My son-in-law bought a prime rib for Christmas and I used this recipe. As many of the reviewers had used Montreal Seasoning, I bought some and mixed that in too. I made sure to have the roast at room temperature prior to cooking and to use a covered pan while cooking it. It came out perfect and everyone loved it. The smells coming out of the kitchen while it was cooking was enough to make everyone starving. Very easy and very good. Thanks.

I am very sorry that I wasted my time as well as my prime rib on this recipe. I had a 10lb roast (with bones...don't know if that makes a difference), after 45 minutes in the 500 degree oven all of our smoke detectors were going wacko (thank goodness our guests were family and therefore forgiving b/c there was a tone of smoke). We had to open several doors, etc to air it out. We put in a roasting pan and covered with foil and a ton if liquid got into the bottom of the oven (not sure how, we had it covered tightly and it fit in the pan). Needless to say, we shut the oven off at 55 minutes and never opened the door. After the 90 minutes with the oven off, the smoke had cleared but our roast was waaaay undercooked, at around 115-120 degrees. After the oven incident, we ended up re-wrapping and putting the grill on medium and trying to cook the roast in there. We finally got a decent temperature, but at that point our roast was pretty much shoe leather. Finally, and this may happen with all prime ribs, I am not really sure, this sucker started out one huge hunk of meat, it was 1/2 the size (lengthwise) when it came out of the oven...and I am not exaggarating....It was litterally half the size! Anyhow, next time I think we are going to order pizza for New Year's Eve, and when we want prime rib we will go to J. Alexander's (our favorite restaurant).

This was a very tasty dish. Note: garlic provided taste to the outside of the meat. You need to insert small slivers into the middle of the meat. Also, when changing the weight, it was difficult to adjust cooking times given the two stages of cooking. For 5 lbs we cooked for 45 mins, then let sit in the oven for 60 mins. This seemed to result in medium meat.

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 for me and I wouldn't recommend anyone to take a chance blowing a $50 piece of meat and a holiday meal on this one! I get far superior results with the method whereby you pack your roast in a bed of Kosher salt, cook high heat for 20-30 minutes then drop down to 325 degrees. Always tender and flavorful, and no surprises when it's time to eat!

Very good Convect at 325 25-30 min per pound.

I didn't have any garlic cloves so I mixed minced garlic in with the dijon mustard and spread it on, also I used montreal steak spice instead of the salt and pepper. I'm sure this would have been very good if I had used a 10lb roast but unfortunately I had a 2lb roast and I completely overcooked it. I set the oven temperature at 500 degrees to start and then tested the meat with a meat thermometer after 30 minutes. It was close to being rare at that point so I turned the oven temperature down to 375 degrees and kept it in for another half hour. When I took out my roast the meat thermometer reading was way above well done. What a disappointment for a person who likes it medium to medium rare! It was edible but not close to being as good as it could have been.

The best prime rib we ever tasted. We had perfect range of meat (medium to well done).

This is great! I made this on Christmas day and again New Years day. It is that good! Remember- 5 mins. per pound at 500 degrees. Use a thermomter for best results. I made a paste with the mustard- using minced garlic from a jar, and tons of Montreal Steak Seasonings (a favorite year round) and garlic salt. Very tasty! My husband hates roast beef- after a childhood full of bland, dry ones- and loves this. This is a keeper!!

Excellent! I put the roast out on the counter for 1 hour before putting it into the oven. (I cleaned the oven first.) 12# roast, I cooked 70 min. and turned it off. It was so good. Everybody loved it. I liked that this one was roasted with a cover. In the past I had done Prime Rib in an open roasting pan (as per other recipes) and my oven was always a MESS afterwards and it was always so smokey. I dind't have a bit of problem with smoke. I'll definitely do this again.

Well, I followed this recipe to a 't' but the meat still wasn't done enough and we like med.rare beef. Anyway, I ended up keeping the roast in the oven at 225 for about another 40 minutes and then it was fine. Only prob...guests had to wait for their Xmas meal. Another prob...even with a very clean oven, house still smoked up!
