Chilled Cucumber Soup with Avocado and Dill

Too hot to cook? Give this delicious chilled soup a try! Cooling cucumber, vibrant yellow and jalapeño peppers, chopped fresh dill and creamy avocado form the base of this easy vegetarian soup.

The preparation itself couldn't be simpler...a brief stint in the blender followed by a few hours in the fridge. Done. When you are ready to serve, a few simple garnishes really elevate this soup from good to great: Chopped farm stand tomatoes, sautèed bread cubes and a drizzle of good extra-virgin olive oil. Perfect for those sultry summer days!

Three bowls of chilled cucumber soup topped with croutons, dill and chopped tomatoes.

The Story Behind This Recipe

I studied in southern Spain during college, and on those unbearably hot days in August and early September my house mother would prepare a big bowl of gazpacho to keep in the fridge. Every meal began with a small bowl of this cooling, delicious elixir. I wanted to come up with something with the same sense of refreshing ease and seasonality, but with ingredients common to the Nordic region.

The Ingredients

For the Soup:

Labeled ingredients for Chilled Cucumber Soup

For the Garnishes:

Labeled ingredients for toppings for Chilled Cucumber Soup.
  • Cucumbers, yellow and jalapeño peppers, fresh dill, garlic and an avocado form the creamy vegetable base of this fresh summertime soup. Regular garden cucumbers or English (sometimes called seedless) cucumbers will work just fine in this recipe.
  • Skyr (Icelandic yogurt) provides a bit of tangy creaminess (feel free to substitute Greek yogurt if you like).
  • Freshly squeezed lemon juice brings just the right amount of acidity and brightness to the final product.
  • This soup would not be complete with the toppings: Homemade rustic croutons for crunch, chopped fresh tomatoes and a drizzle of olive oil for added freshness, texture and flavor.

How to Make This Recipe

  • Begin by roughly chopping your vegetables and the dill.
Chopped dill, yellow peppers and cucumbers.
  • Add the remainder of the cucumbers, the peppers, dill and garlic to the blender container along with the pureed cucumbers. Blend again until smooth.

  • Halve the avocado, remove the pit and scoop the flesh into the blender. Add the skyr and blend again until smooth.
  • Finally, add 2 tablespoons of fresh lemon juice and 1 ½ teaspoons coarse salt and blend one last time. Transfer the mixture to a bowl and adjust the seasoning as necessary (you might want to add a little more lemon juice or salt). Cover the soup and transfer it to the refrigerator to chill completely, at least a few hours or up to two days.
  • When you are ready to serve, make the croutons: Cut the bread into ½ inch cubes and heat the olive oil in a large skillet over medium heat. Add the bread cubes and sauté until crisp and lightly browned, about 3-5 minutes.  Transfer to a paper towel lined plate and season with coarse salt and pepper.  Set aside.

Expert Tips

  • It really helps to have a high-powered blender. They can be quite expensive, but are one of the best kitchen investments you can make, in my opinion. If your blender is just so-so and the soup is not as smooth as you would like, you can always run it through a fine mesh sieve to remove any remaining bits of unprocessed vegetable.
  • After the soup chills in the refrigerator, give it a good stir before serving. The soup will separate slightly during the cooling process.

FAQs

How do I store this chilled cucumber soup?

Store the soup, tightly covered, in the refrigerator and be sure to give it a good stir prior to serving as it will have separated slightly while it was chilling.

How long does this soup keep in the refrigerator?

This soup will keep in the refrigerator for 2-3 days. I don't recommend freezing this soup.

I can't find skyr (Icelandic yogurt). Can I substitute something else?

Yes! Greek yogurt works just fine in this recipe in place of the skyr.

Can I make this soup vegan?

Absolutely! Simply substitute a plant-based yogurt for the skyr.
