Every pizza lover wondered if it was possible to reheat cold pizza in the oven without pulling it out of the box. We all sometimes feel too lazy to follow all the rules adopted in the world of pizza lovers in order to warm it up.

Is it a Good Idea to Heat Pizza box in the Oven?

Well, can you put a pizza box in the oven? Let’s clarify right away. No, you can’t put the box in the oven, when there is high heat. There are many reasons for this. Yes, a pizza box is well suited for its transportation, nothing leaks out of it and it does not tear if it is made with demanded quality. But this does not mean that it can be put in the oven, microwave, toaster oven, air fryer or any kind of oven.

Let’s start with the fact that paper can simply ignite. We all remember chemistry lessons from school, or at least some basics, like the ignition temperature of paper. And cardboard, maybe it will surprise someone, is made of paper.

You will not only have an entirely burnt pizza and its packaging, but you can also ruin the oven or even start a fire that will require immediate extinguishing with a fire extinguisher or even call the firefighters; your neighbors will be extremely unhappy, and you will also be left with a lot of damage.

Is It Safe To Put A Cardboard Pizza Box In The Oven

Fire is a very serious matter and if it is not immediately noticed can lead to a real tragedy, so always handle the oven with care, let alone you should think carefully before allowing the oven to come into contact with flammable objects.

You may be wondering, what if we set the lower temperature? Maybe then everything will work out? No, even if you don’t start a fire, if there are several reasons why heating in a cardboard pizza box is still dangerous under low heat.

What Makes Up Pizza Box

Let’s analyze what the average cardboard pizza box consists of, which you will find in most fast food establishments and pizzerias.

Regular cardboard pizza boxes are made of corrugated cardboard, which consists of several layers of paper pressed and smeared with glue. This makes the box suitable for keeping food warm and prevents the pizza from getting soggy. Detailed information about the pizza box is presented by Food & City. Further, each pizza-selling outlet orders its own design, which is printed in ink.

A wide range of requirements apply to hot pizza boxes, which are also used, for example, for packaging large flat pies:

Thermal resistance

Pizza in a pizzeria is packed hot, and the box should be keeping pizza warm for up to 1-2 hours. This means that the material must be resistant to high temperatures for a sufficiently long time.


The density of the cardboard and the rigidity of the structure must be such that the box does not deform when stacked, since the delivery person, as a rule, delivers several orders at once. In addition, the bottom of the pizza box should not sag under the weight of the pizza, and the side walls and corners that hold the pizza box should also not be deformed.

To increase rigidity, the bottom and the lid are usually made as a single unit, and the lid has additional valves along the entire height of the sides.

Fat resistance

Since such products contain oils and fats, the cardboard pizza box should not be soaked with them throughout its structure. The outer surface of the package must not be oily or greasy. That’s why pizza boxes have anti-grease layer.

When heated in a hot oven, some parts of the box may melt, allowing harmful chemicals from the box and ink to integrate into your food. Of course, this is not a very good idea. You will almost certainly get poisoned and get various degrees of health problems, not to mention the fact that the pizza will taste disgusting.

By itself, the box may not combust under high temperatures. But contact with oil will cause a fire. Almost all types of oils, fat or margarine ignite when in contact with a dry cloth or paper or cardboard. Of course, the desire to enjoy a warm pizza with stretchy cheese is very strong, but it is still better to refrain from the risk of fire.

Low Temperature

Of course, if the box does not contain ink, metal clips, or plastic parts, you can warm the pizza in the box, but to do this, you will have to make sure that there is substantional amount of pizza on the box and the oven temperature is very low. 170 degrees Fahrenheit will be the most right temperature. But keep an eye on your precious pizza, if you see the cheese start bubbling, it means the pizza has warmed up.

Can I store my leftover pizza in its cardboard box?

We highly recommend not storing it in the box. To get started, take a food container, put aluminum foil or a napkin on its bottom, and put the pizza in it (you should also lay a napkin between each piece).
Cover the container with a lid or wrap it with cling film. In this case, the pizza must be completely cooled to room temperature. Before heating, it is worth removing the greens, and lettuce leaves.
Pizza is stored in the refrigerator for no more than 3 days – if you want to increase this period, you can try to freeze it – but we strongly do not recommend doing this! It will come out rubbery and the topping would be tasteless.

Why pizza boxes are square shaped?

There are several reasons for it.
