Wash the cucumbers thoroughly and slice them thinly using a sharp knife or mandoline slicer so the pieces are evenly sized and absorb the dressing well.
Place the sliced cucumbers in a large mixing bowl and set them aside while you prepare the dressing.
In a separate bowl combine Greek yogurt, lemon juice, olive oil, minced garlic, chopped fresh dill, salt, and black pepper.
Whisk the mixture until it becomes smooth and creamy with all ingredients evenly blended.
Pour the creamy dressing over the sliced cucumbers.
Gently toss the cucumbers with the dressing until every slice is evenly coated.
Taste the salad and adjust seasoning with extra salt, pepper, or lemon juice if desired.
Cover the bowl and place it in the refrigerator for about 10–20 minutes so the flavors can blend together.
Before serving, give the salad one final gentle stir.
Garnish with additional fresh dill or cracked black pepper.
Serve chilled for the best refreshing flavor and creamy texture.
