You can use frozen chicken: if I have the foresight to pull out frozen chicken and thaw it 1-2 days in advance, I’m pretty proud of myself. But I wanted a recipe that didn’t require it. Using frozen chicken didn’t compromise flavor or texture.
For frozen chicken, set the Instant Pot to “Pressure Cook” for 15 minutes. On some models, this is the manual setting with high pressure. If using fresh chicken, reduce the cooking time by 10 minutes.
