It might seem obvious, but it’s important to remember that any recipe you’re cooking with frozen meat will need extra cooking time.
Various factors can affect how long it takes for a pressure cooker to come up to pressure, seal, and then actually begin the cooking time. One of those factors is the temperature of the ingredients.
I recommend starting with individually frozen chicken pieces. When chicken is frozen all together in one large chunk, it generally won’t cook very evenly or turn out as well.
From frozen chicken breasts to thighs, whole legs, tenders … even the whole chicken. You really can cook any part of a frozen chicken in an Instant Pot, without any thawing at all!
