prime rib

Probably a dumb question for this site but I value the expert opinion. Have a 14lb. prime rib for tomorrow. If I cut it into 2 7lb. roasts will that shorten the cooking time assuming they are both in the oven at the same time?

The best thing you can do is to use an instant read thermometer. Theoretically yes, it should be faster, but the sear phase of the cook is the same. The good thing about roasts is they hold very well, even wrapping the pan in foil for two hours and setting it near your warm stove and blasting it in the oven at 450F for 10 minutes before serving will yield good results.

I'd leave it whole. As kuan said, use an instant read thermometer for accurate results.

Yes two small roasts will cook faster. It’s a good idea if you have a lot of people who I sits on an end piece, or need to cook the meat to two different temperatures. It also gives you the opportunity to flavor them differently if you like.
