Cucumber Soup Recipe Ingredients

Here’s what you’ll need to make this cucumber soup:

Cucumbers, of course! I love to use delicate, thin-skinned Persian cucumbers in this recipe. Don’t forget to save a few slices for garnish! They add a nice crunch to this cool, creamy soup.
Greek yogurt – It gives the soup its delicious creamy texture and tangy flavor.
Extra-virgin olive oil – For richness.
Fresh herbs – I blend basil and dill into the soup and scatter more dill, fresh mint, or chives on top.
Lemon juice – It makes the soup nice and bright.
Garlic – It adds sharp depth of flavor.
Honey – Don’t worry – the honey doesn’t make this recipe sweet. Instead, it offsets the tang from the lemon and the bite from the raw garlic, creating a flavorful, well-balanced soup.
And salt and pepper – To make all the flavors pop!

Cold Cucumber Soup Serving Suggestions

This cold cucumber soup is a wonderful starter or side dish. On summer nights, I often serve it as part of a light dinner with a substantial salad like my Chickpea Salad, Panzanella Salad, or Cherry Tomato Couscous Salad. For a heartier meal, serve it as an appetizer with these Stuffed Zucchini Boats, Grilled Vegetable Skewers with Tzatziki, or my Roasted Vegetable Pasta.

This cucumber soup is also a lovely starter for a spring or summer brunch. I love pairing it with a few salads, like my Carrot Salad or Simple Green Salad, and a savory main course like a Frittata or Breakfast Casserole.

Finally, this cold cucumber soup is a perfect lunch on a hot summer day. Enjoy it with a hunk of good crusty bread or focaccia, a slice of avocado toast, or a simple sandwich. A Caprese Sandwich, a Chickpea Salad Sandwich, or an Egg Salad Sandwich would be a great choice.
