Prime rib is great. Prime rib with a garlic-herb crust roasted on its own ribs is even better! This method produces a tender, succulent prime rib roast and the crust adds an incredible flavor that everyone at the dinner table will enjoy.

It's important to note that prime rib should never be cooked more than medium-rare. Doing so toughens the meat. If some of your guests like it a bit more done, use a restaurant trick and simply pour the piping hot pan juices over the sliced meat. This will cook it a bit more and they'll love it.

What You'll Need

How to Make It

Quick Tip: For this cooking method to work, it is essential that your prime rib roast reaches room temperature before placing it in the oven.

  1. Position the oven rack on the lowest level in the oven. Preheat oven to 450 F.
  2. Carefully remove prime rib roast from the bones so that the bones remain attached to each other (or have your butcher do it for you). Place the bones in the bottom of a large heavy roaster pan. The ribs will serve as the rack for the roast.
  1. Sprinkle both ribs and roast generously with the salt and pepper.
  2. Place garlic, onion, horseradish, oregano, flour, and mayonnaise in a food processor and pulse until it forms a smooth paste.
  3. Press the garlic paste onto all sides of the roast and place fat-side up on the rib rack in the pan.
  4. Place the pan in your pre-heated oven and bake for 20 minutes.
  5. Reduce oven heat to 275 F. Bake an additional 1 1/2 hours or until an instant-read thermometer inserted in the center of the roast indicates a temperature of 110 F for medium-rare. (Roast will continue to cook after you remove it from the oven.) Check at 10-minute intervals until it reaches the desired temperature.
  6. Move prime rib roast and ribs to a platter and keep warm. Let rest at least 15 minutes before carving.
  7. Meanwhile, pour drippings from the pan into a gravy separator or glass measuring cup. Siphon off grease and reserve juices.
  8. Place the roasting pan over medium-high heat and add red wine. Deglaze the pan by stirring to scrape up all the browned bits from the bottom of the pan.
  9. Boil until juices are reduced by half -- about 5 to 8 minutes.
  10. Add beef broth, reserved beef juices, and any juice that has collected in the platter. Cook, stirring often, until reduced again by half.
  11. Slice the prime rib roast and the separate ribs. Serve with the reduced pan sauce and Creamed Horseradish Dill Sauce.

Tip: Use a blender or food processor to grate the horseradish. It's finer, faster, and easier than a box grater. Just be careful of the fumes as they will burn your eyes and nose.

Open the window and keep the food processor at arm's length when removing the lid.
