. Close the lid and cook at High Pressure for 5 minutes. Turn off the heat and full Natural Release (roughly 7 - 8 minutes). Open the lid carefully. Remove the chicken and check for an internal temperature with a food thermometer
to make sure it's between 161°F – 163°F (See Notes). Rest the chicken breast on a plate for 5 – 8 minutes.
