A lot of people use cardboard to cover their food in the oven. Is that okay?

Good question! The answer is not really. Cardboard will ignite and burn at about 475 degrees Fahrenheit, so don’t put it in the oven.

However, you can line your baking sheets with wax paper or aluminum foil without any problems. The food won’t be able to touch your pan, so it won’t stick, and if there is any dripping, they won’t turn to go on the bottom of your oven either. If you want to use tinfoil for this purpose, that’s fine – just make sure the shiny side is facing down into your baking sheet so that no light reflects off it into your food!

Cardboard is a material typically used in the low-cost packaging and construction industries. It may seem like a viable option for oven insulation, but too many limitations make it efficient, notably the low thermal conductivity and flammability.

When opened and placed inside a kitchen oven, it will typically cause the temperature to rise quickly. The box may catch fire if it is highly flammable or left for a long time inside the oven. In addition, the cardboard may also generate excessive smoke when in contact with heat. It’s harmful to both children and adults in the surrounding area.
