Choosing the Right Prime Rib

The first step to grilling the perfect prime rib on a gas grill is choosing the right cut of meat. When selecting your prime rib, look for a well-marbled piece with even thickness throughout.

The marbling will add flavor and tenderness to your meat, while an even thickness ensures that it cooks evenly on the grill.

Another important factor to consider when choosing your prime rib is its size. A general rule of thumb is one pound per person, but you may want to adjust this based on how much other food you plan on serving alongside it.

Lastly, make sure that you purchase a bone-in or boneless roast depending upon personal preference and cooking style. Bone-in roasts tend to have more flavor due to their proximity with bones during cooking while boneless roasts are easier for carving after they’re cooked.

Preparing the Prime Rib

First and foremost, make sure that your prime rib is at room temperature before cooking. This will help ensure even cooking throughout the meat.

Next, trim any excess fat or silver skin from the outside of the roast using a sharp knife. Leaving too much fat on can cause flare-ups on the grill and result in unevenly cooked meat.

Once trimmed, pat dry with paper towels to remove any moisture from the surface of the roast. This will help create a nice crust when searing on high heat later in preparation for slow-cooking over indirect heat.

Tie up your prime rib with butcher’s twine if necessary to ensure even cooking and presentation once it’s done grilling.

Seasoning the Prime Rib

Seasoning is a crucial step in bringing out the natural flavors of your meat and enhancing its taste. There are many ways to season a prime rib, but one popular method is using a dry rub.

To make your own dry rub, mix together salt, black pepper, garlic powder and any other herbs or spices that you prefer. You can also try our coffee rub recipe for an extra kick of flavor! Rub the seasoning mixture all over the surface of your prime rib until it’s evenly coated.

If you have time before grilling (ideally 24 hours), wrap up seasoned meat tightly with plastic wrap and refrigerate overnight so that flavors penetrate deeper into beef fibers.

Remember not to go too heavy on seasoning as this could overpower the natural flavor of your meat. A good rule of thumb is about 1 tablespoon per pound or less depending on personal preference.

Coffee Rub Recipe

A coffee rub is an excellent choice for adding depth and complexity to your meat’s flavor profile. Here’s how you can make your own coffee rub at home:


  • 1/4 cup finely ground coffee
  • 2 tablespoons brown sugar
  • 1 tablespoon smoked paprika
  • 1 tablespoon kosher salt
  • 2 teaspoons garlic powder
  • 2 teaspoons onion powder
  • Optional: cayenne pepper or chili flakes for heat


  1. In a small bowl, mix together all ingredients until well combined.
  2. Generously apply the rub onto all sides of your prime rib before grilling.

Gas Grill Setup

First, make sure that the grill is clean and free of any debris from previous use. Then, turn on the gas supply and ignite all burners to preheat the grill.

Next, adjust the heat settings according to your desired cooking temperature. For a medium-rare prime rib (which is recommended), aim for a temperature of around 325°F (163°C).

This will ensure that the meat cooks evenly without burning or drying out.

To create an even cooking surface for your prime rib, it’s also important to create a two-zone cooking area on your gas grill by turning off one burner while leaving another burner on high heat. This will allow you to sear both sides of the meat before moving it over to indirect heat for slower roasting.

Preheating the Grill

Preheating ensures that the grill is at the right temperature for cooking and helps prevent sticking. To preheat your gas grill, turn all burners on high and close the lid.

Allow the grill to heat up for 10-15 minutes until it reaches a temperature of around 450°F.

Preheating also helps eliminate any residual flavors or odors from previous grilling sessions that may affect the taste of your prime rib. It’s essential to ensure that there are no leftover food particles or debris on the grate before placing your meat on it.

Once you’ve finished preheating, use a wire brush or scraper tool to clean off any remaining debris from previous cookouts thoroughly. This step will help prevent flare-ups during cooking and keep unwanted flavors out of your dish.

Creating a Two-Zone Cooking Area

This means that you’ll have one side of the grill with direct heat and the other side without any flames. The direct heat zone is where you’ll sear your prime rib, while the indirect heat zone is where it will finish cooking.

To create this setup, turn on all burners to high and close the lid for about 10-15 minutes until your grill reaches around 450°F. Then turn off one or more burners (depending on how large your roast is) and place an aluminum drip pan under where there are no flames.

