I am cooking a 10 lb pork roast in a crock pot for pulled pork. How long should I cook it?
Hmm… for pulled pork, I usually do 8 hours on low for a 3-4 lb roast.
Since you’re pulling it anyway, I’d consider chopping it in half -put both halves in, but it’ll make it more likely the centre cooks properly. I’d also consider browning it in the oven first -just stick it under the broiler for a few minutes til the outside browns nicely. (Also, if there’s a visible fat cap, trim that before it goes in the slow cooker, or the fat rendering will make it taste funny.)
Lastly, in a crock pot don’t add much liquid -just what you need to flavour. It’ll release so much liquid as it cooks, and it doesn’t evaporate. If you want a thick sauce, mix that with the pork at the end, don’t cook it with the pork.
This person thinks 14 hours for a 7-lb roast (http://www.theclothesmakethegirl.com/2012/10/16/slow-cooker-italian-pork-roast/), but it also depends on how thick the cut is and how new your crock pot is. Newer crock pots cook faster.
So, I would say if it’s a fairly new crock pot, and you’ve cut the roast in half so more is exposed, and you’ve browned it in your oven first, 12-14 hours on low. You could also start it on high for 4-5 hours and on low for 4-5 hours if you need it to be faster.
