Ingredients
For the Chicken
- 3 chicken breasts, boneless and skinless, longitudinally halved
- 1/3 cup all-purpose flour
- Kosher salt, to taste
- Freshly ground black pepper, to taste
For Cooking
- 3 tablespoons olive oil
- 2 tablespoons unsalted butter
- 8 ounces mushrooms, thinly sliced

For the Sauce
- 1 can (18 ounces) cream of mushroom soup
- 6 slices Swiss or Muenster cheese
For Garnish
- 2 tablespoons fresh parsley, finely chopped

How to Make Chicken Gloria Casserole
Step 1: Preheat the Oven
Preheat your oven to 350°F (177°C). Lightly grease or line a 9×13-inch baking dish with parchment paper.
Step 2: Season and Prepare Chicken
Season both sides of the chicken breasts with kosher salt and freshly ground black pepper. Dredge each piece in flour, shaking off any excess.
Step 3: Brown the Chicken
Heat olive oil in a large skillet over medium heat. Add the chicken and brown on both sides (no need to cook through at this stage). Transfer the chicken to a plate and set aside.
Step 4: Sauté Mushrooms
In the same skillet, melt the butter over medium-high heat. Add the mushrooms, season with salt and pepper, and sauté until golden brown. Deglaze the skillet by pouring in the sherry wine and cooking for 1-2 minutes.
Step 5: Prepare the Sauce
Stir the cream of mushroom soup into the skillet with the mushrooms and sherry, mixing well. Heat until the sauce is evenly warmed.
Step 6: Assemble the Casserole
Arrange the browned chicken pieces in the prepared baking dish. Pour the mushroom and soup sauce over the chicken. Top each piece of chicken with a slice of Swiss or Muenster cheese.
Step 7: Bake
Cover the dish with aluminum foil and bake for 30 minutes in the preheated oven. After baking, remove the foil and broil for 1-2 minutes until the cheese is bubbly and lightly browned.
Step 8: Rest and Garnish
Remove the casserole from the oven and let it rest for 5 minutes. Garnish with freshly chopped parsley before serving. Enjoy your delicious Chicken Gloria Casserole!

How to Perfect Chicken Gloria Casserole
To create the best Chicken Gloria Casserole, consider these helpful tips that enhance both flavor and texture.
- Bold seasoning: Don’t be shy when seasoning your chicken. Generously season with salt and pepper to enhance the overall flavor.
- Fresh ingredients: Use fresh mushrooms rather than canned for a more vibrant taste and better texture in your casserole.
- Adjust cooking time: Keep an eye on your casserole while baking. If you are using larger chicken pieces, you may need to adjust cooking time slightly.
- Let it rest: Allowing the casserole to rest before serving helps the flavors meld together better.
- Experiment with cheeses: Feel free to mix different cheese varieties like cheddar or provolone for added flavor depth.

Best Side Dishes for Chicken Gloria Casserole
Complementing your Chicken Gloria Casserole with side dishes can make your meal even more enjoyable. Here are some fantastic options:
- Steamed Broccoli: This nutrient-rich vegetable pairs well with casseroles and adds color to your plate.

- Coleslaw: A crunchy coleslaw gives a refreshing contrast, making your meal feel light and balanced.
Common Mistakes to Avoid
When making Chicken Gloria Casserole, it’s easy to overlook some key steps. Avoid these common mistakes for the best results.
- Skipping the seasoning: Neglecting to season the chicken can lead to bland flavors. Always use kosher salt and freshly ground black pepper on both sides.
- Not browning the chicken: Failing to brown the chicken before baking can result in a less flavorful dish. Take the time to sear it in olive oil for added depth.
- Ignoring the deglazing step: Not deglazing the skillet after cooking mushrooms can waste flavor. Pour in sherry wine and scrape up those tasty bits from the bottom.
- Using cold ingredients: Adding cold ingredients to your casserole can affect cooking times. Ensure your cream of mushroom soup is at room temperature before mixing it in.
- Overbaking the casserole: Leaving the casserole in too long can dry it out. Keep an eye on it while broiling to achieve that perfect bubbly cheese without burning.
Storage & Reheating Instructions
Refrigerator Storage
- Store leftovers in an airtight container.
- Chicken Gloria Casserole will keep well in the refrigerator for up to 3 days.
Freezing Chicken Gloria Casserole
- Allow the casserole to cool completely before freezing.
- Use a freezer-safe container or wrap it tightly with aluminum foil; it will last for up to 3 months.
Reheating Chicken Gloria Casserole
- Oven: Preheat your oven to 350°F (177°C). Cover with foil and heat for about 20 minutes.
- Microwave: Place a serving in a microwave-safe dish, cover, and heat on medium power for 2-3 minutes, stirring halfway through.
