Best Homemade Tzatziki Sauce
Why You’ll Love This Recipe
I have a strong memory of the first time I tried to make tzatziki. I was so excited to serve it with my lamb gyros, but when I pulled it out of the fridge, it looked like a sad, watery soup. The flavor was okay, but the texture was all wrong. It was a total flop.
That failure taught me the most important lesson about making the Best Homemade Tzatziki Sauce. It is all about the prep work. You absolutely cannot skip the step of drawing the water out of the cucumbers. If you do, your sauce will be thin and sad.
This recipe is my perfected version. It is thick, creamy, and packed with a punch of garlic and fresh dill. It is the kind of sauce that makes you want to eat it with a spoon. The key is using full-fat Greek yogurt. You can learn more about the straining process for yogurt on Wikipedia’s page on strained yogurt. It is a game changer for texture.
This Best Homemade Tzatziki Sauce solves the watery problem for good. It is the perfect dip for a hot summer day. My family fights over the last spoonful every single time.
Ingredients
- 1 large English cucumber (or 2 Persian cucumbers)
- 1 teaspoon kosher salt, divided
- 2 cups full-fat plain Greek yogurt
- 2 tablespoons fresh lemon juice
- 2 tablespoons extra-virgin olive oil
- 2 large cloves garlic, finely grated or minced
- 2 tablespoons fresh dill, finely chopped (plus more for garnish)
- 1 tablespoon fresh mint, finely chopped (optional, but recommended)
- Freshly ground black pepper, to taste
Step-by-Step Directions
- Start with the cucumber. Grate it using the large holes of a box grater. You want it to look like a fluffy pile of green snow. Do not peel it first, the skin adds color and texture.
- This is the most critical step. Put the grated cucumber into a clean kitchen towel or a piece of cheesecloth. Sprinkle it with 1/2 teaspoon of the kosher salt. Twist the towel tightly over the sink and squeeze with all your might. You will be shocked at how much liquid comes out. Keep squeezing until almost no more water drips out. This is the secret to a non-watery sauce.
- In a medium bowl, combine the strained cucumber, the full-fat Greek yogurt, fresh lemon juice, and extra-virgin olive oil. Stir it all together until it is smooth and creamy.
- Add the grated garlic, fresh dill, and fresh mint if you are using it. Add the remaining 1/2 teaspoon of kosher salt and a few grinds of black pepper. Stir everything again until it is fully combined.
- Taste it. Does it need more salt? More lemon juice? A little more garlic? This is your chance to adjust the flavors to your liking.
- Cover the bowl with plastic wrap and put it in the fridge. This is the hardest part. You must let it rest for at least 30 minutes, but 2 hours is even better. The flavors need time to get to know each other. The Best Homemade Tzatziki Sauce will taste completely different after it has chilled.
- Before serving, give it one last stir. Drizzle a little olive oil on top and sprinkle with extra fresh dill and a pinch of black pepper. It is ready.
Pro Tips for Success
You must squeeze the cucumber until it is almost dry. I cannot stress this enough. If you skip this, your sauce will be watery and thin. The salt helps draw out the moisture, so do not skip that step either.
Use full-fat Greek yogurt. Low-fat or non-fat yogurt has a higher water content and will make your sauce runny. The fat is also what makes the sauce so luscious and creamy. For more on the science of yogurt, you can check out this Wikipedia article on yogurt.
Let the sauce rest in the fridge. This is not a suggestion, it is a requirement. The raw garlic flavor will mellow out and the dill will infuse the entire sauce. It goes from good to incredible after a few hours.
Servings and Timing
This recipe makes about 2 cups of the Best Homemade Tzatziki Sauce. The active prep time is only about 15 minutes. You will need at least 30 minutes of inactive resting time in the fridge, but 2 hours is ideal for the best flavor. It serves about 8 people as a dip or condiment.
Variations and Substitutions
If you do not have fresh dill, you can use 2 teaspoons of dried dill. It will not be quite as bright, but it will still be good. You can also swap the dill for fresh mint entirely for a very different, but equally delicious, flavor profile.
For a vegan version, substitute the Greek yogurt with a thick, plain coconut or soy yogurt. You will still need to strain the cucumber. The flavor will be different, but it can still be a wonderful sauce.
If you want a little heat, add a pinch of cayenne pepper or a finely minced jalapeno. Some people love a little lemon zest in their sauce for extra brightness. This Best Homemade Tzatziki Sauce is very forgiving.
What to Serve With This
This sauce is a superstar. It is the perfect partner for so many dishes. I love to serve it with my crispy air fryer chicken gyros. The cool sauce is the perfect contrast to the warm, spiced chicken.
It also makes an incredible dip for roasted vegetables. Try it with my best crispy oven french fries. It is a million times better than ketchup. You can also use it as a spread for sandwiches or a dressing for a simple Greek salad.
Storage and Reheating
Store your Best Homemade Tzatziki Sauce in an airtight container in the refrigerator. It will stay fresh for up to 4 days. The flavors will actually continue to develop and get even better on the second day.
Do not freeze this sauce. The yogurt will separate and become grainy and watery when thawed. You also do not need to reheat it. It is always served cold.
If you see a little bit of liquid pooling on top after a day or two, just stir it back in. That is normal. If there is a lot of liquid, it means you did not squeeze the cucumber well enough.
FAQs
What is the best yogurt to use for tzatziki?
You must use full-fat plain Greek yogurt. It is thick and creamy. Do not use regular yogurt or non-fat yogurt, they are too watery and will ruin the texture of the sauce.
Can I use dried dill instead of fresh?
Yes, you can. Use about 2 teaspoons of dried dill for this recipe. The flavor will be less bright and more earthy, but it will still be a good sauce. Fresh dill is always better if you have it.
Why did my tzatziki turn out watery?
This is the most common problem. You did not squeeze enough water out of the cucumber. You must be very aggressive with the squeezing. Also, make sure you are using full-fat yogurt. Low-fat yogurt has more water.
Can I make this sauce without a garlic press?
Absolutely. The best way to get a smooth garlic flavor without big chunks is to grate the garlic on a Microplane or the small holes of a box grater. You can also mince it very finely with a sharp knife.
My tzatziki tastes too garlicky. What did I do wrong?
The raw garlic flavor will mellow out significantly after a few hours in the fridge. If it is still too strong after resting, you can stir in a little more yogurt or a squeeze of lemon juice to balance it out. Next time, use one small clove instead of two large ones.
Conclusion
Making this Best Homemade Tzatziki Sauce at home is so much better than anything you can buy at the store. It is fresher, creamier, and you can control exactly what goes into it. The most important thing is to not be afraid of the squeezing step. It is the only thing standing between you and a perfect sauce.
I hope you give this recipe a try. Let me know how it turns out for you. I am sure it will become a staple in your kitchen just like it is in mine.
