Is it safe to bake a pizza with a cardboard box?

You cannot put cardboard in the oven with pizza. The heat will cause the cardboard to release toxic fumes that will contaminate your food.

Why it’s bad:

The fumes released by the cardboard will make your food taste and smell terrible. They can also be dangerous to your health.

What to do instead:

To create a crispy crust on your pizza, try using a baking stone or pan instead of cardboard.

What are the dangers of putting cardboard in the oven with pizza?

There are some dangers associated with putting cardboard in the oven with pizza:

  • First and foremost, cardboard is combustible. This means that if there is any kind of fire in the oven, the cardboard will ignite and create a dangerous situation.
  • Additionally, cardboard is made from paper which can cause burns if it comes into contact with heat.
  • Again using cardboard to cover your pizza is not a good idea because it can cause the cheese on the pizza to burn.
  • Finally, because cardboard is made from recycled materials, it can create an unhealthy environment inside the oven if left there too long. 

How to safely put cardboard in the oven with pizza?

If you’re putting cardboard in the oven with your pizza, there are a few things you need to keep in mind.

  • First, ensure the cardboard is clean and free from food particles or grease.
  • Second, make sure that the cardboard is not too big. It should be about the same size as your pizza.
  • Third, ensure that there is plenty of space between the top of the oven and the cardboard so that heat can circulate freely.

Frequently Asked Questions

Can You Put Cardboard In The Oven If You Wrap It In Aluminium Foil?

Some people think it’s possible, but others say it’s not a good idea. The aluminum foil will help to protect the cardboard from getting too hot. Still, some argue that it can create an uneven cooking surface.
It’s up to you whether or not you want to try this method, but be sure to follow the safety guidelines first!

What temperature is safe to put cardboard in the oven?

The safest temperature to put cardboard in the oven is around 350 degrees Fahrenheit. This is because the cardboard will not cause a fire at this temperature and instead start to char. If you need to put your pizza in the oven before this time, feel free, but be aware of the consequences.


In conclusion, while cardboard is placed in the oven with pizza, it is not recommended. The cardboard may not withstand the oven’s high temperatures and could potentially catch on fire. Instead, place the cardboard on the bottom of the oven to create a makeshift baking sheet.
