Creating Chicken Marsala can be straightforward if you follow these simple steps:

1. Prepare the Chicken: Start by patting the chicken breasts dry with a paper towel. Season both sides with salt and pepper.
2. Dredge in Flour: Spread the flour on a plate and coat each chicken breast, shaking off the excess flour.
3. Heat the Pan: In a large skillet, heat olive oil and one tablespoon of butter over medium-high heat until shimmering.
4. Cook the Chicken: Add the chicken breasts to the pan. Cook for about 4-5 minutes on each side or until they are golden brown and cooked through. Once done, transfer to a plate and tent with foil to keep warm.
5. Sauté the Mushrooms: In the same skillet, add the remaining tablespoon of butter, followed by the sliced mushrooms. Sauté until the mushrooms are browned and have softened, about 4-5 minutes.
6. Deglaze the Pan: Once the mushrooms are cooked, pour in the Marsala wine to deglaze the pan. Use a wooden spoon to scrape the brown bits from the bottom. Let it simmer for 2-3 minutes until slightly reduced.
7. Add Chicken Broth: Pour the chicken broth into the pan and continue to simmer for another 3-4 minutes. The sauce should thicken slightly.
8. Return Chicken to the Pan: Place the chicken breasts back into the skillet, allowing them to simmer in the sauce for an additional 2-3 minutes.
9. Garnish and Serve: Sprinkle the chopped parsley over the top for a fresh flavor boost.
