This healthy and hearty zucchini soup recipe is the BEST way to use up fresh garden zucchini! The broth is perfectly seasoned with herbs, spices, and potatoes that are blended in to thicken it with no need for additional cream or cheese. (But feel free to add some for extra indulgence!)

Zucchini Soup
This is the first recipe in history, in all of my years of recipe development, where I emailed my mom and best friend to make this right away- before it was even up on the blog. When I say that this is the best zucchini soup recipe, I am not kidding.
(It definitely made the cut for The Cozy Cookbook!)
The best part is that there is no need to add any cream to it if you want to keep things lighter. It tastes perfectly good without it! (Of course, being The Cozy Cook and all, I add just a little bit.)
The cheese options are endless, I went with a sharp orange cheddar. White cheddar, Parmesan cheese, or even Gouda cheese would be excellent additions to this soup.
How to Make it
Note: This is an overview. See recipe card below this post for ingredient quantities and full instructions.
Cook diced onion and garlic in melted butter until softened. Add zucchini and seasonings, sauté for 5 minutes. Add chicken broth, soy sauce, and diced potatoes.
Bring to a boil and reduce to a simmer, cook for 20 minutes, until vegetables are very soft.
Use an immersion blender or regular blender to blend until smooth. Serve, or add cream or half and half if desired.
Shredded cheese may also be added. Options include Cheddar, Parmesan, and Gouda. Stir until combined and smooth. Serve!
Do You Peel Zucchini for Soup
If you are working with a very large zucchini, you may choose to peel it first as sometimes the skins can become tough and bitter if they’re overly large. Otherwise, no need to peel.
The ideal size for a zucchini is about 6 inches, this is when it’s at it’s most ripe.
How Do You Thicken Zucchini Soup
This zucchini soup recipe doesn’t require a roux or slurry in order to thicken it. Instead, potatoes are added to the soup and are blended into the broth until smooth and creamy. This makes the broth nice and thick without the need to add anything extra.
PRO TIP: I love the convenience of using my immersion blender to blend this soup, (you can get one on Amazon here), however others have had success using a potato masher as well! It will have a little more texture, but some prefer it that way.
Storage
- Store in an airtight container and refrigerate for up to 3 days or in the freeze for up to 3 months. This soup freezes/reheats super well!
Health Benefits of Zucchini
As reported by Healthline, zucchini is rich in nutrients, high in antioxidants, aids in digestion, can improve heart health and reduce blood sugar levels and more. So feel good about eating this soup!

Zucchini Soup
Ingredients
- 2 Tablespoons butter
- 1 small yellow onion, diced
- 2 cloves garlic, minced
- ¼ teaspoon dried rosemary
- ¼ teaspoon dried thyme
- ¼ teaspoon celery salt
- ¼ teaspoon black pepper
- ¼ teaspoon kosher salt
- 1 pinch cayenne, optional
- 5 cups zucchini, cut into chunks
- 3 cups chicken broth
- 1 Tablespoon soy sauce, (or Worcestershire sauce)
- 2 Russet potatoes, equal to 1 pound
- 1/2 cup Half and Half, or heavy cream
- 1 cup Cheddar Cheese
Instructions
- Note: There is no need to peel the zucchini for this soup unless yours is jumbo sized, in which case it's possible that the skins are tough and slightly bitter.
- Shred the cheese from a block for best results. Set aside to allow to come down to room temperature. This will allow it to melt and combine into the soup smoothly.
- Melt butter in a soup pot over medium heat. Add onions, cook until softened, about 5 minutes. Add garlic and cook 1 more minute.
- Add diced zucchini and seasonings: (1/4 tsp each of: dried rosemary, thyme, celery salt, kosher salt, pepper, and an optional pinch of cayenne.) Sauté for 5 minutes.
- Peel and rinse the potatoes. Cut them into small pieces of equal size so that they cook evenly and quickly.
- Add diced potatoes, chicken broth, and soy sauce. Bring to a boil, then reduce heat to medium. Skim up any brown foam from the top if needed.
- Let simmer, partially covered, until the vegetables are very fork tender. About 20 minutes.
- Remove from heat. Use an immersion blender or transfer to a blender in batches to blend until smooth.
Optional:
- Transfer back to the heat on low. Stir in the half and half.
- Slowly sprinkle in the cheese and stir to combine. Remove from heat and serve!
Notes
- The dairy is optional, this soup tastes great without it. If adding cheese, feel free to experiment with different varieties such as Sharp White Cheddar, Parmesan, Gouda, or a combination of different cheeses.
- The addition of soy sauce adds umami and enhances the other flavors in the soup, you won't be able to taste it, but it's a great cooking tool.
- You can get an immersion blender on Amazon, it makes it easy to blend soups and sauces right in the pot without having to transfer it elsewhere and blend in batches.

