After peeling the cucumber, grate it. If your Greek yogurt isn't very thick, squeeze as much water as possible from the grated cucumber using your hands. This step is essential to avoid a watery Tzatziki.
In a mixing bowl, combine the Greek yogurt, squeezed cucumber, finely minced garlic, and chopped dill. Mix them well.
Add salt and ground black pepper to your taste. Mix again until all ingredients are well-combined.
Transfer the Tzatziki sauce to a container with a tight-fitting lid. Let it chill in the refrigerator for at least 1 hour. This allows the flavours to meld together.
Before serving, drizzle the olive oil and sprinkle with a pinch of fresh dill. Tzatziki is perfect as a dip for Greek flatbread, sauce to go with Gyros or Souvlaki, or even as a refreshing side with grilled meats. Enjoy!
Notes:
Can I use regular yoghurt instead of Greek yoghurt? Yes, but Greek yoghurt is thicker, providing the desired consistency for Tzatziki. If using regular yoghurt, consider straining it to remove excess liquid.
Herb Choices: Always use fresh dill for an authentic taste. If you can't find fresh dill, you can substitute with half quantity of dried dill.
Storage Recommendations: Tzatziki can be stored in the fridge for 2-3 days, but it's best consumed within the first day or two for optimal freshness and taste.
