Chilled Cucumber Dill Yogurt Soup

A cool, creamy no-cook soup bursting with fresh cucumber, bright dill, and tangy yogurt that is ready in minutes and perfect for warm days.

Imagine opening your fridge on a sweltering summer afternoon and pulling out a bowl of something cool, creamy, and impossibly refreshing. That is exactly what this chilled cucumber dill yogurt soup delivers. It has a silky smooth texture with little pops of fresh cucumber, a clean tangy flavor from thick Greek yogurt, and the most lovely herby fragrance from handfuls of fresh dill. It tastes light and bright, almost like a spa in a bowl, and it is the kind of recipe that makes everyone at the table ask for seconds before they have finished their first serving.

This soup shines hardest in the heat of summer when cucumbers are plentiful and turning on the stove feels like a punishment. It is a no-cook recipe from start to finish, which means zero oven time and minimal cleanup. It works beautifully as a starter before a backyard barbecue, as a light lunch on its own, or as an elegant first course for a summer dinner party. It also comes together in about 20 minutes, with a short chill in the refrigerator to let all those flavors bloom, so you can make it ahead without any stress.

I first had a version of this soup at a friend's summer potluck and spent the rest of the afternoon figuring out how to recreate it at home. After a few rounds of testing, tweaking the garlic level, playing with lemon versus vinegar, and deciding exactly how chunky versus smooth I wanted it, I landed on this version. It has become my most-requested warm-weather recipe, and I genuinely make it at least once a week from June through August. Once you try it, I think it will earn a regular spot in your warm-weather lineup too.

Ingredients

Soup Base

2 large English cucumbers (about 2 lbs total), peeled and roughly chopped, divided

2 cups plain whole-milk Greek yogurt

1/2 cup cold water or cold vegetable broth

2 tablespoons fresh lemon juice (about 1 lemon)

1 tablespoon white wine vinegar

1 small clove garlic, minced

1/2 teaspoon kosher salt, plus more to taste

1/4 teaspoon freshly ground white or black pepper

1/4 teaspoon onion powder

Fresh Herbs and Add-ins

1/2 cup fresh dill fronds, loosely packed, plus more for garnish

2 tablespoons fresh mint leaves (optional but recommended)

2 green onions, trimmed and roughly chopped

1/2 small shallot, roughly chopped

Optional Toppings

Thinly sliced cucumber rounds or small diced cucumber

A drizzle of good extra-virgin olive oil

A few fresh dill sprigs

Thinly sliced radishes

A pinch of sumac or smoked paprika

Toasted pita wedges or flatbread for serving

Substitutions & Variations

★Regular full-fat sour cream can replace half or all of the Greek yogurt if you want a richer, slightly tangier flavor.

★Coconut yogurt works as a dairy-free swap for the Greek yogurt and still gives you that creamy, thick base.

★Persian cucumbers are a great substitute for English cucumbers and tend to be slightly sweeter with thinner skins.

★Apple cider vinegar can be used in place of white wine vinegar if that is what you have in your pantry.

★Freeze-dried dill can stand in for fresh dill in a pinch, but use only 1 tablespoon since it is much more concentrated in flavor.

Step-by-Step Instructions

1

Prep the Cucumbers

Peel both English cucumbers using a vegetable peeler, then slice them in half lengthwise. Use a spoon to scoop out the watery seed core from each half. This step is important because the seeds hold a lot of excess water that can make your soup too thin and diluted. Once seeded, roughly chop the cucumber into 1 to 2-inch chunks. Set aside about one-third cup of finely diced cucumber to stir in at the end for a little texture in the finished soup.

2

Combine Ingredients in the Blender

Add the chopped cucumber (reserving the small diced portion), Greek yogurt, cold water or vegetable broth, lemon juice, white wine vinegar, minced garlic, salt, pepper, and onion powder to a high-powered blender. Add the fresh dill fronds, mint leaves if using, green onions, and shallot on top of everything else. Starting with the liquid and yogurt at the bottom helps the blender run more smoothly without needing to push ingredients down repeatedly.

3

Blend Until Smooth

Secure the blender lid tightly and blend on high speed for about 60 to 90 seconds until the soup is completely smooth and a pale, creamy green. Stop once halfway through to scrape down the sides if needed. The color should be a soft, herby green rather than a very dark green. If the soup looks too thick to pour easily, add another 2 to 3 tablespoons of cold water and blend for another 10 seconds. Avoid over-blending once smooth, as this can warm the soup slightly.

4

Taste and Adjust Seasoning

Pour the blended soup into a large bowl and taste it carefully. Cold temperatures tend to mute flavors, so be generous with your seasoning at this stage. Add more salt a pinch at a time, more lemon juice for brightness, or a touch more vinegar for tang. If the garlic flavor feels too sharp, a small extra squeeze of lemon can help balance it. Stir the reserved finely diced cucumber into the bowl so there are small cool bites of texture throughout.

