Tips & Variations
- For a different flavor, substitute dry sherry with white wine or chicken broth.
- Use other melting cheeses like Gruyère or Fontina if Muenster isn’t available.
- Adding fresh thyme or parsley to the sauce can enhance the aroma and taste.
- To make this dish gluten-free, replace all-purpose flour with a gluten-free flour blend for dredging and sauce thickening.
Storage
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven to keep the sauce creamy and chicken tender. Avoid microwaving to prevent the cheese from becoming rubbery.

Liquids & Dairy
- 1/4 cup dry sherry wine
- 1 cup chicken stock
- 1 1/2 cups heavy cream
- 8 ounces Muenster cheese, sliced
Instructions
- Prepare the chicken: Butterfly the chicken breasts and cut into eight pieces, each about 4 ounces. Mix the flour with kosher salt and white pepper in a bowl, then dredge the chicken pieces thoroughly in this seasoned flour.
- Preheat and ready dish: Spray a casserole dish with non-stick spray and preheat your oven to 375°F (190°C).
- Sauté chicken: Melt half the butter with half the olive oil in a pan over medium heat. Brown half of the dredged chicken pieces in this mixture. Transfer browned pieces into the casserole dish.
- Brown remaining chicken: Using the same pan, brown the remaining chicken pieces. Discard the fat from the pan and clean it to prepare for the next steps.
- Sauté mushrooms: In the cleaned pan, melt remaining butter and olive oil. Add sliced cremini mushrooms and sauté until browned and tender. Add mushrooms to the chicken in the casserole dish.
- Sauté onions and garlic: In the same pan, sauté the sliced sweet onion until soft, then add minced garlic and cook for about one minute until fragrant.
- Deglaze with sherry: Pour in the dry sherry wine and allow it to cook briefly to reduce slightly and infuse flavor.
- Make the sauce: Sprinkle flour over the onion and garlic mixture, stirring constantly. Gradually whisk in chicken stock and cook until the sauce thickens slightly. Then stir in heavy cream and heat the sauce until it bubbles gently.
- Combine and bake: Pour the prepared creamy sauce over the chicken and mushrooms in the casserole dish. Arrange slices of Muenster cheese evenly on top. Cover the dish.
- Bake and broil: Bake the covered casserole in the preheated oven for 20 minutes. After baking, remove the cover and broil the dish until the cheese topping is golden brown and bubbly, watching carefully to avoid burning.
Notes
- Butterflying the chicken ensures even cooking and tender pieces.
- Double dredging the chicken creates a crispier coating.
- Dry sherry adds depth to the sauce, but a dry white wine can be substituted if needed.
