When purchasing or making multiple pizzas, you may need to freeze one to eat later. Reheating the frozen pizza requires a method that will crisp up the crust. Heating a frozen pizza in the microwave may leave you with a chewy, soggy crust. Instead, reheat the pizza using the dry heat of a conventional oven to crisp the crust and melt the cheese. With the proper temperature and techniques, you can reheat an entire pizza or just individual slices.
Allow the pizza to thaw on a plate on the counter for 15 minutes.
Heat the oven to 204 degrees Celsius.
Place the pizza on a perforated pizza pan.
Set the pizza on the centre rack in the preheated oven. Allow the pizza to reheat for 10 minutes. When the cheese has melted on top, remove the pizza from the oven.
Preheat the oven to 204 degrees Celsius.
Place one or more frozen pizza slices onto a piece of aluminium foil.
Set the aluminium foil on the centre rack of the oven.
Check the pizza slices after five minutes in the oven. When the cheese has melted, remove the slices from the oven.
