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.

  4. Squeeze the sausage out of  casings and cook until nicely browned, breaking apart with a metal turner as the sausage cooks.
  5. Add browned sausage to the soup pot.

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. Glad you enjoyed the recipe!

  2. Basil, glad you enjoyed the soup and thanks for noticing the new blog design. I'm really liking it.

  3. Oh, I made a vegetarian version of this soup with fake meat, and it was sooo good and warming in this cold weather that I have been having recently. I love pasta soups, and this one made a huge batch. Great, healthy, warming, and not to hard to make either.
    The new layout for this blog is nice, too!

  4. Bob, sounds like an interesting variation.

  5. Tried it with a twist. I used Andouille sausage rather than Italian, and substituted some okra and Cajun spices for the basil.
    I also used whole wheat pasta to keep my blood sugar down.
    Turned out quite well for those of us who like spicy soups.

  6. Martha, that sounds like a good variation!

  7. Looks yummy. I have a very similar recipe to which I add a large back of frozen mixed vegetables!

  8. I'd love to hear how it turns out.

  9. That looks so freakin' delicious that I HAVE to adapt it to GF and veg (should be easy:-)

    Thanks Kalyn!

  10. Cindy, thanks for taking the time to let me know you liked the soup. And how fun that I've introduced you to fennel. It's definitely one of my favorite flavors.

  11. I made your soup recipe this evening and it was a big hit! Fennel is not one of the spices I use, so this soup gave me a new taste adventure.

    I follow your blog regularly and have tried several recipes which are now in my regular rotation.

    I also appreciate the comment from LibbyD about using meat with her own spices rather than the sausage. As I was making the soup, I wondered if it would be too bland (i.e., not salty enough), but found that the salt from the sausage was more than enough.

    Thank you for all the great recipes you create and share from other bloggers. It's much appreciated here in mid-Michigan.
