Bone-In Prime Rib Roast Recipe

Nothing says celebration quite like a standing rib roast. A bone-in Savenor’s prime rib roast, seasoned with our Prime Beef Rub and roasted low and slow at 325°F over carrots, onions and beef stock, gets basted every half hour so the pan juices build as it cooks. Here’s how to cook a prime rib roast of any size — from an intimate 2-rib dinner to a full 7-rib holiday centerpiece.

Ingredients

  • 1Savenor’s 4-Rib Prime Rib Roast (about 10 lb)
  • 2 tbspoil
  • ¾ cupchopped carrots
  • ¾ cupchopped onions
  • ½ tspdried thyme
  • 2 cupsbeef stock
  • To tasteSavenor’s Prime Beef Rub (season generously)

Instructions

  1. Preheat the oven
    Preheat your oven to 325°F.
  2. Prepare the roast
    Pat the roast dry with paper towels. Rub the exposed ends of the meat with oil, then season generously all over with Savenor’s Prime Beef Rub.
  3. Set up the pan
    Place the roast bone-side down, fat side up, in a roasting pan. Pour 2 cups of beef stock into the bottom of the pan to keep the drippings from burning and to form the base of the pan juices.
  4. Add the vegetables
    Scatter the chopped carrots and onions around the roast and sprinkle them with the dried thyme.
  5. Roast and baste
    Place the pan on the lower-middle rack of the oven. Roast, basting the meat and vegetables with the pan juices every 30 minutes. Plan on roughly 15–18 minutes per pound — about 2½–3 hours for your roast.
  6. Check the temperature
    Begin checking the internal temperature with an instant-read thermometer in the thickest part of the meat, away from the bone, after 2 hours. Remove the roast when it reaches 120°F for rare, 125–130°F for medium-rare, or 135–140°F for medium.
  7. Rest and slice
    Transfer the roast to a cutting board or platter. Remove any trussing strings and let it rest, uncovered, for 20–30 minutes before slicing.

Doneness temps: 120°F rare · 125–130°F medium-rare · 135–140°F medium. The temperature keeps rising a few degrees while the roast rests, so take it out as soon as it hits your target. Times are a guide — always go by the thermometer.

Boneless roasts: Follow the same method, but place the roast on a rack inside the pan and tie it with butcher’s twine to help it hold its shape. Plan for 14–16 minutes per pound, and begin checking the internal temperature [CONFIRM: when to start checking].
