• 1 ½ cups herbed stuffing mix

How To Make Swiss Chicken Casserole 

Step 1: Prepare

Preheat the oven to 350°F (175°C) and coat a casserole dish or baking dish with a bit of nonstick spray. Salt and pepper each chicken breast and put one slice of Swiss cheese on each piece of chicken. Place each breast in the prepared casserole dish.

Step 2: Make the cheese sauce

Melt the butter in a pot over medium heat. Add the flour to the melted butter and let it cook for 1 minute. Add the chicken broth, salt, and pepper, and whisk well to combine. Cook until the sauce thickens, then add the sliced Swiss cheese or shredded Swiss cheese and stir. Once melted together and smooth, spread the sauce over the chicken. 

Step 3: Bake and Serve

Top the chicken with the dry stuffing mix and bake, covered for 40 minutes. Remove the cover and cook for another 20 minutes until the stuffing is toasted and the chicken is cooked through.

Serve the chicken warm with any leftover sauce, along with any sides you want. Enjoy!

Expert Tips

• Use cream of chicken soup or cream of mushroom soup instead of the Swiss cheese sauce. I'll do this simple swap if I don't have a lot of time to prepare dinner.
• Add a teaspoon of garlic powder and onion powder to the cheese sauce for a more savory flavor.
• Top the chicken with crushed Ritz crackers instead of the dry stuffing mix. I've done this a number of times, and I can't decide which topping is better - they're both so delicious! 
• Try making the recipe with boneless chicken thighs instead of boneless chicken breasts.
• Serve the chicken with a dollop of sour cream for an extra creamy texture and tangy flavor.

FAQS About This Swiss Chicken Casserole

How long can I store leftovers?

Store leftovers in an airtight container or in the baking dish with a lid for 3-4 days in the refrigerator.

Can I use chicken thighs instead of chicken breasts?

Yes! Boneless, skinless chicken thighs work great and add extra juiciness. Just make sure they're cooked to an internal temp of 165°F before serving.

What can I use instead of Swiss cheese?

You can swap Swiss for mozzarella, provolone, or even cheddar if that’s what you have. Swiss gives it that distinct flavor, but any melty cheese works well.

Can I make this casserole ahead of time?

Definitely. You can assemble the casserole, cover it, and refrigerate it up to 24 hours in advance. When you're ready to bake, just add a few extra minutes to the cook time.

Does this casserole freeze well?

Yes, Swiss chicken casserole freezes great. Let it cool completely, wrap it tightly, and freeze for up to 2 months. Thaw in the fridge overnight and reheat in the oven until warmed through.
