What is the cooking time for prime ribs?

Cooking time for prime rib depends on the desired doneness and the thickness of the prime rib. Here are the general guidelines for roasting a prime rib in the oven:

Rare: 15-17 minutes per pound

Medium-rare: 17-20 minutes per pound

Medium: 20-25 minutes per pound

Medium-well: 25-30 minutes per pound

Well-done: 30-35 minutes per pound

These times are approximate, so it's best to use a meat thermometer to check the internal temperature of the prime rib to ensure it's cooked to your desired doneness. The recommended internal temperature for prime rib is:

Rare: 120-125 degrees Fahrenheit (49-52 degrees Celsius)

Medium-rare: 125-130 degrees Fahrenheit (52-54 degrees Celsius)

Medium: 130-135 degrees Fahrenheit (54-57 degrees Celsius)

Medium-well: 135-140 degrees Fahrenheit (57-60 degrees Celsius)

Well-done: 145 degrees Fahrenheit or higher (63 degrees Celsius or higher)

It's important to note that the timing can vary depending on the specific cut and size of the prime rib, so it's always good to check the internal temperature to ensure it's cooked to your liking.
