Why You’ll Love This Red Lentil Soup

I’ve really been craving meals like this red lentil soup lately. The kind that feels comforting and wholesome, hearty without being heavy, full of plant-based protein and fiber, and incredibly cozy for cooler days! Unlike my Mediterranean lentil soup that’s chunky and brothy, this version is blended and ultra-smooth. It’s inspired by the Turkish red lentil soup, Mercimek Çorbası, which I can’t wait to enjoy on my upcoming trip to Turkey! This soup is drizzled with the same Aleppo pepper sauce as my Turkish eggs, and its one of my favorite parts about this recipe. You’ll also love that this red lentil soup is:

  • Incredibly easy. Aside from the quick Aleppo pepper butter, everything comes together in one pot in about 30 minutes!
  • Budget-friendly. This is a fridge and pantry staple kind of soup that’s big on flavor without being expensive.
  • A great vegetarian meal. Between the veggies and protein-packed lentils, it’s hearty, satisfying, and perfect for a vegetarian soup recipe.

Red Lentil Soup Ingredients

Red lentil soup ingredients.
  • Vegetables: A simple blend of onion, carrots, and a Yukon Gold potato forms the cozy, hearty base of the soup.
  • Tomato paste and garlic: Just a little of each adds depth and richness.
  • Seasoning: You’ll need paprika, ground cumin, salt, and black pepper.
  • Red lentils: I’ll show you how to cook lentils perfectly! But the good news is that you’ll be blending them, so no need to worry if they get slightly mushy.
  • Vegetable Broth: I’ve linked my favorite brand in the recipe card.
  • Lemon: Fresh lemon adds brightness at the end—a must in my opinion!
  • Aleppo pepper sauce: The best mix of butter (or olive oil) and Aleppo pepper. I linked the one I’m using in the recipe card!

How To Make Red Lentil Soup

Step one of red lentil soup: cook the vegetables.

Step one: Start by heating the oil in a large pot over medium heat. Add the onion and carrot and let them cook for about 4 to 5 minutes, until they’ve softened. Then, toss in the diced potato and let that cook for another couple of minutes. This combo builds the perfect veggie base.

Step two of red lentil soup: Add the flavorings.

Step two: Add the garlic, tomato paste, paprika, cumin, salt, and pepper. Give everything a good stir and let it cook for about 30 seconds. You’re just waking up the spices here, so don’t walk away.

Step three of red lentil soup: add broth and lentils.

Step three: Pour in the lentils and broth, bring everything to a boil, then reduce the heat to low. Cover and let it simmer for 20 to 25 minutes, until the lentils and potatoes are very soft and basically falling apart.

Step four of red lentil soup: blend the soup.

Step four: Use an immersion blender and blend the soup until silky smooth. Turkish-style lentil soup is usually blended completely, but feel free to leave a little texture if that’s more your thing.

Step five of red lentil soup: make the butter sauce.

Make the Aleppo pepper butter. While the soup finishes, melt the butter in a small pan over low heat. Add the Aleppo pepper and stir for about 20 to 30 seconds, just until fragrant. It should smell warm and buttery, not burnt, so keep the heat low. Then, ladle the soup into bowls, drizzle with the Aleppo pepper butter, and serve with lemon wedges on the side.

Storage Tips

Let the soup cool completely, then transfer it to an airtight container and store it in the fridge for 4 to 5 days. When reheating, warm it gently on the stove or in the microwave. I also love freezing it in individual portions so I can thaw just what I need. It will stay good for up to 3 months in the freezer!

Lisa’s Tips

  • Storage tip: Let the soup cool completely, then transfer it to an airtight container and store it in the fridge for up to 4 days. I also love freezing it in individual portions. It will stay fresh for up to 3 months in the freezer.
  • You can use a Russet or Yukon gold potato here. A Russet potato is more starchy so will thicken the soup a bit more, while a Yukon gold potato is a bit creamier for a smoother finish. The choice is yours!
  • For the onion, you can use yellow or white onions. Just don’t use red onions as they can sorta muddy the color a bit. 
  • Don’t forget that you can use the Aleppo pepper for these Turkish eggs! A great, flavorful breakfast or brunch idea.

Behind The Scenes

Lisa holding a bowl of red lentil soup.

While some recipes out there use paprika on top for the spiced butter drizzle or Aleppo pepper in the soup in addition to on top (to avoid using two different spices), I had some Turkish friends tell me that both spices are necessary. They said the best red lentil soup always uses paprika in the soup and Aleppo pepper on top of the soup. So, that’s what I did in my recipe!
