Cutting Roast in half, effect on cooking time?

bigoz89 · January 2013

I have a 15lb standing rib roast that I am cooking today. It is about 17.5 inches long which is just slightly larger than my egg. If I cut the roast in half, and cook both halves at the same time, will that impact cooking time? I was planning on going 230-250 for about 6.5 to 7 hours until I get to med-rare but that was before I got the roast in my possession and saw the length.

Any thoughts? Thanks.

Happy New Year!

At Christmas I cooked 2 - 5 rib, bone in roast, raise grid, direct at 275 and it took 3 hours. Happy New Year! Enjoy!

It is not the same kind of roast, but with pork butts, you can base the time on the largest single roast. Plus a little lagniappe according to some folks, but I think time is based on the largest single one.

It's really the diameter of the roast that determines the cook-time once you get a good sized roast. Here's a great link about that whole topic-
