The Best Creamy Zucchini Soup

Oh, I wish it were zucchini season all year round!

If you've had a good look around my blog, you will have noticed that there are quite a few recipes featuring this ingredient [yes, and many chicken curries too... life is about balance!], and that is because there are so many ways it can be used [and because in Italy we practically live on it throughout summer].

This comforting soup is perfect for lunch or dinner, and it can be served as a light starter, topped with some red pepper flakes or fresh dill, or as a main course with a nice warm slice of crusty bread topped with a dollop of garlic butter.

Now, if you have 30 minutes, four zucchini, and an immersion blender, it is definitely the time to try this absolutely delicious Italian soup.

Next on the list, you must try this Roasted Cauliflower Soup!

Ingredients Zucchini Soup

• Zucchini: Fresh, young zucchini are best. Choose firm ones with shiny, non-wrinkly skin - these will taste best. I have answered the most important FAQs on zucchini in this Grilled Zucchini and Ricotta Recipe.
• Oil, Shallots, Garlic: The base of most soups. Olive oil can be swapped for a flavorless one, such as sunflower or vegetable oil, and shallots for any color of onions, while garlic is irreplaceable [but may be skipped if not liked].
• Vegetable Stock Cube: Or powder, as available.
• Cashew Nuts: These will give the creaminess and thick consistency to the soup. Zucchini is a very watery vegetable, so these thicken the soup without the need to add potatoes.
• Lemon Juice, Parsley, and Tarragon: This combination of flavors work well to keep this soup fresh while still being thick and creamy.

How To Make Zucchini Soup?

1. In a large saucepan add the oil and warm it up on medium heat; once warm, add the thinly sliced shallots and cloves of garlic, together with a pinch of salt, mix well and cook until the onion and garlic turn light golden brown.
2. Next, add the chopped zucchini and sauté for a couple of minutes before adding a stock cube, cashew nuts, salt, and pepper and mix well; add enough cups of water to cover the vegetables in the large pot. Bring to a boil, then simmer the soup on medium-low heat for 15-20 minutes or until the vegetables are soft.

3. Before blending, add some characteristic Italian seasoning, such as parsley and tarragon, and a squeeze of lemon juice for its vibrant flavor, then allow it to simmer for a couple more minutes on medium-high heat.
4. To obtain a pureed soup, allow it to lightly cool down before adding it to a food processor or blending it with an immersion blender. Serve and enjoy!

How to store creamy zucchini soup?

• In the fridge: You can store leftover zucchini soup in an airtight container for up to three days.
• In the freezer: You can freeze zucchini soup for up to three months.

Ingredients Top Tips:

• Fresh zucchini: always ensure you use zucchini that are fresh, as acidic zucchini can be harmful. Check that the summer squash is nice and firm, the skin bright and not wrinkly.
• Shallots: should you not have or like shallots, you can use onions instead; brown, white, or red onions will all work well.
• Fresh herbs: while I used dry parsley and tarragon for this recipe, should you have fresh herbs then use those instead. Feel free to add fresh basil, thyme, or a mixture of fresh herbs.

Tips and Tricks for Creamy Zucchini Soup

• Thickness: This Italian zucchini soup uses cashew nuts to obtain a nice creamy consistency once blended, as zucchini per se are quite watery vegetables. Should you need to swap this ingredient, then you can substitute it with half a cup of coconut milk, as this will offer it a nice creaminess. If you are not following a vegan diet, then adding some parmesan cheese, a dollop of sour cream, full fat plain natural yogurt, or heavy whipping cream when serving is also a great way of increasing its thickness; if you are going for either of these options ensure not to add too much, as zucchini are quite a delicate tasting vegetable and they would be overpowered.
• More Veggies: This soup tastes great as it is or with more vegetables in it. Great additions are celery, carrots, bell peppers [green peppers give a nice contrast], baby spinach, or potatoes. If going for beans [such as cannellini beans, white beans, or kidney beans], do not add the cashews, as these will thicken the soup once blended.
• Stock: if you do not use stock cubes, you can use a couple of cups vegetable broth or chicken broth instead (if you are not following a vegan diet). I would suggest going for traditional stock flavors rather than special versions (ie: added lemon or herbs) or beef stock, as these may overpower the taste of zucchini. If you have some homemade chicken broth, that is a good choice too.
• Spice it up: if you like your soup to have a bit of heat, then you can skip the Italian herbs and add some curry powder or cayenne pepper instead; add a quarter teaspoon once the onions are cooked and stir fry for 30 seconds before going on to the next step. Add one or two bay leaves when you add the water or broth, but remember to remove them before blending this easy soup. Lastly, serve the soup hot with a few red chili flakes for the ultimate hearty soup with a kick!
• Dutch oven: this great recipe can also be prepared in a Dutch oven and it is a great choice, as the thick bottom of these pans helps the heat spread in a more even way, all while holding the heat for longer.
• Serve it cold: looking for an easy way of serving a great summer lunch? There's no need to serve this soup hot, as cold it is as nice! Just serve it with a little lemon zest or juice for that extra zing, or season with some celery salt when preparing it.

This easy recipe is no doubt the best zucchini soup recipe, as it is tasty, ready in half an hour, and versatile... the ultimate comfort food! No more looking for soup recipes, or dinner recipes, this covers you for both.

Eat it with a slice of warm crusty bread, top it with a splash of cream or add an extra touch of lemon... it will always be glorious!
