This soup is so delicious… and easy! I can’t cook well, so I rely on my slow cooker for a lot of recipes and meals. This is good enough to serve to guests, and it’s nutritious. Even my husband (who doesn’t like zucchini and squash) agrees that this one is a winner.

If you’re looking for a unique way to squeeze in the veggies, this recipe will help you do it. It’s absolutely delicious! Thanks to the ground sausage, chicken broth, and seasonings, the vegetables won’t stand out so much. This soup with zucchini is a healthy take that uses a dump-and-go method once you’ve cooked the sausage and diced the vegetables.
The quick prep time and moderate cooking time makes it an ideal option for busy weekdays or weekends. It’s also prep-friendly, meaning you can prepare everything a day or 2 before you actually want to cook it. Hope you enjoy it!
Key Ingredients
- Ground Sausage: I recommend using Jimmy Dean brand; however, you can use whatever you prefer. (we also use this sausage in our slow cooker sausage dip, or slow cooker sausage lentil soup).
- Vegetables: Diced carrots, celery, yellow onion, sliced yellow squash and zucchini along with a can of fire roasted tomatoes.
- Seasonings: Minced garlic, salt, black pepper, balsamic vinegar, and Italian seasoning.
- Chicken Broth: Helps create the delicious soup base. You can also use vegetable broth or vegetable stock.
- Tomato Paste: Used to create a tomato flavor.
How to Make Zucchini Soup
Step One – Cook and crumble the ground sausage on the stove top. Drain off excess fat if desired.
Step Two – Add the sausage to the slow cooker, along with the remaining ingredients (except the zucchini and squash).
Step Three – Cook on LOW for 6 hours.
Step Four – When the cooking time is up add the zucchini and squash.
Step Five – Cook for an additional 45 minutes on LOW or HIGH. Serve and enjoy!
How to Serve
- This soup is perfectly served as is. Add a bit more salt and pepper to taste. A generous grating of parmesan tastes great as well.
- You can also pair it with a piece of your favorite crusty bread.
- If you want it a bit spicy, top it with a dash of red pepper flakes, hot sauce, or sliced jalapenos.
Recipe FAQs
If you want a vegetarian version, simply leave out the sausage (and use vegetable broth instead of chicken broth). You can also use meatless crumbles if you want a meat-like look and taste.
You can add whatever you like. Green bell pepper, red peppers, mushrooms, and corn make great additions. Cannellini beans and fresh tomatoes would taste great as well.
Place any remaining soup in an airtight container and store in the fridge for up to 4 days. Reheat on the stovetop until warmed throughout. Freeze this soup in a freezer safe container for up to 3 months. Allow it to defrost overnight before warming it up.

Yay! This is a fun recipe that I wish more would try!
My lady friend wasn’t sure she’d like it as she doesn’t normally like summer squashes but I cut the recipe in half as she only needed some for a couple days. Since fire-roasted tomatoes don’t come in a nice convenient 8-oz. size for half recipes I just used an 8-oz. can of tomato sauce she had on hand. I also threw in a 15-oz. can of cannellini beans (minus the liquid) to bolster the protein and fiber and still used the full amounts of the squashes and she liked it. She suggested the addition of a little liquid smoke next time if I’m not using fire-roasted tomatoes (which I think she also has on hand as I sometimes make her your Dr. Pepper ribs recipe which her mom also had as I made them for her once while her mom was also visiting and her mom says those were the best ribs she ever had LOL). Oh and I also used hot Italian pork sausage from the meat counter at one of the local supermarkets instead of Jimmy Dean’s (I just squeezed the ground meat out of the casing and browned it).
This was good ! Had it with some crust bread and butter
I loveeeeeee it!!!! Thanks tha
