Filet Mignon is a steak cut of beef taken from the smaller end of the tenderloin, or psoas major of the cow carcass, usually a steer or heifer. In French this cut is always called filet de bœuf, which translates in English to beef fillet.
Filet mignon may be cut into 1- to 2-inch (2.5 to 5 cm) thick portions, then grilled and served as-is. One also may find filet mignon in stores already cut into portions and wrapped with bacon. High heat is the usual method for cooking the filet mignon, either grilling, pan frying, broiling, or roasting.
