It was hot and sunny in Utah when I left for Thailand, and I thought maybe I’d have to save these new photos for Lentil and Sausage Soup with Sweet Potatoes and Herbs and update the recipe in the fall. Now I’m home from the trip and it’s cold and rainy here. And am I ever happy to be home, after getting bronchitis and having to stay several extra days in a hotel in Bangkok trying to get well enough to fly! So it’s definitely soup weather for me today, for more reasons than one.

I’m not back to feeling that good yet, but the post with 11 Favorite Recipes with Thai Flavors was up on the blog for days when I got stuck in Thailand, so I want to get something new posted before my jet-lag kicks in and I have to take a nap! It will probably take me a few more days to recover, but when I do I promise to share some photos and thoughts from the trip.

This soup is one that I first made back in 2007 when I was just starting to like sweet potatoes. It’s one of those soup recipes I just made up as I went along, and luckily I wrote down the recipe because it turned out to be a winner. Originally I roasted the sausage but when I updated the recipe for better photos I decided browning it in a frying pan would be an improvement because then you could deglaze than pan with extra water and add that delicious liquid to the soup.

Chop up an onion and saute in olive oil, adding the chopped herbs for the last minute you’re cooking the onion. Then add chicken stock and lentils and simmer 30 minutes.

Brown the turkey Italian sausage well. I like to brown the outside, then cool enough to cut it into half-moon slices and brown again, because the browning adds so much flavor, but you can just brown and slice if you’re rushed for time. Deglaze the pan with some water, scraping off the bits of sausage, and add to the soup.

Once the lentils have cooked about 30 minutes add the browned sausage pieces, a can of petite-dice tomatoes with juice, and the chopped sweet potatoes and cook at a very low simmer about 60 minutes more.

Season soup with salt and fresh-ground black pepper and serve hot. A great side dish for this would be Arugula and Gorgonzola Salad with Balsamic Vinaigrette.

Lentil and Sausage Soup with Sweet Potatoes and Herbs

This Lentil and Sausage Soup with Sweet Potatoes and Herbs was created when I just found some leftovers in the fridge and turned them into soup!


  • 1 large onion, chopped
  • 2 tsp. + 2 tsp. olive oil
  • 6 cups chicken stock
  • 2 cups water, plus more water as needed to deglaze the pan or thin the soup after soup simmers
  • 1 cup brown lentils
  • 1 T finely chopped fresh sage (can use frozen sage, if using dried sage use 1/2 T)
  • 1 tsp. fresh thyme (can use frozen thyme, if using dried thyme use 1/2 tsp.)
  • 5 links (19.5 oz.) turkey Italian sausage
  • 1 can (14.5 oz.) petite diced tomatoes
  • 1 or 2 large orange sweet potatoes, coarsely chopped (Orange sweet potatoes are often called yams or sweet yams in U.S. grocery stores)
  • salt and fresh ground black pepper to taste


  1. Heat the olive oil in the bottom of the soup pot, add the onion, and cook over medium-high heat for about 5 minutes, until the onion has softened.
  2. Add the sage (can use frozen sage ) and thyme (can use frozen thyme) and cook a minute or two more.
  3. Add chicken stock, water, and lentils and simmer over low heat while you cook the turkey Italian sausage and chop the sweet potato.
  4. Heat the other 2 tsp. olive oil to medium-high in a frying pan big enough to hold the sausage. Add sausage and brown the outside well. (Don’t rush this step, browning adds flavor.)
  5. Let sausage cool and cut in half lengthwise and then slice into half moon slices. (I like to put the cut pieces back in the frying pan again and brown the cut edges, but that’s completely optional.)
  6. Add about 1/2 cup of water to the pan and scrape up the browned bits from the sausage and add that liquid to the soup.
  7. Peel the sweet potatoes and chop into medium-sized pieces.
  8. After the lentils have cooked for 30 minutes, add browned sausage, canned tomatoes with juice, and chopped sweet potatoes and cook at a very low simmer about 60 minutes more, or until sweet potatoes are soft and starting to dissolve into the soup.
  9. Season soup with salt and fresh ground black pepper and serve hot.

Low-Carb Diet Low-Glycemic Diet / South Beach Diet Suggestions:
This Lentil and Sausage Soup with Sweet Potatoes and Herbs would be good for phase two of the South Beach Diet. Lentils and sweet potatoes are both relatively high in carbs, so this is not suitable for low-carb diets, but you could reduce the carbs in this recipe by using more sausage and less lentils and sweet potatoes.

  1. Lentil soups cure anything that ails you! Thanks for linking to my cure-all lentil soup recipe.

  2. Sounds yum with all my favourite things in it. Have a thought at the back of my mind to try it with chorizo instead of turkey sausage. Not as healthy but I can't be good all of the time.

  3. This soup sounds delicious.. I make one similar with butternut squash instead of sweet potatoes but I will have to try this one also. Thanks for sharing.. Marsha

  4. Kelsey, I haven't used sprouted lentils but I don't see why they wouldn't work. That's fun about the cooking.

  5. Could I use sprouted green lentils? It's what I have in the cupboard. SBD has really helped me learn how to cook.

  6. I kind of combined this soup with the Lentil and Ground Beef Soup recipe you posted around the same time. I basically used ground turkey instead of the sausage and used half beef broth (sadly, from a can — but the chicken stock was homemade!). It was very easy and came out with a really nice, mellow flavor. Good comfort food that’s actually healthy. 🙂

  7. Diane, so glad to hear you liked the sweet potato fries recipe so much, especially since I’ve giving everyone at my school a little packet of that spice mix for Christmas. (Now we will see if any of them find this comment before then! I know some of them read the blog, but I doubt they read the comments.)

  8. Now that it’s fall I’ve been on a total sweet potato kick. Broken only by an occasional foray into squash. I made your Sweet Potato Fries recipe last week, and in the past week have made it twice again since that first time. Mmmmmmmmm…it is excellent!

  9. Thank you thank you! I’ve been looking for something yummy to make with sweet potatoes! Just the ticket 🙂

  10. I like thick soups like this.

  11. The thing I love about lentil soup is that everyone has a favorite version, and no two are exactly the same. This looks delicious and incorporates sweet potatoes, which I’ve promised to eat more often in the coming year.

  12. I made this soup today and it was delicious. I did make one adddition. When we were on a cruise recently we had a soup similar to this that included okra. So I tossed in about a cup of frozen sliced okra. This recipe is going into the “make again” file. Thanks, Kalyn–Jancd

  13. This soup sounds good. Sausage and sweet potatoes sound like a nice combo. I keep meaning to try lentils again…

  14. Tanna, you’re right, it’s everywhere. I love them all.

    Katie, me too. Lentils are so comforting for some reason! (And very SB friendly too!)

    Ta, thanks for sharing your South Beach success with us, and congratulations! Glad to hear you are enjoying the blog.

  15. I am loving your blog. I started SBD 2 weeks ago and have lost 11 lbs. It’s so great to find new recipes. Thank you so much.

  16. I love lentil soups. The sweet potatoes seem right for that soup…, especially with the sausage. I’m with you on making soup in winter. I could easily live on it…actually, I do have it for lunch most days!

  17. Very interesting how this color (sweet potato, squashs) seems to be dominating lots of posts these days.
    Yes lentils – I think I have some needing to become soup! Thanks Kalyn, again.

  18. Jeanne, me too. Wish we could just stay home from work and eat soup, don’t you?

  19. Oh this looks tremendous! I love sausage and I love lentils – and the weather is much chillier now than last week. Plus I feel a bit sniffly and sorry for myself today, so this looks double tempting!
