Instructions

Score the fat cap of a 3-pound boneless beef rib roast by cutting in a cross-hatch pattern.
Generously season the roast on all sides with sea salt and ground black pepper. Give it a good coating, even if it seems like too much salt.
Place the trivet in the Instant Pot, then place the roast on top of the trivet. Add 1 cup unsalted beef stock and ½ cup red wine.
Optionally, add a few sprigs of fresh herbs.
Lock the lid in place and make sure the vent is in the "sealing" position. Choose the manual setting, low pressure, and set the time for 5 minutes.
Once the time 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 to the "keep warm" setting.
Once 30 minutes is up, open the pot and insert a meat thermometer at the thickest part of the rib. Be careful when removing the lid. The meat thermometer should read 115°F. If it is too low, put the lid back on and leave it on warm for 5 to 10 more minutes.
Remove the roast to a plate and strain the liquids from the pot into a cup. Set aside.
Remove the trivet from the pot. Select the highest saute setting. Add 3 tablespoons vegetable oil and place the prime rib roast back into the pot. Sear on all sides until it browns, approximately 10-15 minutes.
Check the temperature of the roast again to make sure it's cooked to your desired degree of doneness. For medium-rare, it should read 135°F. Tent with foil and let it rest for 15 minutes before carving.
To make the gravy, add the strained liquids back to the pot along with 3 tablespoons all-purpose flour. Stir.

Notes

If you prefer, you can sear the prime rib in a cast-iron skillet on the stove instead of in the pot.
You can substitute the red wine for additional beef stock if you prefer.
Always use a meat thermometer when checking the temperature of beef for the best results and highest accuracy.
Slice against the grain for the most tender prime rib.
Please note, you will have to add more time if you want your your prime rib medium well to well done or if you purchase a larger roast. Always use a meat thermometer to check the doneness of your roast.
