Cooking Directions:
Preparation:
- Remove from the cryo-vac package and put onto a large cookie sheet pan, allow to drain any juices, and warm up at room temperature for 20 minutes.
- Next, liberally rub on all sides with your choice of seasoning. Use our Prime Rib Rub-a-Dub or Standard Rub-A-Dub or a 50/50 blend of both.
- We do not recommend SALT CRUSTED for our cooking process
- Allow the rub to sit on the Prime Rib for another 20 minutes, then wrap it in plastic wrap and place it on a cookie sheet pan and into the fridge. I suggest leaving wrapped for 12-18 hours
WHEN READY TO COOK THE PRIME RIB
- Pre Heat your Big Green Egg (or grill) to 200 degrees and load with your preferred smoking wood chunks (Layer in the wood chunks to create an even sustained smoke flavor)
- Add the ConvEGGtor legs up and then place the grill grate on top of convEGGtor
- Adjust Temp to 350 Degrees
- Place the Prime Rib into a roasting pan, on a roasting rack to catch the drippings. Ribs or Rib Side Down. Fat Side Up.
- Add any additional seasoning to the top of the prime rib if desired
- Add any bacon fat or butter to the top of the prime rib if desired
- Load your iGrill or Meater probe if desired (or other Bluetooth or Wi-Fi thermometer)
- DO NOT COVER THE PRIME RIB DURING THE COOKING PROCESS
- Close the lid and sear at 350 degrees for 20 minutes, then turn the Big Green Egg down to 325 and cook until desired doneness is reached (see chart below for approx. cooking times and doneness levels)
- Remove from the Big Green Egg with time to allow for resting and carryover.
- CHEF TIP: I remove my prime rib about 10-12 degrees before my desired temp, this allows carry-over and resting
- Slice and enjoy with our Au Jus or Horsey Sauce

Understanding Prime Rib
First, let’s start off with the definition of Prime Rib. What is Prime Rib? Is it Prime?
- A standing rib roast, also known as prime rib, is a cut of beef from the primal rib, one of the nine primal cuts of beef. While the entire rib section comprises ribs six through 12, a standing rib roast may contain anywhere from two to seven
PRIME in the term PRIME RIB means it’s one of the 9 PRIME Cuts of meat. (Chuck, Rib, Short Loin, Sirloin, Round, Brisket, Shank, Plate, and Flank) Depending on the budget you have for this holiday or celebration treat there is a quality level to meet your needs. We find that by placing our orders before the holiday season starts, we are able to get better pricing and then pick up as we need. Check with your local butcher, grocery store, grocery club or meat counter and see if this is something they can offer. Prices do increase during high-demand seasons and holidays. Here are the TOP 5 Quality Grades and some info for you to read:
- S. Prime – Highest in quality and Moderately Abundant Marbling, limited supply.
- S. Choice – Certified Angus Beef – This grade represents the upper 2/3 of the Choice range. Higher quality and Moderate Marbling
- S. Choice – High quality and Modest Marbling
- S. Select – Medium quality and Slight Marbling
- S. Standard – Lower quality and Trace Marbling
Selecting the Perfect Prime Rib
I am having 6 people over, how much should I buy? Do I need to buy it with the rib bones on?
- A good rule of thumb is to plan on 1 bone per 2 people. That can equate to about 10 oz of cooked prime rib per person. Keep in mind there will be a small amount of shrink while cooking, so buy a tiny bit extra to ensure you have some leftovers for those shaved prime rib sandwiches the next day.
- Bone or No Bone??? While the bones do add a great flavor, it’s not necessary to cook a bone-in rib roast. If cooking a boneless roast please follow the same methods as above and reduce total cooking time by 20-30 minutes depending on the cooking tool used.
- When choosing a size, we don’t recommend buying anything under a 2-bone portion, as this is more of a thick steak-style cut and will be difficult to roast and keep from drying out.
