Fiance's family is coming over for baby Jesus's birthday and I'm going to make a standing rib roast. Anyone done the 200 degree first, then sear method? I'm thinking I should plan on 5 hours. Family is getting here at 6 and I'm serving the roast at 7. After letting it get to room temperature, I'll probably stick it in around 1:45.

One advantage of this method, of course, is that I can take the roast out and tent it at some point, then stick it back in. I'm just afraid that I might misjudge it and have family waiting.

Mine is done by pouring and rubbing in worcester shire sauce, then garlic power and pepper rub, finally slathering it with dijon mustard and laying some rosemary leaves on top. Next it goes into a large pan with 1.5 inches of rock salt in the bottom. I pack the remaining roast, sides and top, with abundant rock salt. Temp probe is inserted and it goes into a 550 degree oven for 20 minutes. After 20 minutes I turn down the temp to 240 degrees and check it every half hour until the internal temp is 130 degrees. At that point, I pull it out of the oven and cover with foil. It rests for 30 minutes, after which I break off the rock salt crust, brush off any remaining and slice on the cutting board. This nets me a moist, juicy medium rare prime rib.

Just got done with 30 lbs of boneless prime rib roast in the smoker. Started at 11:30pm last night 170F, hit 115F by 4:30am. Dropped it to 150F, got up to 124F by 6:45am before I broiled in the oven for 5 min and brought them in to work.

At 200F, you'll probably hit temp in 3.5-4 hrs, wouldn't bother with letting it come to room temp, just season and go.

:confused:
How large of a standing rib roast? Time depends somewhat on size.
As far as resting it at the end, if you cook at 350, the internal temp will rise by about 5 degrees. If cooking at 250, maybe 2 degree rise.

I think it's 20-25 minutes per pound at 250.
