In a gallon ziplock bag mix together the flour, salt, pepper, garlic powder, and paprika.
Dredge chicken cutlets in flour and shake off any excess.
Heat a large pan over medium-high heat and add the butter and olive oil. Add the chicken cutlets to the pan and cook for 3-4 minutes on each side, until lightly golden brown and a thermometer registers 165℉. Remove to a plate and cover with foil.
Wipe out any burned flour bits (browned is ok), and add a bit more oil or butter if needed. Add the mushrooms and shallots and cook for 5-6 minutes, or until they are browned and have given up their moisture. Add in the garlic and cook for 1 more minute.
Add in the Marsala and reduce by half. Add in the chicken broth and continue to cook for 3-4 minutes. Add in the cream and chicken, and cook until heated through and the sauce is thickened. Garnish with fresh chopped parsley and serve.
