Ingredients You’ll Need

Here is everything you need to make this delicious casserole.

For the Casserole

2 pounds boneless, skinless chicken breasts, cut into bite-sized pieces
2 cups uncooked long-grain white rice
3 cups low-sodium chicken broth
1 cup broccoli florets
1 red bell pepper, diced
1 cup shredded carrots
2 tablespoons olive oil
2 green onions, sliced
1 tablespoon sesame seeds (optional)
Salt and black pepper, to taste

For the Homemade Teriyaki Sauce

½ cup low-sodium soy sauce
¼ cup honey
2 tablespoons brown sugar
2 tablespoons rice vinegar
2 cloves garlic, minced
1 teaspoon freshly grated ginger
1 tablespoon cornstarch
2 tablespoons water

Step-by-Step Instructions

Step 1: Prepare Your Oven and Baking Dish

Begin by preheating your oven to 375°F (190°C).

Lightly grease a 9-by-13-inch baking dish with cooking spray or a little olive oil. This will help prevent the rice and chicken from sticking during baking.

Rinse the rice under cold water until the water runs mostly clear. This helps remove excess starch and keeps the rice from becoming overly sticky.

Set the prepared rice aside while you work on the sauce and chicken.

Step 2: Make the Homemade Teriyaki Sauce

In a medium saucepan, combine the soy sauce, honey, brown sugar, rice vinegar, minced garlic, and grated ginger.

Place the saucepan over medium heat and stir until the honey and brown sugar dissolve completely.

In a small bowl, whisk together the cornstarch and water until smooth. Slowly pour this mixture into the saucepan while stirring continuously.

Allow the sauce to simmer for approximately 2–3 minutes, or until it becomes slightly thickened and glossy.

Remove the saucepan from the heat and set the teriyaki sauce aside. Its sweet, savory, and slightly tangy flavor will bring the entire casserole together.

Step 3: Season and Brown the Chicken

Cut the chicken breasts into evenly sized, bite-sized pieces.

Season them lightly with salt and black pepper.

Heat the olive oil in a large skillet over medium-high heat. Add the chicken pieces in a single layer, working in batches if necessary.

Cook for approximately 3–4 minutes, stirring occasionally, until the chicken is lightly golden on the outside. It does not need to be completely cooked at this stage because it will finish cooking in the oven.

Remove the chicken from the heat and set aside.
