There are casseroles that are good, and then there is teriyaki chicken casserole—the kind of sweet, savory, sticky, satisfying dish that brings together the bold flavors of Japanese-inspired teriyaki with the comforting familiarity of a baked casserole. Tender chicken, crisp-tender vegetables, and a rich, homemade teriyaki sauce are baked together with rice or noodles, then topped with sesame seeds and green onions. It is a complete, crowd-pleasing meal in one dish.
The beauty of this teriyaki chicken casserole is its simplicity. No standing over a wok, no constant stirring. You simply toss the chicken and vegetables in a homemade teriyaki sauce, layer them with rice, and bake until bubbly and golden. The sauce caramelizes slightly in the oven, creating a sticky, glossy finish that is absolutely irresistible.
This teriyaki chicken casserole is perfect for busy weeknights, for meal prep, or for any time you crave takeout flavors without the takeout price tag. It is also endlessly customizable—add broccoli, snap peas, or bell peppers. Make it spicy or keep it mild.

Ingredients
Here is everything you need for teriyaki chicken casserole:
For the Teriyaki Sauce:
· ½ cup low-sodium soy sauce (or tamari for gluten-free)
· ¼ cup water
· ¼ cup brown sugar (packed)
· 2 tablespoons honey
· 3 cloves garlic, minced
· 1 tablespoon fresh ginger, grated
· 2 tablespoons rice vinegar
· 1 tablespoon cornstarch mixed with 2 tablespoons cold water (slurry)
For the Casserole:
· 2 pounds boneless, skinless chicken breasts or thighs, cut into bite-sized pieces
· 2 cups cooked white or brown rice
· 2 cups broccoli florets
· 1 red bell pepper, diced
· 1 cup snap peas or snow peas (optional)
· 2 green onions, sliced (for garnish)
· 1 tablespoon sesame seeds (for garnish)
Step-by-Step Instructions
Step 1: Preheat and Prepare
Preheat your oven to 375 degrees Fahrenheit (190 degrees Celsius). Grease a 9×13-inch baking dish or a 3-quart casserole dish with non-stick spray.
Step 2: Make the Teriyaki Sauce
In a small saucepan, combine the soy sauce, water, brown sugar, honey, garlic, ginger, and rice vinegar. Bring to a simmer over medium heat. Whisk in the cornstarch slurry and cook for 1 to 2 minutes until the sauce thickens. Remove from heat.
Step 3: Combine the Casserole Ingredients
In a large bowl, combine the bite-sized chicken pieces, broccoli florets, bell pepper, and snap peas (if using). Pour the teriyaki sauce over the mixture and toss to coat evenly.
Step 4: Assemble the Casserole
Spread the cooked rice evenly in the bottom of the prepared baking dish. Top with the teriyaki chicken and vegetable mixture, spreading it into an even layer. Pour any remaining sauce from the bowl over the top.
Step 5: Bake
Cover the baking dish with aluminum foil. Bake for 25 minutes. Remove the foil and bake for another 10 to 15 minutes, until the chicken is cooked through (165 degrees Fahrenheit) and the sauce is bubbly and slightly caramelized.
Step 6: Garnish and Serve
Remove from the oven. Garnish with sliced green onions and sesame seeds. Serve hot.
Cooking Tips and Pro Tips for Best Results
· Use fresh ginger and garlic: Freshly grated ginger and minced garlic provide the best flavor.
· Do not overcook the chicken: Check for doneness at 25 minutes. Overcooked chicken becomes dry.
· Use low-sodium soy sauce: This allows you to control the salt level.
· Add vegetables at the end: If you prefer crunchier vegetables, add them during the last 10 minutes of baking.
· Make it spicy: Add ½ teaspoon of red pepper flakes or 1 teaspoon of sriracha to the sauce.
· Use chicken thighs for extra juiciness: Boneless, skinless chicken thighs are more forgiving than breasts.
Variations and Substitutions
· Teriyaki chicken with noodles: Substitute cooked lo mein or rice noodles for the rice.
· Teriyaki chicken with pineapple: Add 1 cup of pineapple chunks.
· Teriyaki chicken with mushrooms: Add 8 ounces of sliced cremini mushrooms.
· Spicy teriyaki chicken: Add 1 teaspoon of sriracha or red pepper flakes.
· Gluten-free: Use tamari instead of soy sauce.
· Low-carb or keto: Serve over cauliflower rice.
