No, you should not bake pizza on cardboard. Cardboard is not safe to use in the oven as it can easily catch fire and release toxic fumes when exposed to high heat. Baking pizza on cardboard poses significant fire hazards and health risks.
When cooking pizza in the oven, it's essential to use oven-safe materials like pizza stones, baking sheets, or pizza pans. These items are designed to withstand high temperatures and ensure even cooking without any safety concerns.
If you're looking for an alternative to a traditional pizza stone or pizza pan, you can use a cast iron skillet, a preheated baking sheet, or even an oven-safe ceramic or stoneware dish. Just make sure the material you use is explicitly labeled as oven-safe and can handle the high temperatures required for baking pizza.
Remember, safety is paramount when using the oven, so always use appropriate cookware and follow the manufacturer's instructions. Using cardboard in the oven is dangerous and should be avoided at all costs.
