How long do I cook an 19lb bone-in prime rib?
It’ll be a while… 1. Set the oven as low as it goes (most likely 200 degrees, but mine goes down to 170) 2. Rub the roast with canola oil (or veg oil) 3. Liberally salt and pepper that roast 4. Put the roast in a glass (or metal) 9×9 dish – preferably glass 5. Cook in the oven until the interior temp reaches 118 degrees (you NEED an instant thermometer – if you don’t have one, you can get one at the grocery store for ~$7). This should take at least an hour depending on the size of the roast (a multi-pound roast could take a few hours) 6. Remove the roast from the oven, and cover (loosely) with foil – think “tent.” This is the resting period, and is important 7. Crank-up the oven to 500 degrees 8. Heat the oven for 15 minutes 9. Pop the roast back-in the oven for ~15 minutes for a crust to form 10. Remove and rest for 10 minutes (or so) 11.
