This Italian Sausage, Zucchini, and Macaroni Soup is favorite soup that I first made years ago, and since then I’ve made it many times for family get-togethers, or for my annual New Year’s Day soup party. It’s perfect for this time of year when the nights are getting cooler, but there’s still zucchini from the garden to be used.

If it’s starting to get a little cold where you are and you happen to have some zucchini, I highly recommend this as a good soup to help you transition to the new season.  In fact, this soup is worth making even if you have to buy zucchini!

What ingredients do you need for this recipe?

 What if you don’t have fresh basil?

I use my frozen chopped basil for soup if I have some, or you can use purchased basil pesto in the soup.

How can you make a lower-carb version of this soup?

For a lower-carb version of this recipe just use more sausage and less pasta or skip the macaroni and use more zucchini.

How to Make Italian Sausage, Zucchini, and Macaroni Soup:

Scroll down for complete recipe with nutritional information.)

  1. I’ll normally use Jenni-O Hot Turkey Italian Sausage for this soup, but you can use pork sausage if you prefer.
  2. Heat a small amount of olive oil and brown the sausage well. Don’t rush this step; the browning adds flavor!
  3. If your sausage is raw, you’ll need to brown the whole links first it to get it firm enough enough to slice.
  4. While the sausage browns, start simmering the chicken stock, roasted or canned tomatoes, dried oregano, and dried basil in soup pot.
  5. When the sausage is browned, add it to the soup pot. Saute the onions and garlic in the same pan you used to brown the sausage, then add those to the simmering soup as well.
  6. Deglaze this pan with 1 cup of water and add to the soup.
  7. Dice up enough zucchini to make about 2 cups of diced zucchini. Measure 1 cup of dried whole wheat macaroni. I used my frozen chopped basil for this, (which is a good reason to be freezing basil for winter!)
  8. Add zucchini to the soup and simmer 15 minutes.  (If you’d like a low-carb and gluten-free version of this soup, use a little more zucchini and skip the macaroni.)
  9. Then add the macaroni (plus another cup of water if needed, which it probably will be.)
  10. Simmer soup about 15 minutes more, or just until the macaroni is done.
  11. Stir in the chopped fresh basil (or frozen chopped basil) and cook just a couple of minutes more.
  12. Serve soup hot, with plenty of freshly grated Parmesan for people to add at the table.

  4. While sausage browns, combine homemade chicken stock, oregano, canned tomatoes or slow-roasted tomatoes, and basil in medium stock pot and start to simmer.
  5. When sausage is thoroughly browned, add it to stock mixture.

  16. Cook 5 minutes more.

If you don't have homemade chicken stock, use four 15 oz cans cans chicken broth, which might need to be simmered a bit longer.

For a lower-carb gluten-free soup skip the macaroni and use a  more zucchini.
