Deglaze pan drippings with the port wine mixture, bring to a rapid boil and cook until slightly reduced. Stir in creme fraiche, season with salt and pepper and stir in the medallions.
Arrange beef medallions on plates with beans, potato gratin and sauce. Sprinkle with coarsely ground pepper and serve.
