Notes

  • Make absolutely sure to use a roasting pan with a rack and place the rib roast towards the back of the refrigerator for the coldest, driest air.
  • For best results, use a bone-in prime rib. The bones help retain moisture and flavor in the meat, which is especially important with dry aged rib roast!
  • You don't need to worry about tying the prime rib as it ages, but tie the prime roast before cooking it. Dry aging makes the meat so tender and soft, it needs to be helpd together or it can fall apart from the weight of the bones!
  • If you don't want the fridge to smell like beef, place a box of baking soda next to the rib roast in the fridge. This will keep the smell down.
  • This process is easy, but it takes a long time and a lot of fridge space. Plan accordingly to set aside enough space without crowding too many things around the beef!
  • Actual nutrition values will vary based on the recipe used for cooking the prime rib and the weight of the roast you use.
