Ingredients
Chicken
- 3 large boneless, skinless chicken breasts (cut into 6 thin cutlets)
- Salt and pepper, to taste
- ⅓–½ cup all-purpose flour (for dredging)
- 1 tablespoon olive oil
- 2–3 tablespoons butter
Sauce
- 8 oz cremini or white mushrooms, sliced
- ½ medium onion, diced
- 3–4 garlic cloves, minced
- ½ cup dry sherry (or dry white wine)
- ¾–1 cup chicken broth
- ½–1 cup heavy cream or half-and-half (or cream of mushroom soup as a substitute)
Topping
- 6 slices Muenster or Swiss cheese
- Fresh parsley, chopped (for garnish)
How to Make It Step-by-Step
1. Preheat the oven.
Start by preheating your oven to 350°F (175°C). While that’s heating up, grab a 9×13-inch baking dish and set it aside. You’ll want it ready for the chicken once it’s seared.
2. Prepare the chicken.
Season the chicken cutlets generously with salt and pepper, then dredge them lightly in flour. This will give them a nice, golden crust when you sear them in the pan. The flour also helps to thicken the sauce later on.
3. Sear the chicken.
In a large skillet, heat the olive oil and 1 tablespoon of butter over medium-high heat. Once it’s hot, add the chicken cutlets and sear them until golden brown on both sides, about 3–4 minutes per side. You don’t need to cook them all the way through at this point—just give them a beautiful golden crust. Once done, transfer the chicken to the prepared baking dish.
4. Make the mushroom sauce.
In the same skillet, melt the remaining butter. Add the diced onion and minced garlic, and sauté until they’re soft and fragrant, about 2 minutes. Then, add the sliced mushrooms and cook them until they’re browned and their moisture has evaporated, about 5 minutes. This step is crucial because it brings out the earthy flavor of the mushrooms.
5. Deglaze the pan.
Once the mushrooms are browned, pour in the dry sherry (or white wine), stirring to deglaze the pan and lift any flavorful browned bits off the bottom. Let it simmer for 1–2 minutes to allow the alcohol to cook off and the flavors to concentrate.
6. Add the liquids.
Next, stir in the chicken broth and cream (or cream of mushroom soup for a shortcut). Let this simmer for a few minutes until the sauce thickens slightly. Taste it and adjust the seasoning with more salt and pepper if needed.
7. Assemble the casserole.
Pour the mushroom sauce evenly over the seared chicken in the baking dish. Be sure to cover each piece with the sauce for maximum flavor. Then, top each chicken cutlet with a slice of Muenster cheese.
8. Bake and broil.
Cover the baking dish with foil and bake for 30 minutes. Then, remove the foil and broil for 1–3 minutes until the cheese is bubbly and golden brown. This step adds a wonderful crispy texture to the cheese and gives it that perfect finishing touch.
9. Garnish and serve.
Before serving, sprinkle the casserole with freshly chopped parsley for a burst of color and freshness. Then, slice it up and serve!
Tips for Best Results
- Don’t overcook the chicken: Searing the chicken until golden is key. Overcooking it in the pan will make it dry. The baking step will finish cooking the chicken to perfection.
- Let the sauce thicken: Simmer the sauce just long enough to thicken it slightly before pouring it over the chicken. You want it creamy, not too runny.
- Use high-quality cheese: Muenster or Swiss cheese is traditional, but feel free to try other cheeses like mozzarella, Gouda, or Fontina for a twist.
- Add herbs for extra flavor: Fresh thyme, rosemary, or even a pinch of dried oregano can add a nice herby flavor to the sauce.
Ingredient Substitutions & Variations
- Use chicken thighs: For a juicier, richer result, chicken thighs are a great option. Just be sure to adjust the cook time slightly as thighs take a bit longer to cook than breasts.
- Sherry substitute: If you don’t have dry sherry, dry white wine works just as well. Alternatively, you can use chicken broth with a splash of vinegar for a similar effect.
- Cream of mushroom soup: If you’re in a rush or want an even quicker dish, you can substitute the heavy cream with a can of cream of mushroom soup. It makes for a delicious, shortcut sauce.
- Cheese options: While Muenster and Swiss cheese are classic choices, you can also try Swiss, Gouda, or even Fontina for a creamy, melty topping.
Serving Suggestions
Chicken Gloria pairs beautifully with a variety of side dishes. Here are a few of my favorites:
- Mashed potatoes: Creamy mashed potatoes are always a hit with this rich, savory casserole. The potatoes soak up the sauce and complement the chicken perfectly.
- Steamed vegetables: Lightly steamed broccoli, green beans, or carrots add a fresh and healthy contrast to the creamy dish.
- Rice or pasta: Whether it’s fluffy white rice, buttered egg noodles, or a simple side of pasta, these carb-heavy sides balance out the richness of the casserole.
- Crusty bread: For a little something extra, serve with warm, crusty bread to soak up the creamy sauce.
Pairing Ideas (Drinks, Sides, etc.)
- A crisp white wine like Chardonnay or Sauvignon Blanc would pair perfectly with the richness of the dish.
- For a non-alcoholic option, serve with sparkling water or a light iced tea for a refreshing contrast to the creamy casserole.
- A simple green salad with a tangy vinaigrette would balance the heaviness of the casserole and add some freshness to the meal.
How to Store and Reheat Leftovers
- Refrigeration: Store leftovers in an airtight container in the fridge for up to 4 days. This dish actually gets even better the next day as the flavors continue to meld.
- Freezing: If you want to freeze it, let the casserole cool completely, then wrap it tightly and freeze for up to 2 months. When you’re ready to eat, thaw overnight in the fridge, then reheat in the oven at 350°F until hot and bubbly.
- Microwave: For a quick reheat, microwave individual servings for 1–2 minutes, but keep in mind the sauce might separate a bit when reheated.
Make-Ahead and Freezer Tips
- Make-ahead: You can assemble the entire casserole earlier in the day, cover it, and refrigerate it until you’re ready to bake. This is a great option for busy days when you want to have a meal ready to go.
- Freezer: This casserole freezes well once baked. Just be mindful that the cream sauce may slightly separate after freezing, but it will still taste delicious. Just reheat gently!
Common Mistakes to Avoid
- Overcooking the chicken: This is key to keeping the chicken juicy and tender. Be sure not to overcook it during the searing step.
- Too much flour for dredging: Use just enough flour to lightly coat the chicken—too much flour can result in a thick, gummy sauce.
- Not letting the sauce thicken enough: The sauce should be thick enough to coat the chicken and provide that rich, creamy texture. Let it simmer a bit longer if it seems too thin.
Frequently Asked Questions (FAQ)
- Can I use chicken thighs instead of breasts?
- Yes! Chicken thighs are juicier and more flavorful, but you may need to adjust the cooking time slightly.
- Is sherry necessary for the sauce?
- Not at all. You can substitute sherry with dry white wine, chicken broth, or even a splash of vinegar.
- Can I prepare this ahead of time?
- Absolutely! You can assemble the casserole ahead of time, refrigerate it, and bake it later.
- Can I freeze Chicken Gloria?
- Yes, freeze after baking, then thaw and reheat when you’re ready to enjoy it.
