Can You Put A Pizza Box In The Oven?

A normal pizza box consists of paper or cardboard, which is bulky enough to hold the 6 to 12 pizza slices and also curb the spilling of cheese and oil. It is normally dependable, but is this pizza box strong enough for a hot oven? Can you put a pizza box in the oven? 

No, you cannot put your pizza box into the oven. This is because the greatest temperature a pizza box can withstand without setting itself on fire is 400°F.

Anything bigger than this will trigger your oven, and you’ll need the aid of firefighters. The whole box, comprising the pizza, would catch fire and influence a lot of damage.

What Makes Up A Pizza Box?

A typical pizza box is formed with corrugated cardboard, which is consisted of three sheets of impressed boards attached together.

They are formulated to incubate heat and also to work out the soggy difficulty with holes for a steady flow of air in and out of the box, lessening the likelihood of contamination.

The box is then issued with inks and diagrams. 

The square box is formulated for simple transportation as humans are more likely to move square boxes effortlessly than circle objects.

Is it safe to put the entire box into an oven?

The fact that it matches doesn’t imply that it should be good enough. 

A pizza box contains an anti-grease pane that is closest to the pizza, and this layer is easily disintegrated upon heating.

These chemicals will then see themselves in your food, which may then result in health problems. The arts and ink chemicals may also dissolve when heated, which will sponge itself into your pizza, distorting your food taste and damaging your pizza.

Can Pizza Cardboard Combust?

The pizza cardboard doesn’t catch fire when positioned under great heat. The burst is influenced by animal oil or vegetable oil, that there is carbon in it.

Oils like cooking oil, soybean oil, and margarine are set on fire when they come in touch with rags, paper, or cardboard.

This is another justification for resisting heating pizza boxes in the oven even at specific low temperatures, as the oils in the pizza can result in combustion. 

But, you might ask, what if you fix it to a lower temperature? Is it still careful to do so? It is not stable to do so as some minute actions are happening that may be hazardous to your health.

Let’s discuss that in detail.

Is it Safe to Heat a Pizza Box Under Low Temperatures?

The cautious temperature is anything under 400°F as this temperature is good enough for the cardboard, but this is not totally good for the inks and diagrams on it.

Ensure that the cardboard comprises no metal pins or plastic components.

Preheat your oven to a point varying from 240°F-350°F for 5 to 10 minutes. Once it’s big enough, lower the temperature to around 200°F and place the pizza box enclosing the pizza.

Ensure you remain with it as you may have to heighten or reduce the temperature at certain times.

Put the box in there for 10 to 15 minutes and occasionally open the pizza to inspect the surface. If the cheese gets bubbly, this indicates that it is heating properly. 

Take it out when the edges start browning up, and enjoy.

This technique is not normally safe as some chemicals might have dripped through into your pizza, but if you must utilize the cardboard method, this above-discussed direction is the best.

NOTE! Make sure there is a considerable proportion of pizza in the cardboard, or else the cardboard will catch fire easily.

Can You Put Cardboard Wrapped in Foil in the Oven?

This is also comparable to placing the empty cardboard inside the oven. 

If you think that draping the aluminum foil around the cardboard will dissuade burning, then you are mistaken!

The aluminum is also restrained to heat permeability. 

This is even more hazardous than placing the cardboard singly. At a great temperature, the cardboard will smoke up and result in a fiery inferno.

But then again, frozen pizzas come with cardboard, which should make it safe right?

Not quite.

Pizza cardboard is far distinct from ordinary cardboard because they are intertwined with chemicals. Your frozen pizza cardboard includes drawings made with ink and other chemicals.

The significance of the cardboard is for packaging motives and to deter the smashing of the pizza when it starts freezing. 

The cardboard is also utilized for changing pizza positions from and off the cooking shelf. 

Can You Put A Pizza Box In The Oven?

No, you should not put a pizza box in the oven. Pizza boxes are typically made from cardboard, and cardboard is not meant to be heated in an oven. When exposed to high temperatures, cardboard can easily catch fire or release harmful chemicals and fumes.

If you want to reheat leftover pizza, it’s best to remove the pizza from the box and place it directly on a baking sheet or oven-safe dish.

Why is it Not Recommended to Put a Pizza Box in The Oven?

Four major reasons. We’ll go through them briefly. Let’s go!

Fire Hazard: There is a huge likelihood that the pizza cardboard will get set on fire because of the different materials like metals and plastics or forgetfulness, as many folks are not cautious enough. This can bring in damages and destruction.

Irregular Heating: Since the pizza is contained in a box, there is a high probability of overcooking or undercooking the pizza. The box renders you unable to observe the cooking operation, and you may come out with a burnt pizza.

Chemicals: The chemicals included in the box may dissolve and drip into your pizza. These chemicals may contain the inks utilized for layouts or the thin chemicals within the box. Constant ingestion of these chemicals can lead to long terminal disorders like cancer.

Alteration in Food Taste: The cardboard, inks, and chemicals that trickled into your pizza can result in a shift in taste, as they start to taste metallic rather than the organic pizza taste.

Other Alternatives to Use When Heating Your Pizza

There are several cardboard variations that are good enough for heating in the oven. We’ll be discussing just two today. Let’s go!

1. Aluminum Foil

Preheat the oven to 400°F. 

After taking out your pizza from the box, put a sheet of aluminum foil on it and carefully place the pizza cuts inside, creating a substantial proportion of space in between.

Put it in the oven rack and heat it. 

Aluminum foil is better than cardboard as it is not combustible, no matter the condition the oven is set to.

The advantage that the aluminum foil has is that it is effortlessly available and far economical, but its downside is it could dry up your pizza, but that doesn’t imply the taste will be distinct because of a slight dryness.

2. Pizza Stone

Pizza stones are varied from baking stones, and they are smooth pieces of stones or ceramic that assimilate heat and immediately transmit them evenly onto the cold pizza. 

Pizza stones are far more adequate than cardboard or aluminum foils.

They are better to use and can be reused many times related to the foil. Since they are created with stones or ceramics, they are inflammable. 

The pizza stone employs less heat than the aluminum foil. It takes a temperature of 200°F to 250°F and a time varying from 10 to 20 minutes.

Because of the porosity of pizza stones, your pizza is warmed up evenly, leaving a pizza that is hot enough and soggy-free. The pizza stone conserves heat for a lengthy period, which is why it is recommended to leave your pizza on the stone.

The disadvantage of the stone is it takes a bit of time to heat up, and it is more costly to obtain, unlike the far more inexpensive aluminum foil. 

It is also more likely to crack, particularly on pizza stones made with ceramics and stone. A lot of folks do not have time for such, which is the reason for the choice of the aluminum process.

There are other cooking modes you can utilize in heating your pizza apart from the oven, and they are the skillet, the toaster oven, the microwave, and the air fryer.
