Heat the Skillet: Add the butter to a large skillet and melt over medium high heat.
Cook the Chicken: Season chicken breasts on both sides with salt and pepper. Place chicken breasts in skillet and cook on both sides, about 3 to 5 min per side or until no longer pink inside, time depends on thickness of your breasts. Since the breast is fairly thin, it should cook faster. Transfer the chicken to a plate.
CooktheMushrooms: Add the onion and garlic to the skillet and cook for a couple minutes until onion is translucent and soft. Add the mushrooms and stir. Season mushrooms generously with salt and pepper. Let them cook for about 5 minutes, stirring occasionally. When they are cooked to your liking, add the wine and deglaze the pan by scraping the bottom of the skillet. All those brown bits are flavor!
Finish the Sauce: Sprinkle the flour over the mushrooms and stir for another minute just to remove the raw flour taste. Next, add the cream, stir and cook for 3 minutes, stirring occasionally or until sauce reduces a bit and thickens. Taste for seasoning and adjust with salt and pepper as needed. Add the chicken back to the skillet and spoon sauce over the chicken.
Finish and Serve: Garnish with parsley and serve hot.
This chicken and mushroom dish could be served over noodles or rice, or just enjoyed on its own with a nice crusty bread.
This chicken with the mushroom sauce will last in the fridge up to 3 days if wrapped well or stored in an airtight container. To extend the shelf life, I recommend freezing it, wrapped well or in an airtight container, and it will last anywhere from 4 – 6 months.
