Yes, these puff pastries can be air-fried as well.  Air fryer is nothing else but a small countertop convection oven, which uses a fan to circulate hot air. Any recipe which is baked can be air fried easily. Only point to remember when using air fryer the total volume of air fryer in which the hot air is circulating is very less compared to oven, if similar temperature used for air fryer as convection oven then food will not cooked properly. So, what I follow with regards to temperature in different equipment’s, is to reduce the temperature by 30-40oF to what is needed for regular baking for convection oven and further reduce 30-40-degree F temperature for air fryer. So, if this recipe calls for 380oF for normal baking then, for air frying reduce the air frying temperature to 300-degree F. Air-fry puff pastries for approximately 18-20 minutes @ 300oF.
