Ingredients Notes

The beauty of this Swiss Chicken Casserole lies in its simplicity. A few carefully chosen ingredients come together to create layers of flavor and texture.

Chicken breasts: Use boneless, skinless chicken breasts for this recipe. They’re lean, tender, and cook perfectly in the casserole. For extra juiciness, consider pounding them to an even thickness.

Swiss cheese: This is the star of the show! Its nutty, slightly tangy flavor complements the creamy sauce beautifully. Pre-sliced cheese works best for even layering.

Cream of chicken soup: This pantry staple forms the base of the casserole’s creamy sauce. For a lighter version, use the reduced-fat variety.

Sour cream: Adds a touch of tanginess and richness to the sauce. Greek yogurt can be substituted for a healthier option.

Stuffing mix: Provides a crispy, flavorful topping that ties the whole dish together. Any brand will work, but I recommend a savory variety for the best flavor.

Chicken broth: Moistens the stuffing mix and helps bring all the flavors together. Use low-sodium broth to control the salt level.

For equipment, you’ll need a large mixing bowl, a 9x13-inch baking dish, and aluminum foil for covering the casserole while it bakes.

How To Make This Swiss Chicken Casserole

This casserole is delightfully easy to make and perfect for beginners or seasoned cooks alike. Follow these steps for a perfect result every time.

Preheat your oven to 350°F (175°C) and lightly grease a 9x13-inch baking dish. Arrange the chicken breasts in a single layer in the dish, ensuring they’re evenly spaced for even cooking.

Next, mix the cream of chicken soup and sour cream in a large bowl until smooth. Spread this creamy mixture evenly over the chicken.

Layer the Swiss cheese slices over the sauce, ensuring the chicken is fully covered. The cheese will melt into the sauce, creating an irresistibly creamy layer.

In a separate bowl, combine the stuffing mix with the chicken broth. Stir until the stuffing is moistened, then sprinkle it evenly over the casserole. This topping will bake into a golden, crispy crust.

Cover the dish with aluminum foil and bake for 30 minutes. Remove the foil and bake for an additional 15-20 minutes, or until the stuffing is golden and the chicken is cooked through.

Let the casserole rest for 5 minutes before serving to allow the layers to settle. Enjoy the creamy, cheesy, crispy perfection with your favorite side dishes!

Storage Options

Leftovers? No problem! This Swiss Chicken Casserole stores beautifully, making it a great option for meal prep.

To refrigerate, transfer the cooled casserole to an airtight container. It will stay fresh for up to 3 days in the fridge.

For longer storage, freeze individual portions in freezer-safe containers. This way, you can grab a serving whenever you need a quick, homemade meal. It will keep for up to 3 months in the freezer.

To reheat, thaw frozen portions overnight in the fridge. Warm them in the microwave or bake in a 350°F oven until heated through.

Variations and Substitutions

This recipe is wonderfully adaptable, so feel free to customize it to suit your tastes.

Swap the Swiss cheese for mozzarella, provolone, or even cheddar if you prefer a milder or sharper flavor.

Use boneless, skinless chicken thighs instead of breasts for a juicier result. They cook up tender and flavorful every time.

Add a layer of sautéed mushrooms or steamed broccoli under the sauce for a veggie-packed twist.

Make it gluten-free by using gluten-free stuffing mix and cream soup. Be sure to check labels to confirm.

For a heartier casserole, add cooked rice or pasta as a bottom layer before adding the chicken. It’s a great way to stretch the dish for larger gatherings.
