The prime rib itself is non-negotiable—bone-in with a thick fat cap renders into that crave-worthy crust. Source from a trusted butcher like Whole Foods or Local farms for proper marbling. Diamond Crystal kosher salt is the professional standard here (its coarse texture adheres better). Fresh herbs are mandatory—don’t even consider dried. The fat cap should be at least 1/4-inch thick for optimal rendering and crust development.

No fresh rosemary or thyme? Dried at one-third the quantity, but it won’t have the same impact. Out of smoked paprika? Chipotle powder adds a different but complementary smoke. The red wine for au jus can be substituted with additional beef broth plus a splash of balsamic for acidity. For the horseradish, prepared from a jar works in a pinch (though fresh has more bite).

The roast can rest 1-2 hours at room temp before cooking—this ensures even cooking. Leftovers keep 4-5 days refrigerated, or freeze for 3 months. Always carve against the grain for maximum tenderness, even when reheating.

Step-by-Step Instructions for BBQ Rotisserie Prime Rib Roast

Master the technique for achieving a perfectly charred crust and tender interior on your rotisserie.

Step 1: Prepare the Prime Rib Roast with Herb Rub

Pat the 5 lb Prime Rib Roast dry with paper towels, ensuring the fat cap remains intact. This step is crucial for achieving a proper sear and crust. In a small bowl, combine the 2 tbsp Kosher Salt, 2 tbsp Freshly Ground Black Pepper, minced 6 cloves Garlic Cloves, finely chopped 4 whole Fresh Rosemary Sprigs, finely chopped 4 whole Fresh Thyme Sprigs, and 1 tbsp Smoked Paprika.

Add the 0.25 cup Olive Oil and 3 tbsp Dijon Mustard to the dry rub mixture, stirring until it forms a thick paste. Massage this paste evenly over the entire surface of the prime rib, pressing it into the meat to ensure maximum adhesion. Allow the roast to sit at room temperature for 1 hour to let the flavors penetrate before cooking.

Step 2: Set Up and Preheat the Rotisserie

Prepare your rotisserie according to the manufacturer’s instructions, ensuring it is clean and properly balanced. Preheat your grill or rotisserie oven to 350°F for indirect heat. This temperature allows the meat to cook evenly without burning the exterior.

Place a drip pan directly beneath the roast to catch drippings, which can be used later for making an au jus. Ensure the rotisserie spit is securely fastened, and the roast is centered for even cooking. The fat cap should face outward to baste the meat as it turns.

Step 3: Cook the Prime Rib on the Rotisserie

Once the rotisserie is preheated, place the prime rib on the spit and begin cooking. Maintain the temperature at 350°F throughout the cooking process. Cook the roast for approximately 2 to 2.5 hours, or until the internal temperature reaches 125°F for medium-rare.

Baste the roast occasionally with the softened 0.5 cup Unsalted Butter to enhance the crust and add richness. Monitor the internal temperature using a meat thermometer inserted into the thickest part of the roast, avoiding the bone.

Step 4: Rest and Serve with Au Jus

Remove the prime rib from the rotisserie and transfer it to a cutting board. Tent it loosely with aluminum foil and let it rest for 20 to 30 minutes. This resting period allows the juices to redistribute, ensuring a moist and flavorful result.

While the roast rests, combine the collected drippings in a saucepan with the 1 cup Red Wine and 2 cups Beef Broth. Simmer over medium heat for 5 to 10 minutes, skimming off any excess fat, to create a rich au jus. Slice the prime rib against the grain, serve with the au jus, and freshly grated 1 whole Horseradish Root on the side for added flavor.

Best Sauces and Condiments for This Dish

Classic Horseradish Cream

My go-to pairing is a simple horseradish cream—mix ½ cup freshly grated Horseradish Root with 1 cup sour cream and a pinch of Kosher Salt. The sharp bite cuts through the richness beautifully. I always make extra for sandwiches the next day. 🌟

Red Wine Au Jus

Use the drippings from your rotisserie with the 1 cup Red Wine and 2 cups Beef Broth as in the recipe. Simmer until reduced by half, then strain for a smooth, luxurious dipping sauce. A splash of Worcestershire sauce adds depth.

Garlic-Herb Butter

Soften ½ cup Unsalted Butter and blend with 2 minced Garlic Cloves, 1 tbsp chopped Fresh Rosemary Sprigs, and 1 tbsp chopped Fresh Thyme Sprigs. Slather on warm slices for an herby, garlicky finish.

Smoky BBQ Sauce

For a tangy contrast, I love Stubb’s Original—its vinegar base complements the beef without overpowering. Brush on the last 15 minutes of cooking for a sticky, caramelized glaze. Avoid overly sweet sauces here.

Chimichurri Drizzle

Blend 1 cup fresh parsley, ¼ cup Olive Oil, 3 tbsp red wine vinegar, and 1 minced Garlic Clove. This bright, herby sauce adds a fresh contrast to the smoky meat. Drizzle lightly over slices. 💫

Blue Cheese Crumbles

Sprinkle ½ cup crumbled blue cheese over slices for a bold, salty kick. I prefer Maytag Blue from my local cheese shop—its sharpness pairs perfectly with the rich, smoky prime rib.
