For the Chicken Marinade:

  • 4 boneless, skinless chicken breasts
  • 1/2 cup all-purpose flour
  • Salt and pepper to taste
  • 2 tablespoons olive oil

For the Creamy Mushroom Sauce:

  • 8 oz cremini or button mushrooms, sliced
  • 4 cloves garlic, minced
  • 1 cup chicken broth
  • 1 cup heavy cream
  • 1/2 cup grated Parmesan cheese
  • 1 teaspoon dried thyme
  • 1 teaspoon dried rosemary
  • Salt and pepper to taste

For Assembly:

  • 1 cup shredded mozzarella cheese
  • Fresh parsley, chopped, for garnish


Chicken Marinade:

  1. Prepare Chicken Breasts:
    • Pat the chicken breasts dry with paper towels. In a shallow bowl, combine the flour, salt, and pepper. Dredge each chicken breast in the flour mixture, ensuring an even coating.
  2. Sear the Chicken:
    • In a large skillet, heat olive oil over medium-high heat. Sear the chicken breasts until golden brown on both sides. Remove from the skillet and set aside.

Creamy Mushroom Sauce:

  1. Sauté Mushrooms and Garlic:
    • In the same skillet, add sliced mushrooms and minced garlic. Sauté until the mushrooms are golden brown and the garlic is fragrant.
  2. Deglaze with Broth:
    • Pour in the chicken broth, scraping the bottom of the skillet to release any flavorful bits. Allow the broth to simmer for a few minutes.
  3. Introduce Cream and Cheese:
    • Lower the heat and add heavy cream, Parmesan cheese, thyme, rosemary, salt, and pepper. Stir until the sauce thickens and the cheese is fully melted.
  4. Combine with Chicken:
    • Return the seared chicken breasts to the skillet, ensuring they are coated in the creamy mushroom sauce. Simmer for an additional 5-7 minutes until the chicken is cooked through.


  1. Preheat Oven:
    • Preheat your oven to 375°F (190°C).
  2. Transfer to Casserole Dish:
    • Transfer the chicken and creamy mushroom sauce to a greased casserole dish. Arrange the chicken breasts evenly.
  3. Add Mozzarella Cheese:
    • Sprinkle shredded mozzarella cheese over the chicken breasts, ensuring a generous layer that will melt into golden perfection.
  4. Bake to Perfection:
    • Bake in the preheated oven for 20-25 minutes or until the cheese is bubbly and lightly browned.
  5. Garnish and Serve:
    • Remove from the oven, garnish with chopped fresh parsley, and serve the Chicken Gloria Casserole warm.

Cook Notes

  • Flour Coating Tip: Shake off excess flour from the chicken breasts before searing to prevent the sauce from becoming too thick.
  • Mushroom Selection: Feel free to use a mix of cremini and button mushrooms for a depth of flavor.
  • Fresh vs. Dried Herbs: While dried thyme and rosemary work well in this recipe, you can use fresh herbs if available, adjusting quantities to taste.
  • Cheese Choice: Experiment with different cheeses like Gruyère or Swiss for a unique twist on the classic recipe.


Sun-Dried Tomato Twist:

  • Add a burst of sweetness and tanginess by incorporating chopped sun-dried tomatoes into the creamy mushroom sauce.

Spinach Infusion:

  • Introduce fresh spinach to the mushroom sauce for a vibrant, nutrient-packed addition.

Crispy Bacon Crunch:

  • Enhance the dish with the irresistible crunch of crispy bacon bits scattered over the melted cheese.

Keto Versions

Almond Flour Coating:

  • Replace all-purpose flour with almond flour for a keto-friendly alternative in the chicken marinade.

Xanthan Gum Thickening:

  • Use xanthan gum as a thickening agent in the sauce instead of flour to keep it low-carb.

Cauliflower Rice Base:

  • Serve the Chicken Gloria Casserole over cauliflower rice for a low-carb option.

Low-Carb Versions

Vegetable Noodle Bed:

  • Layer zucchini or spaghetti squash noodles beneath the chicken for a low-carb noodle alternative.

Broccoli Boost:

  • Mix in bite-sized broccoli florets to add a nutritious, low-carb element to the casserole.

Swapped Cream Options:

  • Opt for lower-carb cream alternatives such as coconut cream or unsweetened almond milk.
