Tzatziki is a cold Greek sauce made from strained yogurt, grated cucumber, garlic, olive oil, and lemon or vinegar, usually finished with dill or mint. It is thick, tangy, and cooling — built to sit alongside hot grilled meat, which is exactly why it turns up on almost every Mediterranean plate in NYC.
What is tzatziki made of?
Five things, and the ratio matters more than the list.
- Strained yogurt. Thick Greek-style yogurt, not thin drinking yogurt. This is the body of the sauce.
- Cucumber. Grated, then squeezed dry. Skipping the squeeze is the single most common reason homemade tzatziki turns watery within an hour.
- Garlic. Raw and finely minced or crushed. Assertive but not overwhelming.
- Acid and fat. Lemon juice or red wine vinegar for brightness, good olive oil for richness.
- Herbs. Dill is the Greek standard. Mint appears in some regional versions, and a few kitchens use both.
Salt is the sixth ingredient nobody lists but everybody notices. Under-salted tzatziki tastes flat and chalky no matter how good the yogurt was.
Where does tzatziki come from?
Tzatziki is Greek in its current form, but the family it belongs to is much older and much wider. Yogurt-and-cucumber preparations run across the eastern Mediterranean, the Balkans, and into South and Central Asia — Turkish cacık, Bulgarian tarator, Persian mast-o-khiar, and Indian cucumber raita are all cousins.
The name itself travelled: the Greek tzatziki comes from Turkish cacık, which traces back to a Persian root. The differences between the versions are real but small — consistency, herb choice, whether it is served as a dip or thinned into a cold soup.
What does tzatziki taste like?
Cool, tangy, and garlicky, with a clean cucumber freshness underneath. It is a contrast sauce, not a coating sauce — its job is to cut through char and fat rather than to add richness.
That is worth understanding if you are choosing between sauces at the counter. A well-made tzatziki should make the second half of a plate of shawarma taste as good as the first bite. If it just tastes creamy, it is not doing its job.
How is tzatziki different from other Mediterranean sauces?
The four sauces you will meet most often on a Mediterranean menu do genuinely different things:
| Sauce | Base | Flavor | Best with |
|---|---|---|---|
| Tzatziki | Strained yogurt + cucumber | Cool, tangy, garlicky | Grilled meats, gyro, souvlaki, falafel |
| Tahini | Ground sesame paste | Nutty, earthy, rich | Falafel, roasted vegetables, bowls |
| Toum | Emulsified garlic + oil | Sharp, intensely garlicky | Chicken shawarma |
| Harissa | Chili peppers + spices | Smoky, hot | Anything that needs heat |
The practical version: tzatziki cools, tahini enriches, toum sharpens, and harissa heats. Ordering two that do the same job is a wasted opportunity; pairing tzatziki with harissa is one of the most reliable combinations on any Mediterranean plate.
Is tzatziki healthy?
It is one of the lighter sauce options on a Mediterranean menu. Yogurt contributes protein and calcium, cucumber adds water and volume, and olive oil supplies unsaturated fat. Compared with mayonnaise-based or heavily oil-based dressings, a yogurt base is typically lower in calories for the same portion.
Two honest qualifications. Tzatziki contains dairy, so it is not vegan — plant-based diners are better served by tahini or harissa. And exact nutrition varies with how much olive oil a given kitchen uses, so treat any specific calorie figure you read online with skepticism.
What do you eat tzatziki with?
Anything grilled, and most things fried. Traditionally it accompanies gyro and souvlaki; it works just as well as a dip for warm pita, a spread inside a wrap, or a spoonful over a grain bowl.
It is also the standard partner for falafel outside of strictly vegan contexts, and it is one of the few sauces that improves cold leftovers — it keeps a reheated plate from tasting tired.

Tzatziki FAQs
Is tzatziki the same as raita?
No, though they are close relatives. Both are yogurt-and-cucumber sauces, but tzatziki is Greek and built on garlic, dill, olive oil, and strained yogurt, while Indian raita is typically thinner and seasoned with cumin, coriander, or mint instead of garlic.
Is tzatziki vegan or dairy-free?
No. Traditional tzatziki is yogurt-based and therefore contains dairy. Vegetarians can eat it, but vegan and dairy-free diners should choose tahini, hummus, or harissa instead.
Is tzatziki gluten-free?
The sauce itself contains no gluten — yogurt, cucumber, garlic, oil, acid, and herbs. What it is served with is the variable, so pita and wraps are the thing to ask about rather than the tzatziki.
How do you pronounce tzatziki?
Roughly “dza-DZEE-kee.” The opening sound is closer to the “ds” in “kids” than to a hard T, and the stress lands on the middle syllable.
How long does tzatziki last in the fridge?
Homemade tzatziki generally keeps about three to four days refrigerated in a sealed container. It may separate slightly — stir it back together. The garlic also grows stronger over time, so day three tastes noticeably sharper than day one.
Why is my tzatziki watery?
Almost always the cucumber. Grated cucumber releases a large amount of water, so it needs to be salted and squeezed dry before it goes into the yogurt. Using unstrained yogurt compounds the problem.
Is tzatziki at Zazu halal?
Yes. Everything on the Zazu menu is halal, including our house-made sauces.
