My husband’s Nonna lived next door to a lovely Greek couple for quite awhile. 

Ever the the chatty, friendly lady, she made friends with the couple and they would regularly invite each other over for dinners.

While Nonna would always serve up a mix of Northern/American and Italian cuisine, her neighbors would mostly make traditional Greek food.

Nonna, not one to like to show up empty handed at any gathering, would always ask what she could bring.

Her neighbor would normally say nothing, but eventually gave in and asked her to bring the tzatziki sauce recipe that her family had shared with her.

Nonna was happy to oblige and whip together this easy, creamy spread anytime.

What is Tzatziki Sauce?

Tzatziki sauce is a yogurt based dipped popular in Greece and other Mediterranean countries.

Most recipes combine Greek yogurt, chopped cucumber and fresh garlic.

Sometimes you’ll see other ingredients like lemon juice, dill or other spices.

I’m giving you two versions of this yummy recipe: the more authentic version Nonna’s neighbor taught her and a more spiced up, herbed version that my own family tends to prefer.

Ingredients

For the base authentic version, you’ll need:

  • Cucumbers– You’ll want to use English or Hot House cucumbers. These are the ones sold wrapped in plastic wrap at the store. Peel them and grate them.
  • Sour cream– Full fat sour cream will give the best flavor.
  • Greek yogurt– Plain, full fat Greek yogurt. Be sure not to pick up flavored Greek yogurt.
  • Garlic– Minced fresh garlic works much better in this than dried garlic powder.
  • Extra Virgin Olive Oil– For a little extra richness. Don’t substitute another oil.

Optional ingredients include:

  • Lemon juice– Go for fresh lemon juice over bottled for optimal flavor.
  • Dill– Fresh is best. Chop it up well.
  • Oregano– Here you can use the dried spice.

How to Make

The Authentic Version

Part of the reason why Nonna loves making this is it’s so easy to make.

To do it, use a vegetable peeler to peel the cucumbers.

Once you’ve peeled then, grate them using a box grater.

Add the grated cucumber to a waiting colander set in a sink.

Then, sprinkle 1 teaspoon of salt over the cucumbers to draw the water out.

Stir the cucumbers to distribute the salt and let them sit undisturbed for 15 minutes.

After 15 minutes, using the back of a sturdy wooden spoon, press the cucumbers against the edges of the colander to release excess water. Do this several times.

Add the sour cream, yogurt, garlic and oil to a mixing bowl and whisk everything together until evenly combined.

Once combined, fold in the cucumbers.

The authentic tzatziki can be served as is, or stored until ready to use.

The Seasoned Version

Making this version is pretty much the same, you just add in the extra spices when you are whisking the sour cream, yogurt, garlic and oil to the mixing bowl.

That’s it!

For everything else, the process stays exactly the same.

How to Use It

Part of the appeal to this recipe is just how versatile it is!

You can use it as a dip for:

  • cucumbers
  • pita chips
  • carrot and celery sticks
  • sweet peppers
  • cherry tomatoes
  • mushrooms
  • pretzels
  • crackers
  • kebobs or grilled meats
  • falafel

You can also use it as a spread for gyros, pitas and sandwiches.

Or, to make the leftovers into a sauce (think pasta salad, chicken salad, or potato salad) just thin it with a bit of milk.

For a creamy Greek salad dressing, thin the sauce with more olive oil.

Storing Leftovers

Store leftovers covered in an airtight container in the fridge for up to 4 days.

After that it will start to go bad.

Tips and Tricks

  • Don’t have Greek yogurt? Some places it can be hard to find. Spoon plain regular yogurt into a coffee filter and the excess moisture drains away quickly, leaving behind a much thicker yogurt similar in consistency to the Greek version
  • This recipe makes a lot- perfect for entertaining or serving a crowd. If you are planning to only serve your family or a smaller crowd, half the recipe.
  • Can’t find English cucumbers or have a ton of regular cucumbers growing it your garden? Feel free to use them, but there’s more moisture to squeeze out. Make sure you drain them well in order to avoid a watery sauce.
