I’ve seen a few people put their delivered pizza in the oven after everyone grabs a piece to keep it warm. I’ve also seen a lot of those people forget the pizza is in there and either have to throw it out or only noticed after they preheated their oven.
Haven’t done that yet but it’s definitely what I’ll be trying next time. Normally I just eat it cold.
I’ve heard air fryers work well too
I’ve got both, cast iron is better.
Or pizza steel for bigger pies
