Smoke Pork Shoulder Electric Smoker. Joe explains that every smoker is a little different and that the heat source will come from different areas depending on how your smoker is designed. If you have a pellet grill or an electric smoker, 225°f is a good temperature to cook your pork butt overnight.

Add the wood chips to the side tray. Close the door and set the timer for 3 hours. When the smoker reaches the set temperature, put the pork on your smoker grill with the fat side facing upward.
