Ingredients

For the Prime Rib Roast

  • 1, 4-7 pound prime rib roast boneless or with the ribs cut away and tied back
  • ¼ cup melted butter, ghee, or bacon fat
  • 1 tablespoon fresh thyme
  • 1 tablespoon lemon zest (from 1 lemon)
  • 2 teaspoons sea salt
  • 1 teaspoon ground black pepper

For the Creamy Horseradish Sauce (optional)

  • ¾ cup coconut cream (the solid portion from 2 cans of full-fat coconut milk)
  • 4 tablespoons prepared horseradish
  • 2 tablespoons lemon juice
  • ½ teaspoon sea salt

Instructions

  • Let the rib roast rest on the counter at room temperature for 1-3 hours before roasting.
  • Preheat the oven to 450°F.
  • Whisk the melted butter, salt, pepper, thyme and lemon zest together. Massage it thoroughly over the entire rib roast.
  • Lay the roast on the center of a rack in a roasting pan, and roast at 450°F for 20 minutes.
  • Reduce the temperature to 325°F and roast for 15 minutes for each pound of uncooked roast (so, a 6-pound roast will need 1½ hours). Note: this timing will end in a medium-rare finish; reduce the equation to 14 minutes for each pound for a rare finish.
  • If you're making the optional creamy horseradish sauce, whisk all ingredients together in a bowl and refrigerate for at least one hour to thicken.
  • Remove the roast from the oven and let it rest, covered loosely with foil, on the counter for 30 minutes before carving. Then carve, serve, and enjoy!
