Preheat the oven to 350 degrees F.
Mix together the steak, cream, cheese, mushrooms, flour and onions, and then dump the ingredients into the bottom crust of the pie shell, fit into a pie plate. Cover with the second top crust. Cut slits in the top crust to vent and brush some melted butter over the top.
Bake until the crust is golden brown and the gravy is bubbling through the vents, 50 minutes to 1 hour. Let cool 5 to 10 minutes before serving.
