A 30-minute marinade is enough to make the chicken noticeably more tender, lemon juice works fast. But the real trick to souvlaki that tastes like it came off a Greek street cart is the grill temperature.
Too high and you’ll char the outside before the interior is done; too low and you’ll dry it out. Medium heat, a clean grate, and patience turning the skewers every few minutes gives you juicy, caramelized meat. This greek chicken souvlaki with tzatziki sauce pairs that charred chicken with a thick, cooling sauce that won’t water down on the plate, if you squeeze the cucumber well.
The contrast is sharp and refreshing.
I once served souvlaki with tzatziki that pooled like milk on the plate, my guests politely dabbed it up with pita.
Why does marinating chicken in lemon juice and oregano matter?
Lemon juice is the key. Its acid gently breaks down the chicken’s proteins, making the meat noticeably more tender after just 30 minutes. You’ll feel the difference when you cut into the cooked meat, it’s supple, not tough.
Oregano brings that unmistakable Greek aroma; it’s assertive but not harsh, and it lingers on the grill. The olive oil carries both flavors into every bite. Without the acid, the chicken would be firmer and less flavorful.
A short marinade is enough because the acid works fast, any longer and the texture could become cottony. You want the surface to taste bright and herbaceous, and that’s exactly what this mix delivers.
The real trick to thick, creamy tzatziki
It’s all about the cucumber. Grate it on the large holes of a box grater, then squeeze the living water out. Now I squeeze the grated cucumber in a clean kitchen towel until no more water drips out, and my tzatziki stays thick enough to spoon.
That step prevents a watery mess. Full-fat Greek yogurt gives you a tangy, rich base that holds its own against the garlic and dill. The lemon juice brightens everything without making it runny.
If you skip the squeeze, you’ll watch the sauce thin out on the plate. You want a dollop that stays put, not a puddle.
Why medium heat on the grill works better than high heat
High heat charrs the outside before the inside is cooked. Medium heat lets the chicken cook through evenly, 10 to 12 minutes total, turning a few times. The pieces are bite-sized, so they cook fast.
You get a nice char on the edges from the oil and marinade, but the center stays juicy. If you crowd the grill, the temperature drops and you lose that browning. Work in batches if needed.
The result is chicken that’s caramelized on the outside and still moist inside. That’s what you want from a souvlaki skewer.

What to look for with these ingredients
Greek yogurt: Use full-fat Greek yogurt. Nonfat will make the tzatziki thin and watery.
Cucumber: Grate on large holes then squeeze dry in a towel. That’s the only way to avoid a watery sauce.
Fresh dill: Use fresh dill, not dried. Dried dill has a muted flavor and a different texture.
Lemon juice: Fresh squeezed is noticeably brighter. Bottled juice tastes flat and can be more acidic.
How to get juicy, charred chicken and thick tzatziki every time
Marinate the chicken
Whisk lemon juice, olive oil, garlic, oregano, salt, and pepper. Coat chicken breasts fully, cover, and let sit at least 30 minutes. The meat will feel slightly firmer on the surface after marinating, not slimy.
Prep the tzatziki
Grate cucumber on large holes of a box grater. Squeeze handfuls in a towel until no more water drips out. Stir with yogurt, dill, garlic, lemon juice, and salt.
Chill until serving. The sauce should be thick enough to hold a spoon upright.
Cut and skewer the chicken
Cut marinated chicken into bite-sized pieces, about 1-inch cubes. Thread onto skewers, leaving a small gap between pieces for even cooking. The pieces should feel uniform in size so they finish at the same time.
Grill over medium heat
Preheat grill to medium. Place skewers on grates and cook 10 to 12 minutes, turning every 2 to 3 minutes.
You want a golden-brown char on edges but no blackening. Chicken should feel firm to the touch and juices run clear.
Check for doneness
Cut into one piece to check. The interior should be white throughout, not pink, and the meat should be moist, not dry. If it’s still translucent in the center, give it another minute per side.
Greek Chicken Souvlaki with Tzatziki Sauce

Instructions
Chicken Skewers
Marinate the Chicken:
Combine 1/4 cup lemon juice, 1/4 cup olive oil, 4 minced garlic cloves, 2 teaspoons dried oregano, 1 teaspoon salt, and 1/2 teaspoon black pepper in a bowl. Thoroughly coat the chicken breasts, cover, and allow to marinate for at least 30 minutes.Make Tzatziki Sauce:
Grate the cucumber finely, press out excess moisture, then mix with Greek yogurt, 2 tablespoons chopped fresh dill, 1 minced garlic clove, 1 tablespoon lemon juice, and a pinch of salt. Refrigerate while the chicken cooks.
