Chicken Gloria

Introduction

If you’re looking for a comforting and flavorful chicken dish that’s sure to impress, Chicken Gloria might just become your new favorite go-to recipe. Creamy, rich, and packed with savory flavor, this retro-inspired casserole is a beloved classic that’s stood the test of time. Chicken Gloria combines tender chicken breasts, a luscious mushroom sauce, and a cheesy, golden crust that makes each bite irresistibly delicious.

This dish is believed to have originated in American home kitchens during the 1950s and gained popularity through vintage community cookbooks and home economics classes. Often made with condensed soup and American cheese, the modern version gets an upgrade with simple from-scratch ingredients—while still keeping that nostalgic charm. It’s the perfect meal for cozy family dinners, potlucks, or even a make-ahead option for busy weeknights.

What sets this Chicken Gloria recipe apart is the use of fresh mushrooms and creamy Gruyère or Swiss cheese that melts beautifully, creating an indulgent, velvety sauce. The chicken remains juicy and tender thanks to a pre-sear before baking, and the entire dish is finished off in the oven until bubbly and golden brown. It’s hearty, flavorful, and bound to become a household favorite!

Ingredients

For the Chicken

• 4 boneless, skinless chicken breasts (about 2 lbs / 900 g)
• 1/2 cup (60 g) all-purpose flour
• 1 tsp salt
• 1/2 tsp black pepper
• 2 tbsp olive oil
• 2 tbsp unsalted butter

For the Mushroom Sauce

• 2 tbsp unsalted butter
• 1 small yellow onion, finely chopped
• 8 oz (225 g) fresh cremini or white mushrooms, sliced
• 2 cloves garlic, minced
• 1/4 cup (60 ml) dry white wine or chicken broth
• 1 cup (240 ml) heavy cream
• 1 cup (240 ml) chicken broth
• 1/4 cup (60 ml) sour cream
• 1/4 tsp ground nutmeg
• Salt and pepper, to taste

For the Topping

• 8 slices Gruyère or Swiss cheese (can substitute with mozzarella or provolone)
• 1/4 cup (25 g) grated Parmesan cheese
• 2 tbsp fresh parsley, chopped (for garnish)

Instructions

1. Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch (23×33 cm) baking dish and set aside.
2. Flatten the chicken breasts to an even thickness using a meat mallet or rolling pin between two sheets of plastic wrap. This ensures even cooking.
3. In a shallow dish, combine the flour, salt, and pepper. Dredge each chicken breast in the flour mixture, coating all sides and shaking off any excess.
4. In a large skillet, heat olive oil and butter over medium-high heat. Sear the chicken breasts for 3–4 minutes on each side until golden brown but not fully cooked through. Transfer the chicken to the prepared baking dish.
5. Lower the heat to medium and add an additional 2 tablespoons of butter to the same skillet. Sauté the onions for 2–3 minutes until translucent.
6. Add the sliced mushrooms and cook for 5–6 minutes, stirring occasionally, until they release moisture and start to caramelize.
7. Stir in the garlic and cook for another 30 seconds until fragrant.
8. Pour in the white wine or chicken broth to deglaze the pan, scraping up browned bits from the bottom. Simmer for 2 minutes to reduce slightly.
9. Stir in the heavy cream, chicken broth, sour cream, nutmeg, salt, and pepper. Bring to a gentle simmer and cook for 3–4 minutes, stirring often. The sauce should thicken slightly.
10. Pour the mushroom cream sauce evenly over the chicken in the baking dish, ensuring all pieces are well coated.
11. Top each chicken breast with a slice of Gruyère or Swiss cheese. Sprinkle Parmesan cheese over the entire dish.
12. Cover the baking dish with foil and bake for 20 minutes.
13. Remove the foil and continue baking for an additional 10–12 minutes, or until the cheese is bubbly and lightly browned and the internal temperature of the chicken reaches 165°F (74°C).
14. Garnish with freshly chopped parsley before serving.
15. Tip: Let the Chicken Gloria rest for 5 minutes after baking so the juices redistribute and the sauce thickens further.

Tips & Variations

Helpful Tips:

• Pound the chicken evenly: This ensures each breast cooks at the same rate and stays juicy.
• Don’t skip the searing step: It locks in flavor and gives the chicken a wonderful golden crust before baking.
• Use fresh mushrooms: They deliver better flavor and texture compared to canned mushrooms.
• Choose high-quality cheese: Gruyère or Swiss cheese adds richness and melts beautifully.
• Let it rest: Allow the casserole to sit for a few minutes after baking so the sauce can settle.

Variations:

• Use thighs instead of breasts: Boneless, skinless chicken thighs are also juicy and flavorful in this dish.
• Add spinach: Stir in a handful of fresh spinach to the sauce before pouring over the chicken for an added veggie boost.
• Make it spicy: Add a pinch of red pepper flakes to the cream sauce for a little heat.
• Upgrade the sauce: Try adding a splash of sherry or brandy with the wine for deeper flavor.
