Ingredients You’ll Need

This Cold Cucumber Soup with Walnuts, Herbs, and Sumac Recipe relies on straightforward but thoughtfully chosen ingredients. Each plays a crucial role in building layers of taste, texture, and color that make the soup so irresistible.

• Walnuts: Toast them gently to bring out a rich, warm nuttiness that adds crunch and depth.
• Persian or English cucumber: These varieties have fewer seeds and a mild, crisp flavor perfect for a smooth soup.
• Whole milk plain yogurt (not Greek): Provides creaminess and a subtle tang that balances the soup perfectly.
• Ice water: Keeps the soup light, chill, and wonderfully refreshing.
• Chopped fresh herbs (parsley, basil, dill, mint): Offers bright, aromatic notes that make every spoonful lively and fresh.
• Golden raisins: A hint of natural sweetness to contrast the savory elements.
• Sumac: A lemony, slightly tart spice that finishes the soup with a vibrant zing.
• Kosher salt: Enhances all the flavors and ties everything together.

How to Make Cold Cucumber Soup with Walnuts, Herbs, and Sumac Recipe

Step 1: Toast the walnuts

Start by warming a small skillet over medium-low heat and swirling the walnuts in it. Toasting them gently for about 7 minutes until they become soft, golden, and wonderfully fragrant releases their oils and deepens their flavor dramatically. Once toasted, transfer to a cutting board and chop finely to prepare for the soup.

Step 2: Prep the cucumber

Next, take one Persian or English cucumber and slice about 1/4 of it into thin rounds—these will add a fresh crunch as a garnish. For the rest, slice the cucumber lengthwise into quarters and carefully scoop out the seeds with a metal spoon to avoid any bitterness. Finely chop the seeded cucumber to create a lovely texture in the soup without watery pockets from the seeds.

Step 3: Make and chill the soup

In a large mixing bowl, whisk together the whole milk plain yogurt with ice water until smooth and creamy. This combination ensures the soup stays light but luxuriously creamy. Fold in the chopped cucumber, vibrant herbs, juicy golden raisins, and the finely chopped toasted walnuts. Season the mix with a pinch of kosher salt. Cover the bowl and place it in the refrigerator to chill for at least one hour, allowing all the flavors to mingle beautifully—though it can happily sit for up to 3 days.

Step 4: Serve cold and fresh

When you’re ready to enjoy your Cold Cucumber Soup with Walnuts, Herbs, and Sumac Recipe, ladle it evenly into four bowls. Sprinkle an extra dusting of sumac and a scattering of fresh herbs on top for a stunning presentation and an added burst of flavor. Add the reserved cucumber slices to each bowl as a final touch of texture and vibrant green color.

Garnishes

The garnishes truly make this soup shine. Besides the thin cucumber slices and fresh herbs, a sprinkle of sumac on top gives a tart, ruby-red pop that brightens the dish visually and in taste.

Side Dishes

This cold soup pairs beautifully with warm, crusty bread or a light flatbread to scoop and savor the creamy texture. It also complements Mediterranean-inspired salads or grilled vegetable dishes wonderfully, elevating any summer lunch or dinner without feeling too heavy.

Creative Ways to Present

For entertaining, serve the soup in chilled glass cups or small mason jars for a rustic yet elegant look. Layer in some finely chopped herbs and a sprinkle of walnuts on top for visual appeal. Alternatively, serve it alongside an antipasto platter to impress guests with a fresh, flavorful starter that sets the tone for a memorable meal.

Make Ahead and Storage

Storing Leftovers

If you have any leftovers from your Cold Cucumber Soup with Walnuts, Herbs, and Sumac Recipe, store them tightly covered in the refrigerator. Because this soup is best enjoyed chilled, keeping it cold preserves the fresh flavors and creamy texture for up to three days.

Freezing

Freezing this soup is not recommended since yogurt and fresh cucumbers do not freeze well together; the texture would become grainy and watery once thawed. It’s best to enjoy it fresh or refrigerated for a few days.

Reheating

This soup is meant to be served cold, so reheating is generally not needed. If you prefer it slightly less chilly, just let it sit at room temperature for 10 minutes before serving. Avoid heating it on the stove or microwave to maintain the yogurt’s creamy consistency and fresh flavors.

FAQs

Can I substitute Greek yogurt for plain yogurt in this recipe?

While Greek yogurt is thicker and creamier, it has a tangier taste and less liquid. This recipe calls for whole milk plain yogurt to keep the soup light and silky; substituting Greek yogurt would require thinning it with extra water or milk and might change the texture noticeably.

What kinds of herbs work best in the Cold Cucumber Soup with Walnuts, Herbs, and Sumac Recipe?

The best herbs are those with fresh, bright flavors like parsley, basil, dill, and mint. You can mix and match or use just one depending on your preference, but the combination adds complexity and vibrant green color that elevate the soup beautifully.

Can I make this soup vegan or dairy-free?

Yes! Use a plant-based yogurt such as coconut or almond milk yogurt instead of dairy yogurt. The texture and tanginess might differ slightly, but the soup will still be refreshing and delicious.

How important is the sumac in this recipe?

Sumac adds a unique citrusy tang that elevates this soup’s flavor profile, making it bright and exciting. While you can omit it if unavailable, adding sumac really completes the dish and is highly recommended.

Is this soup suitable for meal prep or packed lunches?

Absolutely! Because it keeps so well in the fridge and actually tastes better after a few hours of chilling, it’s perfect for preparing ahead and taking to work or school. Just keep it in a sealed container and give it a good stir before serving.
