Ingredients

  • 2 tbsp (30 ml) olive oil (or unsalted butter, or half of each for classic flavor)
  • 1 medium (about 150 g), diced yellow onion (white onion also works)
  • 1 large (about 120 g), diced carrot (peeled)
  • 3 cloves, minced garlic (fresh for best flavor)
  • 1.5 tbsp (25 g) tomato paste (adds color and tang)
  • 1.5 tsp ground cumin (key Turkish flavor)
  • 1 tsp sweet paprika (or half sweet, half smoked)
  • 0.5 tsp ground turmeric (optional, adds color and warmth)
  • 1 cup (190 g), dried red lentils (Turkish style uses split red lentils)
  • 1 small (about 120 g), peeled and diced potato (optional, for extra creaminess)
  • 4 cups (960 ml) low-sodium vegetable broth (or chicken broth for non-vegan)
  • 1 cup (240 ml) water (add more as needed to thin)
  • 1.25 tsp, or to taste salt (adjust depending on broth)
  • 0.5 tsp, freshly ground black pepper (to taste)
  • 1 large, cut into wedges lemon (for serving, essential for brightness)
  • 1 tsp, crumbled dried mint (optional but traditional garnish)
  • 0.5 tsp, or to taste red pepper flakes (pul biber) (optional spicy butter drizzle)
  • 1.5 tbsp (20 g) unsalted butter or olive oil (for drizzle) (optional, for finishing the soup)

Instructions

  1. Rinse the red lentils in a fine-mesh sieve under cool running water until the water runs mostly clear. Drain well and set aside. This helps remove excess starch and any dust so the soup cooks evenly and stays light.
  2. Prep the aromatics: finely dice the onion, dice the carrot and potato into small, even pieces (about 1 cm), and mince the garlic. Smaller pieces cook faster and blend into the soup more easily.
  3. In a large heavy-bottomed pot or Dutch oven, heat the olive oil over medium heat. Add the diced onion and carrot with a pinch of salt. Sauté for 5–6 minutes, stirring often, until the onion is soft and translucent and the carrots start to soften.
  4. Stir in the minced garlic and cook for 30–60 seconds until fragrant, being careful not to brown it. Add the tomato paste, cumin, paprika, and turmeric. Cook the tomato paste and spices for 1–2 minutes, stirring constantly, until the paste darkens slightly and smells sweet and roasted. This step builds deep flavor.
  5. Add the rinsed red lentils and diced potato to the pot. Stir to coat the lentils and vegetables in the tomato-spice mixture so everything is evenly distributed.
  6. Pour in the vegetable broth and water. Stir well, scraping up any browned bits from the bottom of the pot. Bring the mixture to a gentle boil over medium-high heat.
  7. Once boiling, reduce the heat to low, cover the pot partially with a lid, and simmer gently for 20–25 minutes. Stir every 5–7 minutes to prevent sticking. The soup is done when the lentils have broken down, the potato is very tender, and the soup looks thick and creamy.
  8. Season with salt and black pepper. Taste and adjust seasoning, adding more salt or spices as needed. If the soup is thicker than you like, stir in a splash of hot water or broth to loosen to your preferred consistency.
  9. For a traditional smooth mercimek texture, use an immersion blender directly in the pot to blend the soup until silky. For a bit of rustic texture, pulse just a few times or blend only half the soup. You can also carefully transfer portions to a blender, vent the lid, and blend until smooth, then return to the pot.
  10. If making the optional spicy butter drizzle, heat the butter or olive oil in a small pan over low heat. Add the dried mint and red pepper flakes (pul biber) and warm for 30–60 seconds until fragrant but not browned. Remove from heat immediately so the spices do not burn.
  11. Ladle the hot Turkish lentil soup into bowls. Spoon a little of the mint-chili butter or oil over each bowl, if using. Serve right away with lemon wedges on the side. Encourage everyone to squeeze plenty of lemon juice into their soup just before eating—this brightens all the flavors.
  12. Garnish with extra dried mint, fresh parsley, or a pinch of paprika if you like. Enjoy with warm crusty bread, pita, or a simple green salad for a complete, cozy meal.

Pro Tips & Variations

  • Rinse and simmer gently – Washing the lentils and keeping the simmer low prevents foam and helps the soup turn creamy without sticking.
  • Adjust the thickness – For a café-style mercimek, blend until smooth and add hot water as needed; for a rustic bowl, leave some lentils whole.
  • Make it seasonally cozy – In colder months, add a pinch of cinnamon or extra smoked paprika; in warmer weather, finish with lots of lemon and fresh herbs for a lighter vibe.
  • Easy variations – Swap part of the carrot for sweet potato, use chicken broth for extra richness, or make it fully vegan with oil instead of butter and vegetable broth.

Storage & Serving

Let the Turkish lentil soup cool to room temperature, then transfer to airtight containers. Refrigerate for up to 4 days; the soup will thicken as it sits, so thin with a splash of water or broth when reheating on the stove over low heat or in the microwave. For longer storage, freeze in portioned containers for up to 3 months, leaving a little space at the top for expansion. Thaw overnight in the fridge, then reheat gently, adding extra liquid as needed. Serve hot with lemon wedges, a drizzle of chili-mint butter or olive oil, and warm bread or a simple salad on the side.

Frequently Asked Questions

Can I use green or brown lentils instead of red?

You can, but the flavor and texture will be different. Red lentils break down and become creamy, which is traditional for Turkish mercimek soup. Green or brown lentils hold their shape more and take longer to cook, so the soup will be chunkier and may need extra cooking time and liquid.

Is Turkish lentil soup mercimek vegan?

It can be. Use olive oil instead of butter and choose vegetable broth. The base recipe is naturally dairy-free and plant-based, so swapping the fat and broth is all you need to make it fully vegan.

How can I make this soup spicier?

Increase the red pepper flakes or add a pinch of cayenne to the pot. You can also make extra spicy butter or chili oil to drizzle over each bowl so everyone can adjust the heat level to their taste.

Can I make this soup ahead for meal prep?

Yes. Turkish lentil soup reheats very well and even tastes better the next day as the flavors meld. Store in the fridge for up to 4 days or freeze for up to 3 months. When reheating, add a splash of water or broth to bring it back to a creamy, pourable consistency.

What should I serve with Turkish lentil soup mercimek?

Serve it with lemon wedges, crusty bread or pita, and a simple salad like cucumber-tomato with olive oil and lemon. It also pairs well with grilled vegetables or roasted chicken for a heartier dinner.
