Instructions
 

  • Remove roast from the fridge and unwrap it on a cutting board.
  • Using a sharp boning knife, carefully cut the bones (in one piece) from the roast, being sure not to remove too much meat from the bones.
  • Season the roast all over generously with Garlic Junkie seasoning.
  • Between the roast and the bones, sandwich a big handful of fresh herbs and some extra Garlic Junkie seasoning.
  • Using kitchen twine, tie the bones back on to the roast, securing tightly.
  • Transfer the roast to a wire rack over a cookie sheet and place it in the fridge for at least one hour– and up to over night.
  • Preheat the Traeger grill to 225* with the super smoke feature.
  • Place the prepared roast in the grill, with the Meater thermometer inserted, and close the lid.
  • Set the desired temperature on the Meater app to 110*.
  • Allow the roast to cook until it reaches 110*.
  • Bump up the temperature of the grill to 400*, and leave the roast in the grill.
  • Adjust the desired temperature on the Meater to 120*.
  • Allow it to get very hot and sear the roast all over until the internal temperature eaches 120*.
  • Adjust the Meater temperature one more time to 130*.
  • Remove the meat from the grill, tent with foil and allow to rest until the desired temperature reaches 130*.
  • Slice with a sharp knife and serve with caramelized onion horseradish sauce.
  • While the roast is cooking, make the sauce.
  • Thinly slice the onion and cook in a saucepan with lots of butter until very soft, golden and caramelized.
  • In a bowl, combine the mayo, sour cream, horseradish sauce, cooked onions and shredded cheese.
  • Mix until well combined and season to taste.
