Add 2 tbsp (28g) unsalted butter or olive oil in the inner pot, then ensure to coat the oil over the whole bottom of the pot. Carefully place the seasoned side of pork shoulder in Instant Pot. Season the other side with salt and black pepper. Brown one side for 5 minutes before flipping over, then brown the other side for another 5 minutes. Remove the browned pork shoulder, then set aside.

With Venting Knob in Venting Position, close the lid, then turn Venting Knob to Sealing Position. Pressure Cook at High Pressure for 60 minutes, then 15 minutes Natural Release.

Reduce Pressure Cooking Time: If you think Pressure Cooking the Pork Shoulder for 1 hour is too long, you can cut the pork shoulder into 2 inches cubes, then reduce the cooking time to Pressure Cook at High Pressure for 40 minutes + 15 minutes natural release.
