  • Total Time: 45 minutes
  • Yield: 4

Ingredients

For the Casserole:

  • 1 pound raw diced chicken – Tender, juicy chicken as the base.
  • 2 cups instant rice – Convenient, quick-cooking rice.
  • 3 cups frozen mixed vegetables – A mix of carrots, peas, and broccoli works well, but customize with your favorites.
  • 1 cup teriyaki sauce – Adds savory-sweet flavor to the casserole.
  • 2 tablespoons vegetable oil – For cooking the chicken.
  • 1 teaspoon garlic powder – For added depth of flavor.
  • Salt and pepper – To taste, for seasoning.
  • Optional garnish: Sesame seeds and sliced green onions for a finishing touch.

Instructions

  1. Preheat the Oven:
    Preheat your oven to 375°F (190°C).

  2. Prepare the Chicken:
    In a large bowl, toss the diced chicken with ½ cup teriyaki sauce, garlic powder, salt, and pepper. Let it marinate for about 5 minutes.

  3. Cook the Chicken:
    Heat vegetable oil in a large skillet over medium-high heat.
    Add the marinated chicken and cook for about 5-7 minutes, or until mostly cooked through.

  4. Prepare the Rice:
    While the chicken is cooking, prepare the instant rice according to package instructions (typically involves boiling water, adding rice, and letting it sit covered for 5 minutes).

  5. Combine Ingredients:
    In a large casserole dish, combine the cooked chicken, prepared rice, frozen vegetables, and the remaining ½ cup teriyaki sauce. Stir everything together until well mixed.

  6. Bake:
    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.

  7. Garnish and Serve:
    Remove from the oven, and optionally sprinkle with sesame seeds and sliced green onions before serving.

Notes

  • Vegetarian Option – Swap the chicken for tofu or tempeh for a plant-based version.
  • Extra Veggies – Add extra bell peppers, snow peas, or mushrooms for more flavor and texture.
  • Spicy Option – Add a bit of sriracha or red pepper flakes for some heat.
  • Rice Alternative – Use brown rice or quinoa for a heartier, whole-grain option.
  • Extra Flavor – Drizzle with a little more teriyaki sauce or a dash of sesame oil before serving.
