Tzatziki is the quintessential Greek sauce that brings cool, creamy refreshment to any Mediterranean meal. This traditional yogurt and cucumber sauce showcases the simplicity and elegance of Greek cuisine—fresh ingredients, quality Olive Oil, and aromatic herbs come together in perfect harmony.

Whether you're serving it with grilled meats, using it as a dip for warm pita bread, or dolloping it on gyros, homemade tzatziki is infinitely better than store-bought versions. This authentic recipe delivers the bold garlic flavor and fresh dill brightness that makes Greek tzatziki unforgettable.

What is Tzatziki?

Tzatziki (pronounced tsah-ZEE-kee) is a traditional Greek sauce made from strained yogurt, cucumber, garlic, olive oil, and fresh herbs—primarily dill. It's served cold as a condiment, dip, or sauce throughout Greece and the Mediterranean.

Origins and Tradition

While similar yogurt-based sauces exist throughout the Middle East and Mediterranean, Greek tzatziki is distinguished by its use of fresh dill and generous amounts of garlic. In Greece, it's served alongside nearly every meal, from casual taverna fare to elegant dinner parties.

Ingredients for Authentic Tzatziki

The beauty of tzatziki lies in its simplicity. Quality ingredients make all the difference:

Essential Ingredients

• 2 cups Greek yogurt (full-fat for best texture and authentic flavor)
• 1 large cucumber (English or Persian cucumbers work best)
• 3-4 cloves garlic (adjust to taste—Greeks love it garlicky!)
• 2 tablespoons fresh dill, finely chopped
• 2 tablespoons extra virgin olive oil
• 1 tablespoon fresh lemon juice
• 1 tablespoon white wine vinegar (optional, but traditional)
• 1/2 teaspoon sea salt (adjust to taste)
• 1/4 teaspoon freshly ground black pepper

Optional Additions

• 1 tablespoon fresh mint, finely chopped (for extra freshness)
• Pinch of cayenne pepper (for a subtle kick)
• 1 tablespoon fresh parsley (some regions add this)

Step-by-Step Instructions

Step 1: Prepare the Cucumber (Most Important Step!)

Grate the cucumber using the large holes of a box grater or a food processor with a grating attachment. Place the grated cucumber in a clean kitchen towel, cheesecloth, or fine-mesh strainer.

Squeeze firmly to remove as much liquid as possible. This step is crucial—excess moisture will make your tzatziki watery and dilute the flavors. You should extract at least 1/4 cup of liquid.

Pro Tips for Perfect Cucumber Prep:

• For even more moisture removal, salt the grated cucumber lightly and let it sit for 10 minutes before squeezing
• English cucumbers have fewer seeds and less water than regular cucumbers
• You can peel the cucumber if you prefer, but leaving some skin adds color and nutrients
• Squeeze in batches if needed—don't rush this step!

Step 2: Prepare the Garlic

Mince the garlic cloves very finely using a sharp knife, garlic press, or microplane grater. The finer you mince it, the more evenly it will distribute throughout the tzatziki.

Garlic Guidelines:

• Mild flavor: Use 2 cloves
• Traditional Greek: Use 3-4 cloves
• Extra bold: Use 5-6 cloves (for garlic lovers!)

Pro tip: Let the minced garlic sit for 5-10 minutes after chopping. This allows the allicin compounds to develop, creating more complex garlic flavor.

Step 3: Chop the Fresh Herbs

Remove any thick stems from the fresh dill and chop it finely. If using mint or parsley, chop those as well. Fresh herbs are absolutely essential—dried dill will not give you authentic tzatziki flavor.

Herb Tips:

• Wash and thoroughly dry herbs before chopping
• Use a sharp knife to prevent bruising
• Chop just before using for maximum freshness
• Save a small sprig of dill for garnish

Step 4: Combine the Base Ingredients

In a medium mixing bowl, add the Greek yogurt. Make sure you're using thick, strained Greek yogurt—regular yogurt is too thin and will make watery tzatziki.

Add the squeezed cucumber, minced garlic, and chopped herbs to the yogurt. Using a spoon or spatula, mix gently but thoroughly until all ingredients are evenly distributed.

Step 5: Add Olive Oil and Acid

Drizzle in the extra virgin olive oil, fresh lemon juice, and white wine vinegar (if using). The olive oil adds richness and authentic Greek flavor, while the acid brightens the sauce and balances the creamy yogurt.

Stir well to incorporate. The olive oil should emulsify slightly with the yogurt, creating a smooth, creamy texture.

