# Instructions:
01 -
Preheat your oven to 400°F and lightly grease a 9x13-inch baking dish with cooking spray or a thin layer of olive oil. Having your dish ready before assembling this Easy Dump and Bake Chicken Tzatziki Casserole keeps the process quick and seamless.
02 -
In a large bowl, toss 2 lbs of boneless, skinless chicken thigh chunks with 2 tbsp olive oil, 1 tsp dried oregano, 1/2 tsp garlic powder, 1/2 tsp onion powder, and salt and pepper to taste. Coat every piece evenly so the chicken is fully flavored before baking.
03 -
In a separate bowl, stir together 1 1/2 cups plain whole-milk Greek yogurt, 1 cup grated and squeezed-dry cucumber, 3 cloves minced garlic, 2 tbsp fresh lemon juice, and 1 tbsp chopped fresh dill until smooth and well combined. This creamy tzatziki sauce base is the heart of the casserole.
04 -
Scatter 1 medium zucchini sliced into 1/4-inch rounds, 1/2 red onion thinly sliced, 1 cup halved cherry tomatoes, and 1/2 cup pitted and halved Kalamata olives evenly across the bottom of your prepared baking dish to create a hearty Mediterranean vegetable base.
05 -
Place the seasoned chicken thigh chunks on top of the vegetables, then pour and spread the tzatziki sauce mixture evenly over everything. This is the signature dump-and-bake step that makes this Easy Dump and Bake Chicken Tzatziki Casserole so effortless and weeknight-friendly.
06 -
Sprinkle 3/4 cup crumbled feta cheese generously over the top of the casserole. Drizzle with 1 tbsp olive oil and finish with 1 tsp dried oregano. This golden feta finish will bubble and lightly brown in the oven, adding incredible savory flavor and texture.
07 -
Bake your Easy Dump and Bake Chicken Tzatziki Casserole uncovered at 400°F for 40–45 minutes, until the chicken is cooked through to an internal temperature of 165°F and the feta is golden and slightly crispy around the edges. The sauce will thicken beautifully as it bakes.
08 -
For the best Easy Dump and Bake Chicken Tzatziki Casserole results, let it rest for 5 minutes before serving. This allows the sauce to settle and the flavors to meld. Serve directly from the dish alongside warm pita bread, rice, or a simple green salad.
# Notes:
01 -
💡 Squeeze your grated cucumber as dry as possible using a clean kitchen towel or paper towels before mixing it into the tzatziki sauce. Excess moisture can make the sauce watery during baking and prevent it from thickening properly.
02 -
🔄 Substitution tip: Boneless, skinless chicken breasts can be used in place of thighs, but reduce the bake time to 35–38 minutes and check for doneness early, as breasts cook faster and can dry out more quickly.
03 -
🧊 Storage tip: Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat individual portions in the microwave at 70% power or in a 350°F oven covered with foil for 10–12 minutes to keep the chicken moist.
04 -
🍽️ Serving tip: This casserole pairs beautifully with warm pita bread, fluffy couscous, or lemon herb rice. For a low-carb option, serve it over a bed of baby spinach or cauliflower rice to soak up all that delicious tzatziki sauce.
