The Instant Pot makes quick work of arm roast, so quick in fact that you’ll be enjoying tender, flavorful shredded beef in less than 2 hours (including prep and cook time!).
Sprinkle the all-purpose seasoning all over each arm roast chunk, making sure to coat the exterior evenly. Add the seasoned beef arm roast chunks to the Instant Pot.
Set your Instant Pot to High Pressure for 45 minutes. It will take around 10-12 minutes to come to pressure. When the beef arm roast has finished cooking, let the pressure naturally release.
