What is the ideal internal temperature for a perfectly cooked prime rib?

The ideal internal temperature for a perfectly cooked prime rib depends on the level of doneness desired. For a rare prime rib, the internal temperature should be at least 130°F – 135°F (54°C – 57°C), while a medium-rare prime rib should be cooked to an internal temperature of 135°F – 140°F (57°C – 60°C). It’s essential to use a meat thermometer to ensure the prime rib reaches a safe internal temperature.

It’s also important to note that the internal temperature of the prime rib will continue to rise after it’s removed from the oven, a phenomenon known as “carryover cooking.” This means that the prime rib may reach an internal temperature of 5°F – 10°F (3°C – 6°C) higher than the initial temperature reading. To account for this, it’s best to remove the prime rib from the oven when it reaches an internal temperature that’s 5°F – 10°F (3°C – 6°C) lower than the desired final temperature.
