This Zucchini Tomato Italian Sausage Soup is a delicious way to use up all of those fresh garden vegetables!

Our backyard garden is on the brink of starting to produce massive amounts of fresh zucchini and tomatoes, and I can’t wait! Especially because I know that Jack will be cooking up a batch of this fantastic Zucchini Tomato Italian Sausage Soup!
Now, I know that some of you may be thinking that a hot soup is the last thing you’d think about cooking in the middle of the summer – and I totally get that. But we make and eat soups all year long – especially when they are as delicious as this Zucchini Tomato Italian Sausage Soup.

In fact, we love the convenience of cooking up a big pot of this soup, then reheating leftovers in the microwave for a light, quick meal.
How do you make Zucchini Tomato Italian Sausage Soup?
Most of the prep in this Zucchini Tomato Italian Sausage Soup is chopping and dicing and grating – garden zucchini, tomatoes, onions, celery, red bell peppers, garlic, and carrots, plus fresh basil and oregano, and Parmesan cheese.
After browning some sweet Italian sausage and sautéing the onions, celery and bell pepper in a pot, you’ll add all of the other ingredients including vegetable stock to the pot. Then, a ten to fifteen minute simmer on the stove finishes off this flavorful Zucchini Tomato Italian Sausage Soup – just long enough so that the zucchini and other vegetables are tender and the flavors meld.

Can I add other vegetables in this soup?
Absolutely! We created this Zucchini Tomato Italian Sausage Soup to use up fresh zucchini, tomatoes and some of the fresh herbs from our garden – but you can also add other fresh vegetables and herbs if that is what you have growing in your garden.
You can also add pre-cooked pasta to this soup if you’d like. And, if you like things extra zesty, feel free to swap in hot Italian sausage instead of the sweet.

Can I make this Zucchini Tomato Italian Sausage Soup in the slow cooker?
From the questions we often get, I know that a lot of our readers like to use their slow cooker during the summer to avoid heating up the kitchen! (So, I’m anticipating being asked this question!) 🙂
We haven’t tried making this recipe in the slow cooker ourselves – mostly because it only takes about thirty minutes (or less) to cook this soup on the stove. While a slow cooker will sort of technically work, you’ll still want to brown the sausage before adding it to the slow cooker, which is half of the cooking time listed in this recipe. Additionally, the zucchini may end up over-cooked before the rest of the vegetables are tender. So, while it’s possible, we’d still recommend cooking this Zucchini Tomato Italian Sausage Soup recipe as written because it will take less time and the results will be better.
If you want to save some time when you are rushing to get dinner on the table, feel free to chop all of the vegetables ahead of time.

Zucchini Tomato Italian Sausage Soup
This Zucchini Tomato Italian Sausage Soup is a delicious way to use up all of those fresh garden vegetables!
Ingredients
1 tablespoon extra-virgin olive oil
1 pound Italian sweet sausage, removed from casings
2 cups onion, diced
1 cup celery, diced
1 cup carrots, diced
2 cups red bell pepper, diced (about one large pepper)
2 tablespoons fresh garlic, minced
Pinch red pepper flakes
1/4 cup tomato paste
5 fresh plum tomatoes, diced
2 pounds zucchini cut into bite-sized pieces
1 teaspoon kosher salt
1/2 teaspoon freshly ground black pepper
2 quarts good quality vegetable broth
1 cup coarsely grated Parmesan cheese, plus more for serving
A few Parmesan cheese rinds (optional but recommended)
2 tablespoons fresh basil chopped
1 tablespoon fresh oregano chopped
Instructions
- In a large soup pot or large Dutch oven, place olive oil over medium high heat and once hot, add sausage meat. Break up meat while it cooks.
- Once the meat has browned, add onion, celery, carrots and bell pepper and sauté for four minutes.
- Move the vegetables to the sides and lower heat to medium. Add garlic, pepper flakes and tomato paste to center and cook for two minutes, stirring occasionally. Add tomatoes, zucchini, salt, pepper, broth, Parmesan cheese and Parmesan rinds along with fresh basil and fresh oregano and stir to combine.
- Bring to a medium simmer and cook just long enough until the vegetables are tender, about 10-15 minutes. Once the zucchini is added to the pot, try to avoid overcooking. The squash should be just tender.
- Remove from heat and remove and discard the Parmesan rinds.
- Serve immediately with additional Parmesan cheese on the side.

Thanks Blain – great suggestion!
Absolutely delicious! Will definitely make again for friends and family!
Thanks Andrea – glad you enjoyed it!
Made this soup today, it was one of the most delicious soups i’ve ever made.
Wow Bernadette – so glad you enjoyed the soup!
This recipe is a keeper! Making it for a second time already. I did add small macaroni to it.
Thank you. Love your recipes.
Thank you Susan – so glad you are enjoying the recipes! 🙂
This is the best soup !!! Everything about it. I cut the recipe in half as it is just me and my husband. Love the fact that all of the vegetables are fresh. Will definitely make again !
Thanks Helen!
This was excellent! We’re trying to get more vegetables into our diet and this was a great w ay to do it. Because I love tomatoes, I added a large can of Marzano tomatoes, which I broke up with my hand. I’m so glad I did because I found my husband feasting on it twice during the day. He thought the addition of turkey Italian sausage did the trick.
So glad you both enjoyed the recipe Patricia!
Hi Martha, Do you have the nutritional vale for this yummy soup?
Hi Suzanne – I’ve just added the information to the bottom of the recipe card.
I’ve made this dish several times now, it’s delicious! Everyone I’ve made it for loves it, and it makes me look like an awesome cook (really I just follow directions well lol!) I served this soup at a get together with neighbors, and one of the women said she wasn’t leaving until I shared the recipe with her. Make it – you won’t be sorry!!
Thank you Kim! So glad the recipe is a hit!
AWESOME Soup!!!! Love it. The recipe is too much for the two of us. Can I freeze this? Thank you!
Hi Cathy – The zucchini might get a little soft after being frozen and thawed, but if that doesn’t bother you, yes it can be frozen.
