Salt prime rib roast with kosher salt the day before you plan on cooking it. Store it in the refrigerator overnight, uncovered.
1 Tbsp. Kosher salt, 8 lb. Prime Rib Roast
When ready to roast, preheat your oven to 200°F. Place the prime rib roast on a roasting pan with a rack.
Rub the roast all over with olive oil and season with freshly cracked black pepper according to taste.
2 Tbsp. Olive oil, 2 tsp. black pepper
Place the roasting pan in the preheated oven. Cook until the roast reaches 120°F (medium-rare) internally as read by a meat thermometer, about 4 hours. Time will vary depending on the size of the roast and whether you are using a boneless or bone-in roast. Use an instant read thermometer and always remove the roast from the oven 5 degrees below your desired degree of doneness, as it will continue to cook once removed and reach the proper temperature.
Remove the roast from the oven. Tent with foil for 20 minutes.
Turn oven temp up to 500°F. Once it reaches temperature, remove the foil from the roast and place the roast back into the oven. Cook until the outside browns and crisps up, about 10-15 minutes.
Transfer roast to cutting board. Let it rest for 15 minutes, then slice and serve!

It is always best to use a meat thermometer to make sure your Prime Rib is done perfectly to your liking.
The night before roasting the prime rib, unwrap the beef and set it in the refrigerator. Keep it uncovered on the sheet pan with a rack. This allows the surface moisture to evaporate and will guarantee a beautiful brown crust when you sear it.
Three hours before roasting, take the beef out and place it on a sheet pan (to catch any juices) and keep it at room temperature. This step is key to an evenly roasted prime rib recipe.
Make sure you let the prime rib rest for at least 15-20 minutes before carving
