Grate one medium cucumber and squeeze out excess moisture using a kitchen towel.

In a mixing bowl, combine the drained cucumber, Greek yogurt, minced garlic, olive oil, lemon juice, dill, and sea salt. Fold together until well integrated.

Stir the mixture well until creamy and smooth.

Cover and refrigerate for at least 30 minutes to allow flavors to meld.

Stir before serving and add extra olive oil and freshly cracked pepper if desired.
