Marbling refers to the streaks and flecks of white fat throughout a cut of beef. Fat is flavor, so plenty of marbling means your roast beef will taste amazing!

The seasoning is as simple as using salt and pepper. Use plenty of sea salt and black pepper for your rub. Double-check your beef stock is unsalted, as you won’t want to oversalt your beef.

Fresh herbs like rosemary, thyme, and parsley are optional, but add a lovely flavor to the beef.

How to Make Prime Rib in Instant Pot

1. Score the fat cap of a 3-pound boneless beef rib roast by cutting the layer of fat in a cross-hatch pattern.
   
   
   Generously season the roast on all sides with sea salt and ground black pepper.
   
   Coat it well, even if it seems like too much salt. You want to make sure the whole roast is coated!
   
2. Place the trivet in your Instant Pot.
   
   Place the roast on top of the trivet.
   
   Add 1 cup unsalted beef stock.
   
   Pour in 1/2 cup red wine.
   
   Optionally, add a few sprigs of fresh herbs such as rosemary, thyme, or parsley.
   
3. Lock the lid in place, and make sure the vent is set in the “sealing” position. Choose the manual setting on low pressure, and set the timer 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 mods to the “keep warm” setting.
   
4. Once 30 minutes are up, carefully open the pot and insert a meat thermometer into the thickest part of the rib. The thermometer should read approximately 115°F.
   
   If the temperature is too low, put the lid back on and leave it on warm for 5 to 10 minutes longer, then check again.
5. Remove the roast to a plate.
   
   Strain the liquids from the Instant Pot into a cup, and set aside.
   
6. Remove the trivet from the Instant Pot and select the highest saute setting. Add 3 tablespoons vegetable oil to the pot.
7. When it heats up, add the rib roast back to the pot and sear until it browns on all sides, approximately 10 to 15 minutes.
   
8. Insert the meat thermometer into the thickest part of the prime rib. Check that it’s cooked to your desired degree of doneness. The temperature for medium-rare prime rib is 135°F.
   
   Remove the roast to a platter, tent with foil, and let it rest for 15 minutes.
   
9. Add the strained liquids back to the pot along with 3 tablespoons all-purpose flour. Stir to make a gravy.
   

And that’s it! The perfect prime rib roast, made right in your Instant Pot in less than an hour.

What could be better than cooking up a beautiful, perfectly cooked prime rib roast and freeing up all of that oven space for your best side dishes for roast beef?

Tips for Cooking Prime Rib Roast in the Instant Pot

• When searing, the temperature will rise. This is why you want to pull the prime rib out of the Instant Pot early, before it cooks to your desired temperature.
• You can brown the roast in a cast-iron skillet on the stovetop if you prefer. This is another method of reverse searing prime rib.
• The roast should have a nice crust on it as you’re searing it in the pot. Let the pot heat up first before adding the rib roast.

Reverse searing prime rib makes it easy to cook your roast to the perfect temperature and still get that beautiful crust on the outside.

• Let the rib roast rest 15 minutes before carving. This helps lock in the flavor.
• Slice against the grain when cutting for the most tender prime rib.

Prime Rib Temperatures for Tender Roast Beef

• Rare: 125°F
• Medium-rare: 135°F
• Medium: 145°F
• Medium-well: 150°F
• Well-done: 160°F

Follow this easy chart for your desired degree of doneness. Use a meat thermometer for accuracy.
