Ingredients

  • 5 pounds prime rib roast
  • 1/2 cup unsalted butter, softened
  • 2 tablespoons Kosher salt
  • 2 tablespoons coarse ground black pepper

How To Make super easy always perfect prime rib roast

  • Step 1
    Remove roast from the refrigerator at least 3 hours (up to 4) before ready to roast. It must be room temperature in order to cook evenly.
  • Step 2
    Preheat the oven to 500 degrees F. Meanwhile, whisk together the remaining ingredients until they are smooth. Rub the roast all over until it is evenly coated on all sides.
  • Step 3
    Place the meat in a roasting pan, rib side down. Sprinkle the top generously with more Kosher salt or sea salt.
  • Step 4
    Roast for 5 minutes per pound. So... a 5-pound roast for 30 minutes, a 6-pound roast for 35 minutes, etc.
  • Step 5
    Turn off the oven. DO NOT OPEN THE OVEN DOOR! Let it sit in the oven for 2 hours. REPEAT - DO NOT OPEN THE OVEN DOOR DURING THIS TIME!
  • Step 6
    Remove the roast from the oven. Tent with foil and let rest for 10 minutes. The internal temperature of the roast should be around 130 degrees for medium rare.
