Chilled Cucumber Mint Soup with Greek Yogurt

Chilled cucumber soup is the easiest thing you can make on a hot day. You blend raw cucumbers with Greek yogurt, fresh mint, garlic, and lemon, then chill the bowl until it’s icy cold. No stove, no roux, no waiting on anything but the fridge. It takes about 15 minutes of hands-on work and serves four as a light starter. Cucumbers are roughly 95% water, which is exactly why this soup tastes so cooling. ([USDA FoodData Central](https://fdc.nal.usda.gov), 2023) One spoonful and the heat of the afternoon backs right off.

Key Takeaways

• No-cook recipe ready in 15 minutes plus chilling, with zero heat in the kitchen.
• Greek yogurt adds about 20 grams of protein per cup, far more than regular yogurt. ([USDA FoodData Central](https://fdc.nal.usda.gov), 2023)
• One serving lands near 90 calories, making it a genuinely light summer starter.
• Chilling for at least two hours is what fully develops the flavor and texture.
• Easy to flavor your way with dill, avocado, or a splash of buttermilk.

Why Chilled Cucumber Soup Works So Well in Summer

Cold soups solve a real summer problem: you want something nourishing without turning on the stove. According to the USDA, cucumbers contain roughly 95% water by weight, which makes this soup naturally hydrating and light at the same time. ([USDA FoodData Central](https://fdc.nal.usda.gov), 2023) The Greek yogurt brings body and tang, the mint brings a cooling lift, and the whole thing eats more like a refresher than a heavy first course.

There’s a reason cultures across the Mediterranean and the Balkans have made cold cucumber-yogurt soups for centuries. Tarator in Bulgaria, cacık in Turkey, and Persian abdoogh khiar all run on the same logic. Raw vegetables, cultured dairy, herbs, and a little acid. It’s smart hot-weather cooking that predates refrigeration.

This version keeps the spirit and trims the work. You don’t peel, you barely chop, and the blender does the rest. The hardest part is waiting for it to chill.

[PERSONAL EXPERIENCE] We’ve made this soup through three brutal New York Augusts, and the single biggest upgrade was salting the cucumbers first and letting them sit for ten minutes. That short draw pulls out excess water, so the finished soup is creamy instead of watery. Skip it and you’ll notice the difference in the bowl.

What Ingredients Do You Need?

Everything here is fresh, simple, and available at any grocery store in summer. The star is plain Greek yogurt, which carries far more protein than regular yogurt. According to USDA data, a single cup of plain Greek yogurt delivers around 20 grams of protein, roughly double that of conventional yogurt, thanks to straining. ([USDA FoodData Central](https://fdc.nal.usda.gov), 2023) That protein is what turns a thin cucumber puree into a satisfying soup.

For the Soup

• 2 large English cucumbers (about 1.5 lbs), roughly chopped
• 1 cup plain Greek yogurt (full-fat for the creamiest result)
• ⅓ cup fresh mint leaves, packed
• 1 small garlic clove
• 2 tablespoons fresh lemon juice
• 2 tablespoons extra-virgin olive oil, plus more to finish
• ¼ cup cold water (to thin, as needed)
• ½ teaspoon salt, plus more to taste
• Freshly ground black pepper

For Garnish

• Thin cucumber ribbons or small dice
• A few whole mint leaves
• A swirl of Greek yogurt
• A drizzle of olive oil and a pinch of flaky salt

English cucumbers are the easy choice here because their skins are thin and their seeds are small, so there’s no peeling and no seeding. If you only have regular cucumbers, peel them and scrape out the watery seed core with a spoon before blending. That keeps the soup from turning thin and bitter.

How Do You Make Chilled Cucumber Soup?

The method is almost too simple to call a recipe: salt, blend, chill, garnish. A blender does nearly all the work, and you control the texture by how long you run it. America’s Test Kitchen notes that a full two minutes of high-speed blending is what gives cold vegetable soups their signature silky, emulsified body rather than a grainy puree. ([America’s Test Kitchen](https://www.americastestkitchen.com), 2022) Patience at the blender pays off in the bowl.

Step-by-Step Instructions

1. Salt the cucumbers. Chop the cucumbers, toss with ½ teaspoon salt, and let them sit in a colander for 10 minutes. This draws out excess water so the soup stays thick and creamy.
2. Load the blender. Add the salted cucumbers, Greek yogurt, mint, garlic, lemon juice, and olive oil. Reserve a handful of cucumber for garnish.
3. Blend until silky. Run the blender on high for a full 1 to 2 minutes. Scrape down the sides once. The longer you blend, the smoother and more emulsified it gets.
4. Adjust the texture. Add cold water a tablespoon at a time until the soup is pourable but still has body. It should coat the back of a spoon.
5. Taste and season. Add salt, black pepper, and more lemon juice until it’s bright and balanced. Cold dulls flavor, so season it a touch bolder than feels right.
6. Chill thoroughly. Cover and refrigerate for at least 2 hours, ideally 4. This is not optional. Cold is half the point of this soup.
7. Garnish and serve. Ladle into chilled bowls. Top with cucumber, mint, a yogurt swirl, olive oil, and flaky salt.

