    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 really really love lentil soup, but every time I’ve made it I’ve not been able to get it as silky as my favorite restaurant. Then I found this recipe and you speak right to the silkiness coming from other vegetables! Genius! Thank you so much, looking forward to making this and will report back after I do.

    2. Made this soup last week!!! doubled the recipe because my husband loves soup! It was delicious and soooooo easy!! Love throwing everything in and walking away.

    3. Hi Liz, the soup is already thickening and is absolutely yummy. Re the stars. I tried to make it 5 stars before and the computer got ahead of me and wouldn’t let me do it.

    4. I just took this soup out after being in my slow cooker on high for four hours. I pureed it with my immersible blender, but it is very thin, not at all creamy. I used the tiny potatoes…halved six of them. Help! I want to try again. Patti

            1. HI Liz, I realized my mistake last night. I put 2 boxes of veggie broth in the soup, which added 2 extra cups. I have it all in the fridge and will put it all in a. Pan today and hope most of the extra liquid will evaporate. Glad I figured this out and know this soup Will be a regular from now on. Thank you! Patti

              1. Ahhh ok that makes sense!! So glad you figured it out -we love this recipe and make it all the time so I was a bit baffled!! Another way to fix it would be to add more lentils. :) Can you please revise the stars from three to five since it turns out you didn’t follow the recipe correctly? Thank and enjoy!!

        1. I am excited to make this, but I couldn’t find red lentils at my grocery store. Can I use the brown lentils in my pantry or is the taste different enough that it’s worth looking elsewhere for red lentils? Btw, I love so many of your recipes!

          1. This makes a very large 2 cup serving so the count is accurate. A few easy ways to reduce the sodium: buy chicken stock without any sodium, don’t add the salt, cut the serving in half to one cup. Hope that helps!

        2. Liz, this is just gorgeous. I love a good soup recipe. This one is perfection. I’m with you on adding yogurt to help cool it down. Plus it tastes amazing mixed in. That photo of you in the pink top holding the bowl is stellar. Such a great shot.

        3. Hi Liz, I’m just starting to experiment with lentils. For this recipe do you have to soak the lentils first? Or just wash them and add them to the crockpot?
          Thank you!

            1. Can I use regular red potatoes? Maybe cut up? I am just trying to use what I have on hand but worried after 8 hours slow cooking that the RED potatoes wont blend nicely. I don’t want to waste food or 8 hours:) Please let me know your thoughts on red potatoes for this recipe. I am excited to make it!

              I love ALL your soups with lemon!!

                1. Red potatoes worked fine (ish) I would definitely peel them! The peels didn’t blend well. I used a hand held blender thing. So, red potatoes ok. It turned out great! I froze at least six jars!! Thank you!

          1. In you instructions for this lentil soup, I think your reversed your times for the slow cooker: 4 hours at Low or 8 hrs at High. Probably should be the other way around?
