Ingredients

  • Chicken & Base
  • 2 cups cooked chicken breast diced or shredded
  • 3 cups cooked white rice jasmine or long-grain works well
  • 1 ½ cups broccoli florets
  • 1 red bell pepper diced
  • 1 cup shredded carrots
  • 3 green onions sliced (divided)
  • Optional: Sesame seeds for garnish
  • Homemade Teriyaki Sauce
  • ½ cup low-sodium soy sauce
  • ¼ cup honey or brown sugar
  • 2 tbsp rice vinegar
  • 1 tbsp sesame oil
  • 2 cloves garlic minced
  • 1 tsp fresh grated ginger
  • 1 tbsp cornstarch
  • 2 tbsp water to mix with cornstarch

Instructions

  • Preheat & Prep: Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with non-stick spray or a little oil.
  • Make the Slurry: In a small bowl, mix the cornstarch with 2 tablespoons of water until completely smooth. Set aside.
  • Simmer the Teriyaki Sauce: In a small saucepan over medium heat, combine the soy sauce, honey, rice vinegar, sesame oil, minced garlic, and grated ginger. Bring the mixture to a gentle simmer.
  • Thicken the Sauce: Slowly whisk the cornstarch slurry into the simmering sauce. Continue to cook and stir until the sauce has thickened nicely (about 2–3 minutes). Remove from heat.
  • Assemble the Casserole: In a large mixing bowl, combine the cooked rice, cooked chicken, broccoli florets, diced bell pepper, shredded carrots, and half of the sliced green onions.
  • Mix it Up: Pour about ¾ of the thickened teriyaki sauce over the rice and chicken mixture. Gently stir until everything is evenly coated.
  • Transfer & Top: Pour the coated mixture into your prepared 9x13 baking dish, spreading it out into an even layer. Drizzle the remaining teriyaki sauce evenly over the top.
  • Bake: Cover the baking dish tightly with aluminum foil and bake for 20 minutes.
  • Finish & Brown: Remove the foil and bake for an additional 5–10 minutes, or until the casserole is heated completely through and slightly golden and bubbly on top.
  • Garnish & Serve: Remove from the oven. Sprinkle with sesame seeds and the remaining green onions before serving warm. Enjoy!
