This is a lentil soup that defies expectations of what lentil soup can be. Based on a Turkish lentil soup, mercimek corbasi, it is light, spicy and a bold red color (no murky brown here): a revelatory dish that takes less than an hour to make. The cooking is painless. Sauté onion and garlic in oil, then stir in tomato paste, cumin and chile powder and cook a few minutes more to intensify flavor. Add broth, water, red lentils (which cook faster than their green or black counterparts) and diced carrot, and simmer for 30 minutes. Purée half the mixture and return it to the pot for a soup that strikes the balance between chunky and pleasingly smooth. A hit of lemon juice adds an up note that offsets the deep cumin and chile flavors.

Cooking Notes

This is daal, minus a few essential seasonings.

Best made by sautéing the onions, then adding ginger and garlic paste to taste; sautéing fresh chopped tomatoes (no paste); adding spices (turmeric, coriander powder, chili powder, a touch of cinnamon if you like) once the oil has taken on the red color from the tomatoes and the vegetables have a glazed appearance.

Not enough salt in this recipe.

Make a simple chutney with yogurt, green chilies and cilantro.

Was looking forward to this making this, and after seeing the comments, made a few changes...used chicken stock, and, instead of water, one 14oz. can of diced tomatoes and more stock. I used 3 carrots instead of 1, and didn't bother to blend....and added a bag of spinach, finished with grated parm, and it was fabulous.

This is a very tasty recipe but I have two suggestions:
1. There is too much liquid for the amount of lentils; therefore add one or two small potatoes, diced, to give the soup more body.
2. Step 4 - No need for more mess of moving half the soup into another pot; get the same rougher consistency by pureeing in one pot but in short bursts until somewhat, but not entirely smooth.

This recipe makes 4 small bowls of soup. Double the recipe to serve 4-6

Absolutely delicious! I will never buy lentil soup again. This soup is better than any I've had at any Persian, Arabic or other mediterranian restaurant.
I did add an extra 2 cloves of garlic, extra 1/4 c of lentils, an extra carrot, and used 1/4 tsp chili powder, 1/4 tsp cayenne, and 1/4 tsp of kebab spices ( mostly coriander and cumin)
Consistency and flavor were perfect!

I followed the suggestion to use 2 carrots, 3 garlic cloves, and 5 cups of chicken broth, 1.5 cup red lentil and no water. I grated my carrots and sauteed it with the garlic and onion. I normally don't like red lentils, but this was fantastic. The lemon really rounded the soup. Will make this again.

Jules: for this quantity (1 cup lentils), a couple of plum tomatoes should do. Important to get nice juicy ripe tomatoes, and to sauté all the vegetables until the oil rises to the top and takes on the red tomato color, otherwise it will retain a somewhat raw taste no matter how long you simmer the soup. That first step ensures the full release of flavor of the spices.

I ate this soup almost every day in Turkey, where sumac and/or mint are added at the end. Sumac is not hard to find in the US (Whole Foods carries it), and adds a lovely tartness more mellow than lemon. The mint is also a nice touch.

You'll get more color out of the carrot and the tomato paste than the lentils. Red lentils fade rapidly to pale pink and then yellow as they are exposed to prolonged heat. But forget their color, it's the flavor and texture that makes them so desirable. If you want more red bump up the tomato or add some sweet smoked Spanish paprika--the subtle smoke note is terrific with lentils of all hues.

We like to zest the lemon as well. The brightness of flavor this adds is incredible. The flavor just explodes in your mouth!

I make this all the time. At the end I often add fish (a pound of tilapia works nicely) to make a rich one-pot dinner - like a thick chowder. (The fish cooks in the hot soup.) I like things spicy so I then adjust the seasonings (including the amount of lemon) accordingly; and I let the volume reduce a bit by not covering the pot tightly when simmering.

Just made this for the first time, and it was delicious. I understand that some people do not like cilantro, but it really does benefit from that flavour, as well as the lemon juice. Keep those two ingredients in there, and you won't be sorry! I followed the recipe exactly, and didn't find it too thin. I have leftovers, and keep going back to the pot for another spoonful. I will say that it gets thicker as it cools. Highly recommend, and will definitely make again.

After I used the immersion blender, I added a bunch of lacinato kale torn into small pieces and cooked for a few more minutes until wilted. Delicious!

I have made this soup at least 3 dozen times, always yielding the same delicious results. It freezes beautifully making it a great option for make-ahead menu item or impromtu dinner party. In addition to the cilantro, I like to garnish with toasted pepitas. It's so good I've served it as light lunch item on Thanksgiving.

This is such an easy, healthy, inexpensive soup. I add two tablespoons of barley to give it a little silkiness. Also use ground chipotle pepper. I cook this in my pressure cooker for about 9 minutes, which results in no need for the immersion blender step.

Put this on your rotation. Don’t get crazy with your cilantro.

Add to rotation!!

Zatar really put this over the top. Great vegan dish although I did use chicken stock. Greek yogurt might be a nice addition. I also added more salt and pepper.

Add more carrots, add diced tomatoes, sumac and less water

This soup never leaves my NYT Cooking “recently viewed” queue. It is just the best quick weeknight meal. Thank you Melissa.

Perfect. All the people on here are trying to make another recipe. Some of the comments are just silly with all the additions and changes. Just trust the recipe. Its great. Just a simple lentil soup that needs nothing more. The lemon and cilantro make it. We had it with some broiled halibut trimmings (the trimmings are only $7 per lb) that I tossed in some curry powder. And a little yogurt with olive oil and cilantro on the side. Simple Monday night. Extremely pleased.

Omitted the lemon and cilantro, but I added coriander.

Delicious soup! Used all of the liquid, about 1/4 c lentils, added a 1/4 t each of chipotle powder and smoked paprika. Did not blend as the texture was great. Used a full lime instead of lemon. (Lime is so tasty with cilantro) Will make many more times.

1/4-1/2 chipotle chili powder, 1.5 cup lentil

I followed the recipe but I found this was a pale, off-flavoured dish. It tasted like.... tomato paste? and carrot paste?

Delicious! I added sumac and a dollop of yogurt at the end. I used twice as much tomato paste, carrot and garlic and 1.5 cups of lentils, it worked out great.

I love this soup so much and have made it dozens of times. It’s one of the few dishes that I actively crave. Lately I have been adding red pepper flake, smoked paprika, two chipotle peppers, and a teaspoon of adobe sauce to enhance the spice and smokiness. I also use vegetarian “Not Chick’n” bouillon cubes because we don’t eat meat.

We use this recipe in my food tech classes when the kids learn knife skills. We end up with a whole bunch of diced onion, celery and carrot and this soup is a great way to use it up. There's no celery on the listed ingredients but why waste it? Adds flavour. We also double the garlic, and the kids blend it to death ("ew vegetables"). Then after all the complaints they actually try it and love it. I also make it at home for easy dinners. The lemon is key. Takes it from nice to incredible.

I love this soup, and it's great to riff on. I've used any kind of tomato, various liquid including all veggie stock for a vegetarian friend. I've thrown in leftover couscous or shredded chicken, greens or frozen peas at the end, a dollop of yogurt or sour cream.... I never bother to blend it, and it's always scrumptious.

Really good as written but I’ve landed on the following adjustments after several iterations: 1. Triple the garlic 2. 3-4 carrots add a bit more body and touch of sweetness 2. Replace tomato paste with harissa paste such as Trader Joe’s (add more like 2 TBSP if you like a little kick) 3. 1.5 cups lentils and 7 cups chicken broth (BTB works great) for a heartier soup 4. Juice of whole lemon at the end off the heat
