Step-by-Step Instructions
- Prepare the Oven and Dish:
- Preheat your oven to 350°F and lightly grease a 9×13 inch baking dish. The light coating of oil prevents sticking and makes cleanup easier. Take your time ensuring even coverage for best results.
- Create the Creamy Base:
- In a spacious mixing bowl combine the cream of chicken soup sour cream and chicken broth. Whisk until completely smooth with no lumps remaining. This mixture forms the velvety sauce that will surround the chicken and provide moisture during cooking.
- Prepare the Chicken Layer:
- Season your chicken breasts generously with salt and pepper on both sides then arrange them in a single layer in your prepared baking dish. Pour the creamy mixture evenly over the chicken ensuring each piece is well coated. The chicken will absorb these flavors as it cooks.
- Add Vegetables and Cheese:
- If using vegetables distribute them evenly around the chicken pieces. Sprinkle the shredded Swiss cheese over everything creating a layer that will melt into a gooey blanket during baking. The vegetables add pops of color and nutrition while the cheese creates a savory layer.
- Create the Stuffing Topping:
- In a separate bowl combine the stuffing mix with melted butter tossing thoroughly until every piece of stuffing is moistened. Spread this mixture evenly over the chicken and sauce layer creating a consistent topping that will become golden and crispy.
- Bake to Perfection:
- Place the casserole in your preheated oven and bake for 30 to 35 minutes. You'll know it's done when the stuffing turns golden brown and the chicken reaches an internal temperature of 165°F. The sauce should be bubbling around the edges indicating it's hot throughout.

The secret ingredient in this casserole is really the Swiss cheese. My grandmother always insisted on using authentic Swiss cheese rather than substitutes and now I understand why. The distinct nutty flavor creates a depth that elevates this from a simple casserole to something truly memorable. Last Christmas I made this for our family gathering and my brother who typically avoids casseroles had three helpings.
Make Ahead Magic
This casserole shines as a make ahead meal. You can assemble the entire dish up to a day before cooking just cover tightly with plastic wrap and refrigerate. When ready to bake remove from the refrigerator 30 minutes before cooking to take the chill off and add about 10 minutes to the baking time. The flavors actually develop and improve with time making this perfect for busy households or when entertaining.
Smart Substitutions
This recipe welcomes adaptations based on what you have available. Turkey cutlets work beautifully in place of chicken breasts. Not a fan of Swiss? Gruyère provides a similar nuttiness while provolone offers a milder option. For a lighter version substitute Greek yogurt for the sour cream and use reduced fat soup. Gluten free stuffing mix works perfectly for those with dietary restrictions without compromising the texture or flavor.
Serving Suggestions
While this casserole stands beautifully on its own a simple green salad dressed with vinaigrette provides a fresh counterpoint to the richness. For a complete meal roasted asparagus or green beans complement the flavors without competing. If serving for company cranberry sauce offers a sweet tart contrast that elevates the entire dining experience. For casual family dinners serve in wide shallow bowls to capture all the delicious sauce.
