Expert Tips

  • For an extra pretty presentation, top sliced roast with more fresh chives or thyme leaves.
  • You can make the Creamy Horseradish Sauce served alongside this dish up to two days in advance. Store covered in the refrigerator and give it a stir before serving.
  • Prime rib may be called standing rib roast, beef rib roast or prime rib roast, but all of these names refer to the same delicious cut of meat. This cut may be bought bone-in or boneless. This recipe calls for using a bone-in recipe, which adds flavor and helps keep the meat moist.
  • It can be a little tricky to carve a bone-in prime rib roast, but if you go slowly, use a sharp knife and remember these tips, you’ll be fine. First, once the meat is cool enough to handle, place on cutting board and carefully carve the bone away from the meat. Then, once the bone has been removed, turn the roast bone side down and cut slices evenly and toward the bone side of the roast.
  • This cut of meat is typically served medium rare, which means the inside will still be quite pink. Don’t worry, as long as you follow the temperature instructions included in this recipe, your meat will be food safe. Keeping meat on the rare side brings out its rich, buttery flavor.
