When it comes to cooking the perfect prime rib, slow and low is the way to go. At a temperature of 250 degrees Fahrenheit, you can achieve a tender and juicy prime rib that is sure to impress your guests. The key to success is to use a meat thermometer to ensure that the internal temperature reaches your desired level of doneness.
For a medium-rare prime rib, aim for an internal temperature of 135 degrees Fahrenheit. This typically takes about 30 minutes per pound at 250 degrees. For a medium prime rib, aim for 140 degrees Fahrenheit, which will take about 35 minutes per pound. And for a well-done prime rib, aim for 150 degrees Fahrenheit, which will take about 40 minutes per pound.
Calculating Cooking Time for Your Prime Rib
Calculating the cooking time for your prime rib is easy with our handy chart. Simply take the weight of your prime rib in pounds and multiply it by the recommended cooking time per pound at 250 degrees. For example, if you have a 5-pound prime rib and you want it medium-rare, you would calculate 5 x 30 minutes = 150 minutes, or 2.5 hours.
Remember to always let your prime rib rest for at least 15-20 minutes after cooking to allow the juices to redistribute and ensure a moist and flavorful end result. Serve with your favorite sides and enjoy a delicious meal that will have everyone coming back for seconds.
