Preheat your oven to 350°F (175°C) and grease a 9x13 inch baking dish with olive oil. Make sure it's well coated to avoid any sticky situations. Don't skimp on this step!
In a large bowl, combine the cubed chicken, rinsed rice, chicken broth, cream of chicken soup, sour cream, onion powder, garlic powder, thyme, parsley, salt, and pepper. Mix well until everything is evenly coated and happy together.
Pour the mixture into the prepared baking dish and spread it out evenly. This is all about an even bake, folks! No clumps allowed. Let's keep it classy!
Cover the dish tightly with aluminum foil and bake for 30 minutes. This helps steam the chicken and cook the rice. Trust me, the foil is your friend!
After 30 minutes, carefully remove the foil and bake for an additional 15 minutes, or until the chicken is cooked through and the edges are golden and bubbly. You'll know it's done when it smells like heaven!
Let the casserole sit for 5 minutes before serving. This helps everything come together nicely and saves you from burnt tongues. Plus, it makes for a prettier presentation!
