Prime Rib seems so intimidating to cook, but in all honesty, it’s easier than roasting a turkey. There’s no brining, stuffing a cavity, flipping halfway or injecting with marinade. Cooking the most tender Prime Rib only uses one cooking rule – slow ‘n low. All you need is time.
- 1 (6-10 pound) standing rib roast
- salt and freshly ground black pepper
- 1/3 cup miso paste (or 1/2 cup Miso & Easy), divided
- 5 large carrots, halved
- 8 stalks celery, halved
- 2 onions, halved
- 1 cup red wine
- 2 cups good quality beef stock
- Heat the oven to 250F. Season the rib roast on all sides with salt and pepper. Rub just 2-3 tablespoons of the miso (keep the rest of the miso for the Au Jus) on all sides of the rib roast. Place rib roast in a large roasting pan. Scatter the vegetables all around the roast.
- Roast for 17-20 minutes PER POUND or until temperature of the middle of the roast is 130F (medium-rare to medium). Turn the broiler to high and let the roast brown a bit on the outside, for about 5 minutes. Transfer roast to cutting board, carefully untie the bones from roast. Cover loosely with tin foil. Rest for 20 minutes.
- While roast is resting, make the Miso Jus. Keep the vegetables in the roasting pan but discard all but 1 teaspoon of the fat. Place the roasting pan 2 burners set on high heat.
- Pour in the red wine and cook until wine is reduced by half. Use a wooden spoon to scrape up the bits. Whisk in the beef broth and 2 tablespoons of miso paste (or 3 tablespoons Miso & Easy). Turn heat to medium-low and simmer for 15 minutes. Add any juices accumulated from the rib roast on the cutting board. Turn off heat.
- Strain the jus with mesh strainer, pressing down with wooden spoon to extract out all the juice from the vegetables. Carve the roast, serve with the jus.
