How to Make Easy Teriyaki Chicken Casserole Recipe

Step 1: Whip Up the Teriyaki Sauce

Begin by combining your soy sauce, brown sugar, apple cider vinegar, minced garlic, ground ginger, and black pepper in a medium saucepan. This mix will soon transform into a luscious teriyaki glaze. To thicken it up, whisk cornstarch and water in a small bowl before slowly adding it to the sauce. Bring everything to a boil, then simmer for 3-5 minutes until it thickens to a shiny, syrupy consistency that’s ready to coat your chicken perfectly.

Step 2: Bake the Chicken with Flavor

Place the chicken breasts in a 9×13 casserole dish and generously pour half of the teriyaki sauce over them. Pop the dish into a 350°F oven for about 25 minutes, or until the chicken is cooked through and tender. Once out of the oven, shred the chicken right in the dish—this step ensures every bite is infused with that irresistible sauce.

Step 3: Bring It All Together

Next, fold in the cooked rice and steamed vegetable stir fry mix with the shredded chicken, then drizzle the remaining teriyaki sauce evenly across the top. Give everything a good mix so the flavors meld beautifully. Return the casserole to the oven for another 10-15 minutes until everything is warmed through and the flavors have mingled into pure comfort food bliss.
