This red lentil soup is simple, nourishing, and packed with flavor. Made with red lentils and a handful of vegetables, it’s blended until silky smooth, then finished with a warm, spiced butter drizzle.
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
- 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: 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: 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: 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: 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.
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
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!
I’ve made this amazing recipe and we all loved it!
It’s delicious, filling and nutritious!
Happy to hear this red lentil soup was a hit, Yas!
Made this today. No changes. Delicious soup you have to make. I blended it till smooth, yum
Thrilled to hear you loved this lentil soup, Cindy!
I love starting my new year with a light yet nourishing soup, and this lentil soup hits the mark! I added 1/2 cup more lentils and a bit more broth, so we get to stretch the meal. The aleppo drizzle really jazzes the soup. So good!
This is a great soup recipe to kick off the new year! I’m happy you loved it, Reese!
Yes I made this and it turned out great! I squeezed fresh lemon juice in the soup and added sour cream on top and the flavors popped! Definitely making it again
Wonderful! So happy you loved it, Alison!
So delicious! The lemon juice and Aleppo pepper butter were perfect toppings too!
Glad you’re loving this lentil soup, Sue!
This is an absolutely AMAZING recipe! I made it tonight and it was sooooo good.
I had to make a couple of substitutions because of what I had on hand, and it still turned out super delicious. Chicken stock instead of veggie, gochugaru (a mild Korean red chili flake) instead of Aleppo pepper. But otherwise I followed the recipe exactly. It’s perfection, the whole family loved it – thank you!
Glad this lentil soup still turned out great with what you had on hand, Michelle!
This soup is so easy to make. The lemon juice and aleppo butter take it up to the next level. The soup does turn out fairly thin (might have been the size of my potato). I might use 5 or 5.5 cups of broth/water next time because I tend to prefer a bit thicker soup. Will definitely make it again.
I’m so glad you loved this red lentil soup, Veronica!
yum! starting the first week back at work strong. prepped for lunches. definitely don’t skip the lemon and pepper butter!
What a great way to start the week! Enjoy, Jillian :)
Simple, healthy, and delicious!
Glad you loved this lentil soup, Alanna!
Just made this soup and it was excellent! Next time I’ll double the recipe. 😁
Thrilled to hear you loved this recipe, Ann!
Another winner. Perfect with a crusty piece of sourdough bread and butter. I loved the addition of lemon and Aleppo butter. Thanks, Lisa!
I’m so glad you loved this lentil soup, Alan!
Soothing, comforting, nutritious, fairly simple to make & yummy!
Made this soup tonight – used 2 garlics instead of 3, just personal preference & added 2 stalks peeled & diced celery (Yes, I like to peel the threads off the back of each stalk).
Will make again!
Thrilled to hear you loved this lentil soup, Marcy!
This is so simple yet so perfect. I used green lentils (because I had them on hand) and it worked perfect. I decided to blend half of the soup so I could still have some chunkiness. It was so satisfying. Definitely going to be a staple recipe for me now!
Glad this worked out great with green lentils instead, Leah!
Hi Lisa
Just made and had this soup for lunch, so delicious, the touch of butter and Aleppo pepper on top, great added touch!!!
Happy to hear you loved this lentil soup, Shirleen!
I love all your recipes and this one did not disappoint! I made it last night and it was absolutely delicious. It had just the right amount of spice and heat for a cold New England night. Since I couldn’t find alleppo flakes at my grocers I subbed in paprika and cayenne, and the butter added a sweet and spicy note to the dish. I wouldn’t leave that out! So yummy!
Thrilled to hear you loved this lentil soup, JP!
I always used to make Lentil soup on New Year day – just didn’t have time this year – so thanks for posting the recipe. The only thing different I do from this recipe is I soak the lentils over night – to help lessen any gas from the lentils; and I add any left over ham I have from Christmas – just to add more protein and use of the ham. Again, thanks for the posting this recipe.
Glad this came as a good reminder to make lentil soup for New Years, Kathi!
This is incredibly delicious and super simple to make — it’s even good if you’re lazy and don’t feel like whipping out the immersion blender, and leave the potato and carrot whole. 10/10 would make again.
Wonderful! I’m so glad you loved this lentil soup, Alegra!
Going to make this soup.
I make in a crock pot Red Lentil, Chickpeas, and dice tomatoes.
It is a great hit with my friends
Excited for you to try this lentil soup, Maureen!
