Preheat your oven to 350°F (175°C).
In a skillet, heat olive oil over medium heat and season chicken with garlic powder, salt, and pepper.
Cook chicken for about 4-5 minutes per side, just until browned (it'll finish in the oven).
In a large bowl, mix cream of chicken soup, softened cream cheese, chicken broth, onion powder, and parsley.
Fold in the cooked rice until it’s all cozy and combined.
Spread the creamy rice mixture in a greased 9x13-inch baking dish.
Place the browned chicken breasts over the rice.
Sprinkle mozzarella cheese over everything like you mean it.
Bake uncovered for 40-45 minutes, or until the chicken is cooked through and the edges are bubbling.
Let it cool for a few minutes (torture, I know), then serve warm and creamy!