This method allows for even cooking throughout without burning or overcooking any part of your meat. It also helps prevent flare-ups from dripping fat which can cause uneven charring or burnt spots.

Monitoring Grill Temperature

This will ensure that your meat cooks evenly and doesn’t burn or dry out. A digital thermometer with a probe is an essential tool for monitoring the internal temperature of your prime rib, but you also need to keep an eye on the external temperature of your grill.

Before you start grilling, make sure that all burners are turned off and allow time for any residual heat from previous use to dissipate. Then preheat one side of the grill on high heat while leaving the other side unlit (creating two zones).

Once preheated, adjust both sides so they maintain their respective temperatures: 450°F-500°F (230°C-260°C) for direct heat zone and 250°F-300°F (120°C-150°C) for indirect heat zone.

Throughout cooking time check every few minutes if necessary by using either built-in thermometer or instant-read thermometer inserted through lid vent hole into center area above food grate level.

Avoiding Flare-Ups

To avoid flare-ups, make sure to trim excess fat from the meat before cooking. Fat dripping onto hot coals or burners is one of the main causes of flare-ups.

Another way to prevent flare-ups is by creating a two-zone cooking area on your gas grill. This means having one side of the grill with direct heat (burners turned on) and another side with indirect heat (burners turned off).

Place your prime rib over the indirect heat zone and close the lid to allow for even cooking without exposing it directly to flames.

If you do experience a flare-up while grilling, don’t panic! Use tongs or a spatula to move any burning pieces away from your meat until they die down. You can also keep a spray bottle filled with water nearby in case you need it.

Thermometer Placement

This ensures that your meat is cooked to perfection and safe for consumption. To do this, you’ll need a reliable meat thermometer.

When it comes to thermometer placement, there are two key areas you should focus on: the thickest part of the roast and avoiding contact with bone or fat. Inserting your thermometer into these areas will give you an accurate reading without affecting the overall texture or flavor of your prime rib.

It’s also important to note that different thermometers have varying levels of accuracy, so be sure to check yours against other thermometers or use a digital probe for more precise readings.

Grilling Time for Prime Rib

As a general rule of thumb, plan for about 15-20 minutes per pound of meat. However, this can vary depending on factors such as grill temperature and weather conditions.

To ensure that your prime rib cooks evenly throughout, it’s important to flip it occasionally during the grilling process. Use tongs or spatulas instead of piercing the meat with forks which can cause juices to escape resulting in dryness.

It’s also essential that you use an instant-read thermometer inserted into thickest part (not touching bone) towards end of cooking time so as not overcook or undercook your roast. For medium-rare doneness aim for an internal temperature between 130°F -135°F; medium: 140°F-145°F; medium-well:150° F -155° F; well done:160 °F+.

Applying Additional Seasoning

This step is optional but highly recommended if you want to take your dish to the next level. You can use any seasoning of your choice, such as garlic powder, onion powder or even a coffee rub recipe.

If using a dry rub, sprinkle it generously over the entire surface of the meat and pat it down gently with your hands so that it adheres well. If using a wet marinade or sauce, brush it onto both sides of the prime rib with a basting brush.

Be careful not to add too much additional seasoning as this can overpower the natural flavors of the meat and ruin its tenderness. A little goes a long way when applying seasonings on prime rib.

Flipping the Prime Rib

This step is crucial in ensuring that both sides are cooked evenly and have a beautiful sear. Use tongs or a spatula to carefully turn over the meat, being careful not to pierce or tear it.

When flipping your prime rib on a gas grill, timing is everything. You want to make sure that you’re only flipping once during cooking as this will help retain moisture and prevent any unnecessary drying out of the meat.

After flipping, take care not to move or disturb the prime rib too much as this can cause juices inside it to escape prematurely leading dryness in some parts of your roast beef.

Internal Temperature Guide

The ideal temperature for a medium-rare prime rib is 130°F (54°C), while a medium-well done roast should reach an internal temperature of 145°F (63°C). Keep in mind that the meat will continue to cook as it rests, so be sure to remove it from the grill when its internal temperature is about five degrees lower than your desired doneness.

Use a reliable meat thermometer and insert it into the thickest part of the roast without touching any bones or fat. This will give you an accurate reading of how well-done your prime rib has become during grilling.

By following this simple guide, you’ll be able to achieve perfectly cooked and juicy prime ribs every time!

