Tzatziki Sauce Recipe: Thick, Creamy, and Never Watery
The first time I made tzatziki sauce, I skipped the step where you squeeze the water out of the cucumber. I figured it was optional — how much water could one cucumber really hold? By the next morning, my “sauce” had turned into cucumber-flavored yogurt soup pooling at the bottom of the bowl.
This tzatziki sauce recipe fixes that specific problem, along with a few others that most recipes gloss over. You’ll find a real comparison of grating versus dicing the cucumber, lemon versus vinegar, and a dedicated section on why tzatziki sauce turns watery even when you think you did everything right. Whether you’re making this as a gyro sauce, a veggie dip, or a sandwich spread, this is the version that actually holds together in the fridge.
Quick Summary
This tzatziki sauce recipe combines grated and thoroughly drained cucumber with thick Greek yogurt, garlic, lemon juice, olive oil, and fresh dill. It takes about 15 minutes of hands-on prep, plus a short chill time to let the flavors meld. This recipe also covers a Grating vs. Dicing comparison, a Lemon vs. Vinegar comparison, and a dedicated troubleshooting section for watery or bland tzatziki.

What Is Tzatziki Sauce?
Tzatziki is a Greek sauce and dip made from strained yogurt, grated cucumber, garlic, olive oil, and usually lemon juice or vinegar, often finished with fresh dill or mint. It’s cool, tangy, and thick enough to hold its shape on a spoon rather than pour like a dressing. In Greece it’s traditionally made with strained sheep or goat’s milk yogurt, though full-fat Greek yogurt is the standard substitute most home cooks use today.
Ingredients
- 1 English cucumber (or 2 Persian cucumbers)
- 1 teaspoon kosher salt, divided
- 2 cups full-fat Greek yogurt
- 2 tablespoons extra-virgin olive oil, plus more for drizzling
- 1 tablespoon fresh lemon juice
- 2 to 3 garlic cloves, finely grated or minced
- 2 tablespoons chopped fresh dill
- Freshly ground black pepper, to taste
Tools You’ll Need
- Box grater
- Clean kitchen towel or cheesecloth
- Mixing bowl
- Garlic press or fine grater, for the garlic
How to Make Tzatziki Sauce, Step by Step
1. Grate and salt the cucumber. Grate the cucumber on the large holes of a box grater, skin on. Toss with 1/2 teaspoon of the salt and let it sit in a colander or on a towel for 10 minutes — this draws out extra moisture before you even start squeezing.
2. Squeeze out the water. Gather the grated cucumber in a clean kitchen towel and squeeze firmly over the sink until no more liquid comes out. This step matters more than any other ingredient in the recipe — don’t rush it.
3. Mix the yogurt base. In a mixing bowl, combine the Greek yogurt, olive oil, lemon juice, garlic, dill, the remaining 1/2 teaspoon salt, and black pepper. Stir until smooth.
4. Fold in the cucumber. Add the drained, squeezed cucumber to the yogurt mixture and stir to combine. Taste and adjust salt, lemon, or garlic as needed.
5. Chill before serving. Cover and refrigerate for at least 30 minutes, up to 2 hours, to let the flavors meld and the sauce firm up. Drizzle with more olive oil just before serving.
Grating vs. Dicing the Cucumber
Every tzatziki sauce recipe picks one method and doesn’t explain why. Here’s the actual difference:
| Method | Texture | Best For |
| Grating (this recipe) | Smooth, evenly distributed, releases more water | A classic dip or gyro sauce with a uniform texture |
| Dicing | Chunkier bite, more visible cucumber pieces, releases less water | A tzatziki dip you want to eat with a spoon or spread thick |
Grated cucumber blends more seamlessly into the yogurt and is easier to squeeze dry, which is why most recipes default to it. Diced cucumber holds more of its own texture and needs slightly less draining time since it releases less liquid overall, but it also means less of the yogurt base is directly infused with cucumber flavor.
Lemon Juice vs. Vinegar
Most tzatziki recipes use lemon juice, but a few authentic versions call for distilled white vinegar instead. Here’s how they compare:
| Acid | Flavor Profile | Best For |
| Lemon Juice (this recipe) | Brighter, slightly floral, rounds out the garlic | A fresher-tasting, everyday tzatziki sauce |
| White Vinegar | Sharper, more tangy, cuts through richness more assertively | A more traditional or tangier-leaning version |
Both work — the difference is subtle but noticeable side by side. If you only have vinegar on hand, substitute it 1:1 for the lemon juice in this recipe without changing anything else.
Why Is My Tzatziki Sauce Watery?
This is the single most common problem with homemade tzatziki, and it almost always comes down to one of these:
- Skipping the squeeze step. Grated cucumber is mostly water — even a quick squeeze isn’t enough. Wring it out in a towel until it feels noticeably dry and compact.
- Using low-fat or regular yogurt instead of thick Greek yogurt. Regular yogurt has a much higher water content and will never firm up the way strained Greek yogurt does.
