How to Make Swiss Chicken Casserole

1. Preheat your oven to 375°F (190°C). Grease a 9×13 baking dish.
2. Arrange chicken breasts in a single layer in the dish. Season with salt, pepper, garlic powder, and onion powder.
3. Add Swiss cheese: Place 1–2 slices of Swiss cheese on top of each chicken breast.
4. Make the sauce: In a bowl, mix the cream of chicken soup and sour cream until smooth. Pour evenly over the cheese-covered chicken.
5. Add the topping: Sprinkle the dry stuffing mix over the top of the casserole. Drizzle melted butter evenly over the stuffing.
6. Bake uncovered for 35–40 minutes, or until the chicken is cooked through and the top is golden and crispy.
   (Internal temp of chicken should reach 165°F.)
7. Let rest for 5 minutes, garnish if desired, and serve warm.

Pro Tip: If the top browns too quickly, cover loosely with foil during the last 10 minutes.
