  • 4 boneless, skinless chicken breasts
  • 1/2 cup all-purpose flour
  • 3 tablespoons olive oil
  • 2 tablespoons unsalted butter
  • 8 oz cremini or white mushrooms, sliced
  • 1/2 cup dry white wine
  • 1 (18 oz) can of creamy mushroom soup
  • 6 slices of Gruyère cheese
  • 2 tablespoons fresh chives, finely chopped, for garnish
  • Sea salt and freshly ground black pepper, to taste


  1. Begin by preheating your oven to 350°F and have a 9×13-inch baking dish ready.
  2. Season the chicken breasts generously with sea salt and freshly ground black pepper on both sides. Lightly coat them with flour, shaking off any excess.
  3. In a large skillet over medium heat, warm the olive oil. Once hot, sear the chicken until it’s beautifully golden on both sides, but remember it doesn’t need to cook through at this stage, as it will finish cooking in the oven. Transfer the seared chicken to your prepared baking dish.
  4. In the same skillet, add the butter, and increase the heat to medium-high. Toss in the sliced mushrooms and season them with a pinch of sea salt and black pepper. Sauté until they turn a lovely golden brown. Pour in the dry white wine and let it simmer for 1 to 2 minutes. Then, stir in the creamy mushroom soup, ensuring everything is well combined, and let it heat through.
  5. Pour this delectable sauce over the chicken in the baking dish. Now, layer the Gruyère cheese slices on top, creating a melty, golden blanket of goodness.
  6. Cover the baking dish with foil and bake it for 30 minutes. Then, remove the foil and switch your oven to broil. Let the cheese brown to perfection, which should take 1 to 2 minutes under the broiler.
  7. Allow the dish to rest for 5 minutes before serving. Garnish it with fresh chives for an extra burst of flavor. This Creamy Mushroom Delight is ready to be savored. Enjoy your culinary creation!
