This rotisserie prime rib is the best roast I have ever had. It’s tender, flavorful and cooked to just the right temperature. To add another layer of flavor I made a homemade horseradish sauce which gave this dish a nice kick of freshness and spiciness elevating the it to a whole other level! Let me show you how to grill the perfect prime rib with this easy to follow recipe.
Prepare the Prime Rib
For this recipe I purchased a bone-in prime rib which I kept on. The flavors from the bone marrow will add great flavors to this already flavorful cut. Clean up the meat from any outer fat caps and clean up any loose pieces. Coat the prime rib with some olive oil for the binder and then go very heavy with coarse kosher salt and pepper. Do not be afraid to go heavy on the seasoning. Some of it will burn or fall off during the roasting process. Make sure to cover all sides of the prime rib.
Next, latch the prime rib onto the rotisserie skewers and it’s time to get the grill ready. I decided not to truss my prime rib since the skewers were holding it firmly. If your prime rib is loose or not held properly on the skewer, I highly recommend trussing the entire cut to hold together.
How to grill the perfect rotisserie prime rib
Preheat the grill to 250 degrees for direct heat. Depending on the size of your roast, the total grill process will take about 2 hours. Once the internal temperature reaches 120 degrees, it’s time to remove from the grill. At this internal temperature, the prime rib will be perfectly cooked to a medium rare which is ideal for this cut of meat. If you cook any longer, the meat will be tough and chewy. A medium rare will have the succulent red middle and slightly more done outer parts for those that prefer more cooked meat. Trust me!
Let it rest for 10-15 minutes allowing the juices to redistribute throughout the prime rib.
How to make the best homemade horseradish sauce
This sauce is savory, fresh and spicy from the horseradish. It’s the perfect compliment to a slice of prime rib.
In a mixing bowl, add freshly grounded horseradish, sour cream, mayo, a splash of apple cider vinegar and chopped chives. Mix the ingredients together until the liquid has a smooth consistency. Set in the fridge while the prime rib finishes roasting.
Carve into that flavorful and tender rotisserie prime rib, serve with a side of the horseradish sauce and enjoy!
