A no-fuss, flavor-packed Dump and Bake Chicken Tzatziki Casserole that combines creamy tzatziki, tender chicken, fresh veggies, and melty cheese — all in one comforting dish.
1. Preheat oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish.
2. In the prepared dish, combine uncooked rice, chicken broth, tzatziki sauce, oregano, garlic powder, salt, and pepper. Stir until well mixed.
3. Add the cooked chicken, cucumber, cherry tomatoes, and red onion. Mix gently and spread evenly in the dish.
4. Cover tightly with foil and bake for 35–40 minutes, or until rice is fully cooked and most of the liquid is absorbed.
5. Remove foil, sprinkle shredded mozzarella evenly on top, and bake uncovered for an additional 5–7 minutes until the cheese is melted and bubbly.
6. Allow the casserole to rest for 5 minutes before serving.
7. Garnish with fresh parsley before serving.
This dish pairs beautifully with a fresh green salad or warm pita bread for soaking up the creamy sauce.