Tzatziki
Grill Chicken Skewers:
Slice the marinated chicken into bite-sized cubes and thread onto skewers. Grill over medium heat for 10–12 minutes, turning every so often, until browned and fully cooked.Serve with Tzatziki:
Serve the chicken skewers with a generous spoonful of tzatziki. Garnish with additional dill or a lemon wedge if desired.
3 Swaps That Work (and 1 That Doesn’t) for This Souvlaki
chicken breasts: boneless skinless chicken thighs. Thighs are juicier and more forgiving on the grill.
They take the same 10 to 12 minutes over medium heat. The meat stays moist even if you leave it a minute too long. Breasts work fine, but thighs give you a little more insurance against dryness.
Greek yogurt: full-fat sour cream or labneh. Sour cream thins the tzatziki slightly but keeps it tangy.
Labneh is thicker and closer to yogurt. Both need the same cucumber squeeze. Avoid nonfat Greek yogurt, it turns watery.
Start with the same 1 cup the recipe uses, then adjust thickness with a spoonful more if needed.
fresh dill: dried dill (1 teaspoon for the 2 tablespoons fresh). Dried dill is milder and more concentrated. Use one-third the amount.
The tzatziki will taste less bright, more earthy. Stir it in and taste before adding more.
If fresh isn’t an option, mint also works, use 1 tablespoon minced, for a different but still fresh finish.
lemon juice: white wine vinegar or red wine vinegar. Vinegar works in the marinade but changes the flavor profile.
It’s more pungent, less floral. In the tzatziki, skip it, lemon’s acidity is cleaner. If you must, use half the amount and taste.
The swap won’t ruin anything, but the dish loses that Greek brightness.
Storing Leftover Souvlaki and Tzatziki
Store leftover chicken and tzatziki separately in airtight containers. The chicken keeps in the fridge for up to 3 days. Reheat gently on the stovetop or in a low oven to avoid drying it out; microwaving can make it tough.
The tzatziki will thin slightly as the cucumber releases more moisture over time, but it stays flavorful for 2 to 3 days. Stir it well before serving. For the best texture, eat the assembled dish within an hour of grilling; the warm chicken and cool sauce contrast is at its peak.
If you’re making ahead, grill the chicken and prep the tzatziki separately, then combine just before serving. Freezing the chicken works for up to 1 month, but the tzatziki does not freeze well due to the yogurt and cucumber. Thaw the chicken in the fridge and reheat before serving.
Tips
- Soak wooden skewers in water for at least 30 minutes before threading the chicken. This prevents the exposed ends from charring and breaking on the grill, which can cause pieces to fall into the coals.
- Pat the chicken pieces dry with paper towels after marinating and before skewering. Excess moisture on the surface will steam instead of sear, preventing the golden-brown char you want from the medium heat.
Frequently Asked Questions
Can I make the tzatziki a day ahead?
Yes, and it stays thick for 2 to 3 days if you squeezed the cucumber well. The flavor actually mellows overnight.
Stir it before serving, it will have thinned slightly as the cucumber releases more moisture. Don’t freeze it; yogurt breaks down.
How do I prevent the chicken from sticking to the grill?
Start with a clean, oiled grill grate and medium heat. The oil in the marinade helps, but if the chicken still sticks, it’s not ready to turn, give it another minute. A good char releases naturally.
Avoid prying; you’ll tear the meat.
What’s the best way to serve souvlaki besides skewers?
Slide the chicken off the skewers onto a warm platter. Spoon tzatziki over the top or serve it on the side.
Pita, chopped tomatoes, and sliced red onion make a quick plate. The chicken stays juicy when you don’t stack it.
Can I use chicken thighs instead of breasts?
Yes, and thighs are more forgiving, they stay moist even if you leave them a minute too long. Cut them into the same 1-inch cubes and grill over medium heat for the same 10 to 12 minutes. You’ll see juices run clear when they’re done.
How do I know when the chicken is fully cooked?
Cut into the thickest piece, the interior should be white throughout with no pink. The meat feels firm to the touch, and juices run clear. After 10 to 12 minutes over medium heat, that’s your cue.
If it’s still translucent, give it another minute per side.
