My husband orders lentil soup whenever we go out for Lebanese food. While I grew up eating a slightly different version of Lebanese lentil soup (made with spinach and brown lentils), I’ve been on a mission to recreate the restaurant version my husband adores.

The secret? A combination of creamy potatoes and red lentils. When cooked and pureed, they turn into a silky soup with the perfect texture.

For added smokiness and flavor, I like to add smoked paprika along with cumin and turmeric.

Right before serving I like to top with a dollop of plain yogurt. Not only does the tanginess balance out the slight heat and spice from the soup but it cools down the dish so you don’t burn your tongue. I find this to be especially useful when you’re 3 years old and don’t have much patience at dinner time.

  1. I love this recipe. I always use just six cups of water or broth to make it a bit thicker. That’s my only tweak. Thanks for such a simple and yummy crock pot meal.

  2. I love this recipe and have made it multiple times. Simple but delicious. I have had a lot of lentil soups but this one has an extra zing and I like that it is more brothy rather than thick and stew like. Great paired with crunchy bread and a fresh salad.

  3. Wow, I was definitely disappointed. I’m sorry to the author but the only Lebanese lentil soup I’ve ever had was from a restaurant. I wanted to copy it and thought this recipe was most appealing. After all steps taken it felt like something was missing. It had two sides of the taste bud but missed the connecting spice. I wanted to love this soup. After researching many other recipes I chose to add dried mint. It definitely made it more acceptable. I enjoyed it enough to eat my giant pot of soup, but: to me this soup is still lacking. Try it with mint. Let me know. I’m dying for more creative options!

    1. It is strange that such a simple receipe would take such a long time to get ready! My yellow lentils soups are ready within 15 to 20 minutes! Why does yours needs such a long cooking time?

  4. My sister made this in her Instapot, and then used an immersion blender to make it nice and creamy. It was delicious! I can’t wait to make it myself!

  5. Always love making this recipe in the crockpot!! Recently I purchased an Instapot. Do you have any recommendations for cook time in the Instapot?
