You think you know this dish? Sit down. Let me show you. Tzatziki Sauce is one of those things that looks simple until you make a bad version and then you understand exactly why a dish with four ingredients requires technique. Watery tzatziki is not tzatziki. Tzatziki without enough garlic is also not tzatziki. The thick, cold, garlicky, deeply refreshing Greek yogurt sauce that accompanies grilled lamb, souvlaki, pita, and practically everything on a Greek table — that’s the target.
Sauces are where the magic happens, and tzatziki is proof of that principle in 15 minutes. I learned my technique from a Greek prep cook named Yianni who I worked with in 2001 — specifically, he showed me the difference between strained Greek yogurt and squeezed cucumber, and what the combination produces versus the untreated versions. The cucumber has to be salted and squeezed. The yogurt has to be full-fat and thick. That’s it. Those two things are the whole technique.
This best homemade tzatziki sauce recipe uses the traditional approach: full-fat Greek yogurt, cucumber properly salted and drained, fresh dill, garlic, lemon, and good olive oil. It’s ready in 20 minutes and tastes better the next day. Make it ahead. It earns its rest time.
Why This Tzatziki Works
- Salting and squeezing the cucumber is non-negotiable — cucumber is mostly water. Unsqueezed cucumber turns tzatziki into soup within 30 minutes of mixing. Salt draws out the water, squeezing removes it. Ten minutes of patience produces a sauce that holds its texture for days.
- Full-fat Greek yogurt is the base — low-fat Greek yogurt is thinner and less rich. Regular yogurt (not Greek) produces a soup rather than a sauce. Full-fat, strained Greek yogurt is the only appropriate base.
- Fresh garlic, properly treated — raw garlic grated fine distributes evenly; roughly minced leaves chunks of pungent raw garlic. Grate it on a microplane or press it.
- Rest time integrates the flavors — fresh tzatziki has harsh garlic and unintegrated herb flavor. An hour of rest (or overnight) produces a harmonious, balanced sauce.

Ingredients for Tzatziki Sauce
Makes about 1.5 cups | Prep: 20 min | Rest: 1+ hour
The Tzatziki
- 1 cup full-fat Greek yogurt (Fage or similar thick-strained style)
- 1 English cucumber (or 2 Persian cucumbers)
- 1 teaspoon kosher salt (for sweating the cucumber)
- 2-3 cloves garlic, pressed or grated on a microplane
- 2 tablespoons fresh dill, finely chopped
- 1 tablespoon fresh mint (optional but traditional)
- 2 tablespoons fresh lemon juice
- 2 tablespoons extra virgin olive oil
- ½ teaspoon kosher salt (for seasoning the sauce)
- White pepper to taste
Serving
- Warm pita bread
- Sliced cucumber, radishes, carrots
- Drizzle of olive oil and fresh dill for garnish
How to Make Tzatziki Sauce
Step 1: Prepare the Cucumber
Grate the cucumber on the large holes of a box grater (or slice paper-thin and then chop finely). Place in a colander set over a bowl. Sprinkle with 1 teaspoon kosher salt and toss to coat. Let sit for 10 minutes — the salt draws moisture out of the cucumber. After 10 minutes, gather the cucumber in a clean kitchen towel or layers of cheesecloth and squeeze as hard as you can over the sink. Really squeeze — you’ll be surprised how much water comes out. Properly squeezed cucumber should look dry and feel almost pasty.
Step 2: Prepare the Garlic
Press the garlic or grate it very finely on a microplane. Rough mincing leaves pungent chunks. You want the garlic to distribute evenly throughout the yogurt so that every bite has a consistent, mellow garlic presence rather than random intense hits.
Step 3: Combine the Tzatziki
In a bowl, combine the Greek yogurt, squeezed cucumber, garlic, fresh dill, mint if using, lemon juice, and olive oil. Stir thoroughly to combine. Season with the additional ½ teaspoon salt and white pepper. Taste — it should be clearly tangy from the yogurt and lemon, clearly garlicky, and clearly herby from the dill.
