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

The ideal cooking temperature for medium-rare beef is typically considered to be around 135°F (57°C). At this temperature, beef reaches a state where it is warm red in the center, tender, and juicy. This temperature allows for the development of a flavorful crust, while the interior remains succulent and retains its natural moisture. Furthermore, it is necessary for safety and quality, as beef at this temperature is adequately cooked but still has a slightly less firm texture compared to higher temperatures, which aligns with the characteristics desired for medium-rare.

The temperatures listed as other choices fall outside the common understanding of medium-rare. Temperatures below 135°F would not reach the midpoint of this doneness level, leading to a rawer texture, while higher temperatures would begin moving towards medium doneness, which is typically characterized by more significant firming and a lack of the pink, juicy center that defines medium-rare.