Step 6: Season to Perfection

Add the salt and freshly ground black pepper. Start conservatively with 1/2 teaspoon of salt—you can always add more, but you can't take it away.

Taste and adjust seasonings. Remember that flavors will intensify as the tzatziki rests, so don't over-season initially.

Seasoning Balance:

• Too bland? Add more salt and lemon juice
• Too garlicky? Add more yogurt or a touch of honey
• Too thick? Thin with a tablespoon of water or lemon juice
• Not enough herb flavor? Add more fresh dill

Step 7: Chill and Rest (Don't Skip This!)

Cover the bowl tightly with plastic wrap or transfer to an airtight container. Refrigerate for at least 1 hour, preferably 2-4 hours.

This resting time is essential for several reasons:

• Flavors meld and develop complexity
• Garlic mellows slightly and distributes evenly
• Herbs infuse throughout the sauce
• Texture becomes creamier and more cohesive

Best practice: Tzatziki tastes even better the next day! Make it a day ahead for optimal flavor.

Step 8: Final Touches and Serving

Before serving, give the tzatziki a good stir. If any liquid has separated (this can happen), simply stir it back in.

Transfer to a serving bowl. Drizzle with a little extra virgin olive oil, garnish with a fresh dill sprig, and optionally sprinkle with a pinch of paprika or sumac for color.

Recipe Variations

Regional Greek Variations

Cretan-Style Tzatziki

Add 1-2 tablespoons of finely chopped walnuts for texture and richness.

Island-Style Tzatziki

Common Mistakes to Avoid

1. Not Draining the Cucumber Properly

This is the #1 mistake! Watery cucumber makes watery tzatziki. Always squeeze thoroughly.

2. Using Low-Fat or Regular Yogurt

Full-fat Greek yogurt is essential for authentic texture and richness. Low-fat versions make thin, bland tzatziki.

3. Using Dried Dill

Fresh dill is non-negotiable for authentic Greek tzatziki. Dried dill lacks the bright, fresh flavor that makes this sauce special.

4. Skipping the Resting Time

Serving tzatziki immediately means you miss out on the flavor development that happens during refrigeration.

5. Over-Salting Initially

Salt intensifies as the tzatziki sits. Start with less and adjust after resting.

6. Using Poor Quality Olive Oil

Since olive oil is a key flavor component, use high-quality extra virgin olive oil for best results.

Storage and Make-Ahead Tips

Refrigerator Storage

Store tzatziki in an airtight container in the refrigerator for 3-4 days. The flavors actually improve over the first 24 hours, making it perfect for meal prep.

Handling Separation

If liquid separates during storage, simply stir it back in before serving. This is normal and doesn't affect quality.

Make-Ahead Instructions

Tzatziki is ideal for making ahead:

• 1 day ahead: Optimal flavor development
• 2-3 days ahead: Still excellent, flavors fully melded
• 4 days: Maximum storage time

Freezing (Not Recommended)

Tzatziki doesn't freeze well due to the yogurt and cucumber. The texture becomes grainy and watery when thawed.

Tips from Greek Grandmothers (Yiayias)

Secret Techniques

• Grate garlic instead of mincing: Use a microplane for smoother distribution
• Add a pinch of sugar: Balances acidity if your yogurt is very tart
• Use day-old bread: Some yiayias add a small piece of stale bread to absorb excess moisture
• Chill the bowl: Place your serving bowl in the fridge before filling for extra-cold tzatziki
• Taste as you go: Adjust seasonings to your family's preferences

Frequently Asked Questions

Can I use regular yogurt instead of Greek yogurt?

Not recommended. Regular yogurt is too thin and will make watery tzatziki. If you must use it, strain it through cheesecloth for several hours first to remove excess whey.

Can I make tzatziki without a food processor?

Absolutely! A simple box grater works perfectly for the cucumber. This is actually the traditional method.

Why is my tzatziki watery?

The cucumber wasn't drained enough, or you used regular yogurt instead of Greek yogurt. Always squeeze the cucumber thoroughly.

Can I use dried dill?

No, fresh dill is essential for authentic flavor. Dried dill won't give you the same bright, vibrant taste.

How do I make tzatziki less garlicky?

Reduce the garlic to 1-2 cloves, or blanch the garlic cloves in boiling water for 30 seconds before mincing to mellow the flavor.

Is tzatziki keto-friendly?

Yes! Tzatziki is low in carbs and high in healthy fats, making it perfect for keto and low-carb diets.
