Think of it as a chicken teriyaki casserole you can rely on for busy nights, meal prep, or even casual get-togethers. It’s the kind of dish that feeds everyone at the table without you feeling chained to the kitchen. And since it’s a healthy teriyaki chicken recipe loaded with vegetables and lean protein, it’s one you can feel good about serving again and again.

What You’ll Need

This recipe keeps the ingredient list straightforward.

For the sauce

  • ¾ cup low-sodium soy sauce
  • ½ cup water
  • ¼ cup brown sugar
  • ½ tsp ground ginger
  • ½ tsp minced garlic

To thicken

  • 2 Tbsp cornstarch + 2 Tbsp water

Main ingredients

  • 1 lb boneless, skinless chicken breasts
  • 12 oz stir-fry vegetable mix (fresh or frozen)
  • 3 cups cooked rice (white or brown)

Step-By-Step

1. Make the Teriyaki Sauce

In a small saucepan, combine soy sauce, water, brown sugar, ginger, and garlic. Bring to a gentle boil over medium heat. In a separate bowl, whisk cornstarch with water until smooth, then stir it into the sauce. Keep whisking until it thickens to a silky glaze. Remove from heat.

2. Bake the Chicken and Vegetables

Preheat your oven to 350°F. Lightly grease a 9×13-inch baking dish. Place the chicken breasts in the dish and scatter the vegetables around them. Pour about 1 cup of your teriyaki sauce over the top. Cover with foil and bake for 30 minutes, or until the chicken reaches 165°F internally.

3. Shred, Add Rice, and Mix

Remove the foil. Using two forks, shred the chicken right in the baking dish. Add the cooked rice, pour in most of the remaining sauce (save a little for drizzling later), and toss until everything is coated.

4. Final Bake

Pop the dish back in the oven, uncovered, for another 10 minutes so the flavors settle together.

5. Serve

Let it sit for a few minutes before serving. Drizzle with your reserved sauce and garnish with green onions or sesame seeds if you like. That’s your one pot teriyaki chicken — ready to eat.

Extra Cooking Tips for the Perfect Teriyaki Chicken Casserole

1. Use Fresh Vegetables if Possible

While frozen vegetables are convenient, fresh ones hold their texture better after baking. Lightly steam or blanch them before adding to the casserole so they stay vibrant and crisp-tender.

2. Don’t Overcook the Chicken

Dry chicken can ruin a good casserole. Bake just until it reaches 165°F — the final 10-minute bake with the rice will finish cooking it through without drying it out.

3. Let the Casserole Rest

Allowing it to sit for 5 minutes before serving helps the sauce settle and prevents it from being too runny.

4. Keep Extra Sauce on the Side

Some like a lightly coated casserole; others want extra sauce on every bite. Serve with a small dish of warmed teriyaki sauce so everyone can adjust to their taste.

Serving Ideas

Pair this teriyaki chicken with rice with a light Asian cucumber salad or miso soup for a complete meal. For gatherings, serve it alongside spring rolls or steamed dumplings.

If you’re a fan of texture, top each serving with toasted sesame seeds or crispy chow mein noodles before bringing it to the table.

Storage & Reheating

  • Fridge: Keep leftovers in an airtight container for up to 4 days.
  • Freezer: Store cooled portions for up to 2 months. Thaw in the fridge overnight.
  • Reheat: Warm in the oven at 350°F or in the microwave until hot. Add a splash of extra sauce if needed.

Nutrition & Health Notes

This easy chicken casserole isn’t just about flavor — it’s a balanced, nutrient-dense meal:

  • High protein from lean chicken breast.
  • Complex carbs from rice or whole grains.
  • Micronutrients & fiber from the vegetables.
  • Lower sodium if you use low-sodium soy sauce.

You can make it even lighter by using less sugar in the sauce or swapping half the rice for extra vegetables.
