In this blog, we will discuss a mouth-watering recipe to cook prime rib on a gas grill.

Preparing the Prime Rib to Cook on a Gas Grill

Here are some of the steps you may have to follow while preparing the prime rib.

The trim and peel steps are maybe optional as they depend on how fancy you may want to get. But the rub and rest technique is highly recommended before grilling your prime rib.

Separate the Silver Skin 

If you have cooked ribs before, you may know how necessary it is to remove the silverskin from the backside of the bones. Although it is a rigid membrane that may ruin your good bite. As the rib roast has this membrane too.

However, the removal of this silverskin is completely optional. When you are eating pork ribs, you may pick them up and bite into the flesh. And that silverskin of pork may create a tough bite and ruin the whole taste.

Along with a prime rib, it does not matter to you with a fork and knife. Generally, you may not bite meat right down near the bone. You just want to remove it so the rub has more contact with the flesh in between the bones.

For doing this, you have to flip the roast upside down and then seize the membrane with the help of a paper towel. And then peel it off and put it in the trash.

Frenching the Bones 

Most modern restaurants drag the meat away from each bone and leave them connected to the rib roast. Although it’s all your choice to do the frenching of bones, it may create a very pretty presentation. As the bones are clean and stick out from the big hunk (stuff) of beautiful meat.

But in case you or your family member likes to chew the leftover bones of prime ribs, then you do not have any need to french them.

Secret Trim 

It is just a simple little bit of special trim that you can do to add some flavor to your prime rib. For this, run the knife between the bones and meat and continuously slice down unless you may reach the bottom of the flesh. But ensure that you do not separate the two.

After that when you are adding your rub, you may also add rub-down via that trimmed secret area. You will see a nice little secret once it is cooked. When you are following this technique you may need some butcher’s twine to secure the bones back to the roast, particularly when you are cooking it in a rotisserie.

Now the time comes to slice your grilled prime rib, and here you have to quickly remove the twine and bones so they are not in your way. Next, slice the flesh into slices thin or thick up to as what your supper prefers.

Rub and Rest 

Unlike turkey legs that may get a wet brine in the fridge, but the prime rib may get a dry brine. It is also left out on the counter and yes it is very safe as long as you do not exceed 4 hours.

When you leave it on the counter, it may slowly come to the normal temperature before it hits the grill. When you put the rib on the grill at the fridge temperature of 40 degrees F, it is not going to cook evenly. And the center of flesh may take longer to warm while outside will overcook.

It is better to leave it on the counter for 2 to 3 hours. While it’s placed around waiting you can make a season of robust herbs mixed with Brisket Rub, olive oil, garlic, and allspice.

How to Cook Prime Rib on a Gas Grill?

The whole cooking method may include 3 main stages. And these are:

  • Slow cook
  • Crust creation
  • Rest

Step #1: Slow Cook 

For a delicious prime rib, you have to keep the warm-up slow going by grilling it at very low, indirect heat. However, 250 degrees F is the recommended one. Make sure to place prime rib on the grill fat side up. In this way, any fat juices will give back into the middle of the roasted rib.

You do not want to cook it at this temperature all the way. Regardless of this, set an internal meat temperature of at least 110 F degrees. Usually, a digital thermometer is recommended for this such as ThermoWorks Smoke. As it may alert you when your meat reaches 110 F degrees. A 6-pound rib roast may take about 2 hours for cooking.

Step #2:  Crust Creation 

One of the best parts of the rib roast is the herbaceous crust. For creating this, you have to crank the grill heat up to 400 F degrees. After that just keep on grilling over the indirect flame until the internal temperature reaches 135 degrees F. Do not forget to alter your digital meter so that it will alert you when it’s ready.

Step #3: The Rest

As your roast reaches 135 degrees F, take it off the grill and let it rest for half an hour. This resting step is one of the most important ones. In case you cut the prime rib right away, all of the magical juices may be lost on your cutting board. Resting is essential so that the juices will reabsorb back into the meat, which means every bite will be juicy.
