Step 1

Season the beef with salt and pepper on all sides.

Step 2

Heat the olive oil in the Instant Pot set on the sauté setting. Sear the beef on all sides until nicely caramelized. Set aside.

Step 3

Add the onion and garlic to the Instant Pot and cook until just fragrant, about 2 minutes. Turn off the Instant Pot.

Step 4

Add the thyme and the beef stock to the Instant Pot, stirring with a wooden spoon to bring up the fond. Add the trivet to the Instant Pot, then add the beef.

Step 5

Cook on high for 3 minutes, then reduce to the warm setting. Keep the pot on warm for 3 hours. Take the internal temperature of the beef: when it's at 135 degrees Fahrenheit, it will be perfectly medium-rare.

Step 6

Remove the beef from the Instant Pot and strain out the juices. Return to the Instant Pot and cook on the sauté setting to reduce to desired thickness.
