Prime Rib on the Grill

Ah, prime rib. Also known as standing rib roast, it’s one of those delectable cuts of meat taken from the primal (upper) rib portion of the cow. It’s known for it’s velvety tenderness and oodles of flavor from a plethora of fat marbling. Prime rib has a special place it my heart. Growing up, it was a Christmas Eve tradition to have prime rib for dinner.

Prime rib looks and tastes fancy, and those Christmas Eves always made me feel like royalty. For over 30 years, I’ve been enjoying prime rib during the holiday season, and I encourage you to make it a part of your holiday traditions as well.

Let’s dive into more specifics for grilling a prime rib on the rotisserie, shall we? When you head to the store or butcher to purchase your roast, make sure to buy it bone-in (the meat itself will likely be called “bone-in rib roast”). Also, ask your butcher to tie the roast tightly prior to taking it home. This is save you a step, and ensure the roast is a consistent size to help it evenly cook on the grill.

For today’s recipe, I’m cooking a 6-pound prime rib roast on my Weber Genesis II gas grill on a rotisserie. Home Depot is making it easy to grill this holiday season with free delivery on all grills purchased online and free assembly on all grills purchased in-store.

When purchasing prime rib, aim for around 6 ounces to 1 pound per person. Feel free to go as big as you want with your prime rib roast. Five to 6 pounds feeds my family perfectly. If you have a large crowd to feed, feel free to grab a 10-pound roast (this should serve 8-12 adults). Keep in mind that if you adjust the size of roast you purchase, the cook time will change depending on the size of the roast.

To prep the roast, make 16 slits in the meat and stuff each opening with 1 garlic clove. Season the prime rib with my Signature Beef Seasoning, or an equal mixture of kosher salt and black pepper. Cover the seasoned roast with plastic wrap or aluminum foil and allow the meat to rest for 2 hours prior to cooking.

Once you have your prime rib seasoned and allowed to rest for 2 hours, it’s time to stick it in the heat! Follow these simple instructions on how to cook prime rib on the grill so it comes off juicy, tender, and oh-so good.

  1. Preheat your grill. For this recipe, I used my Weber gas grill with the rotisserie attachment. Preheat your grill to 450 degrees F for indirect heat. I turned burners 1 and 4 on high with the middle two burners turned off.
  2. Cook the prime rib. For a 4-6 pound prime rib roast, plan on around 2 hours of cook time. A 6-10 pound roast will likely require 3 to 3 1/2 hours in the rotisserie. You’ll know when it’s time to remove the prime rib from the grill when the internal temperature measured by a meat thermometer reaches 125-128 degrees F (if cooking to medium rare). Keep in mind that carryover cooking does a LOT on a high temperature cook like this, meaning the temperature of the meat will typically increase 8-10 degrees after it is removed from the grill.
  3. Rest and serve. Next, remove the roast from the grill (keeping it on the rotisserie rod) and allow the prime rib to rest for 30 minutes before serving. During this time, carryover cooking will increase the internal temperature of the roast to 135 degrees F.

Prime rib is best enjoyed at medium rare doneness, but rare and medium are also acceptable. (Though, trust me when I say medium rare is the magic temperature). Whenever prime rib is cooked above medium, it begins to toughen and lose that characteristic prime rib texture.
