It takes just 5 minutes to “throw” everything in a pot, and turn on the burner. No frying, no sautéing, the heat does all the work, turning your ingredients into the most delicious, healthy, unprocessed soup!

Just how healthy can this little legume be? Well, lentils are great for lowering cholesterol, they’re high in fiber, and iron (great for vegetarians). This Italian lentil soup recipe is the antithesis of oxtail soup which takes a lot of time and effort to make, although I think it’s worth it if you have the time.

Why not also try this Scottish red lentil soup. It’s another delicious option, but uses red lentils.

Lentils also fill you up so you eat less! I always have at least one bag in my pantry, but those of you in colder climates would do well to stock up with a few bags. And as with many dishes from Italy, this Italian lentil soup uses a handful of ingredients.

Bring to a boil, over medium high heat, then simmer over med-low heat, (adding more water if necessary) stirring occasionally, until lentils are done–about 30 mins.  5 minute lentil soup won’t win any beauty contests, but you won’t care when you taste it.

Serve immediately, and enjoy with some fresh, crusty bread! I love a little extra freshly ground pepper on mine.

  1. Born and raised in Germany we had Lentilsoup on the Table a lot and it’s still one of my favorite soups . After moving to the United States many years ago that was one of the dishes I did not need to read a cookbook for , learning how to convert from metric to cups and ounces .My husband learned to love it over the years and my girls now cook it for their families .Never run out – always buy two bags – one for now and one for later :-) since I have to cut down on Salt I played with spices and add a little cumin and about a teaspoon of curry to the soup . Otherwise our recipes are identical . Thanks for posting and I really look forward to your posts . Lots of bringing me back to the days when my family traveled Italy during the summer break while I grew up . Thank you – greetings from Indianapolis IN

  2. Thanks Christina!!! Made the Lentil Soup as per your recipe and it couldn’t be easier and tasted like my Mom’s! I did add the chopped spinach because my husband and I both spinach. No more canned lentil soup in our house! Soooo easy and only one pot!

    1. Woo hoo! Love to hear that, Joanne! If only everybody knew how easy this is, we’d have a country of lentil soup lovers! Thanks so much for letting me know! :)

  3. Lentil soup is a long standing family comfort food for me. Try adding a tsp or two of porcini mushroom powder for an even deeper flavor.

  4. Hi Christina….It’s been awhile since I commented (due to computer problems) but I do read every one of your emails! I love Lentil soup! I knew that lentils cook fast but I did not know that I could put everything together with the beans and cook it all at one time!!! Thank you! I bought dried lentils after Thanksgiving but just keep looking at them when I opened the pantry door. With your recipe, and I have all the ingredients on hand, I will make this tomorrow! We are having extremely cold weather here in the South so this dish will be perfect! I grew up with Lentil Soup….my Italian Mom made it often in the winter but she always cooked the beans first and I guess that is why I still have the dried lentils in my pantry! She also added a little chopped spinach to her lentil soup and if you like spinach it is delicious with the lentils and even more healthy!

    Grazie!
    Molta fortuna, salute e felicita nel nuovo anno,

    1. Hi Joanne! Nice to hear from you again! Thank you for your lovely comment. I’m glad you’ll be able to stop looking at the lentils in your pantry (haha!) I’m sure you’ll love this soup, and yes, I can imagine, spinach would be a fabulous addition. In fact, I think I will try that next time. Why not add even more goodness to this soup? Let me know how you like it and Happy New Year to you, too! :) Christina
