I have a 15.5 lb prime rib. How long will it take?


  • Depends on how you do it. I just did an 18 lb prime rib. indirect setup. Started with dome at 500. Put on the prime and shut the vents down to achieve around 325. It took 3-1/2 hours to reach 125 internal. I double wrapped in foil and 2 towels. Put in a cooler and took across town for christmas dinner. Cut it about an hour after removing it from the egg. It was fantastic.
  • Forgot to mention. If you have a temp probe for the grate don't put it on until the dome cools below 400. I fried my probe.
  • Thanks I do have a guru Im doing it indirectly. No bones. I marinaded overnight in A1. Then today I putted it dry added butter with fresh rosemary spread all over and coated with course salt and wrapped it in bacon. It's sitting out for 4 hours it's at 40 degrees now I'll start it at 130 pm today and we we see how it goes
