In a small bowl whisk together the olive oil, lemon juice and zest, garlic, garlic powder, rosemary, and sea salt.

Add pork tenderloin to a large zip top bag. Pour in marinade and massage to coat. Seal tightly. Marinate for at least 20 minutes, preferably overnight.

Add the avocado oil to the Instant Pot vessel and turn to Saute. Remove pork pieces from marinade, reserving marinade.

When oil shimmers, add the pork tenderloin to sear (do not crowd the pot). Cook 2 minutes, then flip and cook another 2 minutes.

Pour in broth and reserved marinade. Close and lock the lid. Set time to 50 minutes and pressure to HIGH.

When the time is up, allow pressure to release naturally or do a quick release.
