Beef tenderloin is a long, lean muscle from the loin of a cow, known as the most tender cut of beef because it's a non-weight-bearing support muscle. It has a fine, buttery texture and is prized for its melt-in-your-mouth quality. Common uses include steaks like filet mignon, roasts such as chateaubriand, and dishes like Beef Wellington.
