Tzatziki origins:

Yogurt-based dips, spreads and sauces like this Greek tzatziki actually have their roots in the Ottoman empire where it was brought to Greece from Turkey and the word tzatziki is derived from the Turkish word, cacik (pronounced ja-jeek).

The difference is vast.

Cacik is a combination of yogurt, cucumber with garlic, herbs and thinned out with water added. It tends to be thinner to be very liquid-y whereas traditional traditional tzaziki cucumber sauce is thick and creamy with bright spots of tangy lemon and bright mint with a back note of pungent garlic.

Another popular cucumber and yogurt combination is raita (pronounced rah-ee-tah), an Indian condiment used to tame the heat of spicy foods.

The difference between tzatziki and raita starts with the yogurt. Tzatziki uses Greek yogurt whereas raita uses plain yogurt, which tends to be a little looser.

Tzatziki is made with bright herbs and aromatics while raita usually has a spice component like cumin, cayenne pepper or ginger and the cooling affect of the yogurt and cucumber are usually paired with spicy foods to tame the heat.

Straining cucumber for the yogurt sauce

Cucumber is made primarily of water and if you added freshly grated cucumber to the yogurt, it would add so much liquid that the sauce wouldn’t be thick and creamy. It needs to be strained first.

  1. To do that, line a strainer with a coffee filter and set the whole thing over a bowl. (You don’t have to use the coffee filter, if your strainer is very fine.)
  2. Sprinkle the cucumber with a little kosher salt (about 1/4 to 1/2 teaspoon).
  3. Let it rest for 20-30 minutes.
  4. Press the cucumber to squeeze out the excess liquid. (If you’re using the coffee filter, you can carefully lift it out of the strainer and fold it over the cucumber, then squeeze with your hands over the sink to remove as much liquid as possible.) Either method works, it just depends on what you have in your kitchen.

Don’t skip the straining step… Trust me, you’ll be surprised how much water is released from the cucumber.

Best yogurt to use for Greek tzatziki:

Classic Greek tzatziki is generally made with whole milk Greek yogurt, but it’s your kitchen (and I’m not the food police), so if you’ve only got low-fat or non-fat Greek yogurt, that’s fine.

Avoid regular plain or nonfat yogurt or European varieties as they are too loose for this cucumber yogurt sauce.

before and after garlic, lemon and kosher salt in a mortar.

I like to use a mortar and pestle for the garlic and lemon zest. It does a better job of pulverizing the ingredients and releasing their flavors and aromatics.

Grinding seasonings with a mortar and pestle

  1. Add the chopped garlic, lemon zest and kosher salt to the mortar (that’s the bowl portion).
  2. Use the pestle to grind and pound the garlic and lemon together until you have a fragrant paste. (There should be no chunks or solid bits of garlic).

How to make a garlic paste without a mortar and pestle

If you don’t own a mortar and pestle, there’s another way to achieve nearly the same result using a Chefs knife or Santoku and a cutting board. Here’s how:

  1. Finely chop the garlic on the cutting board.
  2. Add the lemon zest and sprinkle the pile with kosher salt.
  3. Use the flat blade of the knife to scrape, flatten and mash the garlic. (The grittiness of the kosher salt along with the pressing and scraping with the knife, breaks down the garlic into a paste.)
  4. It may take a few minutes for it to fully break down, but just keep working at it.
finishing the Greek tzatziki with fresh herbs, olive oil and cucumbers.

Best herbs for cucumber tzatziki

Fresh mint and dill are practically required for a good Greek tzatziki. Their flavor and aroma add a whole new dimension to the sauce. You can also use a bit of fresh Greek oregano, but be very sparing (1/4 to 1/2 teaspoon to start) as fresh oregano can easily overpower the sauce.

pro tip

Be sure to use fresh herbs and chop them finely so they are evenly distributed throughout the cucumber yogurt sauce. If you’re serving tzaziki as a mezze dipping sauce, decorate the dish with fresh herbs so diners can identify the flavors in the dip.

Use a good quality olive oil (preferably Greek) in the tzatziki. You want something that you would use for dipping bread into. I like to drizzle a little extra over the finished dish. It will get mixed in as people serve themselves, but it makes for a more inviting presentation.

Dipping pita bread into Greek tzatziki sauce.

Tzatziki is best the first day, but you can keep it for 2-3 days longer in the refrigerator. The garlic flavor will become more pronounced as it rests, so you may want to stir in a bit more yogurt (1-2 tablespoons) and a squeeze of lemon juice if you’re serving it several days later.

What to do with cucumber yogurt sauce

  • Use as a dip with soft pita wedges on a mezze platter with hummus, vegetables and olives.
  • Make Greek lamb sandwiches (gyros) with pita and tomatoes. Top generously with tzatziki.
  • Serve with Greek style turkey meatballs as a party appetizer or tasty dinner.
  • Use as a topping for grilled chicken, pork and lamb.
  • Serve with grilled bell peppers, zucchini, squash and eggplant for a healthy vegetarian meal.
