Reheating Your Leftover Pizza

There are quite a few different ways of reheating your pizza, so just pick one and go for it:


A super easy way to reheat your pizza is by using a microwave, simply placing your pizza into the microwave and blasting it for between 15-30 seconds, and checking the temperature of the pizza after each short blast.

Placing a glass of water in your microwave will also ensure your pizza doesn’t go soggy!


Preheat your oven to 200 degrees Fahrenheit and cook it for 15 minutes, check it’s hot all the way through before you eat it, but this is a great way to reheat your pizza.


Another great way to reheat your pizza is to use a non-stick frying pan and using a lid!

This lid will help to warm the top of your pizza quicker, as well as preventing the bottom of the pizza from burning too quickly too!


So to summarise, you should be cautious when it comes to storing and reheating your pizza, but as long as you follow these rules, you should have no issues!
