As a kitchen enthusiast, aluminum foil is an integral part of your kitchen, no doubt. The main idea has always been to foil it, whether it’s a casserole, salmon, or baking a cake.

These days, most manufacturers are adding ‘how-to videos’ to their Youtube channels or websites, and they may include a few tips on using the aluminum foil.

You can also get the same updated info from the website. For example, on one website, the manufacturer recommends cutting the aluminum foil to fit precisely on the toaster oven pan. You should not leave anything overhanging.

Breville recommends carefully covering food and making sure there is maximum airflow. On the other hand, Oster has a how-to video on how you can safely use aluminum foil. According to Cuisinart, you are free to use the aluminum foil as long as you make sure not to cover the rack and no overhang.

Hamilton Beach tells you that you can use aluminum foil, but you must be careful not to cover the crumb tray or touch the heating elements.

Why the Aluminium Foil and Toaster Oven are not a Great Idea

But why is this so?

So what is the problem with having aluminum foil inside the toaster oven?

One of the reasons why you shouldn’t use aluminum foil is the heat it reflects and conducts. Even though this is the primary goal, the foil may cause overheating inside the oven and become a fire hazard.

The high temperatures may exceed the allowed levels and break or melt some of the components inside the oven. Don’t cover the drip tray with foil, no matter how tempting it may be. Air will not circulate properly, and this can as well cause overheating.

The other risk is from the sparks, which generate when you fail to cut the oil to the pan’s exact size. Some mistakes are unavoidable. It is possible to leave a protruding piece of the aluminum foil and contact the heating elements to produce sparks.

The sparks make contact with the oil on your dish, and before you know it, the oven is a piece of junk. In the worst-case scenario, the sparks generated may cause a big fire that burns down your home.
