Creating Olive Garden Chicken Marsala is straightforward if you follow these simple steps:

1. Prepare Chicken: Season the chicken breasts with salt and pepper. Dredge each piece in flour, shaking off the excess.
2. Heat Oil and Butter: In a large skillet, heat olive oil and butter over medium-high heat until hot.
3. Cook Chicken: Add the chicken breasts to the skillet. Cook for about 5-7 minutes on each side until golden brown and cooked through. Remove the chicken from the skillet and set aside.
4. Sauté Mushrooms: In the same skillet, add the sliced mushrooms. Sauté for 3-4 minutes until they are browned and tender.
5. Add Garlic: Stir in the minced garlic and cook for an additional minute, until fragrant.
6. Deglaze with Marsala: Pour in the Marsala wine, scraping the bottom of the skillet to release any browned bits. Let it simmer for 2-3 minutes to reduce slightly.
7. Add Chicken Broth: Stir in the chicken broth and bring to a simmer. Allow it to cook for another 5 minutes until the sauce thickens slightly.
8. Return Chicken: Return the cooked chicken to the skillet, spooning the sauce over the top. Cook for an additional 2-3 minutes to warm through.
9. Garnish and Serve: Sprinkle chopped parsley over the dish before serving.
