Authentic Greek Tzatziki Sauce.

The famous Greek dip tzatziki! Anyone that has travelled to Greece has tried this refreshing, garlicky, tangy sauce. Greeks usually have it with grilled meat and it’s one of the key ingredients in ‘souvlaki’, a pitta bread wrap with gyros or skewers, tzatziki, tomato and onion slices.

Here, I’m sharing with you an authentic tzatziki sauce recipe that my mother taught me how to make and it’s the way we make it in most places in Greece. The main ingredients are yogurt and cucumber, and the key for success is to use a strained Greek yogurt that is thicker than normal yogurt and to squeeze and drain well the grated cucumber.

Ingredients & How-to

To make this authentic tzatziki sauce, you will need Greek strained yogurt, cucumber, garlic, olive oil, vinegar, salt, and optionally some fresh dill. So let’s get started!

Ingredients for tzatziki sauce.

01. I start by grating the cucumber. I’m using a bowl and a tea towel to drain any excess water from the grated cucumber. I’m squeezing hard the towel to remove any water and now the cucumber is ready to use. The remaining water can be used in smoothies if you don’t want to waste it.

02. Now, in a big bowl I’m mixing all the ingredients together, the yogurt, grated cucumber, olive oil, vinegar, chopped garlic, chopped dill and a little bit of salt.

Make sure that you use a strained Greek yogurt type rather than a greek style one that will make your tzatziki more runny. As for the garlic, you could use one or two cloves depending on how sharp you want it to taste. I like to use a garlic presser but you could also use pestle & mortar or cut it very finely.

Serving suggestions

This tzatziki sauce goes well with meat, veggies or just bread. It’s much healthier than mayonnaise based sauces as it’s less fatty and refreshing from the cucumber. We love to have it with

  • Grilled meat
  • Grilled vegetables
  • Bread and pitta bread
  • Raw vegetables like carrot sticks
  • As sauce in wraps and sandwiches

If you are sharing the tzatziki dip with little ones under 12 months, then I recommend leaving out the salt as you need to keep the daily salt intake to a minimum.


You can store any leftover tzatziki sauce in an airtight container in the fridge for up to 4 days. After that, the sauce might get more runny and it will lose some of its flavor.


  • What does tzatziki sauce taste like? Tzatziki sauce has a refreshing, tangy taste due to its main ingredients being Greek yogurt and cucumber. The garlic and vinegar give it a sharpness that sometimes can be a bit fiery if you add too much garlic, the way many Greeks prefer it. The addition of fresh dill is optional but very popular in Greece as it adds a nice herbal aroma to tzatziki.

  • Can you freeze tzatziki sauce? You could freeze the tzatziki sauce for up to 2 months in an airtight container. If you want to avoid your tzatziki sauce getting runny when defrosted, you must make sure it is prepared with thick strained Greek yogurt and the grated cucumber is well drained. When defrosted, you could add another tablespoon of yogurt to get creamier.

  • Why is my tzatziki runny? If you are tzatziki is runny, then you probably have used a yogurt that is runny and not strained or you didn’t squeeze out the excess water from the grated cucumbers.

  • Do I put vinegar or lemon in tzatziki sauce? You will find many recipes using lemon juice for the tzatziki sauce, but the authentic recipe is using vinegar to add some acidity to the tzatziki sauce. Lemon juice in fact could cause some separation in yogurt and result in a more runny tzatziki sauce.
