In a 9×13 inch baking dish, combine the uncooked rice, chicken broth, condensed cream of chicken soup, salt, pepper, garlic powder, and onion powder. Stir well to combine.
Place the chicken breasts on top of the rice mixture.
Sprinkle the small pieces of butter over the chicken breasts.
Cover the baking dish tightly with aluminum foil. Make sure there are no gaps.
Bake for 1 hour, or until the chicken is cooked through and the rice is tender. Do not lift the foil during baking.
Remove the foil and bake for an additional 5-10 minutes, or until the chicken is lightly browned and the casserole is bubbly.
Let the casserole rest for 5-10 minutes before serving.
Notes
For a richer flavor, you can use chicken broth instead of water for cooking the rice.
If you don’t have condensed cream of chicken soup, you can make a simple homemade version by whisking together 1/4 cup butter, 1/4 cup flour, 1.5 cups milk, and 1/2 teaspoon salt, then cooking until thickened.
This recipe can be easily scaled up for larger families.
