If you are looking for a dinner that checks every box — comforting, flavorful, colorful, and ridiculously easy to pull together — this Teriyaki Chicken and Rice Casserole is exactly what your weeknight routine has been missing. Everything comes together in a single baking dish, which means minimal cleanup and maximum satisfaction at the table.
The glossy, caramelized teriyaki sauce soaks right into the rice as it bakes, infusing every grain with a rich, savory-sweet flavor.

Once you try it, it will almost certainly become a regular in your dinner rotation.
Ingredients
- 1½ lb (680 g) boneless, skinless chicken breasts, diced
- 1½ cups uncooked long-grain white rice
- 2 cups chicken broth
- 1 cup teriyaki sauce
- 1½ cups broccoli florets
- 1 red bell pepper, diced
- 1 cup shredded carrots
- 3 garlic cloves, minced
- 1 tsp fresh grated ginger
- 1 tbsp sesame oil
- 1 tbsp sesame seeds
- 2 green onions, sliced
- Black pepper, to taste
Method
- Preheat the oven: Set your oven to 375°F (190°C). Lightly grease a 9 × 13-inch baking dish with cooking spray or a small amount of oil to prevent sticking.
- Prepare the sauce: In a medium bowl, whisk together the teriyaki sauce, chicken broth, sesame oil, minced garlic, and freshly grated ginger until everything is well combined. This sauce is the heart of the dish, so give it a good mix.
- Assemble the casserole: Spread the uncooked rice evenly across the bottom of the prepared baking dish. Layer the diced chicken, bell pepper, and shredded carrots on top. Season with black pepper to taste, then pour the teriyaki sauce mixture evenly over everything. Give it a gentle stir to distribute the ingredients without disturbing the layers too much.
- Bake covered: Cover the dish tightly with aluminum foil and bake for 40 to 45 minutes, until the rice is nearly tender and the chicken is cooked through. The foil traps steam and helps the rice cook evenly, so make sure the seal is snug.
- Add the broccoli: Remove the dish from the oven and carefully lift the foil. Stir in the broccoli florets, then replace the foil and return the dish to the oven. Bake for an additional 10 to 15 minutes, until the rice is fully tender and the chicken reaches an internal temperature of 165°F (74°C). If the rice looks a little dry at any point, stir in a splash of hot broth to loosen things up.
- Garnish and serve: Let the casserole rest for 5 minutes before serving — this helps everything settle and makes it easier to dish out. Scatter sesame seeds and sliced green onions generously over the top just before serving for a fresh, nutty finish.
Pro Tips for the Best Results
Use regular uncooked long-grain white rice for this recipe. Brown rice and instant rice behave very differently in the oven, and you would need to adjust both the liquid amounts and the baking time significantly if you choose to substitute them.
The teriyaki sauce you choose will have a big impact on the final flavor, so pick one you genuinely enjoy eating. Some brands lean sweeter while others are more savory and salty. Feel free to adjust the quantity slightly based on your personal preference. For an extra burst of flavor, drizzle a little additional teriyaki sauce over the casserole just before serving — it adds a beautiful glaze and deepens the overall taste.
Why This Recipe Works So Well
What makes this casserole so appealing beyond the flavor is its sheer practicality. You are essentially cooking protein, starch, and vegetables all at once in a single dish, with the oven doing the heavy lifting. The uncooked rice absorbs the savory teriyaki broth as it bakes, becoming deeply flavored rather than just a plain side. The broccoli is added toward the end so it stays bright green and tender rather than turning mushy. It is smart, efficient cooking that delivers results that taste like you spent far more effort than you actually did.
Whether you are feeding a hungry family on a Tuesday night or meal prepping for the week ahead, this Teriyaki Chicken and Rice Casserole delivers every single time. Save this one — you will come back to it again and again.
