(can be made up to 2 days ahead): In a bowl, combine all sauce ingredients. Stir to incorporate well. If making ahead of time, keep chilled in airtight container until ready to use.

Step 2

Slice beef into 2″ x 2″ chunks. Sprinkle kosher salt and pepper evenly onto all sides of beef pieces. Set Instant Pot to sauté mode. Add olive oil; once oil is heated, add sear beef pieces in 2 batches to avoid overcrowding. Once all sides of beef pieces are nicely browned, place all the beef into the bowl of Instant Pot.

Step 3

Pour your prepared sauce evenly over the beef. Stir to combine. Cover tightly and set pressure cooker for 1 hour. Use Instant Release method to release pressure when beef is done. Gently shred the beef with forks or tongs, allowing shredded beef to soak up the juices afterwards.
