Ingredients

Main Base

2 pounds 900g boneless, skinless chicken breasts or thighs (about 4 pieces): Thighs stay juicier, breasts work well if not overcooked.
1 tablespoon 15ml olive oil: Helps the sauce grip the chicken and promotes a golden finish.
½ teaspoon fine sea salt: Seasons the chicken before the sauce goes on.
¼ teaspoon black pepper: Adds a mild background heat.

Tzatziki Sauce

1 cup 240g full-fat plain Greek yogurt: Full-fat creates a richer, creamier coating that doesn’t separate in the oven.
½ medium cucumber grated and squeezed dry (about ⅓ cup / 80g after squeezing): Removing excess water prevents a watery sauce and concentrates the cucumber flavor.
3 cloves garlic finely minced: Garlic is the backbone of classic tzatziki; don’t reduce it.
2 tablespoons 30ml fresh lemon juice: Brightens the whole dish and balances the richness of the yogurt.
1 tablespoon 15ml olive oil: Emulsifies the sauce and adds a silky mouthfeel.
1 tablespoon fresh dill finely chopped (or 1 teaspoon dried dill): Dill is the signature herb of tzatziki; fresh is best but dried works fine.
1 tablespoon fresh mint finely chopped (optional): Adds a cool, refreshing layer that lifts the sauce.
½ teaspoon salt: Seasons the sauce itself so it doesn’t taste flat.
¼ teaspoon black pepper: Rounds out the flavor.

Toppings and Garnish

¼ cup 40g crumbled feta cheese: Adds a salty, tangy contrast against the creamy sauce.
1 tablespoon fresh dill or flat-leaf parsley chopped: Makes the finished dish look Pinterest-worthy and fresh.
4 –5 thin lemon slices: For serving; a squeeze of fresh lemon right before eating lifts everything.

Optional Add-ins (Bake Alongside the Chicken)

1 cup 150g cherry tomatoes, halved: They burst and create a sweet, juicy element in the pan.
½ red onion sliced thin: Caramelizes beautifully around the edges.
1 medium zucchini sliced into rounds: Absorbs the tzatziki sauce and becomes silky.
⅓ cup 60g Kalamata olives, pitted: Adds a salty, briny depth to the whole dish.

Method

Set your oven to 400°F (200°C). Lightly grease a 9×13-inch (23x33cm) baking dish with olive oil or nonstick spray.
Grate the cucumber using a box grater. Place it in a clean kitchen towel or several layers of paper towel and squeeze firmly until almost no water comes out. This step matters more than it sounds. Wet cucumber makes the sauce runny and prevents the golden crust from forming.
In a medium bowl, combine the Greek yogurt, squeezed cucumber, minced garlic, lemon juice, olive oil, dill, mint (if using), salt, and pepper. Stir until smooth and well combined. Taste it. The sauce should be tangy, garlicky, and bright. Adjust lemon or salt if needed.
Pat the chicken pieces dry with paper towels. This helps the sauce stick better and promotes browning. Place the chicken in the prepared baking dish. Drizzle with 1 tablespoon olive oil and season with ½ teaspoon salt and ¼ teaspoon black pepper. If using optional vegetables, tuck them around the chicken pieces now.
Spoon the tzatziki sauce over each piece of chicken. Use the back of a spoon to spread it into a thick, even layer that fully covers the top and sides. Don’t be shy here. The more sauce, the better the results.
Place the dish uncovered in the preheated oven. Bake for 38–40 minutes for chicken breasts, or 35–38 minutes for thighs. The chicken is done when the internal temperature reads 165°F (74°C) on an instant-read thermometer and the edges of the sauce turn slightly golden with a few darker, charred spots on top. Those spots are flavor, not burning.
Remove from the oven. Scatter crumbled feta over the top immediately so it softens slightly from the residual heat. Let the dish rest for 5 full minutes before serving. This short rest allows the juices to redistribute back into the meat.
Finish with fresh dill or parsley and a few lemon slices on the side. Serve directly from the baking dish.
