This light and creamy chilled zucchini basil soup is perfect for warm weather meals.

Gaspacho or even cucumber soup is probably what first comes to mind when you think of chilled soups, and while tomatoes and cucumbers make for excellent warm weather soups, I’m also quite fond of those featuring another summer staple: zucchini.
Puréed until silky smooth the mild mannered squash makes a light and creamy soup that’s nice and refreshing when served chilled.

A cold soup like this zucchini basil soup is always a great one to have on rotation this time of year. Smooth and satisfying, it’s the perfect appetizer, first course or even main attraction depending on your mood or need.
What's in zucchini basil soup?
There's zucchini of course that's quickly sautéed with garlic and celery.
Then I add pumpkin and hemps seeds which makes the soup creamy without using any cream and adds a nice nutty flavor.
Basil and lemon zest keep things bright and lively, while olive oil adds a pleasant silkiness when everything is all blitzed up together.

The amounts I’ve called for make about 2 servings but it could easily be one if you’re eating it as a meal by itself. It’s also rather quick to prepare, which is always a plus, and most of the heavy lifting is done in the blender. You can make it ahead of time and let it sit in the fridge until you’re ready or chill it down quickly in an ice bath if you’re in a real hurry.
