Teriyaki Chicken Casserole

Warm from the oven and finished with an extra drizzle of homemade teriyaki sauce,
this Teriyaki Chicken Casserole is the kind of dinner that makes a busy evening feel a little easier.

Fried rice, tender shredded chicken, and colorful stir-fry vegetables all come together in one dish,
with plenty of sweet and savory teriyaki flavor in every bite.

I especially love how complete this casserole feels.
You have rice, chicken, and vegetables all tucked into the same baking dish,
so there’s no need to think about making several different things for dinner.

The chicken cooks right in the teriyaki sauce before it’s shredded,
and the remaining sauce gets stirred into the rice and vegetables before everything goes back into the oven.

It’s simple, satisfying, and a great recipe to keep around for those nights when a warm casserole sounds just right.

Why You’ll Love This Recipe

There’s a lot packed into this easy casserole. The fried rice makes it hearty, the chicken adds plenty of substance, and the stir-fry vegetables bring freshness and texture. But the homemade teriyaki sauce is what ties everything together.

Made with tamari soy sauce, brown sugar, honey, ginger, sesame oil, and garlic, the sauce has that familiar balance of savory and sweet. Part of it is used to bake the chicken, a little more gets mixed into the casserole, and another drizzle goes over the top just before serving.

And because the casserole includes the rice, vegetables, and chicken all in one, it can easily stand on its own as dinner. It’s especially handy when you want something comforting without putting together a long list of separate sides.

Ingredients for Teriyaki Chicken Casserole

Fried Rice – forms the hearty base of the casserole and soaks up the teriyaki sauce as everything bakes together.
Chicken Breast – baked in the teriyaki sauce until cooked through, then shredded before being mixed with the rice and vegetables.
Stir Fry Vegetables – a convenient mix of broccoli, sprouts, carrots, and snow peas that adds color, texture, and plenty of vegetables to the casserole.

For the Teriyaki Sauce

San-J Tamari Soy Sauce – gives the sauce its deep, savory flavor and provides the salty base for the teriyaki.
Water – balances the soy sauce and creates the right consistency for the sauce.
Brown Sugar – adds sweetness and helps create the classic sweet-and-savory teriyaki flavor.
Honey – adds another layer of sweetness while giving the finished sauce a rich, glossy quality.
Ground Ginger – brings a warm, slightly spicy note that pairs especially well with the soy sauce and garlic.
Sesame Oil – adds a rich, toasted sesame flavor, so a small amount goes a long way.
Garlic – adds savory depth and rounds out the flavors in the homemade teriyaki sauce.
Cornstarch – thickens the teriyaki sauce so it coats the chicken, rice, and vegetables instead of remaining thin.
Cold Water – combines with the cornstarch to make a smooth slurry before it is whisked into the hot sauce.

Step-by-Step Instructions

First, make the fried rice per the link above.

3 Cups Fried Rice

Heat the oven to 350 degrees F.

Make the Teriyaki Sauce

In a medium saucepan, stir together the soy sauce, water, brown sugar, honey, ground ginger, sesame oil, and garlic.

¾ Cup San-J Tamari Soy Sauce, ½ Cup Water, ⅓ Cup Brown Sugar, 1 Tablespoon Honey, ¾ teaspoon Ground Ginger, 1 teaspoon Sesame Oil, 1 Clove Garlic

Bring to a boil and cook for 1 minute.

In a small bowl, stir together the water and cornstarch.

2 Tablespoons Cornstarch, 2 Tablespoons Cold Water

Add 1 teaspoon of the hot soy mixture to the cornstarch mixture and then slowly pour everything into the boiling soy mixture, whisking until it begins to thicken. Set aside.

Place the chicken in a baking dish and pour 1 cup of the teriyaki sauce over the chicken.

1 Chicken Breast

Bake for 30 minutes, remove from the oven and shred.

Steam the veggies and then add the veggies, rice and chicken to an 8×8″ baking dish.

1 Package Stir Fry Vegetables

Add 3 tablespoons of the leftover teriyaki sauce and stir to combine.

