Ingredients

1 lb (450g) boneless, skinless chicken breasts, diced
2 cups cooked white rice, completely cooled
1 cup broccoli florets, chopped small
1 red bell pepper, diced
1 tablespoon olive oil
1 cup teriyaki sauce
1 teaspoon grated fresh ginger (optional)
1 garlic clove, minced (optional)
¼ teaspoon black pepper
Pinch of red pepper flakes (optional)
1 tablespoon toasted sesame seeds
2 green onions, sliced
Extra teriyaki sauce for serving (optional)

Directions

Preheat the oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish. Heat the olive oil in a large skillet over medium-high heat and sear the diced chicken for 4–5 minutes until lightly browned but not fully cooked. If desired, simmer the teriyaki sauce with the ginger and garlic for 2–3 minutes before using. In a large bowl, combine the cooled rice, chicken, broccoli, bell pepper, black pepper, red pepper flakes, and teriyaki sauce. Gently mix until evenly coated, then spread the mixture into the prepared baking dish. Cover tightly with foil and bake for 20 minutes. Remove the foil, sprinkle with sesame seeds and half of the green onions, then bake uncovered for another 8–10 minutes until hot and lightly caramelized. Let the casserole rest for 5 minutes before garnishing with the remaining green onions and serving with extra teriyaki sauce if desired.

Helpful Tips

Day-old rice gives the best texture.
Don’t overmix the rice to keep it fluffy.
Pat the chicken dry before searing for better browning.
Add shredded carrots or snap peas for extra vegetables.
Finish with a squeeze of fresh lime for extra brightness.

Variations

Use brown rice instead of white rice.
Substitute rotisserie chicken for a quicker meal.
Replace chicken with tofu for a vegetarian version.
Add mushrooms, edamame, or zucchini.
Use gluten-free teriyaki sauce for a gluten-free meal.

Storage

Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat in the microwave or oven until warmed through.
