How to Make Teriyaki Chicken Casserole
Step 1: Prep the Baking Dish and Preheat
Before anything else, preheat your oven to 350°F (175°C) and lightly grease a 9×13-inch baking dish. This tiny step keeps clean-up easy and ensures every serving of Teriyaki Chicken Casserole lifts out beautifully later on.
Step 2: Whisk Up the Homemade Teriyaki Sauce
In a small saucepan, combine soy sauce, water, honey, rice vinegar, sesame oil, garlic, and ginger. Place over medium heat and bring the mixture to a light simmer—you’ll smell that signature teriyaki aroma almost instantly. In a separate small bowl, blend the cornstarch with a tablespoon of water until smooth, then pour it into the saucepan. Stir constantly as the sauce gently thickens in about 2 to 3 minutes, becoming glossy and irresistibly fragrant.
Step 3: Mix the Chicken, Rice, and Veggies
Grab a large mixing bowl and toss in the cooked brown rice, shredded chicken, broccoli, carrots, red bell pepper, peas, and green onions. These colors and textures mixed together already look like a celebration, but soon they’ll be united by that rich teriyaki sauce.
Step 4: Combine with Sauce and Assemble
Pour the thickened teriyaki sauce right over the bowl of chicken, rice, and veggies. Stir everything together until each bit is evenly coated and the flavors begin to mingle. Spoon this vibrant mixture into your prepared baking dish, spreading it out into an even layer for consistent baking.
Step 5: Bake to Perfection
Cover the dish with foil and bake in your preheated oven for 20 minutes so everything melds together. Then, remove the foil and bake for an additional 10 minutes—this finishes it off with a slightly crispy, golden top that makes Teriyaki Chicken Casserole utterly irresistible. For the perfect finish, sprinkle with sesame seeds just before serving (if you’d like that tiny bit of crunch).
How to Serve Teriyaki Chicken Casserole

Garnishes
For a casserole that looks as good as it tastes, top each serving with a fresh scatter of sesame seeds or a sprinkle of sliced green onions. These last touches add texture and a pop of color, making the meal feel extra welcoming and festive.
Side Dishes
This dish is hearty enough to stand on its own, but if you want to round out your table, serve it with a crisp side salad, some roasted edamame, or a bowl of miso soup. Each of these makes for an easy pairing and helps soak up every last bit of that luscious teriyaki sauce.
Creative Ways to Present
If you’re in the mood for fun, serve Teriyaki Chicken Casserole in individual ramekins or mini cocottes—perfect for dinner parties or lunchbox-friendly leftovers. You could also spoon it into lettuce cups for a playful, fresh twist that’s great for lighter occasions.
Make Ahead and Storage
Storing Leftovers
Once cooled, transfer any leftover casserole to an airtight container and refrigerate for up to four days. The flavors actually deepen a bit overnight, so it’s a delicious next-day lunch or dinner you’ll look forward to eating again.
Freezing
Teriyaki Chicken Casserole freezes like a dream! Portion into individual containers or wrap the whole (cooled) casserole tightly in foil and plastic wrap. It will keep well in the freezer for up to three months. Just remember to label for easy meal planning!
Reheating
To reheat, simply pop a portion in the microwave until piping hot, or warm the casserole in a 350°F oven, covered, until heated through. If it’s looking a bit dry, add a splash of water or extra teriyaki sauce to bring back its signature sauciness.
FAQs
Can I use white rice instead of brown?
Absolutely! White rice works beautifully and will yield a slightly softer, creamier texture. You can also try quinoa or cauliflower rice if you’re looking to switch things up.
Is there a way to make Teriyaki Chicken Casserole vegetarian?
Yes—swap the shredded chicken for cubes of tofu or a medley of extra veggies. Use vegetable broth in the sauce if desired, and you’ll have a hearty, plant-based dinner ready in no time.
Can I add more veggies?
Of course! Feel free to toss in snap peas, baby corn, mushrooms, or even spinach. This casserole is super flexible and ideal for using up whatever you have on hand.
What’s the best way to shred cooked chicken?
Two forks work great to pull apart cooked chicken breast, or pulse it a few times in a stand mixer with a paddle attachment for super speedy shredding. Leftover rotisserie chicken is also a tasty shortcut.
How can I add some heat?
Add a pinch of red pepper flakes to the sauce, stir in a squeeze of Sriracha, or serve hot sauce on the side for anyone who likes a spicy kick with their Teriyaki Chicken Casserole.
