• Trim excess fat from the prime rib and season it with salt, pepper, and herbs/spices.
• Calculate the cooking time to be approximately 15 minutes per pound and maintain a steady medium-high heat.
• Monitor the temperature closely using a reliable meat thermometer and aim for an internal temperature of 135°F (medium-rare) or 145°F (medium).

Choosing the Right Rotisserie and Setup

You should select a rotisserie rated for at least 20 pounds and ensure it's securely attached to your grill for stable and even cooking. When choosing a rotisserie, consider the size and weight of the meat you'll be cooking. Look for accessories such as adjustable spit forks to securely hold the meat in place and a counterbalance kit to ensure smooth rotation. Additionally, ensure that the rotisserie is well-maintained by regularly cleaning the spit rod and forks to prevent rust and corrosion.

Rotisserie safety is paramount. Always follow the manufacturer's guidelines for setup and usage. Ensure that the rotisserie is securely attached to the grill and that the motor is functioning correctly before each use. It's essential to place the rotisserie in an open, well-ventilated area and to keep children and pets away from the grill while it's in use. Additionally, use heat-resistant gloves when handling the rotisserie and always wait for the equipment to cool down before attempting any maintenance or cleaning.

Preparing the Prime Rib for Cooking

To prepare the 18-pound prime rib for cooking on the rotisserie, trim excess fat and season the meat generously with salt, pepper, and your choice of herbs and spices. Trimming the fat is essential to ensure that the prime rib cooks evenly and the flavors aren't overwhelmed by excessive fatty portions. Use a sharp knife to carefully remove any large pockets of fat on the surface of the meat, leaving a thin layer to enhance flavor and juiciness.

After trimming the fat, it's time to season the prime rib. Generously coat the entire surface of the meat with salt and freshly ground black pepper. This forms the base of the flavor profile. Additionally, consider using herbs and spices such as rosemary, thyme, garlic, or a blend of your choice to complement the rich taste of the prime rib.

Allow the seasoned prime rib to rest at room temperature for about 30 minutes before placing it on the rotisserie. This brief resting period allows the seasoning to penetrate the meat, enhancing its flavor throughout. Properly trimming and seasoning the prime rib sets the stage for a mouthwatering and perfectly cooked rotisserie prime rib experience.

Calculating the Cooking Time

The cooking time for an 18-pound prime rib on the rotisserie is approximately 15 minutes per pound at a consistent medium-high heat. However, there are a few crucial factors to consider for a perfectly cooked prime rib.

First, ensure that your rotisserie maintains a steady medium-high heat throughout the cooking process. If there are fluctuations in temperature, it can affect the overall cooking time and the evenness of the doneness. To achieve this, you may need to make minor adjustments to the rotisserie's temperature settings as needed.

Another essential aspect is rotisserie maintenance. Before starting the cooking process, double-check that your rotisserie is clean and in good working condition. Any malfunction or debris buildup can impact the cooking time and the final result. Additionally, make sure the rotisserie is properly lubricated to avoid any hitches during the cooking process.

Monitoring the Rotisserie Cooking Process

During the rotisserie cooking process, monitor the temperature closely to ensure even cooking of the 18-pound prime rib. Consistently maintaining the right temperature is crucial for achieving a juicy and tender prime rib. Use a reliable meat thermometer to check the internal temperature regularly. For medium-rare doneness, aim for an internal temperature of 135°F (57°C), while medium requires 145°F (63°C).

In addition to temperature control, the basting technique plays a crucial role in keeping the prime rib moist and flavorful. Prepare a basting liquid of your choice, such as a mixture of melted butter, herbs, and garlic, and apply it using a basting brush at regular intervals. This not only introduces extra flavor but also helps to keep the meat from drying out during the cooking process. By closely monitoring the temperature and employing a consistent basting technique, you can ensure a perfectly cooked rotisserie prime rib that will impress your guests.

Resting and Carving the Perfect Prime Rib

Once the prime rib has finished cooking, let it rest for 15-20 minutes before carving to allow the juices to redistribute and ensure a tender, flavorful result.

This resting period is crucial as it allows the residual heat to finish cooking the roast evenly while the juices, which have been forced to the center during the cooking process, redistribute throughout the meat.

To maintain the perfect doneness, it's essential to monitor the internal temperature, ensuring it reaches the desired level before resting.

When carving, use a sharp carving knife to achieve clean, even slices. Aim for a thickness of around half an inch to showcase the marbling and tenderness of the meat.

For presentation, arrange the slices on a warm platter and consider serving with a flavorful jus or horseradish cream.

Seasoning options such as a simple salt and pepper rub, or a herb-infused crust, can elevate the flavors of the prime rib.
