Roast your pork shoulder in the oven at 350 degrees F for 30 to 35 minutes per pound for a nice slicing roast. At this temperature, a 6-pound pork shoulder will require 3 to 3 1/2 hours to roast. Check for doneness by placing a meat thermometer into the roast at the thickest point. Be careful not to touch the bone.
Pork shoulder normally cooks around 1.5-2 hours per pound of meat and my shoulders normally cook for 15-19 hours then rest in a cooler for 2 hours before serving. Pork shoulder yields delicious pulled pork sandwiches and the left overs are perfect for bbq pizza, tacos, and can be frozen for later use.
