Preheat the oven to 375°F (190°C) and lightly grease a baking dish.
In a bowl, combine olive oil, minced garlic, paprika, oregano, thyme, salt, and pepper to make a seasoning mixture.
Coat the chicken pieces thoroughly with the seasoning mixture and set aside.
Spread the uncooked rice evenly in the prepared baking dish.
Add diced onion, cherry tomatoes, sun-dried tomatoes, sliced olives, lemon juice, and chicken broth over the rice, then stir gently to combine.
Place the seasoned chicken on top of the rice mixture.
Cover the baking dish tightly with foil and bake for 35 minutes.
Remove the foil, sprinkle crumbled feta cheese on top, and bake uncovered for an additional 10 to 15 minutes until the chicken is cooked through and the rice is tender.
Allow the dish to rest for 5 minutes after baking.
Garnish with fresh parsley before serving.
