Cold out? Need something to make you feel warm and cozy. Well, this soup does the trick.  

The lentils, slow-cooked with the pancetta, veggies, and stock will definitely warm you to the core. We give it a true Tuscan twist and add sweet Italian sausage, along with the pancetta. But, you can easily make this vegetarian by omitting the pork and use vegetable stock.

This soup is not difficult to make at all. All you need are less than a couple of hours to let the deeply flavorful stock do its work on the dried lentils, and you’ll have one of the most comforting soups you’ve ever had or made.

We love to go with green lentils, but you can go with whatever type of lentils they have at the market.

Watch us show you how easy it is to make this incredibly delicious soup!


Pancetta is similar to bacon in that it is pork belly that is cured. All we can say it is loaded with flavor and is very popular in Italian cooking, especially in soups and pasta.

Once the pancetta has cooked and gotten nice and crispy, it’s time to add the mirepoix (onions, carrots, and celery). You’ll need to saute them for about 5 to 8 minutes, or until they have become soft and translucent.

The garlic and fresh herbs added to the mix help to create a foundation for this Rustic Lentil Soup that is just perfection.

Next, you’ll need to add the tomato sauce and the chicken stock. Homemade stock is always the best for soups, but a good-quality purchased stock, or broth, will work just fine, too.

Bring the liquid to a boil, and then lower the heat to a simmer, and then gently add the lentils.

EXPERT TIP: You’ll need to keep an eye on the soup as it simmers for a couple of reasons, you don’t want it to start to burn on the bottom of the pan, which is why occasional stirring is necessary. Also, after about a half-hour of simmering, as the lentils absorb the liquid, the soup may become too thick. If this occurs, simply add more stock to reach the consistency you prefer.

As we discussed, this soup can absolutely be 100% vegetarian by omitting the pancetta and sausage and using vegetable stock in place of chicken stock.

But folks, we must say, the small bite-size pieces of sausage in the soup is pretty awesome.

Simply purchase Italian sausage links (sweet or hot), remove the casings, and then form little sausage balls. Cook them up in a skillet with a dash of olive oil, and you’re good to go!

To make the soup even more hearty and delicious, we add cubed russet potatoes.

Peel the potatoes and cut them into small, bite-sized cubes and then drop in them in the soup after 40 minutes of cooking.

EXPERT TIP: The smaller the potato cubes, the less amount of time they’ll need to simmer in the soup to become soft and edible. Cubes about ½-inch thick will take only about 15 minutes to become perfectly tender. Again, keep an eye on the soup, at this point, there is a good chance you’ll need to add more stock to keep the soup from becoming too thick.

This is also a good time to slice and toast some nice crusty Italian bread.

And did we mention the smell? Oh good heavens, this is the good stuff.

This soup is wonderful on so many levels. Comforting, yes, but because lentils are loaded with so much nutritious goodness (i.e., iron, fiber, etc), this soup is good for you, too!

And did we mention how delicious it is?

Oh my! Just look at this bowl of goodness!

This soup is perfect for a chilly day, or anytime you’re in need of a good bowl of comfort.

The soup will keep in the refrigerator for up to 1 week and in the freezer for up to 2 months.

Green lentils work well with this soup, but so do red or brown.  Whatever is available at your supermarket will work.  You will find dried lentils in the dried beans section of the grocery store.
If using dried herbs, use half the amount called for in the recipe.
Keep extra stock on hand, in case the soup gets thicker than desired.  Simply add the stock until you reach the desired consistency.
Omit the pancetta and sausage, and use vegetable stock/broth, in place of the chicken stock, to make this soup vegetarian.
The soup will keep in the refrigerator for up to 1 week and freezes beautifully for up to 2 months.

    Hi guys! Made this today using some homemade stock that I had frozen from your recipe, of course. This was DELISH. I omitted the potatoes because I added some ditalini noodles that I just can’t resist in any soup. I also added some sweet Campari tomatoes because they needed to get used up before the trash. Seasonings were spot on with just a little bite with hot sausage. Way to go bringing us another winner soup. This is right up there with your tomato basil. I can’t wait for my staff to have it for lunch on Monday. Pretty soon I’ll be flying to make recipes with you guys! Kris, Loon and D show LOL

    Ok guys,
    I am literally eating a big bowl of this amazing lentil soup while I’m typing this review.
    I couldn’t wait to tell you . Best lentil soup we have ever had! I used Hillshire Farms smoked sausage instead of Italian sausage because my husband prefers it. Just sliced it, browned it and threw it in. Served it with buttered sourdough bread cooked under the broiler, so crunchy and good. The only downside is it makes our 3 mini doxies, Daisy, Abby and Ushi, crazy the whole time it’s cooking because it smells so fabulous. My heart goes out to Eb & Flo! Would love to see more pics of them.
    So thank you, thank you, thank you again for bringing much happiness into our lives. Tomorrow it’s Chicken Enchiladas Verde, yaaayyyy! Hasta luego mi amigos

    • Darlene!! You made us get all misty!! We are THRILLED you enjoyed the lentil soup, and your additions with the crunchy sourdough bread and sausage are making us drool!! And Eb and Flo send their love! We’ll make sure to include more pics of them. They are always very nearby, especially when we’re cooking!! And let us know how the enchiladas turn out! They are one of our all-time favorite TexMex recipes!! All the very best, Kris & Wesley