Step 4: Rest in the Refrigerator
Cover and refrigerate for at least 1 hour before serving. Overnight is significantly better — the garlic mellows from sharp to savory, the dill infuses the yogurt, and everything integrates into a cohesive sauce rather than an assembly of individual flavors. This rest time is what separates good tzatziki from great tzatziki.
Step 5: Finish and Serve
Just before serving, taste again and adjust seasoning. Transfer to a serving bowl. Drizzle with extra virgin olive oil, scatter fresh dill fronds, and add a light dusting of paprika if desired. Serve cold with warm pita, grilled meats, or as a dip for vegetables.
Pro Tips for Better Tzatziki
- Squeeze the cucumber completely dry. This is the single most important step. If you don’t squeeze enough moisture out, the cucumber releases it into the yogurt and you’ll have watery tzatziki within an hour of making it. Squeeze until nothing more comes out.
- Full-fat Greek yogurt only. Low-fat is too thin; regular yogurt (not Greek/strained) is too thin. The thick, strained consistency of full-fat Greek yogurt is what gives tzatziki its body. Fage Total is the gold standard.
- Grate or press the garlic — don’t mince. Pressed or microplane-grated garlic distributes evenly through the sauce. Minced garlic creates inconsistent pockets of intensity.
- Rest overnight when possible. The difference between fresh tzatziki and day-old tzatziki is significant. Fresh garlic is pungent; rested garlic is mellow and savory. Plan ahead when you can.
- Taste the yogurt before you season. Different Greek yogurt brands have different levels of saltiness and acidity. Fage is more neutral; other brands can be quite salty already. Taste first, season accordingly.
Tzatziki Variations and Uses
- Classic Greek Plate: Serve alongside warm pita, olives, sliced tomato, and crumbled feta. Add grilled chicken or lamb for a full mezze spread.
- Tzatziki as a Sandwich Spread: Use in place of mayo on chicken sandwiches, wraps, or burgers. Especially good on grilled lamb burgers or chicken souvlaki wraps.
- Tzatziki Potato Salad: Replace mayo in potato salad with tzatziki for a Greek-inflected cold salad. Add cucumber, dill, red onion, and kalamata olives.
- Tzatziki Chicken Marinade: Marinate chicken thighs in tzatziki for 2-4 hours before grilling. The yogurt acid tenderizes and the garlic-dill flavor permeates the meat.
- Dip Table: Serve alongside classic hummus and a light tzatziki variation — see the connected recipe at tzatziki recipe for the related interpretation.
Storage Notes
- Refrigerator: 5-7 days in a sealed container. The flavor peaks on day 2-3. After day 5, the cucumber may release more moisture — simply drain or stir it back in.
- Freezer: Not recommended. Yogurt-based sauces separate and become grainy when frozen. Make fresh.
- Moisture management: If the tzatziki gets watery after storage (from residual cucumber moisture), drain off excess liquid and stir vigorously. Or add a tablespoon of fresh Greek yogurt and stir in to restore consistency.
Frequently Asked Questions
Why is my tzatziki watery?
The cucumber wasn’t squeezed dry enough. This is the most common tzatziki mistake. Go back to step 1 — grate the cucumber, salt it, let it sit 10 minutes, then squeeze it in a kitchen towel until absolutely nothing more comes out. If your tzatziki is already made and watery, drain off the excess liquid and add a tablespoon of fresh Greek yogurt.
What type of cucumber is best?
English cucumber or Persian cucumbers. Both have thinner skins, fewer seeds, and less water than regular slicing cucumbers. Regular cucumbers work but have more seeds that release more water. Peel and seed regular cucumbers before grating if using.
Dill vs. mint in tzatziki?
Both are traditional in different regional versions. Most widely known versions use dill as the primary herb, with mint as an optional addition. Greek tzatziki often uses both. Choose based on preference — dill is more pungent and herby, mint is brighter and more refreshing. Both are correct.
Can I use regular yogurt instead of Greek?
If you strain it first. Line a colander with cheesecloth or a coffee filter, add regular yogurt, and refrigerate for 4-8 hours until it’s thick like Greek yogurt. Use the strained yogurt. Regular unstrained yogurt produces a sauce that’s too thin to hold its shape.
