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!
Tools For This Recipe

- 4-Quart Dutch Oven– This is the perfect size for this soup. This one is high quality and you’ll have it forever. (I use one almost every time I cook!)
- Spice Rack– This is the one I have, it’s a snap to measure out your seasonings quickly and easily. (Big time saver.)
- Measuring Spoons– To measure out the seasonings.
- Pinch Bowls– I measure out my seasonings ahead of time and add them to these small bowls so they’re ready to go when it’s time to add them.
- Immersion Blender– To blend this right in the soup pot without transferring to a blender.
- Box cheese grater – I always shred cheese from a block in my recipes. It melts and tastes better than packaged shredded cheese.

Zucchini Soup
Ingredients
- 2 tablespoons butter
- 1 yellow onion, diced
- 2 cloves garlic, minced
- ¼ teaspoon EACH: dried rosemary, thyme, celery salt, pepper, 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, shredded
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 the onions and cook until softened, about 5 minutes. Add garlic, zucchini, and seasonings. Cook for 5 minutes, stirring occasionally.
- Peel and rinse the potatoes. Cut them into small pieces of equal size so that they cook evenly and quickly.
- Add the potatoes, chicken broth, and soy sauce. Bring to a boil, then reduce heat to a simmer. Skim up any brown foam from the top if needed.
- 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 and 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.

So delicious. I added a bit of curry powder since I used sharp cheddar. It was truly enjoyed & will be made again!
Yummmm! Nice work Therese, sounds delicious! Thanks so much for taking the time to leave a review!💖
Hi! Great recipe ,making it today for the second time !
I had some carrots that were on their way out so I grated and added to the soup. 🙂
What is your favourite way to freeze ?
in bowls , bags? Any tips?
Thanks!
I’m so happy that you loved the soup, I just had some of this from the freezer last night, I like adding carrots too! 🙂 I freeze them in 16 oz. storage containers! They have 8 oz. sizes as well. They’re stackable, leak proof, and dishwasher/microwave safe.
Ramekins are good to freeze in. Restaurant stores have plenty of options on sizes. The 5.5 oz is my favorite. It works well for meals, snacks or for jazzing up other things—like rice.
The recipe was easy and fast to make and smooth and thick. I scrimped on herbs and I peeled the zucchini so I didn’t get that nice green color and I was hoping for more flavor. I shredded cheddar but I still want to add some other herbs
WOOO! I’m so glad that you loved it Ellen!! You can definitely add lots of different herbs to this, I’m sure you’ll have fun playing with the flavors. Thank you so much for the review! ❤️
Love this recipe, it’s one of our family favourites. I passed it onto other friends too and they love it.
AWESOME! I’m soo happy to hear that Lillian!! Thank you so much for passing the recipe along!! 🙂
Hi Stephanie,
This soup recipe of yours was fabulous. There were a lot of doubters up until eating time – then I had a lot of converts! Making another big batch today for the family.
Cheers
John
Ohhhh that is the best news ever!! I can understand doubting the amazingness of this soup, LOL. I’m glad you have converted people! Thank you so much for the review, it made my day! 🙂 -Stephanie
I made this today on a rainy day in Georgia. It was absolutely delicious! Seasonings are perfect and I used Worcestershire rather than soy. I like chunky soups so I didn’t puree it all the way. Highly recommend!
I am soooo happy that this did the trick for you on a rainy day Nancy!! Thank you so much for taking the time to leave a review, I really appreciate it! 🙂 I probably have 20 portions of this in my freezer right now, I LOVEEE it 🙂
