Tools & Equipment Needed

• Nonstick cooking spray
• Mixing bowl
• Whisk
• Spatula

Optional helpful tools:

Step-by-Step Instructions

1. Preheat the oven to 350°F. Spray a 9×13-inch baking dish with nonstick cooking spray.
2. Prepare the sauce. In a mixing bowl, combine 1 (10.5 oz) can condensed cream of chicken soup, 1 cup chicken broth, and 2 cloves minced garlic. Whisk until smooth.
3. Season the chicken. Sprinkle both sides of the 6 boneless skinless chicken breasts evenly with 1/4 cup grated Parmesan cheese, 1/4 teaspoon salt, and 1/4 teaspoon ground black pepper.
4. Arrange chicken. Place the seasoned chicken breasts evenly in the prepared baking dish.
5. Add Swiss cheese. Top each chicken breast with 2 slices of Swiss cheese, covering them fully.
6. Pour sauce. Evenly pour the cream of chicken mixture over the chicken and cheese. Use a spatula to spread it across the entire dish.
7. Add stuffing layer. Sprinkle the dry 8 oz seasoned stuffing mix evenly over the top, completely covering the surface.
8. Drizzle butter. Pour the 1/2 cup melted unsalted butter evenly over the stuffing layer.
9. Bake covered. Cover the baking dish tightly with aluminum foil. Bake for 40 minutes.
10. Finish baking uncovered. Remove foil and continue baking for 15–20 minutes more, until the stuffing is golden brown and the chicken reaches an internal temperature of 165°F.
11. Rest and garnish. Let the casserole rest for 5 minutes before serving. Garnish with 2 tablespoons chopped fresh parsley if desired.

Flavor Profile

Swiss Chicken Casserole is rich, creamy, and savory with layered textures. The chicken stays tender and juicy beneath the melted Swiss cheese, which provides a mild nutty flavor. The cream of chicken sauce blends with garlic and broth to create a smooth, velvety base.

The stuffing topping absorbs butter as it bakes, becoming golden and crisp on top while remaining slightly soft underneath. That contrast between creamy sauce and crunchy topping makes every bite satisfying and balanced.
