How to Make Teriyaki Chicken Casserole Recipe
Step 1: Prepare the Teriyaki Sauce
Start by gently heating the soy sauce, water, honey, rice vinegar, sesame oil, garlic, and ginger in a small saucepan over medium heat. This step allows all the flavors to meld together nicely. Then, mix your cornstarch with a bit of water to make a slurry and stir it into the simmering sauce. Within a few minutes, you’ll see it thicken into that perfect, glossy teriyaki glaze that will coat every bite of the casserole.
Step 2: Combine the Ingredients
In a large bowl, toss together the cooked brown rice, shredded chicken, broccoli, carrots, red bell pepper, peas, and green onions. Pour the thickened teriyaki sauce over everything and stir gently to ensure every component is thoroughly coated, distributing that incredible flavor evenly throughout the casserole mix.
Step 3: Bake Your Casserole
Transfer the mixture to your prepared 9×13-inch baking dish, spreading it out so it bakes evenly. Cover it with foil to retain moisture, and bake in a 350°F oven for 20 minutes. Then, remove the foil to let the top develop a lovely slight crisp and bake for an additional 10 minutes. This finishing step creates a beautiful interplay of textures that will make you want to dive right in.
How to Serve Teriyaki Chicken Casserole Recipe

Garnishes
To elevate the presentation and introduce a bit of texture contrast, sprinkle toasted sesame seeds on top just before serving. These tiny seeds not only add a nutty crunch but also evoke the authentic Asian flavor palette that perfectly complements the dish.
Side Dishes
This casserole shines on its own but pairs wonderfully with a crisp green salad to cut through the richness or some steamed edamame for an extra protein boost. If you prefer something lighter, a side of pickled vegetables adds acidity to balance the sweet and savory notes of the casserole.
Creative Ways to Present
Serve this Teriyaki Chicken Casserole Recipe in individual ramekins for a cute, personalized touch at dinner parties. Alternatively, garnish with freshly chopped cilantro or sliced green onions to add bursts of freshness and vibrant color that make every serving feel special and inviting.
Make Ahead and Storage
Storing Leftovers
Place any leftover casserole in an airtight container and store it in the refrigerator for up to 3 days. This makes it a fantastic option for quick lunches or dinner the next day when you’re short on time but crave those mouthwatering teriyaki flavors again.
Freezing
You can freeze portions of this Teriyaki Chicken Casserole Recipe for up to 2 months. Make sure it cools completely before transferring into freezer-safe containers or bags. Thaw overnight in the fridge before reheating for a convenient, ready-made meal whenever you want.
Reheating
Reheat leftovers in the oven at 350°F for about 15-20 minutes or until warmed through, which helps maintain the casserole’s texture. Alternatively, microwave single servings on medium power to avoid drying out the rice and chicken while enjoying a hot, satisfying meal.
FAQs
Can I use white rice instead of brown rice?
Absolutely! White rice works perfectly in this recipe, offering a softer texture and quicker cooking time. The flavors of the casserole remain rich and delicious regardless of the rice you choose.
Is it possible to make this casserole vegetarian?
Yes! Substitute the shredded chicken with tofu cubes, tempeh, or a hearty mix of mushrooms and consider using vegetable broth to adjust the sauce for a satisfying vegetarian version.
How spicy is this Teriyaki Chicken Casserole Recipe?
The traditional recipe is mildly sweet and savory without heat, but if you like a bit of spice, adding a pinch of red pepper flakes to the sauce will provide a gentle kick that complements the other flavors beautifully.
Can I prepare the casserole in advance?
Yes, you can assemble the casserole up to a day in advance and store it covered in the fridge. When ready, bake it as directed. This makes the recipe a convenient option for meal prepping or entertaining with minimal day-of effort.
What can I substitute for honey in the sauce?
If you prefer a vegan or alternative sweetener, maple syrup or agave nectar work well in place of honey, maintaining the balance of sweetness that enhances the teriyaki glaze.
