Equipment

Ingredients

  • 6-8 lbs pork prime rib roast
  • 2 tablespoon kosher salt
  • 3 tablespoon grainy mustard
  • 1 ½ tablespoon fresh thyme

Instructions

  • If desired, season pork with salt and allow it to sit in the fridge for at least 3 hours.
  • About 45 minutes before cooking, remove the roast from the fridge. Preheat oven (with the rack in the middle) to 275F. Placing the roast on a roasting pan with an insert, spread evenly with grainy mustard and sprinkle thyme.
  • Cook until 130F when inserted into the center of the roast, remove from the oven, tent and rest until about 135F.
  • Preheat the oven to 450F, then cook for another 8-12 minutes until the outside is browned.
  • Rest for another 10 minutes until the temperature rises to about 140-142F.
  • Slice between the bones and serve.

Notes

  • Let it Rest Twice: Resting allows juices to redistribute for tender slices.
  • Roast Fat Side Up: The fat cap helps baste the meat naturally as it cooks.
  • Don’t Skip the High Heat: That final step creates the crust for added texture.
  • Use a Meat Thermometer: Do not just rely on cooking time, since the size of your roast and ovens can vary.
  • Refrigerator: Store sliced pork, tightly wrapped, in an airtight container for up to 3-4 days.
  • Freezer: Wrap tightly in plastic wrap and aluminum foil and place in a freezer-safe bag for up to 2 months.
  • Reheating: Warm gently in a 300F oven, with a splash of broth or water, covered with foil to avoid drying out.
