If you're looking for an easy soup recipe for the summer heat, cucumbers are the perfect choice. English cucumbers have a seedless skin and are much more delicate in flavor than slicing cucumbers, which have a thick and waxy skin. You can also use a variety of vegetables to garnish the chilled soup. In addition to cucumbers, you can also add chopped tomatoes, avocado, and fresh herbs.

Cucumber Summer Soup
Blending cucumbers, yogurt, and herbs – the secret to our velvety-smooth cucumber summer soup.


  • 4 large cucumbers, peeled and chopped
  • 1 cup plain yogurt
  • 2 cloves garlic, minced
  • 1/4 cup fresh dill, chopped
  • 1/4 cup fresh mint leaves
  • 2 tablespoons fresh lemon juice
  • Salt and pepper to taste


  • Start by preparing the cucumbers. Peel and chop them into chunks. Removing the seeds is optional but can make the soup smoother.
  • Add the chopped cucumbers to your blender.
  • Next, add the plain yogurt, minced garlic, fresh dill, fresh mint leaves, and fresh lemon juice to the blender.
  • Season with a pinch of salt and a dash of pepper to taste.

Cooking Tips

  • The Power of Fresh Cucumbers: To achieve that vibrant, crisp flavor, always opt for the freshest cucumbers. Look for firm cucumbers without any spongy spots, and consider using homegrown or organic cucumbers if available.
  • Dealing with Seeds: While cucumber seeds can be included, removing them can result in a smoother soup. If you prefer a silkier texture, you can scoop out the seeds before blending.
  • Balance the Tang: Adjust the amount of lemon juice and yogurt to your taste. Start with the suggested quantities in the recipe, but don’t hesitate to add a little more lemon juice for extra zing or yogurt for creaminess.
  • Keep It Chilled: Refrigerating your soup for at least an hour before serving is crucial. This allows the flavors to meld and the soup to reach the desired temperature for a refreshing experience.
  • Garnish with Finesse: Elevate your presentation with a creative garnish. Fresh dill, mint leaves, and a cucumber slice are classic choices, but you can also consider a drizzle of olive oil or a dollop of Greek yogurt.

  • Zesty Garnishes: Besides the classic garnishes mentioned earlier, you can experiment with additions like smoked paprika, a swirl of pesto, or a few capers for an extra burst of flavor.
  • Fresh Herbs: Fresh herbs like basil, chives, or tarragon can also be used as garnishes or mixed into the soup for an added layer of complexity.
  • Beverage Pairings: For a well-rounded experience, consider pairing your soup with a crisp white wine, a light rosé, or even a sparkling water with a twist of lemon.
