Creamy Zucchini, Walnut and Dill Soup

4.5 stars based on 9 votes

May marks the start of zucchini season but I love this silky puréed soup anytime of year. It’s surprisingly healthy — there’s no heavy cream or dairy in it, just a handful of toasted walnuts to thicken it up.


Begin by heating the olive oil in a large sauté pan, then add the chopped onions and garlic.


Cook over medium-low heat until the onions are soft and translucent.


Add the sliced zucchini, chicken broth, salt and pepper to the pot.


Bring the soup to a boil, then cover and simmer for about ten minutes, or until the zucchini is tender.


Meanwhile, toast the walnuts in a 350 degree oven for 5-10 minutes, until fragrant.


When the soup is cooked, add the toasted walnuts and chopped dill to the pot.


Purée the soup in batches in a blender. (I prefer a blender over a hand-held immersion blender for this recipe because it’s more powerful and does a better job blending the nuts into the soup.)


Pour the puréed soup into a bowl as you go.


Rinse the pot, pour the soup back in, and stir in the fresh lemon juice. Taste and adjust the seasoning to your liking.


Ladle the soup into bowls and garnish with more dill if desired. Enjoy!


Note: This soup can be served hot in the cooler months and cold in the summer.

Creamy Zucchini, Walnut and Dill Soup

Servings: 4
Total Time: 20 Minutes


  • 2 tablespoons extra virgin olive oil
  • 1 medium yellow onion, chopped
  • 2 garlic cloves, cut into quarters
  • 4 medium zucchini, halved lengthwise and thinly sliced
  • 4 cups low sodium chicken broth (such as Swanson Organic)
  • 1 teaspoon salt
  • 1/4 teaspoon freshly ground black pepper
  • 2 tablespoons fresh dill, or 1 tablespoon dried, plus extra for garnish
  • 1/2 cup walnuts, toasted
  • 1 tablespoon freshly squeezed lemon juice, or to taste


  1. Preheat the oven to 350 degrees. Line a baking sheet with aluminum foil.
  2. Heat the oil over medium-low heat in a large pot. Add the onion and garlic, and cook for about 5 minutes until onions are soft and translucent. Do not brown.
  3. Add the zucchini, chicken broth, salt and pepper, and bring to a boil. Turn heat down to low, cover and simmer for about 10 minutes, or until zucchini is tender.
  4. Meanwhile, place the walnuts on the prepared baking sheet and toast in the oven until fragrant, 5-10 minutes. (Keep a close eye on it as nuts can burn quickly.)
  5. Add the dill and walnuts. Working in batches, process the soup in a blender until smooth. (Be careful not to fill the jar more than halfway, and leave the hole in the lid open and loosely cover with a dish towel to allow the heat to escape.) Pour the puréed soup into a large bowl.
  6. Rinse the pot, pour the soup back in and bring to a gentle simmer. Add the lemon juice, then taste and adjust seasoning with salt, pepper or more lemon juice if necessary. Serve hot immediately or chill and serve cold.

Reviews & Comments

  • Hi Jenn!
    Thanks so much for your amazing recipes-2018 seems so far away:-)
    Was hoping to make this soup and wanted to know if I can substitute the fresh dill with ground dill? I have seeds I can grind but no access to fresh dill. Also: are the walnuts a complete must? Can I leave them out and not alter the recipe? Thanks!

    • Glad you like the recipes, Sarah! Yes, you can use dried dill here; you’ll just need 1 Tbsp. plus more for garnish. And if you’d prefer not to use the walnuts, you can thicken the soup with cream. Hope you enjoy!

        Thanks Jenn. I did just that: talk about transforming zucchini!!! The Dill really does something to the soup. I’ll try and get my hands on walnuts the next time I’m able to: I can only imagine just how muxh more awesome the soup will be! A keeper 🙂

    I have to admit, when I saw zucchini soup I was scepticle but omg this totally blew me away! It’s super creamy without the cream and the dill gives it such a unique and delicious flavor! I haven’t been disappointed yet with any of your recipes! Thank you for sharing.

  • A family favourite that has been passed along to many others, so delicious, a definite fan of this flavourful soup.

    This was a delicious soup…. until I added the dill. My guests just didn’t go for that taste in a soup. So next time I’ll just leave that out because the rest was fantastic – especially the toasted walnuts.

    This soup was a disappointment. The only flavor came form the dill; the nuts – although I blended like a demon – did not totally blend into the soup, gave no flavor, just an unwelcome crunch. I see no room for improvement here. Moving on.

  • Hi Jenn, I find it a bit hard to determine medium zucchini as I have seen really large ones and really small ones. Do you have an approximate number of cups of sliced zucchini so I can make sure mine are the right size? I am very excited to try this recipe!

    - Jeanette on September 9, 2016 Reply
    • Hi Jeanette, 1 medium zucchini should yield about 1 – 1/4 cups of sliced zucchini, so for this recipe, you’d want 4 – 5 cups sliced zucchini. Hope you enjoy!

    Pleasantly surprised by how easy and delicious this recipe was. Calorie counter, as I am, this was a perfect choice. I didn’t miss the cream I would have added normally for the rich finish. The dill flavor was more pronounced when I served it chilled. Yum!
    Hot or cold, this recipe is worth 5 stars.

    I have made this recipe 3 times now. I made a double batch for the first course of our Thanksgiving meal. I can’t wit to introduce it to my family! For a double batch I toasted one cup of walnuts and blended it with the soup and ground a second cup in the food processor and mixed it in afterward. I also use a whole lemon, zest and all. It’s the BEST!

  • Could this be used with yellow squash instead??

    • Hi Jordan, Yes definitely 🙂

  • I am planning on trying this recipe as I planted zucchini this summer which is coming in now however any suggestions on replacing or eliminating the walnuts, I have someone in my house that is allergic to nuts…..thank you!

    • Hi Lila, You can thicken the soup with cream. Enjoy 🙂

    This is so good. I added a bit more toasted walnuts 3/4 a cup. I pulsed the first batch in the vita mix so the soup would still have some texture, the rest I pureed. I have served this hot and at room temp either way it is amazing. Fresh Lemon is the key to really bringing the flavors out so I added quite a bit. Also for a finishing touch I sprinkled the soup just before serving with fresh graded Parmesan cheese. Unbelievably good. I had to share this. 🙂

  • Hello 🙂 Could I substitute the chicken broth with vegetable broth? Thanks =)

    Quick, easy, delicious week-night meal. I thought I might want to add some cream or cheese, but it didn’t need it. The toasted walnuts added made it creamy and gave the soup body. We tried it hot tonight; can’t wait to try it cool for lunch tomorrow.

  • I learned something new with this soup. I thought creamy always meant using heavy cream and as someone who is lactose intolerant I was very happy to find something creamy and lactose free! I thought walnut and dill in soup was weird but this recipe changed my mind forever. Officially one of my most favorite go to soups now!

  • This soup tasted flat. The lemon juice gave it much needed acidity, but the flavor profile was dull and one dimensional. I made a double batch in my excitement, and now I am stuck with unfinished soup. I tried adding more dill to liven it up, but alas. The only good thing is that it is healthy.

  • I am swamped with summer squash- has anyone tried this yellow squash??

  • your soups are excellent! Can I freeze the Creamy Zucchini, Walnut and Dill Soup after I add the lemon juice???? Made a double batch!

    • Hi Elaine, Thank you! Yes, it is fine to freeze the soup.
