Swiss Chicken Casserole
This Swiss Chicken Casserole is a cozy, easy dinner that’s great for busy nights. It features layers of tender chicken, a creamy sauce, melted Swiss cheese, and golden stuffing on top. Everything bakes together in one dish until golden and bubbly, giving you that mix of creamy, savory, and crisp in every bite.
Ingredients
- 2 pounds boneless skinless chicken breasts, (about 4-6 small breasts), patted dry
- ½ teaspoon salt
- ½ teaspoon black pepper
- 1 teaspoon garlic powder
- 6 slices Swiss cheese
- 10.5 ounce can cream of chicken soup
- ½ cup sour cream
- ½ cup low-sodium chicken broth
- 1 teaspoon Dijon mustard (optional)
- ½ teaspoon onion powder (optional)
- ¼ teaspoon dried thyme leaves (optional)
- 1 box (6 ounces) dry seasoned stuffing mix
- 6 Tablespoons melted unsalted butter
Optional Garnish:
- 1 Tablespoon chopped fresh parsley
Instructions
- Heat Oven: Preheat oven to 375 °F. Lightly coat a 9×13-inch baking dish with cooking spray.
- Even Out Chicken: Arrange 2 pounds boneless skinless chicken breasts in the dish in a single layer. If some pieces are thicker, lightly pound them with a meat mallet or rolling pin to about ¾-inch for even cooking. Sprinkle with ½ teaspoon salt, ½ teaspoon black pepper, and 1 teaspoon garlic powder.
- Layer Cheese: Lay 6 slices Swiss cheese over chicken, overlapping slightly so it’s covered.
- Mix Sauce: In a bowl, whisk together 10.5 ounce can cream of chicken soup, ½ cup sour cream, ½ cup low-sodium chicken broth, 1 teaspoon Dijon mustard (optional), ½ teaspoon onion powder (optional), and ¼ teaspoon dried thyme leaves (optional) until smooth. Spoon sauce evenly over chicken and cheese.
- Top With Stuffing: In another bowl, toss 1 box (6 ounces) dry seasoned stuffing mix with 6 Tablespoons melted unsalted butter until coated. Sprinkle it evenly over the top.
- Bake: Bake uncovered for 30-40 minutes, until chicken reaches 165°F in the thickest part and the stuffing is golden. If topping starts to brown too quickly, loosely cover with foil during the last 10-15 minutes. For thinner cutlets (about ½ inch), start checking around 25 minutes.
- Rest and Serve: Let casserole rest for about 5 minutes before serving so the sauce thickens slightly. Optionally, garnish with 1 Tablespoon chopped fresh parsley, then serve.
