Can You Put the Cardboard in the Oven?

In many houses today, pizza is a favorite Friday night meal for the family. It’s considerably cheap, incredibly convenient, and requires very little cleanup once the eating is done. I don’t think that I even need to mention the awesome part to you guys about pizza, which is that it’s simply tasty and delicious.

While takeout pizza should not require any heating in the oven, the same can’t be said for store-bought pizza. While we typically decide on taking out, pizza purchased at the shop usually costs less and is simply very easy to whip up on a lazy evening.

As you may have probably noticed, pizza brought from the store always comes on a piece of cardboard. Most people, do sometimes use this cardboard to support the pizza as we set it back in the oven, and some even use it to take it out and support the pizza while cutting it more like a pizza cutting board.

Surprisingly, other people do leave their pizza right on the cardboard while it bakes in the oven. Is doing this safe, and is it recommended? In this article, we’ll tell you whether or not you should bake your pizza on the cardboard in the oven.

Is It Safe to Put Cardboard in the Oven?

No. It is actually not safe for you to put cardboard in the oven. Cardboard is combustible, so it can easily catch fire when heated at high temperatures for extended periods.

So, if cardboard shouldn’t be set within the oven, why are there so several claims of individuals doing it safely without having any issue or whatsoever? Well, there’s one good reason for this.

If you happen to set your pizza in the oven directly on a piece of cardboard, and it’s not getting to be in direct contact with a heating element. Because as the temperature rises in the oven, so does the risk of the cardboard getting ignite. However, it is not all of a sudden going to ignite as quickly as putting a part of cardboard on an open flame.

Just have it in mind that for all the claims of individuals putting cardboard safely within the oven, you’ll find their counterparts that had a kitchen all full up with smoke and a few that even started a fire. Again, while it could have turned out just fine for most people, it is still not recommended to set cardboard in your oven.

Even if it had been safe from a fire-safety standpoint, there’s another point to investigate. Many cardboard bases that ship with store-bought pizzas have an anti-grease layer on the outer part of the cardboard. This layer is sure to contain some chemicals that you simply might not want to see leaching into your pizza when it’s heated.

Can You Put Frozen Pizza Cardboard in the Oven?

It somehow works ok, but at the bottom is very soft and potentially soggy. Cardboard will not catch fire or char at normal baking temperatures, but corrugated cardboard is a great insulator and will also prevent the pizza from heating properly. This is more of a problem with frozen pizzas than normal take-and-bake.

If you bake them when thawed, be sure that they are too hard to handle and slide in the oven. If maybe you do thaw them, ensure that you keep them frozen so they can easily slide off the cardboard circle they’re on.

Pizza stones work best for cooking Pizzas. When preheating the oven, preheat the stone on the bottom side rack of the oven. Slide the pizza onto the stone. If you don’t have a stone, you may have to slide the pizza directly to the center rack of your oven to cook.

Only cook one pizza at a time in the oven. If you would like to put fresh garlic or seasonings on top of the pizza before cooking that is also fine.

Some steps to follow when you want to heat your frozen pizza:

  1. Preheat the oven to 430°
  2. Take the pizza out of the box.
  3. Remove the pizza table (the little white plastic table in the middle of your pizza).
  4. Slide pizza only on a rack or stone, (don’t put the cardboard circle within the oven).
  5. You can save the cardboard circle to bring out pizza if you cooked it directly on the rack.
  6. Cook the pizza for 15-18 minutes depending on the number of ingredients on the pizza.
  7. After about 10 minutes of cooking, check every couple of minutes.
  8. When the cheese starts to brown the pizza is done.
  9. If the crust starts to get well-done and the cheese is not brown, put pizza on the top rack and broil for a few minutes to brown the cheese.
  10. If you’re having trouble with the crust burning before you set the pizza within the oven wrap tin foil all way around the pizza crust. Leave the foil on the entire time the pizza is cooking.
  11. If the pizza was cooked directly on the rack, slide the pizza circle cardboard under the pizza to take it out from the rack.
  12. If you used a stone, you may serve the pizza directly from the stone.

Is It Safe to Eat Your Pizza if You Cook it on Cardboard?

You can, but apart from the probability of an open fire, the crust of the pizza will be soggy and probably taste like cardboard. It’s not advisable. The best thing is to put it on a sheet of pan or stone or lay some foil over the rack in your oven. Buh the easiest way is to throw it on a pan that disperses heat better than the cardboard.

