Tzatziki is a refreshing Greek sauce or dip made from thick yogurt, cucumber, garlic, olive oil, and fresh herbs. It’s a staple of Mediterranean cooking, prized for its cool, tangy flavor and creamy texture. This healthy version uses Greek yogurt and minimal oil, making it a light yet satisfying addition to grilled meats, vegetables, or pita bread.
Ingredients
- 1 large cucumber (about 12 oz / 340 g), peeled
- 1 teaspoon (5 g) salt, divided
- 2 cups (480 g) plain Greek yogurt (full-fat or 2%)
- 2 cloves garlic, minced or pressed
- 1 tablespoon (15 ml) extra-virgin olive oil, plus more for drizzling
- 1 tablespoon (15 ml) fresh lemon juice
- 1 tablespoon (3 g) fresh dill, chopped (or 1 teaspoon dried)
- 1 tablespoon (3 g) fresh mint, chopped (optional)
- Freshly ground black pepper, to taste
Instructions
- Grate the cucumber using a box grater or food processor. Place the grated cucumber in a clean kitchen towel or cheesecloth and squeeze firmly to remove as much liquid as possible. You should have about 1 cup (240 ml) of squeezed cucumber.
- In a medium bowl, toss the squeezed cucumber with 1/2 teaspoon of the salt. Let it sit for 10 minutes, then squeeze again to remove any additional water. This step ensures a thick, non-watery tzatziki.
- In a separate bowl, combine the Greek yogurt, minced garlic, olive oil, lemon juice, dill, and mint (if using). Stir until smooth.
- Add the squeezed cucumber and the remaining 1/2 teaspoon salt. Mix well. Season with black pepper to taste.
- Cover and refrigerate for at least 1 hour to allow the flavors to meld. Stir before serving.
- Serve chilled, drizzled with a little olive oil and extra herbs if desired.
Tips
- Squeeze the cucumber thoroughly: The more liquid you remove, the thicker and creamier your tzatziki will be. Skipping this step can make the dip watery.
- Use full-fat or 2% Greek yogurt: Non-fat yogurt can be tart and thin. If you prefer a lighter version, use 2% and add a tablespoon of plain regular yogurt to improve texture.
- Adjust garlic to taste: Raw garlic is potent. Start with one clove and add more if you like a stronger kick. For a milder flavor, let the garlic sit in the lemon juice for 5 minutes before mixing.
- Make it ahead: Tzatziki tastes even better after a few hours in the fridge. It’s perfect for meal prep.
Serving Suggestions
Serve tzatziki as a dip with fresh vegetables, pita bread, or pita chips. It’s also excellent as a sauce for grilled chicken, lamb, or beef souvlaki, and as a spread in gyros or wraps. For a lighter meal, spoon it over roasted vegetables or use it as a dressing for a Greek salad.
Variations
- Herb swap: Replace dill with fresh parsley or cilantro for a different flavor profile.
- Spicy tzatziki: Add a pinch of cayenne pepper or a finely chopped fresh chili for heat.
- Vegan tzatziki: Use a thick plant-based yogurt (like coconut or soy) and omit the honey if not using. The texture will be slightly less thick, but still delicious.
- Add feta: Crumble in 1/2 cup (75 g) of feta cheese for a richer, saltier dip.
Storage and Reheating
Store tzatziki in an airtight container in the refrigerator for up to 4 days. Stir well before serving, as some liquid may separate. Do not freeze, as the yogurt will become watery and grainy upon thawing. This dip is served cold, so no reheating is needed.
Frequently Asked Questions
Can I use regular yogurt instead of Greek?
Yes, but you’ll need to strain it first. Place regular yogurt in a cheesecloth-lined sieve over a bowl and refrigerate for 2 hours to remove excess whey. This will thicken it to a Greek-style consistency.
How do I make tzatziki thicker?
Ensure the cucumber is squeezed extremely well. You can also add a tablespoon of extra yogurt or a teaspoon of olive oil to help stabilize the mixture. Some people add a little cornstarch, but that’s not traditional.
Can I use dried herbs instead of fresh?
Yes, but use about one-third the amount. Dried dill or mint works well, but fresh herbs give a brighter flavor. If using dried, add them early to allow rehydration.
Is tzatziki gluten-free?
Yes, all the ingredients are naturally gluten-free. Just check that your yogurt is certified gluten-free if you have celiac disease.
Can I leave out the mint?
Absolutely. Mint is optional and adds a cool, slightly sweet note. If you don’t have it, simply omit it or add a bit more dill.
Why does my tzatziki taste bitter?
Bitterness can come from the olive oil (especially if it’s low-quality) or from over-mincing the garlic, which releases harsh compounds. Use a good extra-virgin olive oil and press or finely grate the garlic instead of crushing it.
