At 4.99/lb it seems like a reasonable decision for Christmas dinner...soooo, I picked up a 9.8 lb. bone in roast. I could use some advice regarding cooking it on the E325. What temp. for the Genesis?How long/lb.? Drip pan under roast or under grates?
TIA
I would start by putting it on a rack today, in the refrigerator with some salt, cover it with cheese cloth and leave it until the night before cooking.
Night before I cradle it, and put some salt and pepper in the cradle cut and it goes back in the fridge.
I slow cook mine until desired IT with a pit temp around 200 to 225. IT for my and my family is 122 to 125 IT. Then I pull it, tent it, crank up the heat and finish it with 5 mins or so at max heat. An oven set to 500F will also work but it makes a bunch of smoke inside.
As far as the E325, I think that's three burner front control without a sear?
I would put it on a rack, in a roasting pan and try to raise it up away from the cooking grates a couple of inches.
If you have a cast iron griddle that fits front to back I'd put that over the center burner.
I would preheat with all burners on high and get lid temp to 350F, then shut off the two outside burners and put the roast on. I'm guessing lid temp will settle in around 275F, but it might be lower if its cool and breezy. I'd roast it anywhere from 225 to 275F until it hits your desired IT.
If you are going to finish it on the E325, I'd foil tent it in the pan and bring it inside for 15 mins while the grill gets up to max temp. I think 5 mins at max heat will work well.
I would not walk away from it for the last stage just in case...
After the sear, another 10 minute ( minimum ) should suffice.
good luck.
