Start by washing the cucumbers thoroughly. Peel them if desired, then slice them in half lengthwise. Remove the seeds with a spoon and chop the cucumber into smaller pieces.
In a blender or food processor, combine the chopped cucumbers, yogurt, vegetable broth, olive oil, lemon juice, dill, and garlic. Blend until the mixture is smooth and well combined.
Taste the soup and season with salt and pepper as desired. Blend again briefly to incorporate the seasoning.
Once blended, transfer the soup to a mixing bowl and refrigerate for about 10 minutes to chill, enhancing the flavors.
After chilling, give the soup a gentle stir. Serve it in bowls, garnishing with additional dill or a drizzle of olive oil if desired.
For added creaminess, you can substitute Greek yogurt for plain yogurt if preferred.
To enhance the flavor, consider adding a pinch of cumin or coriander before blending.
This soup can also be enjoyed with croutons or crusty bread for a heartier meal.
