I adapted this recipe from one by Alton Brown. I added spinach, potatoes, and scallions and removed grains of paradise. Our whole family really enjoyed this recipe. I made it alongside an Indian curried lentil soup recipe, and while both were good, this was the hands down winner. If you're looking for a tasty, hearty, and healthy soup to serve this winter, look no further!

  1. Place the olive oil into a large 6-quart soup pot or Dutch oven and set over medium heat. Once hot, add the onion, carrot, celery and salt and sweat until the onions are translucent, approximately 6 to 7 minutes. (If you are concerned about salt intake, use just 1 teaspoon and serve additional salt on the table for those who want more.)
  2. Add the lentils, potatoes, tomatoes, broth, coriander, cumin and stir to combine. Increase the heat to high and bring just to a boil. Reduce the heat to low, cover and cook at a low simmer for about 25 minutes. Add the frozen spinach and continue to cook until the lentils are tender, approximately 10 to 15 minutes.
  3. Optional: Using a stick blender, puree approximately a quarter of the soup or more to your preferred consistency. Top with chopped scallions as desired and serve immediately.
  4. Suggestion: This is a very flavorful soup, but since the recipe did not call for any black pepper or other hot spice, I served a red pepper sauce (Sriracha) on the side for people to add as desired.

      Made a double batch of this tonight for the family tonight, and it was great! I've always liked lentil soup but other family members did not share my enthusiasm; had I but known, it was my PREVIOUS recipe that was at the heart of their lack of excitement for the small brown bean, I'd have switched years ago!
      The only change I made was to add ham, and the broth was from the hock the bit of ham came off of. The other part of the recipe, "How much to puree in the blender?" I answered with ⅓. Thank you so much for this delicious soup!!

        Our kids absolutely loved this recipe, and so did I. It was full of flavor and just the right level of thickness. Next time you are thinking of having split pea or bean soup, try this out instead!

            I made the soup last night using turkey/chicken stock. Added 1 tsp salt and no pepper. Tossed in a couple chopped pieces of cooked bacon at the end . It tasted great!

              I think I'd try this- only leaving out the scallions because hubby cannot onions or scallions but we both love spinach. how do I print this recipe?

                  Hi Dena - one cup of lentils is about six ounces. So 2 2/3 cups per pound.
