How to Make Italian Sausage Soup with Tomatoes and Zucchini Noodles:
(Scroll down for complete printable recipe.)
- Heat a little oil in a large frying pan, squeeze the turkey sausage out of the casings, and brown it well.
- Add the browned sausage, canned chicken broth (affiliate link), canned petite dice tomatoes, tomato paste, and spices to the soup pot and start to simmer.
- Chop up the red pepper, green pepper, and onion and saute for a few minutes; then add those vegetables to the soup and simmer on low for 30-60 minutes.
- After the soup has simmered for a while, use a Spiralizer (affiliate link) or other method for making zucchini noodles of your choice. I used my Paderno Spiralizer (affiliate link) and cut a slit along zucchini and used the thick blade to make short curved noodles that slightly resemble macaroni.
- Add noodles to the soup and simmer on low for 20-30 minutes more.
- Serve Low-Carb Italian Sausage Soup with Tomatoes and Zucchini Noodles hot, with a little freshly grated Parmesan to sprinkle on top if desired!

- 19.5 oz. pkg. turkey or pork Italian Sausage (see notes)
- 1 T olive oil
- 8 cups homemade chicken stock (Or use 64 oz. stock from a carton or can if you prefer.)
- 2 14.5 oz. cans petite diced tomatoes
- 2 T tomato paste
- 1 T dried basil
- 2 tsp. dried Greek oregano
- 2 tsp. ground fennel (probably optional, but I love the flavor of this)
- 1/2 large red bell pepper, chopped (or use the whole pepper if you prefer)
- 1/2 large green bell pepper, chopped (or use the whole pepper if you prefer)
- 1/2 medium onion chopped
- 2 medium (10 inches long) zucchini
- salt and fresh-ground black pepper to taste
- Heat 2 tsp. olive oil in a large non-stick frying pan, squeeze sausage out of the casings into the pan, and cook until all liquid is evaporated and the sausage is nicely browned, about 10 minutes. (I browned the sausage in my favorite Green Pan (affiliate link). I like to use an old fashioned potato masher (affiliate link) to break the sausage apart.)
- When the sausage is nicely browned, add it to a medium-sized soup pot with the chicken stock, canned tomatoes and juice, tomato paste, dried basil, dried oregano, and ground fennel. Let the mixture start to simmer over low heat.
- While soup simmers, chop up the red bell pepper, green bell pepper, and onion. Heat the other teaspoon of olive oil in the same pan you browned the sausage in and cook the peppers and onions for a few minutes, then add to soup pot.
- Let the soup simmer on low for 30-60 minutes. (Sixty minutes is best, but you can get away with a less if you're short on time.)
- After soup has simmered for a while, make the zucchini noodles. Wash the zucchini and pat dry, then cut off both ends and cut a lengthwise slit going halfway through one side of the zucchini. Use a Spiralizer (affiliate link) on the thicker noodle blade (or other method for making zucchini noodles of your choice) to make thick half-noodles (Making a slit in the zucchini makes short noodles instead of one long one. You can see photos of the cut zucchini and short noodles here.)
- Add noodles to the soup and simmer 20-30 minutes more, depending on how done you like the zucchini.
- Season to taste with salt and fresh-ground black pepper and serve hot, with freshly-grated Parmesan to add at the table if desired.
Use hot or sweet sausage, but I like hot sausage for this soup.
