What is the ideal internal temperature for medium-rare beef?

The ideal internal temperature for medium-rare beef is recognized as 135°F (57°C). Cooking beef to this temperature allows for the desirable pink coloration and juicy texture associated with medium-rare steaks, where the meat retains a significant amount of natural juices and tenderness. At this temperature, the meat reaches a point where it's safe to eat while maintaining a robust flavor profile.

It's important to note that the guidelines for cooking beef are based on considerations of food safety and quality. Medium-rare beef may still show signs of red in the center and is often preferred by steak enthusiasts for its balance of flavor and texture. Cooking it beyond this temperature can lead to a more well-done product, which may lose some of its juiciness and tenderness. Therefore, 135°F is the target for achieving the medium-rare designation in cooking.
