A good rule of thumb for Prime Rib is to have about 1 lb per person. You can adjust roast's doneness to personal preference. Keep in mind it will continue to cook while resting so I like to pull it early so it doesn't overcook. For medium rare (which is optimal, in my opinion) roast the Prime Rib at 250°F for 24-26 min per lb and then rest for 30 minutes. Since all ovens are different, using a meat thermometer is KEY.Rare: 120–125°F, red interior fading to pink at edgesMedium rare: 130–135°F, pink color with nearly red centerMedium: 135–140°F, mauve throughoutWell-done: 145°F or higher, brown, no pink

Prime Rib 1 Liberally cover your roast with kosher salt and pepper. Let it sit in the fridge, uncovered, for 12-24 hours. Let it get to room temperature for 2-3 hours before cooking. While your Prime Rib gets to room temperature, start preparing your Au Jus. Regular Searing Option 2 Preheat a pan on high for 2-3 minutes. Lower heat to medium high. 3 Add some olive or avocado oil. 4 Sear it on all sides until perfectly browned. About 10-15 minutes. 5 Place it on your roasting rack and roast at 250℉ in the middle rack of the oven for 24-26 minutes/lb. For a medium rare cook, you want it to reach 118℉-120℉ (it will continue to raise about 5-10 more degrees while resting). This will take about 4-5 hours. Let it rest 20-30 minutes. Reverse Searing Option 6 For reverse searing you will be searing at the end instead of the beginning. Place your room temperature Prime Rib on a roasting rack at 250℉ in the middle rack of the oven for 24-26 minutes/lb. For a medium rare cook, you want it to reach 118℉. Let rest for 20-30 minutes.At this point you can either:Crank the heat up to 475°F-500°F and put it back in the oven until it develops a golden crust, about 6-10 minutes.Preheat a pan on high for 2-3 minutes. Lower heat to medium high. Add some olive or avocado oil. Sear it on all sides until perfectly browned, about 10-15 minutes. Au Jus 8 Rub the bones and short rib with the tomato paste and roast at 400°F for 10-12 minutes. 9 Add your shallots and onions to a heavy pot with a bit of olive oil. Let them caramelize on medium low heat for about 45 minutes, stirring frequently. 10 Add the rest of your ingredients to the heavy pot and simmer for 2-4 hours while your roast cooks. Add water as needed. Strain. Horseradish 14 Mix the ingredients.View original recipe
