Ingredients
Chicken and Rice Base
- 2 cups cooked chicken breast, diced or shredded
- 3 cups cooked white rice (jasmine or long-grain rice works best)
- 1½ cups broccoli florets
- 1 red bell pepper, diced
- 1 cup shredded carrots
- 3 green onions, sliced
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 fresh grated ginger
- 1 tablespoon cornstarch
- 2 tablespoons water (for mixing with cornstarch)
How to Make Teriyaki Chicken Casserole
1. Preheat the Oven
Start by preheating your oven to 375°F (190°C). While the oven heats up, lightly grease a 9×13-inch baking dish with cooking spray or a small amount of oil. This prevents the casserole from sticking and makes cleanup easier later.
2. Prepare the Teriyaki Sauce
In a small saucepan over medium heat, combine the soy sauce, honey (or brown sugar), rice vinegar, sesame oil, minced garlic, and grated ginger. Stir the ingredients together and bring the mixture to a gentle simmer.
In a separate small bowl, whisk the cornstarch and water until smooth. Slowly pour this mixture into the saucepan while stirring continuously. Cook for about 2–3 minutes, until the sauce thickens and becomes glossy. Once thickened, remove it from the heat and set it aside.
The homemade sauce is what gives this dish its signature flavor. It adds sweetness from the honey, saltiness from the soy sauce, and a subtle nutty aroma from the sesame oil.
3. Prepare the Casserole Mixture
In a large mixing bowl, combine the following ingredients:
- Cooked rice
- Cooked chicken
- Broccoli florets
- Diced red bell pepper
- Shredded carrots
- Sliced green onions
Mix everything gently so the ingredients are evenly distributed throughout the bowl.
4. Add the Teriyaki Sauce
Pour the prepared teriyaki sauce over the chicken and rice mixture. Stir everything together until the sauce coats all the ingredients evenly. This step ensures that every bite of the casserole is full of flavor.
5. Assemble the Casserole
Transfer the mixture into the prepared baking dish. Spread it evenly with a spoon or spatula so the casserole cooks evenly.
If you like extra flavor, you can sprinkle sesame seeds or additional sliced green onions on top before baking.
6. Bake the Casserole
Cover the baking dish loosely with aluminum foil and place it in the oven. Bake for 20–25 minutes, or until the casserole is heated through and the vegetables become slightly tender.
If you prefer slightly roasted vegetables, you can remove the foil during the last 5 minutes of baking.
7. Serve and Enjoy
Once the casserole is done baking, remove it from the oven and let it rest for about 5 minutes before serving. This allows the sauce to settle and makes the casserole easier to scoop.
Serve it warm and garnish with:
- Toasted sesame seeds
- Extra green onions
- A drizzle of teriyaki sauce
Tips for the Best Teriyaki Chicken Casserole
Use leftover chicken:
Rotisserie chicken or leftover grilled chicken works perfectly in this recipe and saves time.
Choose the right rice:
Jasmine rice is ideal because it has a soft texture and slightly fragrant flavor that pairs well with teriyaki sauce.
Add more vegetables:
You can customize the casserole with vegetables such as:
- Snap peas
- Mushrooms
- Zucchini
- Green beans
Make it spicy:
If you like a little heat, add ½ teaspoon chili flakes or a small amount of sriracha to the sauce.
Make it crispy on top:
Sprinkle panko breadcrumbs mixed with a little melted butter over the casserole before baking for a crunchy topping.
How to Store and Reheat
Refrigerator:
Store leftovers in an airtight container in the refrigerator for up to 4 days.
Freezer:
This casserole also freezes well. Place it in a freezer-safe container and freeze for up to 2 months.
Reheating:
Reheat in the microwave or oven at 350°F (175°C) until warmed through. You may want to add a small splash of water or soy sauce to keep it moist.
