- 1 red bell pepper, diced
- 1 cup shredded carrots
- 3 green onions, sliced
For the Homemade Teriyaki Sauce
- ½ cup low-sodium soy sauce
- ¼ cup honey or brown sugar
- 2 tablespoons rice vinegar
- 1 tablespoon sesame oil
- 2 cloves garlic, minced
- 1 teaspoon freshly grated ginger
- 1 tablespoon cornstarch
- 2 tablespoons water

How to Make Teriyaki Chicken Casserole
1. Preheat the Oven
Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with cooking spray or a little oil and set it aside.
2. Make the Teriyaki Sauce
Add the soy sauce, honey or brown sugar, rice vinegar, sesame oil, garlic, and ginger to a small saucepan over medium heat. Stir well and bring the mixture to a gentle simmer.
In a small bowl, whisk together the cornstarch and water until completely smooth. Slowly pour the cornstarch mixture into the saucepan while stirring constantly.
Continue cooking for 2–3 minutes, or until the sauce thickens and becomes glossy. Remove from the heat and set aside.
3. Combine the Casserole Ingredients
In a large bowl, add the cooked chicken, cooked rice, broccoli, red bell pepper, shredded carrots, and green onions.
Gently toss everything together until the ingredients are evenly distributed.
4. Add the Teriyaki Sauce
Pour the homemade teriyaki sauce over the chicken and rice mixture. Stir gently until everything is evenly coated.
Make sure to mix thoroughly so the sauce reaches the rice, chicken, and vegetables throughout the casserole.
5. Transfer to the Baking Dish
Pour the mixture into the prepared baking dish and spread it into an even layer.
For extra flavor and a little texture, sprinkle sesame seeds and additional green onions over the top.
6. Bake
Cover the casserole loosely with aluminum foil and bake for 20–25 minutes, or until heated through and the vegetables are tender.
For slightly more roasted vegetables and a less covered finish, remove the foil during the final 5 minutes of baking.
7. Rest and Serve
Remove the casserole from the oven and let it rest for about 5 minutes before serving.
Garnish with toasted sesame seeds, sliced green onions, or an extra drizzle of teriyaki sauce. Serve warm and enjoy!
Tips for Making the Best Teriyaki Chicken Casserole
Use leftover chicken:
Rotisserie chicken or leftover grilled chicken is perfect for this recipe and makes preparation even faster.
Use jasmine rice:
Jasmine rice has a soft, slightly fragrant texture that pairs especially well with the sweet and savory teriyaki sauce.
Add extra vegetables:
Feel free to customize the casserole with your favorite vegetables. Snap peas, mushrooms, zucchini, and green beans are all delicious additions.
Add some heat:
For a spicy kick, mix ½ teaspoon of red pepper flakes or a little sriracha into the teriyaki sauce.
Make it crispy:
For a crunchy topping, sprinkle panko breadcrumbs mixed with a little melted butter over the casserole before baking.
How to Store and Reheat
Refrigerator:
Transfer leftovers to an airtight container and refrigerate for up to 4 days.
Freezer:
Place the cooled casserole in a freezer-safe container and freeze for up to 2 months.
Reheating:
Reheat individual portions in the microwave or warm the casserole in a 350°F (175°C) oven until heated through. If the rice seems dry, add a small splash of water or soy sauce before reheating.
