Preheat the oven to 450 degrees F.

Rub the roast all over with the olive oil.

In a small bowl, combine the black pepper, salt, Herbes de Provence and garlic powder. Mix well. Rub the seasoning blends all over the roast.

Place the roast in a roasting pan with a rack, bone-side down. Cook the roast for 15 minutes, then reduce the oven temperature to 325 degrees F. Continue to cook until the meat thermometer reads 120 degrees F (medium-rare prime rib), about 1 hour and 15 minutes. Cooking time may varies, depending on the oven and weight of the roast.

Remove the roast from the oven and cover with a foil. Let the meat rest for 30 minutes. Slice and serve with your favorite side dishes.
