Equipment

Ingredients

  • 3 lbs. boneless beef rib roast
  • sea salt to taste
  • black pepper to taste
  • 1 cup unsalted beef stock
  • ½ cup red wine Merlot, shiraz, pinot noir or your favorite red wine
  • 3 Tbsp. vegetable oil
  • 3 Tbsp. all-purpose flour
  • optional: sprigs of fresh herbs we recommend rosemary, thyme, or parsley

Instructions

  • Score the fat cap of a 3 lb. boneless beef rib roast.

  • Generously season your roast on all sides with sea salt and ground black pepper. Give it a good coating, even if it seems like too much salt. Trust us, you want to coat it all over!

  • Place the trivet in the Instant Pot. Place the roast in the trivet. Add 1 cup unsalted beef stock and ½ cup red wine.
    Optional step: Add a few sprigs of fresh herbs to the Instant Pot, such as rosemary, thyme, or parsley.

  • Lock the lid in place and make sure the vent is in the “sealing” position. Choose the manual setting, LOW pressure, and set the timer for 5 minutes.
  • Once the 5 minutes is done, do not remove the lid or release the pressure. Leave the roast in the pot for 30 more minutes. The Instant Pot will automatically switch modes to the “keep warm” setting.
  • Once 30 minutes are up, carefully open the pot and insert a meat thermometer at the thickest part of the rib. It should read approx. 115°F. If the temperature is too low, put the lid back on and leave it on warm for 5-10 minutes, then check again.
    Note: When searing the roast, the temperature will rise, so you want to pull it out of the pot before it cooks to your desired temperature.
  • Remove the roast to a plate. Strain the liquids from the Instant Pot into a cup, and set aside.
  • Remove the trivet from the Instant Pot. Select the highest saute setting. Add 3 Tbsp. vegetable oil to the pot. Place the prime rib roast back and sear it until it browns on all sides, approximately 10-15 minutes.
    Note: The prime rib should have a nice crust on it. If you prefer, you can brown the roast in a cast-iron skillet on the stovetop.
    3 Tbsp. vegetable oil
  • Insert the meat thermometer into the thickest part of the prime rib and make sure you cook it to your desired degree of doneness. For quick reference, the temperature for medium-rare prime rib is 135°F and 145 for medium.
  • Remove the roast to a platter, tent with foil, and let it rest for 15 minutes. Meanwhile, add the strained liquids back to the pot, then add 3 Tbsp. all-purpose flour and stir to make a gravy. Enjoy!

Notes

  • Reverse searing prime rib: We recommend you reverse sear prime rib as we outline in the steps above. 
  • Beef stock vs red wine: If you would prefer, you can substitute the red wine for additional beef stock.
  • Use a meat thermometer: Always use a meat thermometer for accuracy to achieve your desired degree of doneness.
  • Let it rest: Always let the prime rib sit for 15 minutes before carving.
  • Slice against the grain: For the most tender prime rib, slice the beef against the grain.
