How to Make Teriyaki Chicken Casserole

Step 1: Prepare the Rice and Chicken

Cook the brown rice according to package instructions. While that’s cooking, dice the chicken into bite-sized pieces and lightly season with a little salt and pepper.

Step 2: Mix the Sauce

In a large bowl, combine teriyaki sauce, soy sauce, garlic, and ginger. Stir well to blend all those flavors together.

Step 3: Assemble the Casserole

In a lightly greased 9×13-inch baking dish, layer the cooked rice on the bottom. Top it with the raw chicken pieces and a generous layer of frozen stir-fry vegetables.

Step 4: Pour and Bake

Pour the sauce mixture evenly over the entire casserole. Cover tightly with foil and bake at 350°F for about 30-35 minutes, or until the chicken is fully cooked and the veggies are tender.

Step 5: Garnish and Serve

Once baked, sprinkle sesame seeds and chopped green onions over the top for that final fresh, crunchy touch.

Pro Tips for Making the Recipe

• Precook Your Rice: Don’t skip this step — using cooked rice ensures the casserole isn’t watery.
• Cut Chicken Evenly: Try to dice your chicken into uniform pieces so they cook at the same rate.
• Taste Your Sauce: If your teriyaki sauce is very sweet, balance it out with a splash of extra soy sauce or a squeeze of lime.
• Don’t Overbake: Keep an eye on the chicken; overbaking can make it dry. As soon as it’s cooked through, it’s done!

How to Serve

This Teriyaki Chicken Casserole is hearty enough to stand on its own, but if you want to round out the meal, here are some ideas:

Garnishes:

Top each serving with extra green onions, toasted sesame seeds, or a light drizzle of extra teriyaki sauce.

Side Dish:

Pair it with a crisp Asian-style slaw, steamed edamame, or a simple cucumber salad for a refreshing side.

For a Fun Twist:

Spoon it into lettuce cups for a playful, low-carb serving idea!

Make Ahead and Storage

Storing Leftovers

Place any leftovers in an airtight container and refrigerate for up to 4 days. The flavors actually deepen, making it even more delicious the next day.

Freezing

Yes, you can freeze it! Allow the casserole to cool completely, then transfer to a freezer-safe container. Freeze for up to 3 months.

Reheating

Reheat individual portions in the microwave, adding a splash of water or extra sauce to keep it moist. If reheating from frozen, thaw overnight in the fridge first.

FAQs

Can I use a homemade teriyaki sauce instead of store-bought?

Absolutely! Homemade teriyaki sauce can bring a fresher, less processed flavor. It’s typically made with soy sauce, brown sugar, garlic, ginger, and a little cornstarch to thicken.

Do I need to thaw the frozen vegetables first?

No need! Just toss them in frozen. They’ll cook perfectly while the casserole bakes, saving you time and keeping them nice and vibrant.

Can I make this casserole ahead of time?

Yes! You can assemble the casserole, cover it, and refrigerate it for up to 24 hours before baking. Just add an extra 5-10 minutes to the bake time if it’s going straight from fridge to oven.

What’s the best way to keep the chicken juicy?

The key is not to overcook it. Dicing the chicken into small, even pieces and covering the casserole while baking helps trap moisture and keep everything tender and juicy.
