How to Make Teriyaki Chicken & Stir Fry Casserole Recipe
Step 1: Preheat the Oven
Start by preheating your oven to 375°F (190°C). Getting the oven ready early ensures your casserole will bake evenly and your timing will be spot on.
Step 2: Prepare the Chicken
In a large bowl, toss the diced chicken with half a cup of teriyaki sauce, garlic powder, and a sprinkle of salt and pepper. Letting it marinate—even for just about 5 minutes—allows the flavors to penetrate the meat, making every bite so flavorful.
Step 3: Cook the Chicken
Heat the vegetable oil in a large skillet over medium-high heat, then add the marinated chicken. Cook it for about 5 to 7 minutes until it’s mostly cooked through and beautifully coated in that rich teriyaki glaze. This step seals in the juices, keeping the chicken tender inside.
Step 4: Prepare the Rice
While your chicken is sizzling, prepare the instant rice according to the package directions. Usually, this means boiling the water, adding the rice, and letting it stand covered for 5 minutes. This approach keeps the rice fluffy and ready to absorb all the combined flavors later.
Step 5: Combine Ingredients
Grab your favorite large casserole dish and combine the cooked chicken, prepared rice, frozen mixed vegetables, and the remaining half cup of teriyaki sauce. Stir everything gently but thoroughly, so the sauce coats each ingredient evenly and the vegetables are well distributed.
Step 6: Bake the Casserole
Cover your casserole dish tightly with foil, then bake it for 20 to 25 minutes. This baking step warms the vegetables and lets all those delicious flavors mingle and meld into one irresistible dish. The result is a comforting casserole with layers of tender chicken, perfectly cooked rice, and crisp-tender veggies.
Step 7: Garnish and Serve
Once out of the oven, you can sprinkle sesame seeds and sliced green onions over the top, if you like, to add a burst of texture and a pop of color. Then serve it while it’s warm and enjoy every mouthwatering bite of this Teriyaki Chicken & Stir Fry Casserole Recipe.
How to Serve Teriyaki Chicken & Stir Fry Casserole Recipe

Garnishes
Fresh garnishes like toasted sesame seeds and thinly sliced green onions elevate this casserole visually and taste-wise. The sesame seeds give a subtle nutty crunch, and the green onions bring a fresh, vibrant snap that contrasts wonderfully with the savory sweetness of the teriyaki sauce.
Side Dishes
This casserole is quite the complete meal, but if you want to go all out, pair it with a light cucumber salad or steamed edamame for extra veggies and texture variety. A side of pickled ginger can also add a fun zing to complement the flavors beautifully.
Creative Ways to Present
For a fun twist, serve the casserole in individual ramekins topped with garnishes. You could also spoon it over a bed of fresh greens for a warm salad, or simply keep it classic straight from the casserole dish for a cozy family-style meal. Either way, it’s a guaranteed crowd-pleaser!
Make Ahead and Storage
Storing Leftovers
Place any leftover Teriyaki Chicken & Stir Fry Casserole Recipe in an airtight container and refrigerate. It will stay fresh for up to 3 days, making it a perfect meal to enjoy the next day or pack for lunch.
Freezing
If you want to save it for later, this casserole freezes well! Just make sure to cool it completely, then transfer it to a freezer-safe container. It can be frozen for up to 2 months without losing much flavor or texture.
Reheating
To reheat, thaw overnight in the fridge if frozen, then warm in the oven at 350°F (175°C) for 15–20 minutes or until heated through. You can also microwave portions for a quick lunch, stirring halfway through to heat evenly.
FAQs
Can I use fresh vegetables instead of frozen?
Absolutely! Fresh vegetables like broccoli florets, sliced carrots, and peas can be used instead of frozen. Just be sure to sauté them briefly or blanch so they cook fully during the baking process.
Is it possible to make this recipe gluten-free?
Yes! Just use a gluten-free teriyaki sauce and confirm your instant rice and any sauces are free of gluten. This way, you keep all the delicious flavors safe for those with gluten sensitivities.
Can I substitute brown rice for instant rice?
You can, but brown rice requires longer cooking time. To use brown rice, cook it fully before mixing it into the casserole or adjust cooking times accordingly so the dish doesn’t dry out.
What other proteins can I use?
This recipe is very versatile! You can swap chicken with diced turkey, shrimp, or even firm tofu for a vegetarian twist. Just adjust the cooking time based on the protein you choose.
How spicy is this casserole?
This Teriyaki Chicken & Stir Fry Casserole Recipe is on the mild side, making it perfect for all ages. If you like a bit of heat, feel free to add crushed red pepper flakes or a dash of hot sauce during cooking or at the table.
