For an even more intense flavor, consider scoring the fat cap of the prime rib in a crosshatch pattern before applying the garlic, salt, and mustard. If you don't have fresh rosemary, you can substitute 1 tablespoon of dried rosemary, but fresh is highly recommended for its superior aroma and taste. Use a reliable meat thermometer to ensure accurate temperature readings. Oven temperatures can vary, so relying solely on time is not recommended. During the resting period, the internal temperature of the roast will continue to rise slightly (carryover cooking). Take this into account when determining your desired doneness. Serve with your favorite sides, such as roasted vegetables, mashed potatoes, or Yorkshire pudding, for a complete and memorable meal.

Follow The Directions
01
StepPreheat your oven to 450 degrees F (230 degrees C). (5 minutes)
02
StepCreate small incisions across the surface of the prime rib. Insert the garlic slices into these cuts. Season the entire roast generously with kosher salt. (10 minutes)
03
StepApply a thin, even layer of Dijon mustard over the entire roast. Sprinkle the chopped rosemary leaves liberally over the mustard coating, ensuring they adhere well. Place the roast, bone-side down, in a roasting pan. (5 minutes)
04
StepBake in the preheated oven for 30 minutes. Reduce the oven temperature to 350 degrees F (175 degrees C). Insert a meat thermometer into the thickest part of the meat, being careful not to touch the bone. (35 minutes)
05
StepContinue cooking until the meat reaches your desired doneness. For medium, aim for an internal temperature of 145 degrees F (65 degrees C), which should take approximately 1 1/2 hours. Adjust cooking time accordingly for different levels of doneness. (90 minutes)
06
StepRemove the roast from the oven, tent it loosely with a double layer of aluminum foil, and let it rest in a warm place for 10 to 15 minutes before carving. This allows the juices to redistribute, resulting in a more tender and flavorful roast. (15 minutes)
