Grate the cucumber and place it in a clean kitchen towel. Squeeze out as much excess liquid as possible to prevent the tzatziki from becoming watery.
In a medium bowl, combine the Greek yogurt, grated and drained cucumber, minced garlic, olive oil, lemon juice, and chopped dill.
Mix well until all the ingredients are fully incorporated.
Season with salt and pepper to taste.
Stir again to ensure the seasoning is evenly distributed.
Cover the bowl and refrigerate the tzatziki for at least 1 hour before serving to allow the flavors to meld together.
Enjoy your meal!
