This easy zucchini soup requires just a few pantry staples and under 30 minutes to make. Basic cream of zucchini soup that could be topped with cheese, sour cream , parsley or croutons.

What ingredients do I need to make this zucchini soup recipe?

Zucchini – zucchini variety of your choice. For soup, you can use any type of zucchini. Either dark green, light green or striped. No need to peel the vegetable. Just trim the ends and cut into pieces. Cook until soft, then puree until smooth.

Olive oil – any type of vegetable oil can be used. Butter can be substituted. Use it to cook the garlic and onion until soft and fragrant.

Cream – omit for the vegan version or use a plant based substitute. If you want to make a truly creamy, smooth and tasty soup I suggest that you use heavy whipping cream. Sour cream can be used instead and it produces less creamy cream of zucchini soup.

Salt, black pepper, thyme – salt and black pepper are mandatory to season the zucchini and bring some taste to the soup. Thyme is optional, but it brings a nice, distinct flavor to the soup. Basil can be used instead of thyme.

Bone broth – perfect for Keto and low carb. Stay tuned for my homemade bone broth recipe. Chicken or vegetable stock can be used instead, to make the soup taste more balanced. Water and some chicken or veggie bullion can be used as well.

Green herbs, sour cream or olive oil – for garnishing.

What type of zucchini should I use?

Any type of zucchini in any size work in this recipe.

How to thicken the soup, if necessary?

If your soup is too thin, you can simmer it uncovered for a few minutes to reduce the liquid, add more cooked zucchini or potatoes, or blend in a small amount of a slurry of cornstarch (or all-purpose flour) and water. 

My soup is lacking flavor, how can I improve it?

You can add different herbs like thyme, basil, parsley or dill.
A squeeze of lemon juice, a little bit of nutmeg, or a bit of Parmesan cheese (not vegan) at the end can also brighten the flavor.
Using good-quality vegetable or chicken broth will make the soup more-flavorful, too.

Can I make the soup without dairy?

Yes, there is no need to use dairy products in the recipe. 
Use coconut milk, almond milk, or cashew cream instead of dairy cream.
Another option is to blend in some cooked potatoes or cauliflower to make the soup creamy.

What should I serve this soup with?

Serve the soup with crusty bread or a salad. A topping of croutons, roasted chickpeas, or a drizzle of olive oil, a sprinkle of grated Parmesan cheese or hot pepper flakes.

  1. Several creamy zucchini soup recipes out there, but this is a good one. I used it as a guide to salvage a much less flavorful version. Tip: Try adding a few dashes of Tabasco sauce; it’s my secret ingredient in cream soups and white sauces. Hubby loved the results.

  2. I made this soup tonight. It was really, really good. I’d never had zucchini soup before and didn’t know what to expect but it is definitely worth making. I made the recipe exactly as it’s written and personally wouldn’t make any changes to it. Best of all, it was so easy to make! Thank you for sharing such a great recipe.

  3. It’s simmering right now. I did one and half times all ingredients and eyeballed everything except the broth. I subbed seasoned veggie Better Than Boullion and light sour cream. I also only used about 2.5-3 T of Kerrygold butter when I sautéed the veggies in a large iron skillet. I transferred the mix to a stock pot and then added the broth. Serving with crusty bubble bread from Pargo’s. Google it, you won’t be disappointed. 

  4. Was looking for a quick supper that didn’t require any last minute trips to the grocery store and this recipe fit the bill. After reading a few reviews, I also chose to add a little heat with some pepper flakes in the first step with the melted butter/oil. It was a delicious summertime light meal with plenty of possibilities to alter the base recipe to your liking. I will be making it again.
