Ask the internet a question and you’ll get all kinds of answers, sometimes varying drastically from one another. One question that caused debate recently was: “Can you put cardboard in the oven?” Now, this is not an everyday thought or something many people have needed to know before – so what is the right answer?
Well, today we are going to dive into it and help clear up any confusion on if things like pizza boxes are safe to use in a hot oven. We will provide common sense tips for anyone brave enough to go against conventional wisdom and explore alternative uses for their kitchen appliance!
What is cardboard made of?
Before we answer the main question, it is important to understand what cardboard is made of and how it reacts in heat.
Most cardboard is a type of paperboard that is made by combining bleached chemical pulp and unbleached mechanical pulp. This material can be recycled easily, making it a great eco-friendly option for packaging materials like cereal boxes and pizza boxes.
How does cardboard work?
Cardboard is usually used as a protective material to keep items safe and secure. It can also act as an insulator, keeping both heat and cold temperatures from transferring easily. This is why it is often used to package food products or transport hot dishes or pizzas.
In the oven, cardboard simply won’t work the same way – it will start to ignite and burn easily.
What are some common uses for cardboard?
Cardboard is a versatile material with many uses. It is often used for packaging, as it provides protection against heat and moisture.
Additionally, cardboard is also great for crafts and DIY projects like making boxes or cutouts.
It can also be used to make furniture such as chairs and tables, as well as decorations and even home decor items like vases or lamps.
Cardboard is also often used in schools, as it can be used to make models and other creative projects.
With its many uses, cardboard is an essential material for everyday life!
Can You Put Cardboard in the Oven?
No, it is not safe to put cardboard in the oven. While cardboard might be useful as a packaging material, using it in the oven can be dangerous and lead to potential fires.
When exposed to high temperatures like those found in an oven, the cardboard will become extremely flammable and potentially start a fire. This is why it is never recommended to put any type of cardboard in the oven – no matter what the situation or purpose of use may be.
Not to mention, the odor of burning cardboard could ruin any food you had planned on cooking!
What Is the Purpose of the Cardboard Base in Pizza Packaging?
The cardboard base you find in pizza boxes is actually there to keep the pizza from sticking and provide a buffer between hot cheese and sauce, and the box itself. This prevents any heat from transferring quickly into the packaging and potentially starting a fire.
While it works great for storing pizzas, it’s never recommended to put cardboard in your oven!
What Happens When Cardboard is Heated?
When cardboard is heated, it will ignite and burn easily. It will not take long for it to catch fire and potentially spread the flames within a few seconds. This is why it is so important to never put cardboard in an oven – even if you are just experimenting!
What Kind of Cardboard Can You Use?
So, if you really want to use cardboard in the oven, what kind of material should you look for?
The best option is to buy fireproof cardboard that’s specifically designed for use in the oven. This type of cardboard will be made from materials like silicone or metal and won’t catch on fire when heated.
However, these types of materials can be quite expensive and might not be available everywhere. If you’re looking for a cheaper option, opt for non-flammable cardboard or paperboard that won’t ignite when exposed to heat.
Why Is Frozen Pizza Packaged with Cardboard?
Frozen pizzas are typically packaged in cardboard because it provides an extra layer of protection against heat and moisture so which provides extra insulation for the frozen pizza. The cardboard prevents the heat from transferring too quickly and melting the cheese or sauce, which could ruin your dinner!
What to Use for Baking in the Oven Instead of Cardboard
When baking in the oven, it is best to use materials that are heat-resistant and non-flammable. Aluminum foil, parchment paper, and silicone baking mats are all good options as they will not catch fire when heated.
These materials can also be used multiple times, making them eco-friendly substitutes for cardboard. Additionally, they provide an extra layer of insulation which helps keep your food from burning.
Directly on the Rack
The best way to cook or reheat a frozen pizza without cardboard is to place it directly on the rack in your oven. This will allow the pizza to bake evenly, as the heat will be able to circulate around the entire pizza.
In a Foil Pan
Another option is to use a foil pan when cooking or reheating a frozen pizza. Just place the pizza in the pan and then place it on the oven rack. The foil will protect the pizza from burning, while still allowing it to bake evenly.
In an Oven-Safe Dish
If you don’t have a foil pan, another option is to use an oven-safe dish when cooking or reheating your pizza. Just make sure to line the dish with non-stick parchment paper or aluminum foil before placing the pizza. This will keep the pizza from sticking to the dish and also prevent it from burning.
On a Pizza Stone
If you have a pizza stone, this can also be used when reheating or cooking frozen pizza. It will work similarly to an oven-safe dish and help the pizza cook evenly without burning. Make sure to use non-stick parchment paper or aluminum foil to prevent sticking. Just preheat the stone in the oven before placing the pizza on top and then bake it until it is hot and crispy!
On a Baking Sheet
The last option is to use a baking sheet when reheating or cooking frozen pizza. Just make sure to place some non-stick parchment paper or aluminum foil on the sheet before placing the pizza on it. This will prevent sticking and help your frozen pizza bake up perfectly!
Discover How to Prepare or Reheat Frozen Pizza: No Cardboard Necessary!
No matter how you choose to cook your pizza – cardboard or not – if you have too much left, it’s still easy to warm up the extra slices without using any cardboard.
Using the Microwave
If you’re short on time and don’t want to wait for your oven to preheat, you can use the microwave to reheat your pizza. Just place the slice of pizza on a plate and cover it with a damp paper towel before putting it in the microwave. Heat it up for 30-second intervals until it is hot and crispy!
Using the Stove
If you don’t have access to a microwave, you can also reheat your pizza on the stove. Just place a non-stick pan over medium heat and add some oil before placing the slice of pizza in it. Cover the pan with a lid and let it cook until it is hot and crispy!
Using the Skillet
You can also reheat pizza slices in a skillet or on an open flame. Just heat some oil or butter in the skillet, then place the slice of pizza on the skillet and let it warm up for about a minute before flipping it over to cook the other side. Make sure to watch it carefully so that it doesn’t burn!
Using the Oven
You can also reheat pizza slices in the oven. Just preheat your oven to 350°F (175°C) and place the slice of pizza on a baking sheet lined with parchment paper or aluminum foil before placing it in the oven. Bake for 10-15 minutes until heated through.

Using the Toaster Oven
For those of you who are not blessed with an oven, a toaster oven is the ideal way to conveniently reheat your pizza. To make sure you get the same way with oven methods as if it was freshly made, reheat your pizza in a preheated toaster oven! Put one or two slices inside and wait until the cheese starts melting. Then enjoy that hot slice of deliciousness without ever needing to turn on your regular oven.
Using the grill
Grilling pizza may sound strange, but it’s actually a great way to get that perfect, crispy crust. Preheat your grill to medium-high and lightly oil the grates. Then place your slice of pizza on the grates and close the lid. Cook for about 5 minutes or until the cheese has melted and the crust is golden brown.
