    How to Choose Your Prime Rib

    If you’re an experienced user of your pellet grill, you’ll know that the cut of meat you choose is extremely important, and that’s certainly no different when it comes to prime rib. 

    Prime rib is a cut of beef taken from the upper rib area of the cow. Generally, you find them in sections of 3-7 ribs, and the more marbling the rib has, the more expensive it will be. 

    You can choose to buy a standing rib roast (with the bone in) or a rolled rib roast (which is where the bones have been removed and it has been tied into a parcel) depending on your personal preference. Generally, people prefer cooking with the bones in or tied to the base of the roll for the best flavor - however, it’s totally up to you. 

    Choose whichever “level” of quality you prefer and can afford. Prime is the best, followed by Choice, and finally Select. If you can, Prime will be best (hence the name), but if it’s out of your budget or unavailable in your grocery store, it won’t be a big deal, you’ll still get great results. 

    When choosing what size you need, it’s generally best to allocate about 0.5lbs per person, plus an extra 1-2lbs. As a guide, a 3-rib cut produces 8-10 portions, and a 7-rib produces 20-22 portions.

    How to Prepare Your Prime Rib

    You generally won’t need to do much, if any, trimming, so simply trim any fat that is over an inch thick. If you do trim, make sure you always leave a quarter of an inch of fat, don’t trim it off entirely.

    If your cut is still bones-in, take them out and tie them to the base of the roast. This will provide you with the best flavor. To remove the bones, simply cut along the top of the bone and it should slide out. Then tie the bones onto the roast with wine at the base.

    Next, marinate, inject, or rub your prime rib, as preferred. You don’t need to marinate or inject your prime rib to see good results, since it will retain a lot of moisture naturally. For rubs, you can buy readymade rubs, use a recipe, or create your own if you know what you like!

    How to Cook Your Prime Rib

    When you’re ready to cook, take your prime rib out of the fridge and allow it to come up to room temperature. This will help it cook evenly.

    Set your grill to 225F and allow it to come up to temperature, and then put your prime rib on the grill bone-side down. Cooking time will vary depending on how large your prime rib is – allow 40 minutes per pound for a medium doneness.

    When your prime rib reaches an internal temperature of 130F, it’s done! Remove it from the heat and allow it to rest for 20 minutes before serving so the flavors settle in the meat.

    What wood pellets are best for prime rib?

    You can use any wood pellets you like, though generally it’s best to avoid the most strong-flavored pellets unless they’re your favorite, as they tend to overpower the flavors of the prime rib. That means you should generally avoid Hickory Pellet and Oak Pellet. The best flavors will be lighter, so consider using Fruitwood, Apple Pellet, or Cherry Pellet.

    Should I cover or wrap my prime rib?

    In most cases, you don’t need to, unless you’re intentionally using the 3-2-1 method or it is required for your chosen recipe.

    What should I serve with prime rib?

    Popular choices for serving with prime rib are roasted or fried baby potatoes, fries, mash potato, beans, peas, roasted carrots, and anything else that takes your fancy!

    How long will my prime rib take?

    Here is a guide to help you calculate how long it will take your prime rib to cook:

    • 2-2.5lbs – 1-1.5 hours
    • 4-5lbs – 2-2.5 hours
    • 6-8lbs – 3-4.5 hours
    • 9-10.5lbs – 4.5-5.5 hours
    • 11-15lbs – 5.5-7.5 hours
    • 15-16lbs – 7.5-8 hours
    • 16-18.5lbs – 8-9.5 hours

    What internal temperature does prime rib need to be?

    Follow the guide below for the right internal temperature for your preferences:

    • Rare – 120-125F
    • Medium-rare – 130-135F
    • Medium – 140-145F
    • Medium-well – 150-155F
    • Well-done – 160F

    How do I carve prime rib?

    To carve prime rib properly, make sure you’ve got a long, well sharpened knife, then follow these steps:

    1. Place your prime rib on a cutting board after you’ve allowed it to rest for 20 minutes.
    2. Use a carving fork to hold it in place and turn the board until the rib bones are on your left side if you are right-handed, or the opposite for those who are left-handed.
    3. Make one cut to slice off the large end and then slice the meat across the grain to your preferred thickness.