5

Chill the Soup

Cover the bowl tightly with plastic wrap or transfer the soup to an airtight container. Refrigerate for at least 1 hour before serving, and up to 8 hours ahead. This resting time is not just for getting the soup cold. It allows the garlic to mellow, the dill flavor to fully infuse into the yogurt base, and all the ingredients to come together into a cohesive, well-rounded flavor. If you are short on time, you can place it in the freezer for 20 minutes instead, but the flavor will not be quite as developed.

6

Stir Before Serving

When you are ready to serve, take the soup out of the refrigerator and give it a thorough stir. As it sits, the cucumber can release a little extra liquid that settles at the bottom, and a good stir brings everything back together. Check the consistency and if it has thickened more than you like, stir in a splash of cold water until it is back to your preferred texture. Taste once more and add a final pinch of salt if needed.

7

Prepare the Garnishes

While the soup is finishing its chill, get your garnishes ready so plating is quick and easy. Thinly slice a few cucumber rounds or cut a small amount of cucumber into tiny neat dice. Pull a few fresh dill sprigs from the bunch and pat them dry. If you are using radishes, slice them paper-thin on a mandoline or with a sharp knife. Having everything prepped and ready means you can plate and serve the soup while it is still perfectly cold.

8

Ladle and Garnish

Ladle the cold soup into chilled bowls. For an extra-cold presentation, place your serving bowls in the freezer for 5 minutes before ladling. Arrange a few cucumber slices or small dice in the center of each bowl, lay a sprig or two of fresh dill on top, and finish with a generous drizzle of good extra-virgin olive oil. Add a pinch of sumac or smoked paprika for a little color and depth. Serve immediately with toasted pita wedges or warm flatbread alongside.

Pro Baker Tips

✓Seeding the cucumber before blending is a must. The seeds contain a lot of water that will thin out your soup and dilute the flavor significantly.

✓For the smoothest possible texture, strain the blended soup through a fine mesh sieve before chilling. It takes an extra few minutes but gives you a restaurant-quality result.

✓Use the coldest yogurt you have straight from the refrigerator. Starting with cold ingredients helps keep the finished soup nicely chilled from the start.

✓Do not use non-fat Greek yogurt here. The fat in whole-milk yogurt gives the soup its creamy, satisfying body and prevents it from tasting too sharp or watery.

✓Make this soup the morning of the day you plan to serve it. An overnight chill actually makes the dill flavor more pronounced and the overall taste more balanced.

✓If your garlic flavor comes through too aggressively, blanch the clove in boiling water for 30 seconds before mincing to take the sharp edge off without losing the flavor.

Storage & Serving Notes

◆Store leftover soup in a sealed airtight container in the refrigerator for up to 3 days. Stir well before serving as some separation is normal.

◆Do not freeze this soup. The yogurt will separate and turn grainy when thawed, and the cucumber will become watery and lose its fresh texture.

◆Keep garnishes stored separately from the soup and add them fresh right before serving so they do not wilt or get soggy.

◆If the soup thickens in the fridge after a day or two, whisk in a small splash of cold water or broth to loosen it back to your desired consistency.

◆Serve the soup in pre-chilled bowls straight from the fridge to keep it as cold as possible from the first spoonful to the last.

Frequently Asked Questions

Can I make this soup the night before?

Yes, and it is actually one of the best make-ahead soups around. The flavor improves significantly after a full overnight chill, as the garlic mellows and the dill fully infuses into the yogurt. Just store it in a sealed container in the fridge and give it a good stir before serving. Hold off on adding the garnishes until right before you serve.

My soup turned out too thin. How do I fix it?

The most likely culprit is cucumber seeds or skin releasing too much water. To fix it, you can whisk in a few extra tablespoons of Greek yogurt until you reach your preferred thickness. Going forward, make sure to seed the cucumbers thoroughly and strain the blended soup through a sieve before chilling to remove excess liquid.

Can I use dried dill instead of fresh?

Fresh dill is strongly preferred here because its flavor is bright, grassy, and fragrant in a way dried dill just cannot fully replicate in a no-cook recipe. If fresh is not available, use 1 tablespoon of freeze-dried dill as a closer substitute. Regular dried dill works but results in a duller, less vibrant herb flavor overall.

Is this soup suitable for a low-calorie or low-carb diet?

It is naturally quite light at around 165 calories per bowl with very few carbohydrates, since it is built almost entirely from cucumber and yogurt. It is a great fit for low-carb eating. If you are following a strict low-fat plan, note that the recipe calls for whole-milk yogurt for texture, though you could use 2 percent Greek yogurt as a compromise.

Can I add avocado to this soup?

Absolutely, and it is a fantastic addition. Half a ripe avocado blended into the soup adds a buttery richness and makes it even creamier. Just know that avocado will thicken the soup considerably and can cause it to oxidize and turn slightly grey over time, so add it only if you plan to serve the soup the same day.
