Using Sauté setting on Instant Pot, add the olive oil and generously seasoned pork loin.  Brown both sides of the loin for approximately 7 minutes on each side.

After the loin is browned, remove it from the Instant Pot and add mushrooms, carrots, butter and seasonings.  Sauté for approximately 10 minutes.

Thinly slice the pork loin, then add the loin,  potatoes, chicken broth, soy sauce, and other seasonings to the mushroom and carrot mixture in the pot.

Layer the potato chunks on top for best texture and taste.

Place the Instant Pot on the manual setting and cook on high for 5 minutes, then allow to naturally release for 10 minutes.

After the steam release, the pork loin is ready to serve!
