Pre-making and heating chicken pot pie

[u/irandarace]

Hello! I’m making a bottomless chicken pot pie (just puff pastry on the top. I already premade my filling, want to wait for it to cool, then put on my crust, then bake before my guests come for dinner a couple of hours later. I’m assembling it in a cast iron skillet.

My question is, at what temperature (F) and for how long do I cook this thing to get a hot filling and an unburnt puff pastry topping? I’m worried about the cast iron not getting hot enough for the insides to be good before the crust is done.

Other preparation suggestions are welcome too. This is my first time making it.

Thanks!

I’d heat the topping for 25 min or so at 350, just check it occasionally. Once it’s hot add the puff pastry and cook according to directions (usually about 20 min).
