Contrary to popular belief, the word Châteaubriand does not refer only to a cut of beef, but to a method used to grill or roast a thick cut of beef tenderloin. The steak was originally prepared by a chef named Montmireil in 1822 for a French author, diplomat, and statesman Francois René Vicomte de Chateaubriand.

When served in France, Châteaubriand will always be accompanied by a sauce – most often either a traditional red wine sauce or Béarnaise sauce. The steak is usually served with a side of roasted new potatoes or tiny chateau potatoes.
