  1. Preheat the oven to 500 degrees F (260 degrees C).
  2. Make slits all over the roast by pricking with a small knife. Insert slivers of sliced garlic. Season the roast with salt and pepper, then spread generously with mustard. Place on a rack in a roasting pan, and cover.
  3. Roast for 60 minutes in the preheated oven. Turn off oven. Leave oven closed, and do not peek for 90 minutes. The internal temperature of the meat should be at least 140 degrees F (60 degrees C) for medium-rare, or 155 degrees F (68 degrees C) for medium.


  • Tip
  • Aluminum foil can be used to keep food moist, cook it evenly, and make clean-up easier.

I used a 5 lb roast. I cooked it at 400 for 60 minutes and then let it sit for 45. It was a little bit more than medium. I would probably cook for 45 and let it sit for 45 next time.

I loved this recipe. I do not understand how some people could have gotten anything but exceptional results with this method. Now I used a Whopper of a Prime Rib…an 18-pounder. I compensated ...

I made this for the first time on Christmas Eve 2002. I put it in the preheated oven just as we left home for Xmas Eve services and man did the house smell amazing when we returned home. Inste...

This recipe is absolutely awesome! For a previous reviewer, the reason your roast came out raw was because you did not let your roast come to room temperature before cooking. You need to let i...

Like many others, I followed the recipe and ended up with barely cooked beef that wasn't particularly flavorful or tender. I know this receipe does work for some folks and their ovens, but not ...

My family loves this recipe. I do recomend adjusting the temperature for a smaller/larger roast to 500 degrees for 5 min/lb. Ex. 5 lb roast is 25 min at 500 degrees. Also make sure your roa...
