Simple ingredients, proper technique. That’s the whole game. Tzatziki Sauce — Greek yogurt, cucumber, garlic, dill, lemon — is one of those condiments that seems like it shouldn’t require a recipe. Five ingredients, mix them together, done. Except the version that comes together in sixty seconds tastes fine. The version built with technique — properly strained yogurt, thoroughly wrung cucumber, rested overnight — tastes like something you’d pay twelve dollars for at a restaurant and then try to figure out the recipe on the drive home. The difference between those two versions is what this recipe is about.
Real tzatziki should be thick enough to hold a spoon straight up. The cucumber should add texture, not water. The garlic should be present without being aggressive. And the lemon should brighten every bite without turning the sauce thin. These things don’t happen by accident. They happen when you respect the technique.
Why This Tzatziki Works
- Strained yogurt: Greek yogurt already has much of the whey removed, but straining through cheesecloth for an hour produces an even thicker, creamier base. Worth the time.
- Grated and wrung cucumber: Cucumber is 95% water. Salting and squeezing the grated cucumber removes the liquid that would otherwise water down the entire sauce within minutes.
- Garlic paste, not minced: Crushing garlic to a smooth paste with salt distributes it evenly throughout the sauce and tames the sharpness slightly. Minced garlic chunks create uneven heat distribution.
- Olive oil: A generous drizzle of good olive oil adds richness and rounds out the acidity of the yogurt and lemon.
- Resting overnight: The garlic mellows, the dill infuses, and the cucumber flavor permeates the yogurt base. Overnight tzatziki is substantially more complex than same-day tzatziki.
Ingredients
Tzatziki Sauce
- 2 cups full-fat Greek yogurt (10% fat preferred)
- 1 English cucumber (or 2 Persian cucumbers), grated
- 2 garlic cloves, minced to a paste with salt
- 2 tbsp fresh dill, finely chopped (or 1 tsp dried)
- 1 tbsp fresh mint, finely chopped (optional but traditional)
- 2 tbsp fresh lemon juice
- 2 tbsp extra virgin olive oil (plus more for serving)
- ½ tsp salt (or to taste)
- White pepper to taste
Instructions
Step 1: Drain the Cucumber
Grate cucumber on the large holes of a box grater. Place grated cucumber in a clean kitchen towel or several layers of cheesecloth. Sprinkle with a pinch of salt, toss briefly, and let sit 5 minutes. Then gather the towel and squeeze as hard as possible, wringing out all liquid. Twist and squeeze until no more liquid comes out. A standard cucumber releases a shocking amount of water — removing it all is essential for a thick sauce.
Step 2: Prepare the Garlic
Place the minced garlic on a cutting board with a small pinch of salt. Using the flat side of a large knife, mash and smear the garlic against the board repeatedly until it becomes a smooth, almost paste-like consistency. The salt acts as an abrasive that helps break down the garlic cell walls. This paste distributes evenly and has a less aggressive bite than simple minced garlic.
Step 3: Combine Everything
In a bowl, combine the Greek yogurt, wrung cucumber, garlic paste, fresh dill, mint if using, lemon juice, olive oil, salt, and white pepper. Stir to combine thoroughly. Taste and adjust — more lemon for brightness, more salt if it tastes flat, more garlic if it needs more punch. The sauce should taste assertive and bright at this stage — it mellows and rounds out during the resting period.
Step 4: Rest and Serve
Cover and refrigerate at least 2 hours, overnight for best flavor. Before serving, drizzle the top generously with olive oil and add a few sprigs of fresh dill or a pinch of dried dill for garnish. Serve from the refrigerator — tzatziki is excellent cold, unlike chimichurri or pesto that benefit from room temperature.
Tips and Common Mistakes
- Watery tzatziki: Almost always from insufficient cucumber wringing. Squeeze until it looks like there’s absolutely nothing left to squeeze, then squeeze one more time. The difference between “squeezed” and “fully wrung” is significant.
- Too much garlic: Raw garlic intensifies over time in the refrigerator. Two cloves is a good starting point. If you love garlic, use three — but taste carefully after resting, especially if making a day ahead.
- Low-fat yogurt: Produces a thinner, less rich sauce. The fat in Greek yogurt is what creates the characteristic thick, creamy, luxurious texture. Use full-fat whenever possible.
- Dried dill only: Fresh dill transforms tzatziki. Dried dill works and is traditional in some recipes, but fresh dill’s bright, anise-adjacent quality is noticeably superior in a cold sauce. Worth seeking out.
- Immediate serving: Same-day tzatziki tastes fine. Next-day tzatziki tastes exceptional. The patience is worth it — plan ahead.
Variations
- Thick dip version: Strain the yogurt through cheesecloth in the refrigerator for 2–3 hours before making the sauce. This removes even more whey and produces an extremely thick, spreadable dip that holds its shape.
- Yogurt sauce with cumin: Add a quarter teaspoon of toasted cumin and a tablespoon of tahini. Middle Eastern-inspired, excellent with falafel and shawarma.
- No-cucumber version: Skip the cucumber for a straight garlic-herb yogurt sauce. Works as a marinade, sauce for roasted vegetables, or drizzle for grain bowls.
- Avocado tzatziki: Blend in one ripe avocado. Bright green, slightly richer, and very popular. Use within 24 hours before oxidation affects the color.
Tzatziki belongs on the same table as the Classic Hummus from Scratch, the Crispy Falafel, and the Restaurant-Style Guacamole. Pair with the Salsa Verde for a condiment spread that covers every cuisine at once.
Storage
- Refrigerator: Keeps for 4–5 days. The flavor peaks between 24 and 48 hours after making. After 5 days the cucumber starts to weep even more liquid and the texture suffers.
- If it weeps: Normal for tzatziki to release a small amount of liquid as it sits. Pour off the liquid (or drain through a strainer briefly) and stir the sauce back together before serving.
- Freezer: Not recommended. Yogurt separates on thawing and the sauce becomes grainy and watery.
Frequently Asked Questions
Can I use regular yogurt instead of Greek yogurt?
Yes, but strain it first. Line a colander with cheesecloth, add the yogurt, and refrigerate 2–3 hours until thickened. The result won’t be quite as rich as commercial Greek yogurt but will work well. Full-fat plain yogurt is essential — low-fat versions have too much water to drain properly.
What’s the difference between tzatziki and raita?
Both are yogurt-based condiments with cucumber. Greek tzatziki uses dill and garlic as primary flavorings. Indian raita is seasoned with cumin, often coriander, and sometimes mint — no dill, different spice profile entirely. Both serve similar cooling functions alongside their respective cuisines but are distinct sauces.
Should I use fresh or dried dill?
Fresh for the best flavor. Dried dill is acceptable and traditional in some recipes. If using dried, use half the quantity — dried dill is more concentrated. Add it with the other dry seasonings and allow the full resting time for the flavor to develop.
What do you serve tzatziki with besides pita?
Grilled chicken and lamb are the natural pairings. Tzatziki also works as a sauce for gyros and souvlaki, a dip for fresh vegetables, a spread for burgers and wraps, and drizzled over roasted potatoes. It’s one of the most versatile condiments in the repertoire.
