Large 9 1/2 lb. Butt

eggandart

I have a whole large butt, 9.5 lbs.  I want to cook it whole, and low and slow 220.  But, never did one this big before.  How much time should I plan for?  Thanks.

1.5 hours a pound is a good guess but that is at 250-275 dome temp.  220 is a little low, wouldn't go below 250 and cook till 200 F internal temp.

@ OP-BGE has a temperature off-set for indirect cooks that will really affect your cook-time.  Basically the dome thermo reads 20-40*F hotter than the cooking grid.  Longer the  dome is shut the narrower the gap but as Tweev_tip and others have mentioned, go hotter and let the BGE do the work.  I still find around 2hrs/# with the dome 270*F (+/-) for pork butt cooks.  Plan long and if finished early you can always pack and wrap.

BTW-since you have cooked butts before, then you can scale what you have seen in the past to this adventure.

Thanks everyone...much appreciated...I'll take your advise and I think I'll go for the 250-275 and plan on @18-19 hours.  Of course, I'll have it done a couple hours before the party, wrapped and ready to pull.

I cooked a 10lb whole butt 2 weeks ago, I have a bbq guru digiq dx2 BGE unit and had the temp at 260 the whole time. It took 14 hours to get the internal to 200

I cook 8-9 lb butts a little differently.  I put it on the egg anywhere from 6:00 pm to 10:00 pm the night before and at a temperature of 210.  I have a Auber controller and do not have to worry about the temperature overnight.  The low temperature will get the meat to about 170-175 by morning.  I then raise the egg temperature to 250 for a while and then 275 for a while.  Doing this I can adjust my finish time.  It is easy with a pit controller.
