Do you have trouble accomplishing the perfect temperature for prime rib? I did, until now!
I can’t even begin to tell you how angry and disappointed I have been with overcooked prime rib made in my kitchen. When you spend that kind of money on a really good piece of beef you want it to be perfect, right?
I found a video of Method X from Food Wishes that walks you through the method in detail. This method works perfectly. The temperature of the prime rib when cooked is slightly warm but with the au jus, each bite is ah-mazing! So here is how it’s done.

Prime Rib Roast
How to Cook a Prime Rib
The prime rib must come to room temperature before roasting. This step is critical in the process. Overnight or a minimum of 6 hours.
In a small bowl, mix the softened butter, herbs, garlic, and black pepper together. Brush the butter mixture all over the roast. Place the prime rib in a roasting pan.
No matter what method you use (traditional or Method X), you should always have a probe style thermometer inserted so that the internal temperature can be monitored, to avoid any chance of over-cooking.
Set the probe alarm to 125 F. for medium-rare, and pull the roast from the oven even if there’s still time left on the timer when the meat thermometer reads 125 degrees F.
Now you use the formula for roasting. Multiply the exact weight times 5 minutes. For me, it was 5.81 x 5 = 29.05 minutes, which we round to 29. (The cooking time will be different for larger or smaller cuts of meat.)
Preheat the oven to 500 degrees. You will be roasting at high heat for the number of minutes you just calculated.
Place the roast in and cook for the exact amount of minutes required by the formula. After that time turn the oven off and set a timer for 2 hours. DO NOT OPEN THE DOOR FOR ANY REASON DURING THE 2 HOURS.
Remove the roast from the pan.
Remove the bones for easier slicing.
Look at that perfect medium-rare prime rib!
Slice and serve with a side of au jus. I hope you will be as impressed with yourself as I was when this beauty came out of my oven.
