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

1. Prepare Chicken: Place the chicken breasts between two sheets of plastic wrap and pound them to an even thickness for even cooking.
2. Season Flour: In a shallow bowl, mix the flour, salt, black pepper, and garlic powder. Dredge each chicken breast in the flour mixture, shaking off any excess.
3. Heat Oil and Butter: In a large skillet, heat the olive oil and butter over medium-high heat until the butter is melted and bubbly.
4. Cook Chicken: Add the chicken breasts to the skillet and cook for 5-7 minutes on each side, or until golden brown and cooked through. Remove chicken from the skillet and set aside.
5. Sauté Mushrooms: In the same skillet, add the sliced mushrooms. Sauté for about 4-5 minutes, or until they are browned and tender.
6. Add Marsala Wine: Pour the Marsala wine into the skillet, scraping up any browned bits from the bottom. Allow it to simmer for 2-3 minutes.
7. Add Chicken Broth: Pour in the chicken broth and stir to combine. Let the sauce simmer for an additional 5 minutes to reduce slightly.
8. Return Chicken to Skillet: Add the cooked chicken back into the skillet, spooning the sauce over each piece. Cook for another 2-3 minutes until the chicken is heated through.
9. Garnish: Remove from heat and sprinkle with chopped parsley before serving.
