Prime Rib - Foolproof

READY IN: 5hrs 40mins
Recipe by 1hotpotato

My wife got this recipe from her aunt. This has to be one of the best ways to cook a prime rib. We have always used a 10 to 12 pound prime rib roast and it comes out perfect everytime. The trick is to not open the oven at all. We literally tape the oven closed so the kids won't accidentally peak in on the roast.

The best method of roasting a prime rib. I use Montreal Steak seasoning instead of salt and pepper, otherwise I follow recipe exactly.
