  • 5 pounds beef prime rib
  • 1-2 tablespoons salt
  • 2 teaspoons pepper
  • 1 teaspoons fresh rosemary chopped
  • 1 teaspoon fresh thyme chopped
  • 1 teaspoon sage chopped
  • 10 garlic cloves minced
  • Olive oil spray


  • One hour before roasting your prime rib, remove it from the fridge and season it on all sides with salt and cover it loosely with plastic wrap. (This will help the prime rib cook more evenly)
  • Preheat the oven to 500°.
  • In a small bowl, combine the pepper, rosemary, thyme, sage, and garlic.
  • Pat the roast with paper towels to dry it. Then sprinkle the seasoning all over it, rubbing it all over. And spray lightly with olive oil.
  • Place roast in a roasting pan, with the bones side down. Or place a boneless roast on a rack inside the pan.
  • Bake prime rib for 15 minutes, then reduce the oven temperature to 325° and continue baking until desired doneness. (see below)
  • Remove the prime rib from the oven and tent it with foil. Allow it to rest for 30 minutes before carving.
  • Carve the roast against the grain at about 1/2 inch thickness.
