Sometimes I feel like a very bad blogger indeed!  This week food bloggers everywhere are posting Superbowl party food and I’m over here sharing updated photos for this deliciously healthy Sausage, Lentil, and Roasted Red Pepper Soup. Of course, if you’re looking for carb-conscious Superbowl recipes, there’s a round-up of 50+ Low-Carb and Gluten-Free Superbowl Appetizer Recipes, but since the entire east coast of the U.S. is snowed in, it seems like soup is a good menu choice for lots of people.  There’s not much snow right now at my house, but I know we’ll have plenty more snowy days before spring, and when we do I have a few containers of this soup in my diet-friendly freezer!

I did change the recipe slightly for this update, using a whole package (19.5 oz.) of sweet turkey Italian sausage, which makes this a more carb-conscious recipe.  Lentil are high in fiber too, so I think this soup would be a good choice for any type most low-carb eaters with that change.  And more sausage, mmm.  I love all the flavors in this soup, hope you enjoy.

Brown the sausage well and put it in the soup pot.  (I use Jenni-O Turkey Italian Sausage, which is gluten-free, but use pork Italian sausage if you prefer more fat.)  Then brown the onions and add to the soup pot with the chicken stock, lentils, ground fennel, thyme, and sage.   Drain the roasted red peppers while the soup simmers until the lentils are tender, about 45 minutes.

When the lentils are tender, chop the roasted red pepper and add to the soup; then let it simmer about 45 minutes more.

Sausage, Lentil, and Roasted Red Pepper Soup

Sausage, Lentil, and Roasted Red Pepper Soup is one of my favorites and this delicious soup makes a great cold weather meal.


  • 1 package (19.5 oz.) turkey or pork Italian Sausage
  • 2 tsp. olive oil (or more, depending on your pan)
  • 1 onion, diced into small pieces
  • 1 cup brown lentils
  • 6 cups homemade chicken stock (or use 3 cans chicken broth plus a little water)
  • 2 tsp. ground fennel (do not leave out)
  • 1 tsp. dried thyme
  • 1 tsp. rubbed sage (dried)
  • 1 12 oz. jar roasted red pepper


  1. Heat olive oil in heavy frying pan, add Italian sausage and brown well, breaking sausage into pieces as it cooks. (I like to use an old-fashioned Potato Masher (affiliate link) to break the meat apart.)
  2. Add sausage to soup pot.
  3. In same pan, adding more oil if needed, brown onions until softened and barely starting to brown.
  4. Add onions to soup pot.
  5. Rinse out pan with 1 cup homemade chicken stock , then add to soup pot along with rest of stock, lentils, ground fennel, thyme, and sage.
  6. Cook at lowest possible simmer for about 45 minutes, until lentils are softened, but still holding their shape.
  7. Drain the roasted red peppers while the soup simmers, then chop into pieces about 1/2 inch square.
  8. Add red pepper to soup and cook about 45 minutes more (adding a little more stock or water if needed), until some lentils are starting to fall apart and all flavors are well blended.
  9. Season with salt and fresh ground black pepper and serve hot.

Low-Carb Diet / Low-Glycemic Diet / South Beach Diet Suggestions:
With turkey Italian Sausage, this Sausage, Lentil, and Roasted Red Pepper Soup would be acceptable for any phase of the South Beach Diet and it’s also great for other low-glycemic eating plans. Lentils are considered a “good carb” for South Beach, but limit them to a small serving for phase one. Even though there’s a generous amount of sausage in this soup, lentils are probably too high in carbs for it to be considered a low-carb soup. You could use less lentils and more sausage if you wanted a soup that was lower in carbs, and use pork Italian Sausage if you prefer

Blogger Disclosures:
This delicious lentil soup was first posted in 2007 for Peabody’s virtual housewarming party and I’ve enjoyed it many times since then.  Photos were updated January 2015.

I recommend gluten-free Jenni-O Turkey Italian Sausage for this soup, but Jenni-O has never paid me to promote their products and I’m pretty sure they don’t even know I’m alive!  (I don’t accept payment to promote products and only recommend things I love enough to buy myself.)

  1. Help! Never cooked lentils before. 2 questions:
    Do I need to rinse and soak the lentils before adding them to the recipe?
    Where do you find brown lentils? I looked at several grocery stores. They have every other color. Can you substitute with a bag called lentils? Some look green some look light brown (maybe?) Thank you soooo much

    • There is no need to soak lentils before cooking, but I usually rinse to remove dust and pick them over. (Sometimes they even have little rocks in them.) Brown/green lentils are pretty much interchangeable. I’m sure any bag that just says lentils is going to be fine! Hope you enjoy!

  2. The fennel makes all the difference! Very tasty.

  3. Thanks CJ, I love, love, love this soup. I need to make it again soon.

  4. The pics look amazing as is!! Thanks for this one. I love using lentils, but it can be hard to find good recipes that don't involve curry flavors. DBF isn't the biggest curry fan, and I grow tired of it after awhile. We'll definitely be trying this one!

  5. Great idea to add the kale. And I really want to take new photos for this soup!

  6. So yummy, I also added a handful of baby kale in the last 7 minutes to add a few more vitamins :). Filling and perfect for a cold day.

  7. Kendra, so glad you like it. I love ground fennel!

  8. I've made this soup twice now and LOVE it. I tried it before adding fennel, by the way, and it does make a big difference. It's so delicious! What's more, my four year old AND one year old love it!

  9. Amanda, so glad you're enjoying it!

  10. I've made this soup about 4 times now and it's delicious and savoury every time. I freeze portions to bring for lunch. Thanks Kalyn.

  11. You're welcome; I'm glad you enjoyed it!
