1 bone-in standing rib roast (3 ribs, about 7 lb)
1 tbsp kosher salt per 2 lb of beef
2 tbsp Dijon mustard Shop
6 cloves garlic, minced
2 tbsp chopped fresh rosemary
1 tbsp fresh thyme leaves
2 tsp coarsely ground black pepper
3 tbsp olive oil

Instructions

1 One to two days ahead, pat the roast dry and season all over with the kosher salt. Refrigerate uncovered on a rack set over a tray.
2 Take the roast out 2 hours before cooking. Heat the oven to 225F (110C).
3 Mix the Dijon, garlic, rosemary, thyme, pepper, and olive oil into a paste and spread it over the fat cap and sides.
4 Set the roast bone side down in a roasting pan. Roast until the center reads 145°F (63°C). USDA recommends 145°F for beef roasts, followed by a rest of at least 3 minutes (the 30-minute rest in the next step covers it). Start checking at 3 hours and allow longer than the medium-rare time. Optional chef's note: many cooks pull prime rib at 120°F (49°C) for medium-rare, about 3 1/2 to 4 hours for 7 lb. Cooking below the USDA temperature carries more food-safety risk, especially for young children, pregnant people, older adults and anyone with a weakened immune system.
5 Take the roast out, tent with foil, and rest 30 minutes. Meanwhile heat the oven to 500F (260C).
6 Return the roast to the hot oven for 8 to 10 minutes, until the crust is deeply browned. Cut the bones away and slice across the grain.
