Ingredients You'll Need

This recipe makes approximately 6 servings and uses familiar ingredients to create a flavorful, satisfying casserole.

Main Ingredients

• 1 ½ pounds boneless, skinless chicken breasts, cut into bite-sized pieces

• 1 ½ cups uncooked long-grain white rice

• 2 cups broccoli florets

• 1 red bell pepper, diced

• 1 cup sliced carrots

• 3 cloves garlic, minced

• 2 tablespoons olive oil

• 2 ½ cups low-sodium chicken broth

• 1 cup teriyaki sauce, divided

• 1 tablespoon sesame oil

• 1 teaspoon freshly grated ginger

• ½ teaspoon black pepper

• 1 tablespoon sesame seeds, for garnish

• 2 green onions, thinly sliced, for garnish

Optional Homemade Teriyaki Sauce

If you prefer to make your own sauce, combine the following ingredients in a small bowl:

• ½ cup soy sauce

• ¼ cup water

• 3 tablespoons honey or brown sugar

• 1 tablespoon rice vinegar

• 2 cloves garlic, finely minced

• 1 teaspoon freshly grated ginger

• 1 teaspoon cornstarch mixed with 1 tablespoon cold water

Whisk the ingredients together, then heat them in a small saucepan over medium heat until the mixture begins to thicken. Stir frequently, then remove from the heat. Allow the sauce to cool slightly before using it in the recipe.

Homemade sauce gives you more control over the sweetness and saltiness. If you use store-bought teriyaki sauce instead, choose a low-sodium variety if you want to keep the overall salt level moderate.

How to Make Teriyaki Chicken Casserole Step by Step

Step 1: Preheat the Oven and Prepare the Baking Dish

Preheat your oven to 375°F (190°C).

Lightly grease a 9-by-13-inch baking dish with cooking spray or a small amount of olive oil. This helps prevent the rice and chicken from sticking to the bottom during baking.

Prepare all your ingredients before starting. Cut the chicken into evenly sized pieces, dice the bell pepper, slice the carrots, chop the broccoli into small florets, and mince the garlic.

Having everything ready makes assembling the casserole much easier.

Step 2: Season and Brown the Chicken

Place the chicken pieces in a large bowl. Add the olive oil, sesame oil, black pepper, minced garlic, grated ginger, and about ¼ cup of the teriyaki sauce.

Toss everything together until the chicken is evenly coated.

Heat a large skillet over medium-high heat. Add the seasoned chicken and cook for approximately 3–4 minutes, stirring occasionally, until the outside begins to turn golden.

The chicken does not need to cook completely at this stage because it will finish cooking in the oven. Browning it briefly helps develop a deeper flavor.

Transfer the chicken to a plate and set it aside.

Step 3: Prepare the Rice and Vegetables

Spread the uncooked rice evenly across the bottom of the prepared baking dish.

Arrange the diced red bell pepper and sliced carrots over the rice. Add the broccoli florets, distributing the vegetables as evenly as possible.

Pour the chicken broth into a bowl and whisk in the remaining teriyaki sauce, leaving approximately ¼ cup of sauce aside for later.

Mix well so the sauce is evenly distributed throughout the liquid.

Important: Use uncooked long-grain white rice for this version of the recipe. The rice needs the liquid and baking time to cook properly. If you use brown rice, instant rice, or already-cooked rice, the liquid amounts and cooking time will need to be adjusted.
