Instructions
Preparing the Prime Rib
- Prepare a roasting pan with the vegetables for the base for the au jus. Place the chopped onions, carrots, celery and whole garlic cloves in the bottom of the pan, place the roasting rack over the top of the vegetables. Hold aside until the prime rib is prepared.
- If the prime rib is pre trimmed and tied, cut the strings to be able to put the rub and herbs between the ribs and meat. If the prime rib is not trimmed or split from the ribs, trim the fat to ¼" and slice the ribs apart from the meat. You can cut the ribs all the way through because you will tie them back together with butcher's twine.
- Mince the garlic cloves, shallots, rosemary and thyme leaves.
- Combine all ingredients for the rub. Mix well to combine.
- On top of the ribs place the rosemary and thyme sprigs.
- Rub a moderate amount of the Mustard Paste on the side of the meat that will contact the rosemary and thyme on the ribs. Once the mustard rub is on the meat place the meat on top of the ribs and herbs.
- Tie the prime rib back together with butcher's twine.
- Place the prime rib in the roasting pan bones down.
- Rub the remaining rub on the outside of the prime rib top and ends.
- The mustard rubbed prime rib can refrigerate overnight so there is some flavor penetration on the meat.
Roasting the Prime Rib
- A couple of hours before roasting, remove the prime rib in the roasting pan from the refrigerator to slowly bring up the temperature.
- Preheat the pellet smoker, kamado or oven to 250°. Low and slow is the key to prime rib.
- Place the roasting pan in the pellet smoker, kamado or oven once it is up to temperature.
- The typical time to roast a prime rib is 10-12 minutes per pound for rare.12-15 minutes for medium-rare. In my experience, this size prime rib on a pellet smoker takes about 3-3.5 hours for medium rare. Remember the prime rib will rest for up to an hour after removing from the smoker, kamado or oven.
- I used two wireless temperature probes to monitor the cook. Using a wireless removes the need to open the cooking source to avoid heat from escaping.
- For the Au Jus, after 2 hours of roasting add the red wine and beef stock to the bottom of the pan to make the au jus over the remaining time to cook.
- Remove the roast from the heat once the prime rib reaches the desired temperature. Remove the prime rib from the roasting pan and let it rest for 30 minutes to 1 hour to retain juices.
- While the prime rib is resting, strain the au jus left in the bottom of the roasting pan into a pot. Skim the fat from the top of the au jus and discard. Season the au jus with salt, pepper and or granulated garlic, granulated onion or worcestershire.
To Slice the Prime Rib
- Cut the strings on the prime rib and pull to remove. The crust may come apart when you remove the strings.
- Remove the meat from the ribs and herbs; place the meat on a cutting board.
- Slice the prime rib into desired thickness starting from one of the ends this will cut across the fibers of the meat.
- Serve with au jus and horseradish. Enjoy!
