This cheesy baked chicken casserole is a comforting and flavorful dish, perfect for a family dinner.
Preheat your oven to 350°F (175°C).
Always preheat your oven to ensure even cooking.
Lightly grease a 9x13-inch baking dish.
Use a non-stick spray or a small amount of butter to grease the dish.
Arrange the chicken breasts in the prepared baking dish.
Ensure the chicken pieces are evenly spaced for uniform cooking.
In a mixing bowl, combine the cream of chicken soup and diced onion.
Mix thoroughly to evenly distribute the onion.
Pour the soup mixture over the chicken breasts.
Spread the sauce evenly to cover all the chicken.
Sprinkle the shredded cheddar cheese over the soup mixture.
Distribute the cheese evenly for a consistent cheesy layer.
Top with the herbed stuffing mix, then drizzle the melted butter over the top.
Ensure the stuffing mix is evenly coated with butter for a crispy topping.
Bake in the preheated oven for about 1 hour, or until the chicken is fully cooked and the topping is golden brown.
Check the internal temperature of the chicken to ensure it reaches 165°F (74°C).
Let the casserole rest for 5 minutes before serving.
Allowing the dish to rest helps the flavors meld together.
