Tips

  • Modern pork is safe and juicy at 145°F, a little pink is fine.
  • For pulled pork, cook a shoulder/butt low & slow (about 90 min/lb at 250°F) to ~203°F.
  • Rest 3 minutes (longer for a big roast) before slicing.
These times are estimates that vary with your oven, the starting temperature of the meat and other factors. Always verify doneness with a food thermometer before serving.
