Chicken Gloria is the kind of cozy main dish I crave on chilly nights – juicy chicken under a blanket of creamy mushroom sauce and gooey Swiss cheese. This family favorite turns an ordinary weeknight into something special with just a few pantry ingredients and a casserole dish.
My first Chicken Gloria was a last minute guest meal and everyone asked for the recipe by the end of dinner. Now it is my reliable standby for comforting make-ahead meals and potlucks.
Ingredients
- Boneless skinless chicken breasts: These form the flavorful base of the dish Choose big pieces and cut them yourself for juicier results
- Salt and black pepper: Essential for building flavor right from the start Freshly ground is best for pepper
- Olive oil: Gives a golden sear to the chicken Use a fruity or light style for best taste
- Butter: Adds richness to mushrooms and sauce Use real butter for maximum flavor
- Fresh mushrooms: Sliced mushrooms add earthiness Baby bella or white button mushrooms hold their shape well
- Garlic: Finely minced garlic brings aromatic warmth to the sauce Choose firm cloves for best punch
- All-purpose flour: Helps thicken the sauce and gives the chicken a delicate crust Opt for unbleached if possible
- Dry sherry: Lends depth and a touch of sweetness A decent supermarket bottle is perfect
- Heavy cream: Gives the sauce its signature silkiness Avoid ultra-pasteurized cream if you can for luxe results
- Swiss cheese: Melts over the top for creamy nutty goodness Thinly sliced is best so it melts evenly
- Red pepper flakes: Optional but give a tiny spark of heat Always taste to check your heat level
- Fresh parsley: Brightens and adds a splash of color Use as a garnish just before serving
Step-by-Step Instructions
- Prepare the Oven and Chicken:
- Set your oven to 375 degrees Fahrenheit making sure a rack is in the top third so the cheese browns later. Halve your chicken breasts lengthwise so you have six thinner cutlets. Season both sides with salt and pepper then dredge lightly in flour shaking off extra so each piece has a delicate flour coating only.
- Sear the Chicken:
- Pour olive oil and one tablespoon butter into a large skillet over medium-high heat. Wait until the butter foams and just turns golden then add the chicken pieces in batches. Cook each side about three to four minutes so a light crust forms but do not cook them through. As they finish layer them into a casserole dish large enough to hold them in a single layer.
- Cook the Mushrooms:
- Add another tablespoon of butter to the same skillet over medium heat. Toss in the mushrooms making sure they spread out as much as possible. Stir every minute or two to encourage browning and let their liquid evaporate fully. This should take about five minutes. Spread them among and on top of the chicken in your casserole.
- Make the Sauce:
- Melt the rest of the butter in the pan you used for mushrooms. Stir in minced garlic and let it sizzle just thirty seconds until fragrant but not browned. Sprinkle in the last two tablespoons of flour and stir constantly for a minute to remove raw taste. Slowly pour in sherry whisking to loosen brown bits from the pan followed gradually by the heavy cream. Add a whisper of red pepper flakes if you like some heat. Let this bubble for two to three minutes until it coats a spoon. Taste and adjust with more salt and pepper if needed.
- Assemble and Bake:
- Pour your cream sauce evenly over the chicken and mushrooms. Drape a slice of Swiss cheese over each chicken piece making sure it touches the sauce underneath so it melts evenly. Cover the dish tightly with foil.
- Bake and Finish:
- Slide the dish into your hot oven for twenty minutes then carefully uncover and broil it for two to three minutes watching closely so the cheese turns bubbly and golden but never burns. Let it rest five minutes once out of the oven so the sauce settles. Scatter with fresh chopped parsley and bring straight to the table.

Every time I make this my favorite part is how the mushroom cream sauce perfumes the kitchen – it always reminds me of Sunday dinners when my whole family would fight over who got the cheesiest serving.
Storage Tips
Store leftovers in an airtight container in the fridge for up to three days The sauce thickens a bit when cold so add a splash of broth or milk when reheating to bring everything back to a silky texture
Ingredient Substitutions
No dry sherry on hand Try a dry white wine or chicken broth for a milder flavor If you only have mozzarella or provolone cheese instead of Swiss those melt well too and give a milder finish

Cultural Touch
While this dish is classic American comfort food at heart the combination of mushrooms cream and cheese hints at French influences The recipe became popular as a retro casserole in the mid twentieth century when Swiss cheese and sherry made home cooks feel just a little fancy
Commonly Asked Questions
- → How can I ensure the chicken stays juicy?
Sear the chicken until just browned, not fully cooked through; finish cooking with the sauce in the oven to lock in moisture.
- → What can I use instead of dry sherry?
Dry white wine or chicken broth can be substituted, but each gives a slightly different underlying flavor.
- → How do I prevent the cheese from burning?
Broil just until the cheese is bubbly and lightly golden, watching closely during the last few minutes.
- → Can I use a different cheese?
Yes, provolone or mozzarella offer a mild melt similar to Swiss, though both alter the outcome slightly.
- → What sides pair well with this dish?
Mashed potatoes, rice, or buttered noodles work perfectly to soak up the creamy sauce.
- → How do I store leftovers?
Place cooled portions in an airtight container and refrigerate for up to three days. Reheat gently.
