Calzones resemble folded-over pizzas, and like pizza, they taste best when they come piping hot out of the oven. Leftover calzones can be reheated without drying out the centre or making the crust soggy. The time it takes to reheat your calzone will depend on the amount of filling and whether you had your calzone stored in the freezer or refrigerator. To prevent food poisoning, reheat it to at least 73.9 degrees Celsius.
Heat the oven to 204 degrees Celsius for 20 minutes.
Place the calzone directly from the refrigerator, unwrapped, onto the baking tray.
Wrap frozen calzones with aluminium foil before reheating.
Bake the calzone for 15 to 18 minutes or until it's hot in the centre and the crust becomes golden brown.
Insert the probe of a food thermometer into the centre of the calzone and remove it from the oven when the middle reaches 73.9 degrees Celsius.
