Ingredients Notes

The magic of Swiss Chicken Casserole lies in its simple yet delicious ingredients. Here’s what you’ll need and why each one is essential to the dish.

• Boneless, skinless chicken breasts – The foundation of the casserole. You can use thighs if you prefer a juicier bite. If using pre-cooked chicken (like rotisserie), just reduce the baking time slightly.
• Swiss cheese – The star ingredient! Its mild, nutty flavor pairs beautifully with the creamy sauce. You can substitute with provolone or mozzarella for a different taste.
• Cream of chicken soup – This helps create a creamy, flavorful base. If you prefer homemade, a simple mixture of chicken broth, heavy cream, and seasonings works just as well.
• Sour cream – Adds richness and tanginess to the sauce, balancing the flavors. Greek yogurt is a great alternative if you want a lighter option.
• Seasoned stuffing mix – The crunchy topping that takes this dish over the top! If you don’t have stuffing mix, crushed Ritz crackers or breadcrumbs with melted butter work beautifully.
• Butter – Helps the topping get golden and crispy. For an extra depth of flavor, try browning the butter before mixing it with the stuffing.

If you have a 9x13-inch baking dish and a mixing bowl, you’re all set to make this casserole!

How to Make This Swiss Chicken Casserole

Making Swiss Chicken Casserole is as easy as layering and baking! Here’s a step-by-step guide to ensure it comes out perfectly every time.

Start by preheating your oven to 350°F (175°C). Lightly grease a 9x13-inch baking dish to prevent sticking.

Step 1: Layer the Chicken and Cheese

Arrange the chicken breasts in a single layer in the baking dish. If they are thick, you can slice them in half for even cooking. Next, place the Swiss cheese slices directly over the chicken, covering as much as possible.

Step 2: Make the Creamy Sauce

In a bowl, mix together the cream of chicken soup and sour cream until well combined. Spread this mixture evenly over the chicken and cheese. The sauce will keep the chicken moist and infuse it with rich flavor.

Step 3: Add the Crunchy Topping

Sprinkle the stuffing mix evenly over the top of the casserole. Then, melt the butter and drizzle it over the stuffing to ensure a golden, crispy topping.

Step 4: Bake to Perfection

Cover the dish with foil and bake for 40 minutes. Then, remove the foil and bake for another 10-15 minutes until the topping is golden brown and the casserole is bubbling. If using pre-cooked chicken, reduce the total baking time to 30-35 minutes.

Once baked, let the casserole rest for about 5 minutes before serving. This helps the sauce thicken and allows the flavors to meld together.

Storage Options

Swiss Chicken Casserole stores beautifully, making it great for leftovers or meal prep!

• Refrigerate: Store leftovers in an airtight container for up to 3 days. Reheat in the oven at 350°F until warmed through or microwave in short intervals.
• Freeze: Assemble the casserole but don’t bake it. Wrap it tightly in plastic wrap and aluminum foil, then freeze for up to 3 months. When ready to eat, thaw overnight in the fridge and bake as directed.
• Reheat: For best results, reheat in the oven at 350°F for about 20 minutes. This keeps the topping crispy. If microwaving, add a splash of broth or milk to prevent drying out.

Variations and Substitutions

One of the best things about Swiss Chicken Casserole is how customizable it is! Here are a few delicious ways to switch it up.

• Use Different Cheeses – Not a fan of Swiss? Try provolone for a milder taste, cheddar for a sharp contrast, or pepper jack for a little spice.
• Add Vegetables – Stir in cooked mushrooms, spinach, or broccoli for extra nutrition and flavor.
• Swap the Soup – Instead of cream of chicken, use cream of mushroom or cream of celery for a different twist.
• Try a Different Topping – Instead of stuffing mix, use crushed Ritz crackers, Panko breadcrumbs, or even crumbled cornflakes for a unique crunch.
• Make It Low-Carb – Skip the stuffing topping and use a sprinkle of parmesan cheese instead for a lower-carb version.

No matter how you make it, this Swiss Chicken Casserole is guaranteed to be a hit at your dinner table. Don’t be afraid to experiment and find your perfect version!