I’m making my 3rd batch this summer. Some I eat, some I give away and some is frozen. It’s delicious, didn’t change a thing on your recipe. Everyone loved it.
That’s great news Leslie, really nice of you to give some away to people too, soup is the best gift you could give I do believe! 😉 I too have made 3 batches this summer and am gearing up to make a 4th before the season ends! 🙂
This soup is delicious! Knowing how well lemon complements zucchini, I substituted lemon pepper for the regular pepper and increased the salt and lemon pepper to taste. I used sharp white cheddar for the cheese and I did add the half and half. It was not only delicious, but also a great way to use a huge zucchini I got from a friend’s garden. I just cut out the center section of the zucchini with the mealy texture and large seeds when I chopped it up and the soup turned out fantastic in every way. Will definitely make this recipe again!
I’m so happy you enjoyed this Melissa! I love your idea of using the lemon pepper😋! Such a great way to use those giant Zucchinis. Thanks so much for taking the time to leave a review!
Made it and the whole family loved it!
If I were to pause the recipe after adding the cubed potato, do you think i could pressure can it for quick winter meals? Just warm up, blend and add the dairy later? I have so much zucchini now, it would be so nice to save some for later.
Hi Heidi! I always freeze this soup so that I can enjoy it throughout the winter, but I haven’t canned it. I agree that eliminating the dairy would be a good step to take for canning but unfortunately I’m not experienced enough to offer any guidance. If freezing is an option, then you wouldn’t have to eliminate the dairy, it freezes and reheats really well with it!
Wow! great soup. Easy to make and delicious. I did not add the cream because I found it creamy enough without it from the potato I think.
Thanks.
Happy to hear you enjoyed the soup Curt! It’s one of my favorites😍. I love how creamy it is! Thanks so much for taking the time to leave a review!
Just made this and it’s so delicious!! I’m so happy with how good it was!!
Soooo happy to hear that Janelle, thank you so much!! -Stephanie
Can you freeze zucchini soup
YES it freezes really well!!
My husband tore this soup up! I had to use 1/2 veggie broth bc I ran out of ckn broth and added a chicken cube.
I’m so happy to hear that! This is one of my favorite soups. Thanks so much for taking the time to leave a review!😍
I made this tonight for dinner. I puréed everything but potatoes. Delicious!!!!!
I’m so happy that you enjoyed it D.M.- thank you so much for the review!! -Stephanie
Delicious soup! Excellent!! It’s hot and humid out but who cares….soup is an anytime food! My family doesn’t love soup in the summer, so that means more for me 😀. I didn’t have potatoes so used cauliflower and added another cup of water….it was sooo good! I highly recommend.
I am so happy to hear that Gail, thank you so much for sharing your thoughts on this! I just made another batch of this last weekend, I’ve made 3 batches so far this season, (and counting!)- I love having it for the freezer! Thanks again, you’re the best! -Stephanie
Very well might be the best soup I’ve ever had. Fantastic taste and perfect texture. Serve it hot or room temperature, it’s great either way.
I’m so happy to hear that! I’m so obsessed with this soup so I love hearing from people who are loving it too! Thanks so much for taking the time to leave a review!❤️
