Authentic Tzatziki with Olive Oil: The Real Greek Recipe

Few dishes capture the spirit of a Greek table like tzatziki. Cool, creamy and fragrant with garlic, it arrives the moment you sit down at a taverna — a small bowl beside warm bread, ready to be scooped, spread and shared. Yet the version many of us know from the chilled supermarket aisle, thin and sharp, is a world away from the real thing.

Authentic tzatziki is thick enough to hold a spoon upright, balanced between tangy yoghurt and mellow garlic, and finished with a generous pour of good extra virgin olive oil. Made well, it takes barely fifteen minutes of hands-on work. Below is the traditional Greek recipe, along with the small details — draining the cucumber, choosing the right yoghurt and, above all, the olive oil — that separate a good tzatziki from an unforgettable one.

What is tzatziki?

Tzatziki is a classic Greek dip and sauce made from strained yoghurt, grated cucumber, garlic, olive oil and a little acidity from red wine vinegar or lemon. It belongs to the wider Mediterranean family of yoghurt-and-cucumber preparations, but the Greek version is defined by its thickness and its confident use of garlic and olive oil.

On a Greek table it plays several roles at once. It is a cornerstone of any meze spread, a cooling sauce for grilled meats such as souvlaki and gyros, a partner for fried vegetables like courgettes and aubergines, and — perhaps best of all — something to eat simply with a torn piece of bread. Its charm lies in its restraint: a handful of humble ingredients, treated with care.

Why olive oil matters in tzatziki

Olive oil is not a garnish in tzatziki — it is a defining ingredient. Many cooks whisk a spoonful directly into the yoghurt, where it emulsifies and gives the dip its characteristic silky, rounded body. Almost everyone finishes the bowl with a final drizzle just before serving, which is where the oil's aroma really comes through. If you have ever wondered why olive oil belongs in tzatziki at all, this is the answer: it carries flavour, softens the bite of raw garlic and turns a simple yoghurt mixture into something luxurious.

Because there are so few ingredients, quality is impossible to hide. A grassy, peppery extra virgin olive oil lifts the whole bowl, adding fruitiness and a gentle bitterness that balances the sourness of the yoghurt. Our naturally cloudy, hand-harvested oil from the Peloponnese has exactly the buttery, peppery character that traditional tzatziki calls for. A flat, over-refined oil, by contrast, leaves the dip tasting equally flat — so this is one recipe where it truly pays to use your best bottle.

Ingredients

Makes about 500 g, enough for four to six people as part of a meze. You will need:

• 500 g Greek strained yoghurt, full-fat (10% fat is ideal for a rich result)
• 1 large cucumber
• 2 to 3 garlic cloves, finely grated or crushed to a paste
• 2 tablespoons extra virgin olive oil, plus extra for drizzling
• 1 tablespoon red wine vinegar (or the juice of half a lemon)
• 1 tablespoon finely chopped fresh dill or mint (optional)
• Sea salt, to taste

Of these, the olive oil is the one worth buying well, since its flavour sits right at the front of every mouthful.

How to make tzatziki

1. Grate the cucumber. Wash the cucumber and coarsely grate it, skin and all, into a bowl. There is no need to peel it — the skin adds a fresh green colour and a little texture.
2. Salt and drain. Toss the grated cucumber with a good pinch of salt and leave it in a sieve for 10 to 15 minutes. The salt draws out the water that would otherwise make your tzatziki runny.
3. Squeeze it dry. Tip the cucumber into a clean tea towel or a piece of muslin and wring it out firmly over the sink. You want it as dry as you can manage — this single step is the secret to a thick dip.
4. Prepare the garlic. Grate or crush the garlic to a smooth paste. Starting with two cloves is wise; you can always add more once everything is combined.
5. Build the base. In a large bowl, stir together the yoghurt, olive oil and vinegar until glossy and smooth. Whisking the oil in at this stage gives the dip its silky body.
6. Fold in the aromatics. Add the drained cucumber, the garlic paste and the dill. Fold everything together gently rather than beating it, so the tzatziki stays thick.
7. Season and rest. Taste and adjust with salt, and a little more vinegar or garlic if you like. Cover and chill for at least an hour so the flavours settle. Just before serving, spoon it into a bowl, make a small well in the top and finish with a generous drizzle of olive oil.

Tips for the best tzatziki

Drain twice if you have time. If your yoghurt is not already thick, let it drain in a lined sieve for an hour alongside the cucumber. The drier both are, the more luxurious the result.

Let the garlic mellow. Raw garlic is at its sharpest the moment it is grated. An hour or two in the fridge tames it into something warm and rounded, so tzatziki almost always tastes better the next day.

Pound, do not just chop. Crushing the garlic with a little salt in an olive wood mortar and pestle releases its oils far more evenly than a knife, giving a smoother flavour throughout the dip.

Finish at the table. Keep back some of your best oil for the final drizzle. Its aroma is strongest the instant it meets the cool yoghurt, so pour it just before the bowl leaves the kitchen.

How to serve tzatziki

Tzatziki is endlessly versatile. Serve it as a dip with warm pita, crusty bread or raw vegetables; spoon it alongside grilled souvlaki, gyros, lamb or chicken; or use it to cool down fried courgettes, aubergines and potatoes. It is also a natural centrepiece for a meze table, sitting happily next to olives, feta and a good loaf. However you serve it, a final drizzle of extra virgin olive oil ties the whole plate together.

Frequently asked questions

Why is my tzatziki watery?

Almost always because the cucumber was not drained enough. Salt it, let it sit, then squeeze out as much liquid as you can before mixing. Using thick strained yoghurt rather than a thinner set yoghurt also helps keep the dip firm.

Can I make tzatziki ahead of time?

Yes, and it is often better for it. Made a day in advance and kept covered in the fridge, the garlic softens and the flavours meld. Give it a gentle stir and a fresh drizzle of olive oil before serving. It keeps well for up to three days.

What olive oil is best for tzatziki?

A fruity, peppery extra virgin olive oil, since its flavour is tasted directly rather than cooked away. A naturally cloudy, unfiltered oil like our extra virgin olive oil from the Peloponnese brings the buttery, aromatic character that makes traditional tzatziki sing.

Make it once with proper strained yoghurt and a good drizzle of olive oil, and shop-bought tubs will never tempt you again. That is the quiet pleasure of Greek cooking — a few honest ingredients, chosen with care and enjoyed slowly. Pour La Vie.
