  • Our list of necessary ingredients includes seasonings such as kosher salt, black pepper, garlic powder, onion powder, dried thyme, and rosemary.
  • Preparation steps include setting up the gas grill for cooking, creating indirect heat zones, and preheating.

Gas Grill Setup and Preheating

Before you start grilling your prime rib, you need to set up your gas grill properly and preheat it. This is a crucial step to ensure even and thorough cooking.

First, remove the grates from the grill and clean them thoroughly with a brush or scraper. Then, turn on the gas and ignite the burners. Close the lid and let the grill preheat for at least 10 minutes.

During preheating, you can also add wood chips or pellets to the grill to enhance the flavor of your prime rib. Soak the wood chips in water for at least 30 minutes before using them, and wrap them in aluminum foil with several small holes poked in the top. Place the foil packet directly on the heat source to create smoke.

Next, you need to create indirect heat zones on the grill. This means that you will only have heat on one side of the grill, allowing you to cook the prime rib with indirect heat. To create an indirect heat zone, turn off one or more burners on your gas grill, and place a drip pan under the grates on the unlit side. This will catch any drippings and prevent flare-ups.

It’s important to monitor the temperature of your gas grill throughout the cooking process. Use a meat probe thermometer to keep track of the internal temperature of the grill and adjust the burners as necessary to maintain a consistent temperature. For cooking prime rib, you should aim for a grill temperature of 325-350°F.

Now that your gas grill is properly set up and preheated, you’re ready to start seasoning and preparing your prime rib!

Seasoning and Preparing the Prime Rib

When it comes to seasoning prime rib, less is often more. The natural flavors of the meat are already rich and flavorful, so simple seasonings can be used to complement and enhance the taste. A classic seasoning choice is a mix of salt, black pepper, and garlic powder. Other options include rosemary, thyme, or a blend of Italian herbs.

Before seasoning the prime rib, it’s essential to allow it to come to room temperature to ensure even cooking. You can do this by taking it out of the refrigerator at least an hour before grilling. This will also help the meat retain more moisture during cooking.

A great way to maximize the tenderness and flavor of prime rib is to dry age it. This involves leaving the meat uncovered in the fridge for several days to allow the natural enzymes to break down the tissues and intensify the flavor.

Another essential step is to properly trim and tie the prime rib before grilling. This involves removing any excess fat or silver skin to prevent the meat from curling during cooking. Additionally, you can tie the roast with kitchen twine to ensure that it cooks evenly and maintains its shape.

When grilling prime rib, a useful tip is to coat the meat with olive oil or another high-heat oil before seasoning. This helps the seasoning to adhere to the meat and creates a flavorful crust when grilled.

Finally, don’t be afraid to experiment with different seasonings and flavor combinations to find your perfect prime rib. With a basic understanding of seasoning and preparation techniques, you can create a mouth-watering grilled prime rib to impress your guests.

Grilling the Prime Rib

Now that the gas grill is preheated and the prime rib is prepared and seasoned, it’s time to start grilling. The following steps will guide you through the grilling process:

  1. Place the prime rib on the gas grill over the indirect heat zone, bone side down.
  2. Cover the grill and let it cook for about 12-15 minutes per pound for rare, 15-18 minutes per pound for medium-rare, or 18-20 minutes per pound for medium doneness.
  3. Use a meat thermometer to monitor the internal temperature of the prime rib. For rare, the thermometer should read 120-125°F; for medium-rare, it should read 130-135°F; and for medium, it should read 135-140°F.
  4. When the prime rib reaches the desired internal temperature, remove it from the grill and cover it with foil. Let it rest for at least 15-20 minutes before carving.
  5. If you want to add more sear to the prime rib, you can use the direct heat zone to char the exterior for 1-2 minutes per side before removing it from the grill.

Remember to use tongs or a spatula to handle the prime rib while grilling and flipping it. Avoid using a fork, as it can puncture the meat and release the juices, resulting in a drier and less flavorful prime rib.

Grilling on a gas grill allows for precise temperature control and even cooking, making it a preferred method for many pitmasters. By following these grilling techniques and tips, you’ll be able to achieve a perfectly seared prime rib that will impress even the most discerning BBQ enthusiasts.

Resting and Serving the Prime Rib

Once the prime rib is cooked to perfection, it’s time to let it rest. This is a crucial step as it allows the juices to redistribute throughout the meat, making it more flavorful and tender. The resting process also ensures that the meat retains its juiciness when carving.

The recommended resting time for prime rib is 15-20 minutes. You can tent it with foil to keep it warm, but make sure to leave a gap for the heat to escape, preventing the meat from overcooking.

When carving the prime rib, it’s essential to use a sharp knife and make clean cuts across the grain. This technique preserves the juiciness and texture of the meat. Slice the prime rib into portions of your desired size and thickness, and arrange it neatly on a platter.

For an extra touch of flavor, you can serve the prime rib with a selection of sauces or side dishes. Horseradish sauce, au jus, or a red wine reduction are all excellent choices. As for sides, roasted vegetables, mashed potatoes, or a green salad are classic accompaniments.

With these tips in mind, you can serve the perfect prime rib at your next BBQ. Enjoy the mouthwatering flavors and tenderness of this delicious dish!


In conclusion, cooking prime rib on a gas grill is an exceptional way to achieve a succulent and perfectly cooked meat that will tantalize your taste buds. By following the step-by-step guide and utilizing the tips and techniques provided, you can impress your guests with a delicious prime rib seared to perfection. Experiment with different seasonings and cooking times to find your favored flavor and level of doneness.

Remember to take your time in preparing the prime rib, allowing it to come to room temperature before grilling, trimming it for even cooking, and tying it properly. Pay attention to the temperature control of your gas grill, create indirect heat zones for optimal cooking, and use wood chips or pellets for added smoky flavors.

During grilling, monitor the internal temperature of the prime rib and flip or rotate it when necessary, depending on the cooking time and level of doneness you desire. Once the prime rib is cooked, allow it to rest for the recommended time before carving to ensure that the juices redistribute, resulting in a more flavorful and tender meat. Finally, serve with your preferred side dishes or sauces for an unforgettable BBQ feast!
