If possible, bake the pitas on a pizza stone or cast-iron skillet - or something that will get very hot and hold onto that heat.
When ready to bake, preheat your oven and the stone/skillet at the same time to 475-500 degrees fahrenheit. You’ll want the oven and the pan to be very hot. This is key to getting them to puff up.
Once preheated, carefully remove the pan and place the rolled out dough on top of the pan, and quickly put it back in the hot oven. You may not have room for all of them to cook at once, but you can do it in sessions. Watch the oven closely to see when they are fully puffed up and beginning to brown on top. This takes about 5-6 minutes. You can even set the oven to broil for a minute to get the tops crispier. If you do this, watch it very closely!
Once all the pita pockets are done, remove them from the oven and place on a cooling rack.
You can eat them hot or let them cool before slicing them in half and filling them with your desired fillings.
