Once you've gotten the necessary materials together, you can finally begin on the recipe.

Step 1: Seasoning the Prime Rib Roast

First, make several half inch deep holes in your meat across all sides of the roast with a sharp knife, spaced about two inches apart. Fill the holes with slivered pieces of garlic and rosemary leaves alternating between the two (this will likely require about 7 cloves of garlic and 3 sprigs of rosemary depending on how thinly you cut the garlic and how many leaves are on a sprig).

Once the holes have been filled, mix together two tablespoons each of black pepper, kosher salt, paprika, and dried rosemary with a tablespoon of vegetable oil, rubbing or brushing it onto the meat on all sides. Also, check out our Herb and Spice Guide to learn more about seasonings!

Once seasoned, allow the meat to rest at room temperature for half an hour. This lets the meat warm up slightly before it hits the heat, ensuring a more even cook and a juicier end product.

Step 2: Lighting the Grill

While your roast warms up, now is a good time to light the grill. The properly cook prime rib using this method, you need to set up your grill for indirect cooking at a grill temperature of about 375 degrees Fahrenheit.

For a charcoal grill, this would mean placing coals only on one side of the grill or using a heat diffuser, while keeping one area of a propane grill turned off. Additionally, add a grill safe baking pan underneath the space you plan to put the prime rib, as this will let you catch the drippings you'll use for making gravy later on.

Step 3: Grilling the Prime Rib Roast

Once the grill and the meat have come up to temperature, you can begin cooking. Place your prime rib roast onto the grate in the cold spot you make earlier for indirect grilling. You can expect the roast to cook for around 12 minutes per pound of meat, meaning close to 3 and a half hours for a roast this size.

Remember to periodically add a little bit of water to the baking pan catching the drippings to prevent them from burning. You'll know the meat has been fully cooked when a thermometer stuck into the thickest part of the meat reads an internal temperature of the meat of 115 degrees Fahrenheit.

Step 4: Resting the Prime Rib Roast

When the meat has reached the designated temperature, remove it from the grill and place it onto a cutting board or other flat surface. Tent loosely with aluminum foil and let it rest for at least 20 minutes if not an hour.

During this resting period, the meat fibers will relax and reabsorb some of their lost juices, leading to a more tender and flavorful meat. Additionally, this extra time allows the residual heat inside the roast to distribute evenly, raising the temperature by about 5 degrees and ending the cooking process.

Step 5: Making the Gravy

As your meat rests, now is the perfect time to make some delicious gravy to go with it. Place the pan full of drippings onto the stove and heat it over medium heat. Add in a few tablespoons of flower, stirring it into the fat until it's completely coated.

Cook the flower for about two minutes before adding in a cup of beef or chicken stock, whisking the mixture vigorously and scrapping the bottom of the pan to loosen any browned bits stuck to the bottom.

Continue cooking the gravy until it reaches your desired thickness, adding salt and pepper to taste. You could also toss in a few fresh herbs to help make it extra flavorful. Once it's done, strain it through a fine mesh sieve into a container.

Step 6: Serving the Prime Rib Roast

Once both your meat and gravy are ready, it's time to eat. The great thing about prime rib is that it's already pre-portioned for you, taking out any of the guesswork on how much everyone gets.

Just cut the meat in between each bone and plate it up with some sides. You can choose to either pour the gravy over the meat or pour it into individual ramekins for dipping or self-serving purposes. No matter how you choose to eat your prime rib, though, it's sure to taste great.
