Italian Sausage, Tomato, and Pesto Soup

Italian Sausage, Tomato, and Pesto Soup can be made with macaroni or frozen cauliflower rice, and this is an easy soup the whole family will enjoy! And I didn’t use much macaroni, so even if you choose that option this soup isn’t very high in carbs.

How’s everyone doing with the voluntary home confinement? I’m staying home to be safe and keeping myself fed and relatively entertained, but definitely struggling with a lack of motivation to think of new recipes for the blog! I can’t seem to find the desire to work on new recipes when I know people may not have the ingredients and probably won’t want to go out to the store to get them.

But what I have been having fun doing is looking through the huge archives of my blog to find a recipe I have the ingredients for, and then updating it into an improved version, often with lower carbs or at least a lower carb option. And that’s what I did with this recipe for Italian Sausage, Tomato, and Pesto Soup!

The original recipe was one I came up with years ago for a family party, and it had twice as much macaroni as the newly updated recipe you see here. If you don’t want even the smaller amount of macaroni I used or want a soup that’s gluten-free, you can make this tasty soup with cauliflower rice. And I knew most people wouldn’t have fresh basil on hand right now so I switched that out for basil pesto, which was absolutely delicious in this soup! 

I shared some of the soup with my sister Pam and her husband Kelly one day when we went for a walk (staying appropriately at a distance from each other) and they both gave it a thumbs up! And I’ve definitely noticed that comforting dishes like soup, stew, and casseroles are what many people are cooking these days! So for everyone who needs comfort food and is still enjoying soup, I hope you’ll give this improved recipe a try! And here’s the link to the original version, just in case anyone was a fan.

Notes

You can also use two 32 oz. cartons of chicken stock or five 14 oz. cans of chicken broth. I used my favorite turkey Italian sausage, but use pork Italian Sausage if you prefer. I would love using my frozen Basil Pesto with Lemon for this recipe, but I just use my favorite purchased pesto when I don't have any homemade pesto in the freezer.

Low-Carb Diet / Low-Glycemic Diet / South Beach Diet Suggestions:
If made with approved macaroni, this Italian Sausage, Tomato, and Macaroni Soup with Basil would be approved for phase 2 or 3 of the South Beach Diet. Soup with macaroni would probably be too high in carbs for a low-carb diet, but if you want a lower-carb soup with these flavors, use the option for cauliflower rice instead of macaroni. (Macaroni adds about 5 carbs per serving, cauliflower rice is about 1.5 carbs per serving.)

  1. Sara, thanks. I don't know if you knew that I was a teacher for 30 years, so I love hearing that I am inspiring students to cook!

  2. Hi Kalyn!

    I made this tonight to keep me going through final exam revisions, and it was great! Plus, now I have a freezer full of leftovers. So simple and cheap to make and it seems like it would be fun to play around with too (like maybe adding beans as another commenter said). Not that it needs any changes at all. 🙂

    Your recipes are a godsend to any university student. Thanks Kalyn!

  3. I think chopped kale or thin ribbons of kale would be a great addition to this soup. I'd add the kale when you add the macaroni, unless you like it a little more crisp, then I'd add it when the macaroni is partly cooked. Love to hear how it turns out!

  4. Sounds great and I look fwd to making it tomorrow evening. However, not having tried it yet, so not being exactly sure of the flavors, do you think that kale would be a good addition in this soup? Thanks!

  5. Anonymous, that would work well if you're making the soup to freeze.

  6. Just another idea – I usually freeze my soups in the stage before adding the pasta/noodles and include it to cook when I'm heating the soup to serve.

  7. I need one now! Wow, this soups looks delicious and soul reviving in the wintry days here in UK. Nice blog and I love the blue bowl and plate.

  8. Perfect macaroni soup! Good for this season.

  9. Looks delicious. I bet you could throw in some white beans too for some extra fiber and yum.

  10. That is a tasty looking soup!

  11. Kalyn…this sounds so great! I always do the same type of soup but this would be a great alternative with the sausage and macaroni!

  12. This soup looks beautiful, I want to try it, but I think, I have leave it on weekend.

  13. CJ, I don't think any recipe could have too much fennel, absolutely love that flavor.

  14. Oh how we love soups this time of year, especially the hearty ones. I make a similar soup and sometimes add some drained and rinsed cannelini beans to it too. That idea came about out of necessity. Had some unexpected company and needed to extend the soup. It worked.

    This recipe looks mouth wateringly delicious. I'm so glad I have fresh basil in the freezer! I like the extra fennel in it too. A woman of my own heart.

  15. Libby, you sent me to the freezer to look at a package of sausage, and there was more sodium than I realized, so great idea to make your own with spices!

  16. I hesitatae to buy sausage because I must keep my salt down, so now I stir-fry a mixture of ground pork and beef plus all the seasoning s that you would find in a particular typre of sausage, i.e. for Italian: garlic, oregano, thyme, chili pepper: for mid East recipes I add garlic, cumin, coriander, paprika, hot sauce. This way I get all the flavours wothout the high sodium .

  17. I would love to have some of this soup hanging out in my freezer right now. M-m-m-m.

  18. Whenever it gets cold here, all i want to do is curl up and eat something that's going to warm me from the inside out. This sounds perfect!

  19. LOVE the bright new look of your blog! So pretty!

    And thanks for another flavorful Kalyn Soup. ((I have made several of yours and they have all been delicious.))
