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 freshly chopped parsley, for garnish

How to Make Chicken Gloria Casserole
Step 1: Preheat the Oven
Preheat your oven to 350°F (177°C). Lightly grease or line your 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 pieces and brown them on both sides (no need to cook through just yet). Transfer the browned chicken to a plate and set aside.
Step 4: Sauté Mushrooms
In the same skillet, melt the butter over medium-high heat. Add the sliced mushrooms, season with salt and pepper, and sauté until they’re golden brown. Pour in the sherry wine to deglaze the skillet, cooking for 1-2 minutes.
Step 5: Prepare the Sauce
Stir in the cream of mushroom soup into the skillet with mushrooms and sherry. Mix well until heated through.
Step 6: Assemble the Casserole
Arrange the browned chicken pieces in your prepared baking dish. Pour the mushroom sauce over them. Top each piece with a slice of Swiss or Muenster cheese.
Step 7: Bake
Cover your dish with aluminum foil and bake for about 30 minutes in your preheated oven. After this time, remove the foil and broil for an additional 1-2 minutes until the cheese is bubbly and lightly browned.
Step 8: Rest and Garnish
Take your casserole out of the oven and let it rest for about 5 minutes. Before serving, garnish it with freshly chopped parsley. Enjoy your delicious Chicken Gloria Casserole!

Common Mistakes to Avoid
When making Chicken Gloria Casserole, it’s easy to run into a few common pitfalls. Here are some mistakes to watch out for:
- Skipping the Seasoning: Neglecting to season the chicken properly can lead to bland flavors. Always remember to salt and pepper both sides generously.
- Overcooking the Chicken: Cooking the chicken fully before baking can result in dry meat. Brown it lightly instead and let it finish cooking in the casserole.
- Not Deglazing the Skillet: Failing to deglaze the skillet after sautéing mushrooms means losing rich flavor. Make sure to add sherry wine and scrape up any brown bits.
- Using Cold Ingredients: Starting with cold cream of mushroom soup can affect texture. Allow it to come to room temperature for a smoother sauce.
- Neglecting to Garnish: Forgetting the parsley garnish can make your dish look less appealing. A sprinkle adds a fresh touch and enhances presentation.
