How to Make Chicken Gloria Casserole Step-by-Step Instructions
1. Prepare the Chicken
- Halve chicken breasts lengthwise so they cook evenly.
- Lightly dredge each piece in all-purpose flour, shaking off any excess.
2. Sear the Chicken
- In a large skillet, heat olive oil and 1 tablespoon butter over medium heat.
- Add the chicken pieces in batches and cook until lightly golden on both sides, about 2–3 minutes per side.
- Transfer to a casserole dish.
3. Cook the Mushrooms
- In the same skillet, melt the remaining butter.
- Add the sliced mushrooms and sauté until tender and golden, about 5–6 minutes.
- Season lightly with salt and pepper.
4. Make the Sauce
- Pour in the sherry wine and let it simmer for 1–2 minutes, scraping up browned bits from the pan.
- Stir in the cream of mushroom soup and whisk until smooth.
- Let the mixture bubble gently for 2–3 minutes until slightly thickened.
5. Assemble the Casserole
- Pour the mushroom sauce evenly over the chicken in the casserole dish.
- Lay slices of Swiss or Muenster cheese over the top to cover.
6. Bake
- Preheat oven to 350°F (175°C).
- Bake uncovered for 25–30 minutes, or until the cheese is melted and bubbly, and the chicken reaches an internal temperature of 165°F.
7. Garnish and Serve
- Sprinkle fresh parsley over the top before serving.
Serving and Decoration
Chicken Gloria Casserole is hearty enough to stand on its own but pairs well with simple sides:
- Rice or Noodles: Serve over fluffy white rice, egg noodles, or mashed potatoes to soak up the sauce.
- Vegetables: Roasted broccoli, steamed green beans, or a crisp salad balance the richness.
- Bread: Crusty bread is perfect for scooping up the creamy sauce.
Storing Chicken Gloria Casserole
- Refrigerator: Store leftovers in an airtight container for up to 3–4 days.
- Freezer: Assemble the casserole without baking, cover tightly, and freeze for up to 2 months. Thaw overnight in the fridge before baking.
- Reheating: Warm in the oven at 325°F until heated through, or reheat gently in the microwave.

Tips and Tricks for Success
- Don’t Overcook Chicken While Searing: The chicken will finish cooking in the oven, so just aim for a light golden crust.
- Slice Mushrooms Evenly: Thin, uniform slices cook more evenly and look better in the sauce.
- Use Good Cheese: A higher-quality Swiss or Muenster will melt creamier and taste richer.
- Double the Sauce: If you love extra creamy casseroles, double the soup and wine mixture.
