Prep the Chicken: Slice the chicken breasts in half to create four thin cutlets. Pound them slightly if you need extra stress relief.
Coat the Chicken: Mix flour, salt, black pepper, and garlic powder in a shallow dish. Dredge each cutlet in the mixture.
Sear to Perfection: Heat olive oil and butter in a large skillet over medium heat. Cook the chicken for 4–5 minutes per side until golden.
Remove and Rest: Transfer the chicken to a plate. Try not to eat it yet.
Sauté the Mushrooms: Add more butter to the same pan. Cook the mushrooms for 5 minutes until browned. Stir in garlic and cook for another minute.
Deglaze with Marsala: Pour in the Marsala wine and let it simmer for 2–3 minutes until slightly reduced. Enjoy the heavenly aroma.
Build the Sauce: Stir in chicken broth, cream (if using), and thyme. Simmer for 5 minutes until thickened.
Reunite the Chicken: Return the chicken to the pan, coat in sauce, and let it simmer for 3 more minutes.
Garnish & Serve: Sprinkle with fresh parsley and serve with pasta, potatoes, or straight from the pan.
