Prep Time10 mins
Cook Time1 hr 30 mins
Total Time2 hrs
Servings: 8 SERVES
- 6 pound (3 kg) standing rib roast, (4 bone rib roast)
- 2 heads garlic, unpeeled and halved horizontally (unpeeled keeps it together)
- 1/2 cup unsalted butter
- 5 cloves garlic, minced
- 1 tablespoon coarse salt
- 1 teaspoon black pepper
RED WINE JUS:
- 3 cups low sodium beef stock, (or broth)
- 2 cups red wine
- 1 tablespoon cornstarch, (cornflour) -- optional for a thicker sauce.
PRIME RIB: Take prime rib out of the refridgerator atleast 2 - 3 hours before cooking to bring to room temperature. Pat dry all over with paper towel.
PREHEAT: STANDARD oven to 460˚F (240°C) | FAN/CONVECTION 430˚F (220°C).
GARLIC BUTTER: Mix together the butter and garlic and 1/2 tablespoon of salt in a small bowl until combined.
SKILLET OR ROASTING PAN: Arrange garlic halves in a heavy-based pan or cast-iron skillet. Spread 2 tablespoons of garlic butter on the underside of the beef (bone-side) to completely coat. Place the roast, bone-side down, in the pan/skillet on top of the onion and garlic halves (the bones create a natural roasting rack for the meat). Spread another 2-3 tablespoons of garlic butter on the top and sides, rubbing into the flesh. Coat well.Season with remaining salt and pepper.
ROAST: For 20-30 minutes or until the roast has nicely browned.
GARLIC BUTTER 2: Carefully remove roast from oven. Spread with remaining garlic butter.
REDUCE OVEN TEMPERATURE: STANDARD oven 250°F (120°C) | FAN/CONVECTION oven 220°F (100°C).
COVER WITH FOIL and continue to slow roast for 1 - 1 1/2 hours, basting every 20-30 minutes with the pan juices, until reaching your desired preference. Internal temperature should read 118°F | 48°C for med/rare. (TIP: Start checking internal temperature after 45 minutes of roasting. Continue to keep checking with each baste to ensure it doesn't over cook.)
Once cooked to your liking, allow to rest for 20 minutes. The roast will continue to cook as the juices inside settle, raising the internal temperature to 130°F | 55°C for a perfect medium-rare prime rib.
REST: Transfer roast to serving plate, tent loosely with foil and let rest for 20 - 30 minutes. Internal temperature will rise to 125°F (52°C) for medium rare.
SLICE AND SERVE with Red Wine Jus/Sauce.
RED WINE JUS: Place skillet with pan juices and the cooked garlic halves left in the pan on the stove top over high heat. Stir in 2 1/2 cups of the beef stock and all of the wine. Bring to a fast simmer for 10 minutes until iquid has reduced by roughly half.
REDUCE HEAT to medium. Whisk cornstarch (cornflour) into the remaining beef stock. Whisk half of the mixture into the red wine jus. Sauce will begin to thicken. Whisk in remaining cornstarch mixture for a thicker jus. Strain jus into a bowl, pressing garlic juices through the strainer, then pour jus into serving jug.
SIDE DISH SUGGESTIONS: Creamy Mashed Potatoes, Buttery Mashed Cauliflower, Buttery Sautéed Green Beans, Balsamic Roasted Mushrooms, Roasted Brussels Sprouts with Bacon.
Internal Temperature of Cooked Prime Rib will rise while it rests by 5-7°F (or 3-4°C) every 10 to 15 minutes or so. Take out of the oven just before reaching your desired doneness, as below:
For larger roasts, add 10 minutes extra roasting time for each additional 2 pounds (1 kg). Start checking the internal temperature early, as suggested in the recipe, to be sure. Every oven is different.
PRIME RIB SELECTION OR STANDING RIB ROAST. Buy a good quality cut from your butcher. They are normally larger and fresher when compared with supermarket cuts.
Choose a cut with the bones still attached and trimmed (or frenched: bones scraped clean of excess fat and meat). You can also buy a prime rib roast with bones removed and reattached with string if you wish! Bones = a natural roasting rack for the meat.
- Rare: 120°F (49°C). Remove from oven at 115°F (46°C) internal temp.
- Medium Rare: 125°F (51.7°C). Remove at 48°C / 118°F internal temp.
- Medium: 130°F (55°C). Remove at 123°F (51°F) internal temp.
- Medium Well: 135°F (57°C). Remove at 127°F (53°C) internal temp.
