Rub the seasoning mixture all over the prime rib roast, ensuring it is evenly coated.
Let the seasoned roast sit at room temperature for 30 minutes to absorb the flavors.

Using a roasting rack can help ensure even cooking.
Roast in the preheated oven for 45 minutes.
Use a meat thermometer to monitor the internal temperature for your desired doneness.
Turn off the oven and let the roast sit inside without opening the door for 1 hour.
This step allows the roast to continue cooking gently and retain its juices.
