Ingredients
For the Chicken

- Kosher salt, to taste
- Freshly ground black pepper, to taste
For the Sauce
- 3 tablespoons olive oil
- 2 tablespoons unsalted butter
- 8 ounces mushrooms, thinly sliced

For Topping
- 6 slices Swiss or Muenster cheese
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 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 pieces and brown on both sides (no need to cook through at this stage). Transfer the browned chicken to a plate and set aside.
Step 4: Sauté Mushrooms
In the same skillet, melt butter over medium-high heat. Add thinly sliced mushrooms, season with salt and pepper, and sauté until golden brown. Deglaze the skillet by pouring in sherry wine; cook for 1-2 minutes until slightly reduced.
Step 5: Prepare the Sauce
Stir the cream of mushroom soup into the skillet with mushrooms and sherry. Mix well until heated through.
Step 6: Assemble the Casserole
Arrange browned chicken in your prepared baking dish. Pour mushroom sauce over chicken pieces. Top each piece with a slice of Swiss or Muenster cheese.
Step 7: Bake
Cover with aluminum foil and bake for 30 minutes. Afterward, remove foil and broil for an additional 1-2 minutes until cheese is bubbly and lightly browned.
Step 8: Rest and Garnish
Remove from oven; let casserole rest for 5 minutes. Garnish with freshly chopped parsley before serving.

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: Not seasoning the chicken well can lead to bland flavors. Always season your chicken with kosher salt and freshly ground black pepper before cooking.
- Overcooking the chicken: Cooking the chicken fully in the pan can make it dry. Brown the chicken just until golden; it will finish cooking in the oven.
- Using cold ingredients: Cold ingredients can affect cooking times and texture. Ensure your cream of mushroom soup and other components are at room temperature before mixing.
- Neglecting to deglaze: Forgetting to deglaze the skillet can cause a loss of flavor. Always add sherry wine after sautéing mushrooms to capture all that delicious goodness.
- Not letting it rest: Cutting into the casserole immediately can result in a mess. Let it rest for a few minutes after baking for better serving.
Refrigerator Storage
- Store leftover Chicken Gloria Casserole in an airtight container.
- It will keep well in the refrigerator for up to 3-4 days.
Freezing Chicken Gloria Casserole
- To freeze, place it in a freezer-safe container or wrap it tightly with plastic wrap and aluminum foil.
- The casserole can be frozen 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 20-25 minutes until warmed through.
- Microwave: Place individual servings in a microwave-safe dish and heat for 1-2 minutes, checking frequently.
- Stovetop: Reheat on low heat in a skillet, stirring occasionally until heated throughout.
