What you need to make teriyaki chicken casserole

Soy sauce: a little sweet and salty sauce that brings in an authentic flavoring.
Sugar: add a little more sweetness into your teriyaki sauce.
Apple cider vinegar: brings in a sour taste but tastes so good when cooked all together.
Garlic cloves: we love garlic in our home!
Ginger: a bit of a unique spice that brings out the asian flavors.
Pepper: just a pinch!
Cornstarch: helps to thicken the sauce.
Water: aids in the cornstarch by thickening and working together.
Chicken breasts: easy to cook and shred.
Rice: already cooked rice is best.
Vegetable stir fry mix: I like to buy the pre-packaged frozen blend at my local grocery store.

How to make Teriyaki Chicken Casserole

Make the teriyaki sauce: Preheat oven to 350 degrees. In a medium sized saucepan add the soy sauce, sugar, cider vinegar, garlic, ginger, and pepper. In a small bowl whisk together cornstarch and water. Slowly whisk into soy sauce mixture and bring to a boil over medium high heat. Reduce to a simmer and let thicken for about 3-5 minutes.
Baked then shred your chicken: In a 9×13 casserole dish add the chicken breasts. Pour half of the teriyaki sauce on top and bake for 25 minutes or until chicken is cooked throughout and no longer pink. Remove from oven and shred the chicken.
Combine rice, vegetables and chicken together: Stir in cooked rice and add vegetable mixture. Pour in remaining sauce. Mix together and baked until heated through for about 10-15 minutes.

Tips for making Teriyaki Chicken Casserole

If you prefer a brown rice over the white rice that will be great too for a healthier dish.
You can also use fried rice and have extra vegetables and chunks of egg mixture in the casserole.
Switch out any frozen stir fry that you prefer or make your own mix ins.
Use a chicken thigh instead of chicken breast. It is juicier and has more added chicken flavoring.

Storing Easy Teriyaki Chicken Casserole

This is a great meal to make for others.

It heats up nicely and freezes well for those unexpected, crazy-busy days at home.

Your family will still be able to enjoy the warmth of a family meal together.

Making ahead: This can be made up to 24 hours in advanced. Just cover and store in the refrigerator until ready to bake. You may need to add an additional few minutes or let rest for a few minutes outside of the refrigerator before baking it.
Freezer: It is best to freeze before baking. Cover the pan tightly with foil and write down the directions on top of the container. Remove the casserole from the freezer and let it thaw in the refrigerator during the day before baking. This will freeze for 1 month.
Warming up: Because of the homemade teriyaki sauce in this casserole, it reheats really well and won’t dry out. To reheat leftovers, heat your oven to 350 degrees Fahrenheit and bakes for 20-25 minutes or until it is warm through. You do not want to over bake.
