Ingredients

  • For the Casserole:
  • 1.5 lbs boneless skinless chicken breasts cut into bite-sized pieces
  • 1 tsp olive oil garlic-infused if desired
  • Salt and black pepper to taste
  • 32 oz frozen mixed vegetables Asian-style, unsauced
  • 3 cups cooked brown rice
  • For the Teriyaki Sauce:
  • ¾ cup low sodium soy sauce
  • ½ cup water
  • cup packed brown sugar
  • 1 tbsp honey
  • ¾ tsp ground ginger
  • ½ tsp minced garlic
  • For the Slurry:
  • 2 tbsp cornstarch
  • 2 tbsp cold water
  • Optional: splash of apple cider vinegar to adjust thickness

Instructions

  • Preheat oven to 350°F.
  • Cook the Chicken: Heat olive oil in a large skillet over medium-high heat. Sear chicken in batches until browned. Season lightly with salt and pepper. Set aside.
  • Sauté the Veggies: In the same skillet, add a bit more oil and sauté the frozen vegetables until just tender. Combine with the chicken in a large casserole dish.
  • Add Rice: Stir in the cooked brown rice with the chicken and vegetable mixture.
  • Make the Sauce: In a saucepan, combine soy sauce, water, brown sugar, honey, ginger, and garlic. Bring to a boil. Mix cornstarch and cold water in a small bowl to make a slurry, then stir it into the sauce. Simmer until thickened. Add a splash of apple cider vinegar if too thick.
  • Assemble: Pour most of the sauce over the casserole mixture and stir to combine. Reserve a small amount for topping after baking.
  • Bake: Bake uncovered for 15 minutes at 350°F.
  • Finish & Serve: Drizzle remaining sauce over the top after baking. Serve hot.
