For the Casserole
• Chicken Breasts – The star protein that keeps this dish hearty; chicken thighs can be used for added flavor.
• Salt & Pepper – Essential seasonings; adjust according to your taste preference.
• Flour – Perfect for dredging; gives the chicken a lovely golden crust. Gluten-free flour is a great substitute!
• Olive Oil – For frying the chicken, contributing to that beautiful browning; can be swapped with a neutral oil if needed.
• Butter – Richness in the sauce; divided for frying and combining with other ingredients; margarine can work if you prefer.
• Cremini Mushrooms – Adds depth and texture with their earthy flavor; substitute with button mushrooms for a milder taste.
• Garlic – An aromatic enhancer for your sauce; fresh garlic is best, but adjust to your preference for intensity.
• Dry Sherry – It adds complexity to your sauce; if you don’t want to use alcohol, opt for chicken broth instead.

• Muenster Cheese – Melts beautifully to create that delectable topping; try using Swiss cheese or Gruyère for a unique twist.

For the Topping
• Muenster Cheese – Essential for that gooey, melty finish; consider using mozzarella or cheddar for different flavor profiles.

Step‑by‑Step Instructions for Chicken Gloria

Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C), making sure to place the rack in the top third position. This will ensure an even cook while also providing that delightful, golden finish on your Chicken Gloria casserole when it’s time to broil.

Step 2: Prepare the Chicken
Slice chicken breasts into thin cutlets, then season them generously with salt and pepper. Dredge each cutlet in flour, ensuring an even coating. This will enhance the browning process during frying, creating a delicious golden crust that’s perfect for your Chicken Gloria casserole.

Step 3: Sear the Chicken
In a large skillet, heat olive oil and 1 tablespoon of butter over medium heat. Once the butter has melted and the mixture is shimmering, add the chicken cutlets in batches. Fry for about 3-4 minutes on each side, until they are lightly browned but not fully cooked through. This step will infuse your chicken with flavor.

Step 4: Transfer Chicken to Casserole
Carefully place the seared chicken cutlets in a 9×13 inch casserole dish, arranging them in a single layer for even cooking. This will be the base of your Chicken Gloria, allowing the flavors to meld beautifully as it bakes in the oven.

Step 5: Sauté the Mushrooms
Using the same skillet, add the remaining 2 tablespoons of butter and heat over medium-high. Once the butter has melted, add in the cremini mushrooms. Sauté for about 5 minutes until they are nicely seared and have released their moisture, adding a rich flavor to the casserole.

Step 6: Make the Creamy Sauce
In the skillet with sautéed mushrooms, add minced garlic and cook for an additional minute until fragrant. Then, stir in a couple of tablespoons of flour, cooking it for a minute to remove the raw flavor. Gradually whisk in dry sherry and heavy cream, stirring continuously until the mixture thickens and becomes smooth, signaling that the sauce is ready.

Step 7: Assemble the Casserole
Pour the creamy sauce over the chicken and mushrooms in the casserole dish, ensuring an even coating. Then, top the entire dish with slices of Muenster cheese, allowing for that gooey, melty perfection when baked. This will give the Chicken Gloria casserole its iconic cheesy finish.

Step 8: Bake the Casserole
Cover the casserole dish with aluminum foil, then place it in the oven. Bake for approximately 20 minutes, allowing the chicken to finish cooking and the flavors to meld. Once this time is up, carefully remove the foil to prepare for the final broiling step.

Step 9: Broil for Golden Perfection
Switch the oven to broil, monitoring closely as you return the casserole to the oven. Broil for about 2-4 minutes until the cheese is bubbling and golden brown. Keep a close eye to prevent burning, ensuring your Chicken Gloria is the showstopper of the meal.

Step 10: Let it Rest
Once the cheese is beautifully browned, remove the casserole from the oven and allow it to rest for a few minutes. This will help the layers settle for easier serving, making your Chicken Gloria casserole a comforting and hearty dish ready for family and friends.

Chicken Gloria Variations & Substitutions

Feel free to unleash your creativity and customize this delicious casserole to match your taste preferences and dietary needs!

Dairy-Free: Use coconut cream and a dairy-free cheese alternative for a rich, creamy taste that’s completely lactose-free.
Switching to these ingredients opens the door to new flavors while keeping the comforting essence intact.
Gluten-Free: Substitute regular flour with almond flour or a gluten-free all-purpose blend for dredging the chicken.
This small change makes the dish accessible to those with gluten sensitivities while still delivering that golden-brown crust.
Vegetable Boost: Toss in some sautéed spinach or zucchini alongside the mushrooms for a colorful, nutritious twist.
Adding these veggies not only brightens the dish but also sneaks in some extra vitamins without compromising flavor.
Kick of Spice: Enhance the flavor with a pinch of red pepper flakes or your favorite hot sauce for a spicy zing.
This subtle adjustment can take your casserole to a whole new level, perfect for those who love a hearty kick in their comfort food.
Different Cheeses: Experiment with gooey cheeses like mozzarella or sharp cheddar instead of Muenster for a flavor twist.
Each cheese brings its character, offering a delightful variation you can enjoy with every bite.
Herb Infusion: Add fresh herbs like thyme or rosemary during the sauce-making step to elevate the aromatic profile.
This addition not only enhances fragrance but wraps the casserole in herbaceous warmth, making it even more inviting.
Vegetarian Option: For a meatless version, use hearty portobello mushrooms instead of chicken, and increase the vegetables.
This is a fantastic way to craft a rich and filling dish while keeping it entirely plant-based.
Creamy Dream Substitution: Trade heavy cream for Greek yogurt for a lighter option without sacrificing creaminess.
Not only does this reduce calories, but it also adds a subtle tang that complements the dish beautifully.