Place the dish back in the oven for 15 minutes, remove from the oven and drizzle with a little more sauce.

Serve immediately.

Expert Tips

The teriyaki sauce is one of the most important parts of this casserole, so give the cornstarch step a little attention. Mix the cornstarch with the cold water first, then stir in the teaspoon of hot soy mixture before slowly whisking it back into the saucepan. Once the sauce begins to thicken, it’s ready.

Be sure to save the teriyaki sauce after measuring the cup that goes over the chicken. You’ll need 3 tablespoons of the leftover sauce for the rice, vegetables, and shredded chicken, along with a little more for that final drizzle.

Steam the stir-fry vegetables before they go into the baking dish. At that point, the rice is already prepared, the chicken has already been baked and shredded, and the vegetables have been steamed. The last 15 minutes in the oven simply brings all of those components together into one hot casserole.

And don’t skip that little bit of sauce at the end. Drizzling more teriyaki over the casserole just after it comes out of the oven gives the finished dish an extra layer of sauce right before serving.

Recipe Variations

This recipe is built around a straightforward combination of fried rice, chicken breast, and stir-fry vegetables, and you don’t need to add anything else to turn it into a complete dinner.

If you want to change things up without altering the casserole itself, the easiest place to do it is at serving time. Keep some of the teriyaki sauce nearby and let everyone add a little more to their own portion.

You can also make the same casserole ahead instead of baking it immediately. Assemble it, cover it, and refrigerate it for up to 24 hours before baking. That makes it especially useful when you know dinner the next day will be busy.

Storage & Reheating

If you have leftovers, let them cool and transfer them to an airtight container. They’ll keep in the refrigerator for up to 4 days, which makes this casserole useful for an easy lunch or another dinner later in the week.

To reheat it, warm individual servings in the microwave or cover the casserole and heat it in the oven until it’s warm and saucy again. A splash of extra teriyaki sauce after reheating can help bring back some of that saucy finish.

You can freeze the fully cooled casserole for up to 2 months as well. Thaw it overnight in the refrigerator, then bake it until heated through.

Serving Suggestions

This is one of those casseroles that really doesn’t need much alongside it. With fried rice, chicken, and stir-fry vegetables already in the dish, it makes a satisfying meal all by itself.

If you’d like something on the side, keep it fresh and simple. A crisp cucumber salad would be a nice contrast to the warm rice and chicken, while a light soup can turn the casserole into a larger meal without making dinner feel too heavy.

Whatever you serve with it, bring a little extra teriyaki sauce to the table. A spoonful over a warm serving of chicken, vegetables, and fried rice is a simple way to finish it.

Recipe FAQs

1. Can I make this casserole ahead of time?

Yes, you can definitely make it ahead. Assemble the casserole, cover it, and keep it in the refrigerator for up to 24 hours before baking. It’s a great option when you want to get dinner prepped and ready to go earlier in the day.

2. How do I keep the teriyaki sauce from getting lumpy?

Make sure to mix the cornstarch and cold water together until smooth first. Add 1 teaspoon of the hot soy mixture to the cornstarch mixture, then slowly whisk everything into the boiling sauce. Adding it gradually while whisking will help give you a smooth, thick teriyaki sauce.

3. Do I need to cook the vegetables before adding them?

Yes, you’ll want to steam the stir-fry vegetables first. The casserole only goes back into the oven for 15 minutes once everything is combined, so steaming the vegetables beforehand makes sure they’re cooked and ready to eat.

4. How do I know when the chicken is done?

Bake the chicken at 350°F for 30 minutes, as directed in the recipe. You can also check it with a meat thermometer to make sure it has reached 165°F in the thickest part before shredding.

5. What’s the easiest way to reheat leftovers without drying them out?

Reheat individual portions in the microwave or cover the casserole and warm it in the oven. If it seems a little dry, add a splash of extra teriyaki sauce after reheating. Leftovers can be stored in an airtight container in the refrigerator for up to 4 days.