[UNIQUE INSIGHT] Most recipes tell you to season the soup once and serve. Don’t. Taste it again right before serving, after it’s fully cold. Chilling mutes salt and acid noticeably, so a soup that tasted perfect warm will taste flat ice-cold. A final pinch of salt and squeeze of lemon at the table is what makes it sing.

Tips for the Best Cold Cucumber Soup

Small habits separate a good cold soup from a watery one. The most common failure is dilution, so technique matters more than ingredients here. Food scientists at Serious Eats point out that salting and draining watery vegetables before blending concentrates flavor and prevents a thin, washed-out result in cold preparations. ([Serious Eats](https://www.seriouseats.com), 2021) A few minutes of prep protects the whole bowl.

• Use full-fat Greek yogurt. Low-fat works, but full-fat gives the richest, most velvety texture and rounds out the acidity.
• Chill your bowls. Pop serving bowls in the freezer for 15 minutes before plating. The soup stays colder longer at the table.
• Don’t skip the salt-and-drain step. Ten minutes pulls out water that would otherwise thin your soup into cucumber juice.
• Add herbs gradually. Mint can take over fast. Start with ⅓ cup, blend, then taste before adding more.
• Balance with acid. If the soup tastes dull after chilling, it almost always needs lemon, not salt. Add a squeeze and taste again.
• Serve it the same day. Cucumber soup is best within 24 hours. After that the cucumber loses its fresh snap and the soup can separate.

What Are the Best Variations and Add-Ins?

This soup is a base you can steer in several directions. Cold soups are having a real moment, too: interest in chilled and no-cook summer recipes climbs sharply every June and July, with search demand for cold soups peaking in midsummer year after year. ([Google Trends](https://trends.google.com), 2024) Once you know the formula, you can riff endlessly.

Flavor Variations

• Cucumber-dill. Swap the mint for fresh dill and add a splash of buttermilk for a tangier, Eastern European feel.
• Cucumber-avocado. Blend in half a ripe avocado for a richer, creamier, more filling bowl.
• Spicy cucumber. Add a thin slice of jalapeño or a pinch of Aleppo pepper for gentle heat against the cool.
• Herb garden. Use a mix of mint, dill, and parsley for a more layered, green flavor.

Garnishes and Add-Ins

• Crunch: toasted pine nuts, chopped walnuts, or croutons for textural contrast.
• Protein: a few cooked, chilled shrimp or a spoon of crab on top turns it into a light lunch.
• Brightness: diced tomato, radish, or a few pomegranate seeds add color and pop.
• Richness: a drizzle of good olive oil and crumbled feta over the top.

How Do You Store Chilled Cucumber Soup?

Cold soups are best fresh, but they keep for a short window if stored right. The USDA advises refrigerating perishable foods at 40°F or below and using dairy-based dishes within a few days for safety and quality. ([USDA Food Safety and Inspection Service](https://www.fsis.usda.gov), 2023) For this soup, sooner is better because the cucumber’s fresh texture fades over time.

• Refrigerator life: store in a sealed container for up to 2 days. Stir well before serving, as it may separate slightly.
• Make-ahead: blend up to a day in advance, which also doubles as the required chill time.
• Freezing: not recommended. The yogurt separates and the cucumber turns watery and grainy when thawed.
• Re-season: always taste and adjust salt and lemon after storage, since cold and time both mute the flavor.

Frequently Asked Questions About Chilled Cucumber Soup

Do I need to peel the cucumbers?

Not if you use English cucumbers. Their skins are thin and tender, and the skin adds color and a little fiber to the soup. If you’re using regular field cucumbers, peel them, because their skins are thicker and can taste waxy or bitter. Either way, leaving a little skin on gives the soup its pale green color and a fresher flavor.

Can I make this soup dairy-free?

Yes. Swap the Greek yogurt for a thick, unsweetened plant-based yogurt made from coconut, almond, or cashew. Coconut yogurt gives the richest texture and closest body to dairy. You’ll lose some of the protein, so consider blending in a tablespoon of cashew butter or half an avocado to keep the soup creamy and substantial rather than thin.

Why is my cucumber soup watery?

Watery soup almost always comes from skipping the salt-and-drain step. Cucumbers are about 95% water, so blending them raw without draining releases all that liquid. Toss the chopped cucumbers with salt, let them sit ten minutes, and discard the drained liquid before blending. Using full-fat Greek yogurt and going easy on added water also keeps the texture thick and spoonable.

How long does chilled cucumber soup last?

It keeps in a sealed container in the refrigerator for up to 2 days, though it’s best within the first 24 hours. The cucumber loses its crisp freshness over time and the yogurt may separate slightly. Just stir it well before serving and taste for salt and lemon, since chilling and time both dull the seasoning. Don’t freeze it, as the texture breaks down badly.

Can I serve this as a main course?

Yes, with a few additions. On its own it’s a light starter at about 90 calories per serving. To make it a meal, top each bowl with chilled cooked shrimp, lump crab, or a soft-boiled egg, and serve it with crusty bread or a grain salad on the side. The Greek yogurt already brings real protein, so a modest topping turns it into a satisfying summer lunch.
