- One 14-pound prime rib bone-in roast, tied
- Kosher salt and freshly ground pepper
- 20 large sage sprigs
- 20 large thyme sprigs
- 8 bay leaves
- 8 shallots, peeled and halved
- 1 head garlic, cloves crushed, plus 4 cloves thinly sliced
- 2 cups water
- 1 onion, thinly sliced
- 3 tablespoons freshly cracked black peppercorns
- 1 cup dry red wine
- 5 cups beef stock or low-sodium broth
- 2 tablespoons all-purpose flour
- Preheat the oven to 400°. Set the meat in a large roasting pan, fat side up. Season the meat generously with salt and pepper. Around the roast, scatter 10 sprigs each of sage and thyme, 6 of the bay leaves, the shallots and the crushed garlic cloves. Pour in 1 cup of the water and roast for 45 minutes. Reduce the temperature to 275°. Roast the meat for about 2 hours and 15 minutes longer, adding the remaining 1 cup of water to the pan as the juices evaporate. The roast is done when an instant-read thermometer inserted in the thickest part registers 135°.
- Transfer the roast to a large carving board. Pour the fat in the roasting pan into a large heatproof bowl, stopping when you reach the syrupy pan juices at the bottom. Pour the pan juices into a small bowl and discard the vegetables and herbs.
- Set the pan over 2 burners and add 2 tablespoons of the reserved fat. Add the onion, peppercorns and the sliced garlic, remaining 2 bay leaves and 10 sprigs each of sage and thyme. Cook over moderate heat until the onion is softened, about 8 minutes. Add the wine and cook, scraping up any bits stuck to the bottom and sides of the pan. Pour the mixture into a medium saucepan and bring to a boil over high heat. Add the beef stock and pan juices and cook over moderate heat until slightly reduced, about 15 minutes.
- In a small bowl, whisk the flour with 2 tablespoons of the reserved fat. Whisk the paste into the saucepan and simmer the gravy until thickened, about 5 minutes. Strain the gravy through a fine sieve and keep warm until ready to serve.
- Cut the bones off the roast and slice the meat 1/2 inch thick. Cut in between the bones and serve them on the side. Pass the gravy at the table.
This juicy prime rib roast needs a powerfully structured but fruit-driven red, such as a Napa Valley Cabernet Sauvignon.
