Try this Instant Pot Whole Blackened Chicken recipe
Blackening seasoning carries the burden of creating deep, savory complexity while protecting the poultry underneath from scorching. Paprika, garlic powder, onion powder, and dried herbs form a dry rub that reacts with surface fats during the searing stage, initiating the Maillard reaction that builds savory depth before the lid ever seals. Water in the inner pot creates steam pressure that cooks the meat quickly, but steaming alone will strip away the crisp exterior unless moisture management is handled with precision. Scaling this method requires keeping the poultry weight strictly between three and four pounds, because larger birds will not fit safely inside standard six-quart pressure cookers and smaller ones will overcook in fifteen minutes.
Pressure cookers trap moisture inside a sealed chamber, which transforms dry spice crusts into soggy layers unless managed properly. Searing the bird in a combination of unsalted butter and extra-virgin olive oil before pressure cooking renders out subcutaneous fat, creating a lipid barrier that holds the seasoning against the skin. Olive oil raises the smoke point of the butter solids so the pan can reach the 400 degrees Fahrenheit needed to toast the spices without burning the milk solids instantly. Once pressure cooking concludes, check that the internal temperature reaches 165 degrees Fahrenheit at the deepest part of the breast using an instant-read thermometer. Transfer the bird to a hot cast-iron skillet for three minutes after pressure release if the skin requires extra crisping.
