorbing liquid as the soup sits, so the first bowl may be looser than leftovers the next day. Add hot broth or water gradually when reheating. If it is too thin, simmer it uncovered for a few minutes, stirring often.
Choose broth with its salt level in mind. Low-sodium broth makes it easier to season the finished soup, but regular broth works too; start with less added salt and taste at the end. Vegetable broth keeps the recipe vegetarian, while chicken broth gives it a fuller savory flavor. For a dairy-free version, use oil instead of butter, including for the optional garnish.

Serving Suggestions

Serve the soup hot in shallow bowls with lemon wedges so each person can add acidity to taste. A squeeze of lemon brightens the soft lentils and warm spices, and the optional paprika-mint butter adds a fragrant, rich finish. Flatbread or crusty bread makes a useful companion for catching the last spoonfuls. A simple chopped salad with cucumber, tomato, and parsley can provide a fresh contrast without making the meal feel heavy.

For a more substantial meal, serve the soup alongside rice, bulgur, or a small plate of roasted vegetables. Keep toppings separate if several people are eating: lemon, the spiced butter, and extra dried mint let diners adjust their own bowls. If serving the soup as a starter, use smaller portions and make the main course something simply seasoned, since the soup already has plenty of savory flavor.

Variations

There are many household and regional versions of Turkish lentil soup, so the proportions of vegetables, spices, and finishing butter can vary. This version uses carrot and potato for body, but either can be omitted; replace the removed vegetable with an equal amount of broth if you want to keep the soup’s original volume. A little extra carrot makes the result sweeter, while more potato makes it thicker and milder.

For a deeper tomato flavor, use 2 tablespoons (32 g) of tomato paste instead of 1 tablespoon and reduce the added salt only if your broth is salty. Aleppo pepper or pul biber can replace some or all of the sweet paprika in the garnish; it contributes a gentle fruity heat, so add it sparingly if you prefer a mild bowl. If pul biber is unavailable, a pinch of red pepper flakes is a practical substitute, though it is sharper and less fruity.

For a dairy-free soup, use olive oil in place of the butter and finish with a drizzle of good olive oil rather than spiced butter. To make the soup more rustic, blend only part of it, or skip blending and mash some lentils against the side of the pot. The texture will be less silky but still satisfying. Green or brown lentils are not a direct substitute: they hold their shape and take longer to soften, so the soup will be less smooth and will need a different cooking time.

Storage and Reheating

Cool the soup and refrigerate it within 2 hours of cooking in shallow, airtight containers. It keeps for 3 to 4 days in the refrigerator. Store any lemon wedges and spiced butter separately when possible; fresh lemon added at serving tastes brighter, and the butter topping is easier to portion separately. The soup thickens as it chills, which is normal rather than a sign that it has gone wrong.

Reheat only the portion you need on the stovetop over medium-low heat, stirring often and adding broth or water until it reaches the consistency you want. For food safety, USDA FSIS guidance is to reheat leftovers to 165°F (74°C); check the center with a food thermometer. You can also reheat a serving in the microwave in a covered, microwave-safe bowl, stirring partway through and checking the temperature in more than one spot. Freeze cooled soup in airtight freezer containers for up to 3 months for best quality. Leave a little room for expansion, thaw it overnight in the refrigerator, and reheat it thoroughly; the texture may need a splash of liquid and a good stir after thawing.

Frequently Asked Questions

Can I use yellow lentils instead of red lentils?

Yellow split lentils can work if they are the same quick-cooking type, but their color and flavor may be slightly different. Check the package directions because varieties differ in how quickly they soften. Whole green or brown lentils are not ideal for this smooth soup: they usually take longer to cook and tend to keep their shape, so the result will be more textured.

Do I have to blend Turkish lentil soup?

No. Blending is common for a smooth, cohesive bowl, but it is optional. For a rustic texture, use a potato masher to crush some of the softened lentils and vegetables, or blend only half the pot. If you prefer a completely smooth finish, an immersion blender is convenient; use care because hot soup can splatter.

Why is my soup too thick?

Red lentils absorb liquid as they cook and continue to thicken after blending and chilling. Stir in hot water or broth a few tablespoons at a time until the soup pours easily from a ladle. Taste it again after thinning, since the added liquid may mean it needs a little more salt, lemon, or pepper.

Can I make it ahead?

Yes. The soup can be cooked, cooled, and refrigerated for 3 to 4 days, and its flavors settle nicely by the next day. Keep the lemon juice and garnish separate if you want the freshest finish, then add lemon after reheating. It will be thicker when cold, so loosen it with broth or water as it warms.

What can I use if I do not have dried mint?

You can leave it out and still make a good soup. A small amount of dried oregano is a practical stand-in, although it gives the soup a more herbal, less traditional flavor. Fresh mint is stronger and wetter, so use a small amount finely chopped as a finishing garnish rather than replacing dried mint spoon for spoon.
