Preparation

  • Preheat oven to 350°F and spray a 9x13-inch baking pan with non-stick spray.
  • Combine soy sauce, ½ cup water, brown sugar, ginger, and garlic in a small saucepan, bring to a boil over medium heat, then cook for one minute without the lid.
  • In a separate dish, stir cornstarch and 2 tablespoons of water until smooth, then add to the boiling sauce and cook until thickened before removing from heat.
  • Place chicken breasts and steamed vegetables in the prepared pan, pour one cup of sauce over them, cover with foil, and bake for 30 minutes or until chicken reaches 165°F.
  • Remove the pan from the oven, carefully take off the foil, and shred the chicken directly in the dish using two forks.
  • Add the cooked rice and most of the remaining sauce to the casserole dish, gently toss to combine, and reserve a small amount of sauce for serving.
  • Return the dish to the oven for 10 minutes until heated through, then remove and let stand for 5 minutes before serving, drizzling each portion with the reserved sauce.
