Ingredients & Substitutions

1 pound raw diced chicken: Diced chicken breasts cook quickly and are a lean source of protein. You can substitute with chicken thighs for a juicier, more flavorful option.
2 cups instant rice: Instant rice cooks quickly and works perfectly in this casserole. You can use regular rice, but it will need a longer cooking time, and you might need to adjust the liquid.
3 cups frozen mixed vegetables: Frozen mixed vegetables are convenient and add great flavor and texture. You can substitute with fresh vegetables or a different vegetable mix of your choice, like broccoli, carrots, and peas.
1 cup teriyaki sauce: Teriyaki sauce adds a sweet and savory flavor. You can use low-sodium teriyaki sauce or make your own if you prefer.
2 tablespoons vegetable oil: Vegetable oil is used for sautéing the chicken. You can substitute with olive oil or sesame oil for a different flavor.
1 teaspoon garlic powder: Garlic powder adds a savory note. You can use fresh minced garlic (about 2 cloves) if preferred.
Salt and pepper: For seasoning the chicken and rice. Adjust to taste.
Optional sesame seeds and sliced green onions for garnish: These add a crunchy texture and fresh flavor to the finished casserole. You can also use chopped cilantro for a different touch.

Step-by-Step Instructions

Preheat the oven: Set your oven to 375°F (190°C) and prepare a casserole dish by greasing it lightly with cooking spray or a bit of oil.
Prepare the chicken: In a large bowl, toss the diced chicken with 1/2 cup of teriyaki sauce, garlic powder, salt, and pepper. Let the chicken marinate for about 5 minutes to absorb the flavors.
Cook the chicken: Heat the vegetable oil in a large skillet over medium-high heat. Add the marinated chicken and cook for about 5-7 minutes, stirring occasionally, until the chicken is mostly cooked through.
Prepare the rice: While the chicken is cooking, prepare the instant rice according to the package instructions.
Combine the ingredients: In the prepared casserole dish, combine the cooked chicken, prepared rice, frozen mixed vegetables, and the remaining 1/2 cup of teriyaki sauce. Stir everything together until it’s well mixed.
Bake the casserole: Cover the casserole dish with foil and bake in the preheated oven for 20-25 minutes, or until the vegetables are heated through and the flavors have melded together.
Garnish and serve: Remove from the oven and sprinkle with sesame seeds and sliced green onions if desired. Serve hot and enjoy!

How to Serve Teriyaki Chicken & Stir Fry Casserole

This casserole is a complete meal on its own, but you can pair it with a side of sautéed greens or a simple salad for a refreshing contrast. It also goes well with steamed dumplings or crispy spring rolls for a more Asian-inspired meal.

How to Store Teriyaki Chicken & Stir Fry Casserole

Leftovers can be stored in an airtight container in the fridge for up to 3 days. To reheat, microwave individual portions or bake at 350°F for 10-15 minutes until warmed through. If the casserole dries out, add a splash of water or chicken broth when reheating.

Pro Tips from the Chef

Customize the vegetables: Feel free to use your favorite vegetables in place of the frozen mix. Bell peppers, snap peas, or baby corn are all great options.
Use cooked chicken: If you have leftover cooked chicken, you can use that to save time. Just add it to the casserole when you combine the rice and veggies.
Make it spicy: For a little heat, add a dash of sriracha or red pepper flakes to the teriyaki sauce.
For extra flavor: Try using a bit of sesame oil for sautéing the chicken instead of vegetable oil. It adds a great, nutty flavor.
Top with cheese: For a cheesy twist, sprinkle some shredded cheese (like Monterey Jack or Cheddar) over the top of the casserole in the last 5 minutes of baking and bake until melted.

Variations

Vegetarian Option: Replace the chicken with tofu or tempeh for a vegetarian or plant-based version.
Low-Carb Version: Use cauliflower rice instead of regular rice for a lower-carb option.
Sweet and Spicy: Add a bit of honey and a splash of soy sauce to the teriyaki sauce to make it sweet and spicy.

FAQs

Can I make this casserole ahead of time?
Yes, you can assemble the casserole ahead of time and store it in the fridge for up to 24 hours before baking. Just cover it with foil and bake when you’re ready.

Can I freeze this casserole?
Yes, this casserole freezes well. Let it cool completely, then transfer it to an airtight container or freezer bag. It can be frozen for up to 3 months. To reheat, thaw overnight in the fridge and bake at 350°F for 20-25 minutes.

Can I use regular rice instead of instant rice?
Yes, you can use regular long-grain rice, but you’ll need to adjust the cooking time and increase the amount of liquid. You may also need to bake it longer to ensure the rice is fully cooked.
