Cooking Steps
About 1 hour before you’re ready to cook, remove prime rib from packaging; place on a baking sheet (larger side down) and allow to come to room temperature.
Adjust rack to middle position and preheat oven to 275 degrees.
Tent prime rib loosely with foil. Roast on middle rack until cooked to desired doneness, 1½-2 hours. Transfer to a cutting board to rest, at least 15 minutes.
Once prime rib has rested, slice and transfer to a serving platter. In a small bowl, combine mayonnaise, 1 tsp sugar, and as much horseradish paste as you like. Season with pepper. Serve with creamy horseradish aioli on the side.
