Ingredients

• 6 boneless, skinless chicken breasts

• ¼ cup grated Parmesan cheese

• ¼ teaspoon salt

• ¼ teaspoon ground black pepper

• 12 slices Swiss cheese

• 1 (10.5‑ounce) can cream of chicken soup

• 1 cup chicken broth

• 2 garlic cloves, minced

• ½ cup melted butter

• 8-ounce package Stove Top stuffing mix

• 1 teaspoon fresh minced parsley (optional, for garnish)

Step‑by‑Step: How to Make Swiss Chicken Casserole

1. Preheat & prep the baking dish
   Preheat oven to 350 °F (175 °C). Spray a 9×13‑inch baking dish with nonstick cooking spray (or lightly oil it).

2. Mix sauce base
   In a large mixing bowl, combine the cream of chicken soup, chicken broth, and minced garlic. Stir until smooth and well blended.

3. Season the chicken
   Place the chicken breasts in the bottom of the prepared baking dish. Sprinkle grated Parmesan cheese, salt, and pepper over the breasts. Flip the chicken to coat both sides with the seasoning.

4. Add Swiss cheese layer
   Take 2 slices of Swiss cheese per chicken breast and lay them over the seasoned chicken so that each piece is covered in cheese.

5. Pour the sauce
   Carefully pour the soup‑broth‑garlic mixture over the cheese and chicken, spreading it gently so that it covers and seeps around the layers.

6. Top with stuffing mix
   Sprinkle the dry Stove Top stuffing mix evenly over the entire top of the casserole—covering the cheese and sauce layer.

7. Add melted butter
   Evenly drizzle the melted butter on top of the stuffing mix. The butter helps crisp the topping and meld the flavors.

8. Cover and bake
   Cover the dish with aluminum foil and bake in the preheated oven for about 40 minutes.

9. Uncover & finish baking
   Remove the foil and bake an additional 15–20 minutes to allow the stuffing top to brown and the chicken to finish cooking. Use a meat thermometer to ensure the internal temperature of the chicken reaches 165 °F (75 °C).

10. Garnish & serve
    Optionally sprinkle with fresh minced parsley before serving. Serve hot and enjoy.

Helpful Tips

• Let the chicken rest at room temperature for 10 minutes before baking so it cooks more evenly.

• Use thin or evenly sized breasts so nothing overcooks while others catch up.

• If your stuffing mix seems too dry or thick, you can loosen it slightly by mixing in a tablespoon or two of extra melted butter or broth before topping.

• For extra flavor, you can sauté the minced garlic in a little butter before mixing into soup/broth.

• Keep the foil loosely tented so steam doesn’t wash out crisping.

• In the final uncovered phase, keep an eye on the top so it doesn’t overbrown—if it does, you can tent it with foil again.

• Let the casserole rest 5 minutes after coming out of oven to let the sauce set a bit, improving slicing and service.

Substitutions and Variations

• Different cheese: You could use provolone, mozzarella, or even a Swiss‑cheddar blend in place of strictly Swiss slices.

• Cream of mushroom or celery soup: Swap in for cream of chicken if you prefer a different flavor base.

• Herbs: Add dried thyme, rosemary, or tarragon to the sauce mix for extra flavor.

• Gluten‑free option: Use a gluten‑free stuffing mix instead of Stove Top. Make sure soups are gluten‑free.

• Vegetables: Add a layer of sliced mushrooms, spinach, or broccoli under the cheese if you’d like extra veggies.

• Smaller portions: You can scale down to a smaller dish (e.g. 8×8) by halving ingredients.

• Crispier topping: After the final bake, switch to broil for 1–2 minutes (watch carefully) to crisp the stuffing top further.

Storage Instructions

• Refrigerator: Cover the cooled casserole with foil or airtight lid and store in the fridge for up to 3–4 days.

• Freezer: You can freeze individual portions in freezer-safe containers for 2–3 months. Thaw overnight in refrigerator before reheating.

• Reheating: Reheat in an oven at 325 °F (160 °C) covered, until warmed through (15–25 minutes depending on portion size). Remove the cover in the last few minutes to crisp up the topping again.

• Avoid sogginess: When reheating, avoid covering too tightly early—let some steam vent so topping doesn’t soften.

Nutritional Information

Here is an approximate nutrition breakdown per serving (assumes 6 servings total):

Serving Suggestions

• Serve alongside a crisp green salad with vinaigrette to cut through the richness.

• Steamed or roasted vegetables (green beans, asparagus, carrots) make excellent sides.

• Garlic bread or dinner rolls go nicely to mop up sauce.

• A light white wine or a sparkling water with lemon can help balance the richness.

• For a more casual setting, you can serve this over mashed potatoes or egg noodles so the creamy sauce blends in.

Frequently Asked Questions About Swiss Chicken Casserole

Can I use chicken thighs instead of breasts?
Yes — boneless, skinless chicken thighs will work, though they may require slightly longer baking time due to thicker portions. Monitor internal temp (165 °F) and adjust accordingly.

Can I prepare this ahead of time?
Definitely. Assemble the casserole (without pouring the butter on top) up to a day in advance. Store covered in the fridge, then add melted butter and bake fresh when ready. This helps maintain crispness on top.

What if I don’t have Stove Top stuffing mix?
You can use any dry seasoned stuffing mix, or make your own breadcrumb or cracker topping (mixed with butter, herbs, and a little Parmesan). Ensure it’s dry-ish so it crisps.

What’s the best way to keep the topping crispy?
To ensure a crispy topping, pour the melted butter evenly over the stuffing mix so it toasts properly during baking. After the initial covered bake, remove the foil and bake uncovered for the final 15–20 minutes. This allows moisture to evaporate and the topping to brown. For an extra crunch, broil briefly at the end—just keep a close eye to prevent burning.

Is this casserole freezer‑friendly?
Yes — once baked and fully cooled, you can portion and freeze for 2–3 months in airtight containers. Reheat from thawed state in oven, uncovered toward the end to restore the topping texture.

How can I lighten it up?
Use reduced‑fat soup, lower‑sodium broth, reduce butter slightly, or substitute leaner cheeses. You could also add more vegetables (e.g. mushrooms, spinach) to stretch the volume and reduce the per‑serving richness.
