Preheat oven to 350℉.
Add all ingredients, except 'optional ingredients', in order into a 9x13 inch pan.
Stir gently to combine.
Cover pan tightly with foil.
Bake for 50 - 65 minutes. Stir every 15 - 20 minutes for a total of 3 big stirs while cooking. This helps the rice cook more evenly. Cover with foil again after each stir.
Bake time may vary by oven. You know it is done with liquid is absorbed, rice is cooked, and chicken is firm and cooked to 165℉ minimum. This recipe was tested only with jasmine rice - other rice options may need more liquid and longer bake times.
Top with optional toppings in a bowl or add to a burrito shell.
