Ingredients

• 3 cups cooked chicken, diced or shredded
• 3 cups cooked white or brown rice
• 3 cups frozen broccoli, carrot, and bell pepper blend, thawed
• 1 cup teriyaki sauce
• ½ cup pineapple chunks, drained
• 2 green onions, sliced, optional
• Sesame seeds for serving, optional

How to Make Chicken Teriyaki Casserole

1. Preheat the Oven

Preheat your oven to 375°F (190°C).

Lightly grease a 9×13-inch casserole dish.

This recipe works especially well with leftover cooked chicken and rice, making it an excellent way to turn leftovers into a completely different dinner.

2. Prepare the Chicken

Place the cooked chicken in a large mixing bowl.

You can use baked, poached, grilled, or rotisserie chicken. Cut or shred it into bite-size pieces so it distributes evenly throughout the casserole.

3. Add the Rice and Vegetables

Add the cooked rice and thawed vegetables to the chicken.

Gently toss everything together.

If the vegetables contain excess water after thawing, drain them first. Too much moisture can make the casserole watery.

4. Add the Teriyaki Sauce

Pour about ¾ cup teriyaki sauce over the chicken, rice, and vegetables.

Add the drained pineapple chunks.

Stir until everything is evenly coated in the glossy sauce.

Reserve the remaining teriyaki sauce for finishing.

5. Assemble the Casserole

Transfer the chicken and rice mixture to your prepared baking dish.

Spread everything into an even layer.

Drizzle a little of the reserved teriyaki sauce across the top.

6. Bake

Cover the casserole loosely with aluminum foil and bake for 20 minutes.

Remove the foil and continue baking for another 10–15 minutes, or until the casserole is thoroughly hot and the sauce is bubbling around the edges.

Because the chicken and rice are already cooked, the goal is to heat everything thoroughly without drying out the chicken.

7. Finish and Serve

Remove the casserole from the oven and let it rest for about 5 minutes.

Drizzle with the remaining teriyaki sauce.

If desired, sprinkle sliced green onions and sesame seeds over the top just before serving.

Homemade Teriyaki Sauce Option

If you prefer homemade sauce, combine soy sauce, brown sugar or honey, garlic, ginger, and a little water in a saucepan.

Simmer until the sugar dissolves, then thicken with a small amount of cornstarch mixed with cold water.

For the easiest version, bottled teriyaki sauce works perfectly.

Tips for the Best Chicken Teriyaki Casserole

Use cooked rice rather than uncooked rice for predictable results. Raw rice requires a different amount of liquid and a substantially different baking time.

Drain the vegetables well before assembling the casserole.

Don’t add all the teriyaki sauce immediately if your brand is especially salty or strongly flavored. You can always add more after baking.

For a sweeter teriyaki casserole, pineapple is an excellent addition. For a more savory version, simply leave it out.

Easy Variations

Chicken thighs can replace chicken breast for a juicier casserole.

You can also use broccoli, carrots, snap peas, bell peppers, edamame, or water chestnuts.

For extra sweetness, add additional pineapple chunks.

For a little heat, add crushed red pepper flakes or a drizzle of sriracha.

Brown rice can replace white rice for a slightly nuttier flavor and firmer texture.

What to Serve With Chicken Teriyaki Casserole

Because this casserole already includes chicken, rice, and vegetables, it can easily be served as a complete dinner.

For a larger meal, pair it with steamed broccoli, Asian-style cucumber salad, roasted green beans, or a simple cabbage slaw.

You can also serve additional warm teriyaki sauce on the side.

How to Store Leftovers

Transfer leftovers to an airtight container and refrigerate promptly for up to 3–4 days.

Reheat individual portions in the microwave until thoroughly hot.

If the rice seems dry after refrigeration, add a small spoonful of teriyaki sauce or a splash of water before reheating.

Frequently Asked Questions

Can I use rotisserie chicken?

Yes. Rotisserie chicken makes this casserole particularly quick and convenient.

Can I use frozen vegetables?

Absolutely. Thaw them and drain away excess moisture before adding them to the casserole.

Can I make Chicken Teriyaki Casserole ahead?

Yes. Assemble the casserole, cover it, and refrigerate until you’re ready to bake. A refrigerated casserole may need a little additional oven time.

Can I use uncooked rice?

This particular recipe is designed for cooked rice. Using uncooked rice requires additional liquid and different cooking times.

Can I leave out the pineapple?

Yes. Pineapple is optional and can simply be omitted for a more savory teriyaki flavor.
