You can also heat the pizza you left out overnight with a splash of water to fight bacterial growth. However, if you have left it out for too many hours, then even heating it won’t save your problem.

So, a simple answer to whether you can leave the pizza out overnight is that it is safer NOT to leave it, but if you do, do a little taste and sniff taste and then heat it to kill any bacterial growth.

So, instead of leaving it out and having to throw it in the morning, it’s better to store it in the fridge so it’s safe to eat whenever you want.

So, we are going to give you a few tips for storing pizza properly.

  • Pack the pizza up and store it in the fridge or freezer as soon as you eat it.
  • Use paper towels or foil to wrap the pizza slices so that once you seal them in the container, all the moisture and goodness stay inside.
  • Make sure that the pizza is in an airtight container, or it can get dry.
  • You can eat properly refrigerated pizza even after four days, but after that, it will start to go bad. Do you want to save it longer? Consider freezing it in the same way you will put it in the fridge.

A guide on how to properly reheat leftover pizza.

If your pizza was left out for the whole night, then there is a good chance that it will be spoiled. However, if you still have hope and think that the pizza has hope, then you should reheat it until there is a lot of steam in the pan.

Many people think that heating food that has been left out can kill bacteria and save the food from going bad.

This statement is true, but it won’t work if your food has already started to go bad. It will only work if your food is still edible and you want to increase its life. 

So, the best way to reheat the pizza that you left out is:

  • Preheat your oven, your skillet, or pan, and then take your pizza. Splash some water on it (don’t soak wet it), put it on a foil that is big enough to wrap it whole, and then put it in the oven, pan, or skillet.
  • Leave the pizza for a good 10-15 minutes on low heat to warm up properly and kill all bacteria.
  • Once 15 minutes are passed, you can take the pizza and check if it’s too soggy but steaming hot; then, you can remove the foil and put it in the oven, pan, or skillet to burn the excess water. It will hardly take 5 minutes. But your pizza will feel like freshly baked.
  • Microwave is another option to heat pizza, but instead of preheating the microwave, just pack the pizza in foil, splash it with water, and put it in the microwave for 6-10 minutes.

How can you tell if leftover pizza is bad?

Trust me, when your pizza has gone bad, you’ll know. But if you still want pointers to identify a bad pizza, here are a few:

  • If, as soon as you open the box, container, or pack of your pizza and are met with an unpleasant smell, your pizza has gone bad.
  • If you see mold and fungus on the pizza that wasn’t there the last time, your pizza has gone bad.
  • If there is any discoloration, your pizza has gone bad.
  • If you got a gut feeling that the pizza isn’t worth eating or safe to eat. Trust your gut because your pizza has gone bad.
