Beef tenderloin is a cut of meat from the loin of a cow, known for its tenderness and rich flavor. It is one of the most sought-after cuts due to its low fat content and fine texture. Typically, it is sold whole or can be sliced into steaks, such as filet mignon. This cut is often prepared using methods like roasting, grilling, or pan-searing. Because of its delicate nature, it cooks quickly and is best served medium-rare to maintain its juiciness. Beef tenderloin is a popular choice for special occasions and fine dining.