What to Use For Cooking in the Oven Instead of Cardboard?

While we have concluded that it is not an honest, idea to cook your pizza directly on the cardboard base that it came with, there are some reasonable options to analyze.

1. Directly on the Rack

A better option that is often advised on the pizza packaging itself is to completely cook your pizza directly on an oven rack. By cooking your pizza on an oven rack, you are allowing for better heating from the underside of it, which should result in a crispier crust.

The major drawback with cooking directly on the oven rack is that you may likely end up with some grease and probably even some toppings falling off into your oven.

2. On a Pizza Stone

As the name implies, a pizza stone gives an excellent surface for cooking your pizzas. Pizza stones are commonly made of ceramic or stone and are usually known for giving a good heating surface and often produce pizzas with a crispy crust.

The crispy crust is produced as a result of the porous surface of the baking stone, which helps in removing some of the moisture from the underside of the pizza dough.

3. On a Pizza Pan

Another reliable option for cooking a pizza is to use a pizza frying pan. There are different styles of pans that are considered pizza pans, and each one of them has its benefits and flaws. Most, but not all, pizza pans are round, which is suitable for a typical store-bought pizza.

If you get a pizza pan with a perforated bottom plate, then your pizza crust should come out crispier, as it’ll get more of the direct heating from the bottom of the oven.

The perforated bottom also lets your pizza to bake more quickly but does allow for some grease to potentially drip through, like when you’re cooking it directly on the oven rack.

4. On a Cookie Sheet

If you don’t want to spend your cash on a pizza stone or pizza pan, you possible have something that may provide similar results, and that is nothing more than a cookie sheet. A cookie sheet delivers a nice flat base surface for your pizza and you should get similar results to a pizza pan.

Just have it in mind that you likely won’t get quite as crispy of a crust with a cookie sheet as you would get with a pizza stone or pizza pan.

5. On Aluminum Foil

when cooking with aluminium foil. However, for most people, foil delivers a simple and readily available choice to use in place of the other methods listed above.

One of the most important benefits of using aluminium foil is that you simply don’t have to do any cleaning to it. After you are done, simply fold it up and throw it away in the waste bin.

Aluminium foil does come with a negative side though, which is that it does not provide much support, mostly when it comes to slicing the pizza after it’s done.

How to Reheat Pizza Without Using the Cardboard?

1. In the Oven

If you have got the time and you are not in a rush, one of the reasonable methods for reheating pizza is to put it back in the oven (using any of the methods mentioned above). The key to reheating the pizza in the oven is to preheat it first, as this will it help to produce a crispier crust.

When reheating the pizza in the oven, you can experiment with temperatures ranging from 350 – 425 F with a baking time of about 5 minutes.

2. On the Grill

If the weather climate is suitable (or you are one among those people that likes to grill in the winter), a fun way for you to reheat your pizza is to place it on the grill. The same basic steps should be followed as mentioned above when reheating in your oven. The outcome should be similar as well.

3. In a Toaster Oven

If you simply do not have an oven or can’t possibly afford one, or you simply don’t wish to bother about heating the one you do have for one or two slices, a more effective option is to reheat your pizza in a toaster oven.

Just like in the oven and grill reheating methods, simply preheat your oven toaster, then put in a slice or two in there for a few minutes, until the cheese starts to melt.

4. On the Stove

Another option for reheating your pizza is to heat it during a skillet on your stove. When using this technique, make sure to warm up that skillet first. Also, ensure that you cover the pan to keep the heat in. Just cook it until the cheese on the pizza starts bubbling.

5. In the Microwave

The microwave should be the final resort, but you can not deny its comfort. When microwaving pizza, the crust may likely end up a bit chewier than you’ll like.

One easy trick to help with this is to put a piece of paper towel below your pizza, which will help to soak up some of the moisture. Furthermore, make sure that you lower the temperature of the microwave to between low and medium.

Your pizza should look fine after that, but don’t expect the outcome to be as good as the other methods mentioned above.


Though it might be tempting in some ways (and even seem convenient) to use your pizza cardboard to cook your pizza, it is simply not safe to put cardboard within the oven. At temperatures above 400 F for prolonged periods, cardboard can potentially catch fire.

Instead of baking or reheating your pizza on cardboard, opt for a safer alternative, such as a pizza stone or even baking directly on the oven rack. Not only can you rest assured that you won’t start a fire, but your pizza is likely to turn out better as well.