- Not draining the yogurt itself. Occasionally Greek yogurt has a thin layer of liquid (whey) sitting on top in the container — stir it back in or pour it off before measuring, rather than mixing it into the sauce.
- Making it too far ahead without accounting for extra liquid release. Cucumber continues to release small amounts of moisture over time. If your tzatziki gets watery after a day or two in the fridge, just stir it or spoon off the excess liquid before serving.
Dill vs. Mint vs. Both
Dill is the most traditional herb in tzatziki sauce, giving it a cool, slightly grassy flavor. Mint is used in some regions and pairs especially well if you’re serving the sauce alongside spicier dishes. If you can’t decide, use half the amount of each — a tablespoon of chopped dill and a tablespoon of chopped mint gives you the best of both without either one taking over.
Variations to Try
Vegan Tzatziki
For a vegan tzatziki recipe, substitute the Greek yogurt with a thick, unsweetened coconut or cashew-based yogurt. Strain it in a cheesecloth for 30 minutes first if it’s thinner than dairy Greek yogurt, since plant-based yogurts vary widely in thickness.
Chicken Tzatziki
For a chicken tzatziki recipe, toss shredded or diced cooked chicken directly into the finished sauce for a quick, high-protein salad, or spoon the sauce generously over grilled chicken just before serving.
Dairy-Free Tzatziki
This dairy free tzatziki recipe uses the same coconut or cashew yogurt swap as the vegan version above — the technique for draining the cucumber stays exactly the same regardless of which yogurt base you use.
Tzatziki Without Cucumber
If you’re out of cucumber or want a tzatziki recipe without cucumber for a firmer dip, simply omit it and season the yogurt base a little more assertively with extra garlic, lemon, and herbs to make up for the missing freshness.
Tzatziki Without Dill
For a tzatziki recipe without dill, either leave the herbs out entirely for a cleaner garlic-and-lemon flavor, or substitute an equal amount of fresh mint or parsley.
Using Tzatziki as Gyro Sauce
This same recipe doubles as a greek gyro sauce with no changes needed — the thick, garlicky base is exactly what gyro wraps and doner kebabs are built around. Spoon it generously over the meat before wrapping, or serve it on the side for dipping.
Is Tzatziki Sauce Healthy?
Made with Greek yogurt, cucumber, and olive oil, tzatziki sauce is relatively low in calories and higher in protein than most creamy sauces or dressings — Greek yogurt alone has roughly four times the protein of sour cream per equal serving — largely because of the yogurt base. A standard 2-tablespoon serving comes in under 40 calories in this recipe. It’s not a significant source of any single nutrient, but as far as condiments go, it’s a lighter option than sour cream or mayonnaise-based sauces.
Common Mistakes to Avoid
- Using regular yogurt instead of Greek yogurt. The extra straining process Greek yogurt goes through is what gives tzatziki its signature thickness.
- Adding raw garlic right before serving. Garlic mellows and rounds out during the chill time — serving it immediately can leave a harsh, sharp bite.
- Over-salting before tasting the finished sauce. Salt levels compound once the cucumber and yogurt are combined — taste at the end, not just while seasoning each component.
- Skipping the chill time entirely. Even 30 minutes makes a noticeable difference in how the flavors come together compared to serving it immediately.
What to Serve With Tzatziki Sauce
Tzatziki sauce works as a dip for warm pita and fresh vegetables, a sauce for gyros, kebabs, and souvlaki, a spread for sandwiches and wraps, or a topping for grilled chicken, lamb, or salmon.

Storage
Store tzatziki sauce in an airtight container in the refrigerator for up to 4 days. Stir before serving if any liquid has separated on top. This sauce is not recommended for freezing, since the texture of both the yogurt and cucumber changes significantly once thawed.
Frequently Asked Questions
What is tzatziki sauce made of?
Tzatziki sauce is made of strained yogurt, grated or diced cucumber, garlic, olive oil, and either lemon juice or vinegar, typically finished with fresh dill or mint.
How to make tzatziki sauce ahead of time?
Tzatziki sauce actually improves with a little time in the fridge, so making it up to a day ahead works well. Just give it a stir before serving, since a small amount of liquid can separate as it sits.
What is a good substitute for dill in tzatziki?
Fresh mint or fresh parsley both work well as a dill substitute, though the flavor will lean slightly different — mint adds a cooler, brighter note, while parsley keeps things more neutral.
Is tzatziki sauce the same as gyro sauce?
Yes, tzatziki is the traditional Greek sauce used on gyros — there’s no separate “gyro sauce” recipe, it’s the same cucumber-yogurt sauce used for dipping, spreading, and topping.
Can I make tzatziki sauce without cucumber?
Yes, though it will taste noticeably different since cucumber is what gives tzatziki its signature freshness. See the Variations section above for how to adjust the seasoning if you leave it out.
