Prepare your cucumber by peeling and discarding the skin and dicing the cucumber.
Transfer it to a bowl and add salt and pepper.
Mix to combine, then blot away excess moisture with a clean paper towel.
Add cucumber, garlic, yogurt, parsley, onion powder, garlic powder, balsamic vinegar, and olive oil to a blender. Blend until the consistency of your tzatziki is smooth, thick, and creamy.
Transfer the tzatziki sauce to a bowl once it has reached your preferred consistency.
Serve with pita slices, and enjoy :)

Notes
If your tzatziki turns out too thick, you can thin it with a bit of water, olive oil, or lemon juice. Conversely, if it's too thin, add more yogurt.
While you can enjoy tzatziki right after making it, it's even better after it has had some time to chill in the refrigerator. This allows the flavors to meld and develop, resulting in better, brighter flavors in your tzatziki.
Feel free to experiment with different herbs and seasonings. Dill is a popular herb choice in tzatziki. However, mint, cilantro, or parsley can also create new and exciting flavor profiles. You can add a touch of honey for sweetness, a pinch of ground cumin for depth, or even some chopped olives or capers for a unique twist.
Use full-fat Greek yogurt for a creamier texture.
Grate the cucumber and squeeze out excess water for a thicker sauce.
Adjust garlic quantity to your taste preference.
Use a food processor to blend the ingredients for a smoother consistency.
