Lentil Soup with Sausage and Roasted Red Pepper is one of my favorite soups, and I love how spicy Italian Sausage adds flavor to this soup!

Right now the entire east coast of the U.S. is snowed in, so it seems like soup is a good menu choice for lots of people. And even though there’s not snow at my house I’m glad I just updated the photos and I have some of this Lentil Soup with Sausage and Roasted Red Pepper in the freezer!

I did change the recipe slightly for this update, using a whole package (19.5 oz.) of turkey Italian sausage which makes this a more carb-conscious recipe. Lentils are high in fiber too, so I think this soup would be a good choice for most carb-conscious eaters with that change, although it’s probably not suitable for people who are strictly limiting carbs.  And more sausage, mmm.  I love all the flavors in this soup, hope you enjoy.

How to Make Lentil Soup with Sausage and Roasted Red Pepper:

(Scroll down for complete recipe with nutritional information.)

  1. Brown the sausage well and put it in the soup pot. I recommend gluten-free Jenni-O Turkey Italian Sausage for this soup, but use pork sausage if you prefer. Use either sweet or hot Italian sausage, whichever you prefer.
  2. Then brown the onions and add to the soup pot with the chicken stock, lentils, ground fennel, thyme, and sage.  
  3. Drain the roasted red peppers while the soup simmers until the lentils are tender, about 45 minutes.
  4. When the lentils are tender, chop the roasted red pepper and add to the soup.
  5. Then let soup let it simmer about 45 minutes more, or until lentils are as soft as you prefer and flavors are well blended.
  6. Season with salt and fresh-ground black pepper and serve hot.

Instructions

  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.)

  4. Add onions to soup pot.

  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.

Notes

Use turkey or pork Italian sausage. whichever you prefer. Use sweet or hot Italian sausage. If you don't have homemade stuck, use 3 cans chicken broth plus a little water.

Low-Carb Diet / Low-Glycemic Diet / South Beach Diet Suggestions:
With turkey Italian Sausage, this would be acceptable for any phase of the oroginal 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

  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!