Resting the Prime Rib

Resting allows the juices to redistribute throughout the meat, resulting in a more tender and flavorful final product.

To rest your prime rib, simply transfer it to a cutting board or platter and cover loosely with foil. Letting your roast sit for at least 15-20 minutes will give you optimal results.

While waiting for your prime rib to rest, resist any temptation to cut into it right away! Cutting too soon can cause all those delicious juices that have accumulated inside of the meat during cooking process spill out onto your cutting board instead of staying inside where they belong.

Instead, use this time wisely by preparing any sides or sauces you plan on serving alongside your main dish.

Carving the Prime Rib

Carving a prime rib can be intimidating, but with the right technique, you’ll have perfectly sliced pieces in no time.

Start by removing any twine or skewers that were used during cooking. Then, using a sharp carving knife or electric knife if you have one available, slice against the grain of the meat into desired thicknesses.

It’s important to cut against the grain as this will result in more tender slices.

If serving bone-in prime rib roast (which is highly recommended), use kitchen shears to remove each bone before slicing between them. This will make it easier for guests to enjoy their preferred level of doneness without having to navigate around bones.

Arrange your beautifully carved slices on a platter and serve immediately with your favorite sides such as roasted vegetables or mashed potatoes. Don’t forget about sauces! Horseradish cream sauce is always an excellent choice when serving prime rib on special occasions like Christmas dinner or Easter brunch.

Serving Suggestions

One classic way is to slice the prime rib into thick pieces and arrange them on a platter with some fresh herbs for garnish. You can also serve it alongside roasted vegetables or mashed potatoes for a complete meal.

Another popular option is serving the prime rib as part of a sandwich or wrap. Simply slice the meat thinly and layer it onto bread or tortillas with your favorite toppings such as lettuce, tomato, cheese, horseradish sauce, or caramelized onions.

If you have any leftovers (which may be unlikely!), they make great additions to salads or sandwiches throughout the week. Just be sure to store them properly in an airtight container in the fridge.

Sauces for Prime Rib

Here are some classic and creative sauces that pair well with prime rib:

1. Horseradish Sauce: A classic pairing with prime rib, horseradish sauce adds a tangy kick to the rich meat.

2. Red Wine Sauce: Made by deglazing the pan drippings from cooking your prime rib with red wine and beef broth, this savory sauce is perfect for those who prefer their meat on the savory side.

3. Chimichurri Sauce: This Argentinean herb-based condiment made of parsley, garlic, olive oil and vinegar pairs beautifully with grilled meats like steak or in this case -prime ribs!

4. Mushroom Gravy: A creamy mushroom gravy made from sautéed mushrooms in butter mixed into beef broth makes an excellent addition to any plate of sliced up juicy Prime Rib.

Troubleshooting Common Issues

Here are some common issues you may encounter and how to troubleshoot them:

1. Burnt or Overcooked Prime Rib: If your prime rib is burnt or overcooked, it’s likely that the grill temperature was too high or you left it on for too long.

To avoid this issue in the future, make sure to monitor your grill temperature closely throughout the cooking process using a thermometer.

2. Unevenly Cooked Prime Rib: Uneven cooking can occur if one part of your prime rib is thicker than another or if there are hot spots on your grill.

To prevent this from happening again, try to choose a more uniform cut of meat and create an even two-zone heat distribution by placing coals only under half of the grilling surface.

3. Dry Prime Rib: A dry prime rib could be due to overcooking but also because not enough fat was left intact during trimming before grilling began; therefore basting with butter will help keep moisture locked in while adding flavor.

Storing and Reheating Leftovers

Don’t worry; they can be just as delicious the next day! To store leftover prime rib, wrap it tightly in plastic wrap or aluminum foil and place it in an airtight container. Store it in the refrigerator for up to three days.

When reheating leftover prime rib, there are a few things to keep in mind. First of all, make sure that you reheat it slowly and gently so that the meat doesn’t dry out or become tough.

You can do this by placing the sliced meat on a baking sheet lined with parchment paper and heating it at 250°F (120°C) for about 10-15 minutes.

Alternatively, you could also reheat your leftover prime rib on low heat using a skillet or griddle pan until heated through but not overcooked.

Remember not to microwave your leftovers as this will cause them to lose their texture and flavor quickly!

By following these simple steps for storing and reheating your grilled Prime Rib properly -you’ll be able to enjoy its succulent taste even after several days!
