Why This Recipe is a Keeper!

Spicy Italian sausage.  Earthy lentils.  Vegetables like onion, celery and carrots in a spicy, tomatoey broth with kale.  Oh my!

Dried lentils are something I always have on hand.  I love them!  They make for an inexpensive meal or addition to a meal at any time of year.  They also work in salads, and you can use them in almost any way you would like rice or quinoa.

Besides being versatile, they’re good for you!  They’re loaded with plant protein and iron.

Sausage and lentils are a match made in culinary heaven; in a soup like this Sausage Lentil Soup with kale, they’re culinary magic!

Makes great leftovers! This hearty Sausage Lentil Soup recipe also freezes and reheats beautifully!

Ingredient Notes and Substitutions:

  • Italian Sausage: Use mild or spicy, depending upon your tolerance. You can also substitute turkey or chicken Italian sausage. If you do that, use chicken or vegetable broth instead of beef broth.
  • Brown Lentils: Brown lentils are the most common type of lentil widely available at most grocery stores near dried beans and rice. They cook reasonably quickly–20 to 25 minutes. You can substitute green lentils but allow an additional 20-25 minutes of cooking time. I don’t advise using red lentils because they break down too much after cooking.
  • Petite Diced Tomatoes: Petite diced tomatoes are about half the size of diced tomatoes. Although the sausage lentil soup will be more chunky, you can substitute diced for petite diced. Another option is to use kitchen shears to chop the diced tomatoes more finely, which you can do right in the can.
  • Kale: I used regular green curly kale, but any kale can be used. You can substitute other leafy greens such as spinach or Swiss chard.

Step-By-Step Instructions:

  • Start by inspecting the lentils.  See my tips below on how to do that.
  • Cook the lentils separately before adding them to this soup.  Place the lentils in a saucepan of water and bring to a boil.  Cook for a half hour or until the lentils are tender.
  • When the lentils are cooked, drain, rinse to cool, then drain again.  Set aside.
  • Brown the sausage over medium-high heat, then transfer to a plate.

That’s it!

If you prefer, you can always substitute turkey sausage or chicken sausage.  If you do that, substitute the beef broth with chicken stock or chicken broth.

How to Inspect Lentils for Debris:

One thing you always want to do when working with lentils is to look them over well for stones, twigs, and odd-looking shriveled ones because those can be stone-like.

What I do is:

  • Place a small amount–about 1/4 cup–on a plain white paper plate.  A white surface makes debris easier to find.
  • Look them over for any odd things and discard them.
  • Then, gently fold the plate to guide them into your pot or into a bowl.
  • Repeat with the remaining lentils.

Chef Tips and Tricks:

  • I like to cook lentils separately because all the starch they give off can make a soup murky….and who wants that?  Soups tend to thicken upon standing, especially those with anything starchy, like lentils.  Cooking them separately will help prevent that.  Also, anything acidic, like the tomatoes, or salty, like the broth in this recipe, may cause your lentils to take longer.
  • A soup-making tip I’ve learned over my years as a personal chef is to let the soup “rest” approximately 15 to 20 before serving.  It will be unbearably hot anyway, so let those flavors meld and get to know each other a little bit.

Stay well and enjoy this delicious, hearty Sausage Lentil Soup!

Frequently Asked Questions:

Can I use turkey or chicken Italian sausage instead of pork?

Yes, absolutely! You may wish to switch out the beef broth for chicken or vegetable broth if using turkey or chicken Italian sausage. You could substitute ground meats such as beef, turkey, or chicken; however, the flavor will be much milder.

Do you need to soak lentils before cooking?

It’s optional. You don’t need to, but soaking them is fine if you want them to cook faster.

Can I make lentil soup in a slow cooker?

Yes, you can! If time allows, I would soak the lentils first to remove some of their starch. Brown the sausage, combine all the ingredients, then cook on low for 7 to 8 hours.

    Love this soup. I pared it down to almost half because it requires at least a 5 quart Dutch oven and mine is only 3 1/2 quarts. Otherwise my only addition was Parmesan rind which I think added to the taste.
    Up next. Thai Red Curry Chicken Legs.

    1. Hi, Yvonne, Thanks so very much and so happy you enjoyed! Parmesan rinds definitely add to the flavor so good call!! Appreciate your taking the time to come back and comment.

    This is a family favorite. I make it when I’m expecting out-of-town family but don’t know their exact after 5 pm arrival time. It keeps beautifully and satisfies hungry travelers. I’ve adapted the recipe for the slow cooker with great results.

    I made a double batch of this recipe with more of the vegetables added. My family loved it, and my father, who is a health nut just raved about it. I did let it simmer on low for a couple of hours. I made it the day before, so it was perfect. Just kept on warm until the family came over.

    1. Hi, Aly, Thanks for your question. Yes, you absolutely can. Just drain and rinse them well and add them near the end. Thanks again and hope you enjoy!
