Preheat the oven to 375°F and lightly grease a baking dish.
In a mixing bowl, combine olive oil, minced garlic, paprika, oregano, thyme, salt, and pepper.
Coat the chicken thoroughly with the seasoning mixture and set aside.
Spread the uncooked rice evenly in the greased baking dish.
Add diced onion, cherry tomatoes, sun-dried tomatoes, sliced olives, lemon juice, and chicken broth to the rice.
Gently stir the rice mixture to combine all ingredients.
Place the seasoned chicken evenly on top of the rice mixture.
Cover the baking dish tightly with foil.
Bake covered for 35 minutes, then remove the foil.
Sprinkle crumbled feta cheese over the chicken and bake uncovered for an additional 10 to 15 minutes until the chicken is cooked through and rice is tender.
Remove from the oven and let rest for 5 minutes.
Garnish with fresh parsley and serve warm with your choice of side.
