• 1/4 cup brown sugar
• 1/2 teaspoon ground ginger
• 1/2 teaspoon minced garlic
• 2 Tablespoons cornstarch + 2 Tablespoons water

For the casserole

How to Make Teriyaki Chicken Casserole

1. Prepare the baking pan

Preheat the oven to 350°F. Spray a 9×13-inch baking pan with non-stick spray.

2. Make the teriyaki sauce

Combine the soy sauce, ½ cup water, brown sugar, ginger, and garlic in a small saucepan and cover.

Bring the mixture to a boil over medium heat. Remove the lid and cook for one minute once boiling.

3. Thicken the sauce

Meanwhile, stir together the cornstarch and 2 tablespoons of water in a separate dish until smooth.

Once the sauce is boiling, add the cornstarch mixture to the saucepan and stir to combine. Cook until the sauce starts to thicken, then remove it from the heat.

4. Add the chicken and vegetables

Place the chicken breasts in the prepared baking pan.

Arrange the steamed vegetables around the chicken breasts. Pour one cup of the sauce over the chicken and vegetables.

Cover the pan with foil.

5. Bake the chicken

Bake for 30 minutes, or until the chicken reaches an internal temperature of 165°F.

Remove the casserole from the oven and carefully remove the foil.

Using two forks, shred the chicken while it is still in the dish.

6. Add the rice and remaining sauce

Add the cooked rice to the casserole dish.

Add most of the remaining sauce, reserving a little to drizzle over the top when serving.

Gently toss everything together until combined.

7. Finish baking

Return the casserole to the oven and cook for 10 minutes, or until everything is heated through.

Remove from the oven and let it stand for 5 minutes before serving.

Drizzle each serving with the remaining sauce.

Important Cooking Tips

• Use an instant-read thermometer: The chicken should reach 165°F before you shred it.
• Make the cornstarch slurry separately: Stir the cornstarch and water until smooth before adding it to the boiling sauce to help it incorporate evenly.
• Reserve some sauce: Keep a small amount aside for drizzling over the finished servings.
• Be careful with the foil: Remove it carefully after the initial 30-minute bake.
• Shred the chicken in the dish: The instructions call for shredding it with two forks while it remains in the casserole pan.
• Let it stand: Give the finished casserole 5 minutes before serving so it can settle after baking.
