Prime Rib Roast - Au Jus - Horseradish Sauce

1. In a small bowl combine Dijon mustard, thyme, garlic, salt and pepper. Spread generously on the roast.
2. Preheat oven to 500 degrees Fahrenheit.
3. How long to cook the roast in the oven? That is easy! Multiply the total roast poundage by 5 minutes. Be as accurate as possible.

Example: the total weight of the prime rib is 5.53 pounds. Multiply 5.53 (pounds) times 5 (minutes) which equals = 27.65. This means the roast will cook in the oven for (27,65) or almost 28 minutes at 500 degrees F. After 28 minutes immediately turn oven temperature off. DO NOT OPEN OVEN DOOR DURING THE NEXT 2 HOURS THE ROAST IS STILL COOKING. This method will cook any size prime rib roast to perfection…. Rare to medium rare inside the way it should be with a crispy outer crust. Serve beef prime rib with au jus and horseradish sauce.
