The ingredients for this Teriyaki Chicken Casserole Recipe are simple but carefully chosen—fresh aromatics and staples like soy sauce and brown sugar come together with frozen stir-fry veggies and jasmine rice to create a balanced flavor and texture. Keeping some basics on hand makes this a go-to for weeknights.

• Boneless skinless chicken breasts: Use fresh or thawed for tenderness and easy shredding.

• Heat it up: Add a splash of sriracha or some red pepper flakes for a little kick.

How to Make Teriyaki Chicken Casserole Recipe

Step 1: Prep the Chicken and Baking Dish

Start by preheating your oven to 350°F and giving a 9×13-inch baking dish a good spray with non-stick cooking spray. Lay your boneless skinless chicken breasts flat in the dish, making sure they aren’t overlapping—this helps them cook evenly and makes shredding a breeze later.

Step 2: Make the Teriyaki Sauce on the Stove

In a medium saucepan, combine the soy sauce, ⅔ cup water, brown sugar, rice wine vinegar, fresh grated garlic and ginger, plus sesame oil. Bring this mixture to a boil over medium-high heat, stirring occasionally so nothing sticks or burns. While you wait, whisk together cornstarch and the remaining 2 tablespoons of water in a small bowl for your slurry—this will thicken the sauce perfectly.

Step 3: Thicken the Sauce and Pour Over Chicken

Once the sauce boils, slowly whisk in your cornstarch slurry and keep whisking constantly for about 30 to 45 seconds until the sauce thickens to a shiny, glossy coat. It should be thick enough to coat the back of a spoon. Pour 1 cup of this luscious teriyaki sauce evenly over the chicken breasts, then cover the dish tightly with aluminum foil.

Step 4: Bake and Shred the Chicken

Bake your chicken for 30-35 minutes until it reaches an internal temperature of 165°F. When it’s done, remove the foil carefully (watch out for steam), then shred the chicken right in the baking dish using two forks. I learned this trick from a friend—it saves so much cleanup!

Step 5: Mix in Veggies, Rice, and Sauce

Next, add your steamed frozen stir-fry vegetables, cooked jasmine rice, and the rest of the teriyaki sauce to the shredded chicken. Give everything a gentle but thorough stir to combine, ensuring each bite is saucy and full of flavor. Spread it evenly in the dish, and if you like, reserve a few tablespoons of sauce to drizzle over the top after baking.

Step 6: Final Bake and Serve

Return your casserole to the oven and bake for another 10-15 minutes until warmed through. Just before serving, drizzle the reserved teriyaki sauce on top for a glossy finish that makes this dish look restaurant-quality but is all home-cooked love.

How to Serve Teriyaki Chicken Casserole Recipe

Garnishes

I always sprinkle toasted sesame seeds and thinly sliced green onions on top of my Teriyaki Chicken Casserole Recipe. Not only do they add a pop of color, but the sesame seeds add a subtle crunch and nuttiness, while the green onions bring a fresh bite that cuts through the richness nicely.

Side Dishes

This casserole is quite filling on its own, but if you’re looking to round out your meal, I like to serve it alongside a simple cucumber salad or steamed edamame. These lighter sides complement the bold teriyaki flavors without overwhelming the meal.

Creative Ways to Present

For a special occasion, I’ve served this casserole in individual ramekins, topped with a little extra sauce and fresh cilantro leaves for a fancy flair. It’s a fun way to elevate the presentation but still keeps the casual, homey vibe I love about this dish.

Make Ahead and Storage

Storing Leftovers

I store leftover Teriyaki Chicken Casserole in airtight containers in the fridge, and it usually lasts for up to 3 days. The flavors actually deepen, so reheated portions taste just as good—if not better! Just be sure to cool it completely before sealing to avoid sogginess.

Freezing

Freezing works well with this casserole—I portion it into freezer-safe containers and it keeps great for up to 3 months. When freezing, try to reserve any fresh garnishes for after reheating so they stay vibrant and fresh.

Reheating

I reheat leftovers covered in the oven at 350°F for about 20 minutes, which keeps the casserole moist and evenly warm. If you’re in a hurry, microwave reheats fine too—just add a splash of water or extra teriyaki sauce to keep it from drying out.
