Let's get to work.
Cooking Instructions
- 1
First preheat oven to 500°F. While that is warming up let's do the math. For this purpose we will use the roast I have here. It is 11.2 lbs.
- 2
Let's do the math. 5 minutes per pound. 11.25 × 5 = 56.25 minutes. Now we round up to the nearest minute. So our time will be 57 minutes of cooking time
- 3
Now let's rub our roast with the garlic butter.
- 4
Sprinkle with your desired herbs. Can be anything from salt and pepper, to a prime rib rub. Again your choice.
- 5
Now we cook it in oven for exactly the calculated time. 57 minutes. Once the time has finished. Shut oven off. Set timer for 2 more hours. DO NOT OPEN OVEN. This is extremely important or it will not be cooked properly.
- 6
Once the 2 hours has finished. Your roast is ready to serve. I debone it before cutting.
- 7
IMPORTANT: The roast must be at room temperature before starting this process. It is recommended to leave roast on counter for approximately 6 hours.

Cooking time formula:“To calculate your cooking time, multiply the exact weight of the roast by 5. Round the resulting number to the nearest whole number. The rib is cooked at 500 degrees F for exactly that many minutes. For example, for a 6 pound roast: 6x5=30, so cooking time is 30 minutes. Turn the oven off and wait 2 hours before opening the oven door.” Oanh Luong -

Prime Rib Roast Prime Rib Roast
This is an Easter favorite for us, since these drop in price by 60%.Please note: I typically figure 20 minutes per pound for cooking times to have a roast done at med-rare to medium doneness. This includes the time cooking at the higher temps. So if I need to cook the roast for 3 hours, 90 minutes will be at the high temps, and then the remaining 90 min will be done at the lower temp.Steven Minogue
