Can You Put Aluminum Foil In The Toaster Oven? – Dwell Hack

When enjoying your sandwich by the lake on a beautiful summer day, and you can’t stop thinking why this sandwich still tastes so fresh and so good—the magic word for this is ‘aluminum foil.’ It works as a barrier; isolates your food from light and oxygen. Oxygen helps oxidize food fat or become rancid; no one wants that to happen to their sandwich.

Just Like that, we use the foil in our day-to-day life to cover our foods. It has various uses, but it can cause accidents if not used properly. After all, you’re playing with metal. Many questions cross our minds about foils, like can you put foil in a toaster oven? Can you put aluminum foil in a toaster oven? Can you put tin foil in a toaster oven?

This article will help you to find out the answer to the burning question in your mind that can you put aluminum foil in the toaster oven?

two side of aluminum foil

If you have noticed, there are two sides to the foil. One side is shiny other is matte colored. People like to make a huge fuss about which side to use. The difference comes during the milling process. Milling is when heat and tension are applied on the Aluminum to stretch out for the desired thickness.

Two layers are used during this process; the dull side appears on the side where the foil gets in contact with another layer, where it does; it remains shiny.

In general, either side is okay. But, in Layman’s term, the shiny object reflects heat. If you put the matte side toward food and the shiny side is kept outside, then the shiny side would reflect more heat than the matte side.

The difference is too little to notice as Aluminum is an excellent heat conductor. Feel free to use either side as you want; It would not make any difference unless your foil is a non-stick foil. In non-stick foils, it is usually imprinted “non-stick side” for user’s convenience.

Is Cooking with Aluminum Foil Safe?

Unlike other elements like Sodium, Iron, Calcium, Aluminum does not take part in bodily functions. It is a non-essential mineral. If somehow they enter our body, they serve no purpose. The body can excrete a certain amount of Aluminum daily, too much exposure might live some of them in the body. Sometimes Aluminum alters the paths of bodily reactions. During the ’70s, in research, a correlation was found between Alzheimer’s disease and Aluminum. A high level of Aluminum was found in the brain of the people who had Alzheimer’s disease.

It is considered to be safe cooking with this foil. It is a very common household product often used for cooking or covering dishes for later use.

As long as you are not exposed to a high dose of Aluminum, you will be safe. Generally, It is not possible to get harmful exposure from aluminum foils only.

Most of the foods contain a very low amount of Aluminum naturally, so it is safe for our health.

Aluminum Foil in a Toaster Oven: The Explanations

Now we come to the ultimate question, can you use aluminum foil in a toaster oven? First, let us get our ideas right. A toaster oven works differently than the microwave oven. It is a box surrounded by heating equipment that uses a lot of energy to toast things. Add to that Aluminum is one of the best heat conductors.

If you put it in the toaster oven and heated enough, Aluminum does what it does best. It keeps absorbing heat as there is no one to pass to. Then in no time, it is doing what every metal does. It creates a spark, it melts. In the worst case, it might get on the flame.

Since it is a metal, and heated metals are likely to create a spark when they contact other metals. It will create a spark if it comes in contact with any other metal in the oven. If you manage to avoid spark, the foil might raise the temperature to a level not designed for the oven. That may cause meltdown and fire.

The foil reacts if it is placed in a microwave oven. The microwaves and electromagnetic fields that it creates will cause electric arcing in the air surrounding the sheet.
