Start by grating the cucumber into a bowl. Since cucumbers contain a lot of moisture, squeeze out the excess liquid using a cheesecloth, strainer, or paper towels. This prevents the dip from becoming watery and keeps it thick and creamy.
In a medium bowl, combine the Greek yogurt, shredded cucumber, lemon juice, and minced garlic. Stir well to ensure everything is evenly distributed.
Toss in the freshly chopped dill and parsley, then season with salt and pepper. Mix everything thoroughly. The fresh herbs not only enhance the flavor but also add a vibrant pop of color.
For the best flavor, let the Tzatziki chill in the refrigerator for at least 30 minutes before serving. Enjoy it cold with pita bread, fresh vegetables, crackers, or as a zesty sauce for grilled dishes.
