Zucchini Soup

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.


  • 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

(Amazon affiliate links)- Check out all of my kitchen essentials here.

  • 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.
  • Garlic Twister it’s much more flavorful to mince fresh garlic. This twister does it in seconds and is easy to clean and store.
  • Soup Bowls(I love these!)
  • 16 oz. storage containers – I use these to store/freeze my soups. They have 8 oz. sizes as well. They’re stackable, leak proof, and dishwasher/microwave safe.

This creamy zucchini soup is the BEST way to use up garden zucchini with no need for a roux to make it nice and thick! Simply blend seasoned zucchini with potatoes to create a thick and flavorful broth. Add a touch of cream and your choice of cheese if desired for even more indulgence!


  • 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


  • 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.


  • 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!


Pro Tips:
  • 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.

  1. This is a keeper ♥️ and all three of that had it with our lunch think so❣️
    winner 👍

  2. This was easy, quick and amazingly delicious!!
    I used sweet potato and a small carrot in place of the potato, as it was what i had on hand. I will make this again!

  3. I have a couple of yellow squash… can I add these to the zucchini in this recipe or will it mess it up? 

  4. We really enjoy your soup making it exactly to the recipe. I have made it lots of times to use up the multitude of zucchini that we grow. Great flavour 

    • I’m so happy you enjoyed it Helen! It’s actually one of my favorite soups, you can’t beat it with garden fresh zucchini! Thanks so much for taking the time to leave a review!💖

  5. This is an amazing recipe! My husband and I really enjoyed the soup. I was a bit wary after I added the soy sauce but it gave the soup a more complex flavour. I used some Emmentaler I had on hand and it was amazing!

  6. This soup is so good and filling. I have made it several times. Didn’t change a thing. Thanks for sharing.

  7. Can you use fresh diced sautéed celery instead of celery salt, i don’t have any to my surprise!!!

  8. How many med. zucchini is 5 cups? Or the weight ?

  9. My family loves this soup I make big batches and freeze them when I don’t feel like cooking I take it out the night before and leave it to defrost in the fridge and than warm it up and add the cheese than and it’s like I was cooking all day. The only thing I changed was instead of celery salt. I add celery instead and my brother who doesn’t like celery has no idea he’s eating it. This is an incredible soup. 

    • I’m so happy that you love the soup Maggie! I love freezing this too, I always have it in my freezer 🙂 LOVE that you add real celery to it and that your brother doesn’t even know!

  10. This has become my most favorite soup!!! Just can’t get enough of it. Thank you for sharing!!!
