So is that an actual prime cut of beef? Everybody calls them prime rib even though the technical name is a standing rib roast. I know Costco specializes in choice beef for most of their stuff.[/quote]
It has the sticker, yep.

So, how do you all cook a prime rib roast?
I’m lazy. The only way I’ve ever done it is to buy the pre-seasoned prime rib kits from Costco and follow the direction. The directions are something like cook it in the oven for 20 minutes at 500F then drop the temperature to 250 and cook for another two hours. It does always come out terrific. Better than the prime rib I had at a fancy restaurant on friday night.[/quote]
This is very similar to how I cook all of my beef roasts, but I’ll keep it at 500 for a bit longer if it is a large roast and then just turn the oven off and KEEP THE DOOR CLOSED for a few hours.
I have a chart somewhere with the times per pound. I season with a light coat of olive oil and liberal amounts of Montreal Steak Seasoning, which is basically coarse salt and pepper. Works well for other type of beef roasts too.
This will be my Christmas dinner as well. jjackkrash’s way sounds better than mine, but I lack a rotisserie.
Ronco Super Showtime Pro. I’ve had a 22 pound rib roast in it. Leg of lamb is fantastic in it as well. My wife picked it up a while back and I love it.
