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.
PIN Italian Sausage, Tomato, and Pesto Soup to try it later.
For a few years now I’ve been having fun looking through the huge archives of my blog to find a recipe I have the ingredients for, and then updating it, often into an improved version 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, you can make this tasty soup with cauliflower rice, and I’m tagging this soup low-carb and gluten-free because it has those options.
And I know many people may not want to buy fresh basil, so I switched that out for basil pesto, which was absolutely delicious in this soup! So for everyone who needs comfort food while the cold weather approaches, 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.

How to make Italian Sausage, Tomato, and Pesto Soup lower in carbs:
This soup recipe as written with a small amount of macaroni has about 13 carbs in a serving. You can make it even lower in carbs by switching out the macaroni for Fiber Gourmet Light Elbows (affiliate link) or about 10 oz. frozen cauliflower rice. If you use cauliflower rice, this soup will also be gluten-free.
What gives this sausage, tomato, and pesto soup the Italian flavors?
Italian sausage, garlic, basil, ground fennel, and pesto all make this a soup that’s loaded with Italian flavor. But I think the ground fennel (affiliate link) is especially important here. Please don’t skip that!

I used turkey Italian sausage, but use pork Sausage if you prefer.
I would use 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:
Soup with macaroni would normally be too high in carbs for a low-carb diet, I didn’t use much macaroni here. Or use the option for cauliflower rice instead of macaroni or use Fiber Gourmet Light Elbows (affiliate link) to make a version that’s even lower in carbs. If made with approved macaroni, this Italian Sausage, Tomato, and Pesto Soup would be approved for phase 2 or 3 of the original South Beach Diet.
