Is it Safe To Use Aluminum Foil in the Toaster Oven?

I had a friend ask me if they could put foil in their toaster. I told them that was silly; you put food in a toaster. I knew what they were talking about but couldn’t pass up the opportunity to make this terrible joke. 

In all seriousness, it is an important question: Is it safe to put aluminum foil in a toaster? While the answer is yes, you must ensure that the foil does not touch any metal or heating element. Provided you avoid those two things, you can use foil.

Below, we will address some additional ways to keep your toaster oven safe. We will also talk about some alternatives to aluminum foil in toaster ovens. 

What You Need To Know About Foil in Toaster Ovens

To keep your toaster oven safe, it’s essential to be aware of two critical things. 

Thing One: The Size of Your Oven

The first thing to be aware of is the size and location of parts of your toaster oven. Because they are much smaller than conventional ovens, it’s easy to touch unwanted edges.

When your foil touches metal or comes in contact with the heating elements, it has a chance to catch fire. There isn’t enough space to put foil in a toaster, meaning you have to pack your foil tightly if you want to consider it. 

Thing Two: What Foil Does With Heat

The second thing to be aware of is how it behaves in an oven. While microwave ovens, conventional ovens, and actual microwaves are different, foil acts much the same in all of them. 

Foil is an excellent reflector of heat and conductor of electricity. That means if you put too much in a toaster oven, that heat will reflect outward. This may cause your toaster oven to overheat, causing permanent damage to the internal components. 

Things You Should Not Do With Foil in a Toaster Oven

  • Cover the crumb tray with foil
  • Wrap the food entirely in foil 
  • Leave any loose bits of foil 
  • Allow foil to touch any parts (wire rack, sides, tops, etc. ) 
  • Put large food inside covered with aluminum foil 

Whether your foil is regular or heavy-duty, putting foil in a toaster oven isn’t a great idea. If possible, limit the use of metal foil to traditional ranges. 

You might also consider some alternatives to aluminum foil. However, parchment paper is not one of them. Do not use parchment paper in your toaster oven. 

Alternatives To Aluminum Foil in Toaster Ovens

Non-Aluminum Cookware

All aluminum cookware has some potential to interact poorly with toaster ovens. As a result, you should keep baking sheets and other materials inside stainless steel.

For example, this stainless steel bakeware set includes various sizes for cooking deserts. Something like that would be perfect. 

If you want some with lids, avoid Pyrex lids. Those won’t survive when coming into contact with heating elements.  

For replacement covers, this is likely your best bet:

Toaster Oven Silicone Baking Mats

Silicone baking mats don’t have the same issue as aluminum foil. Instead, they are perfect for covering food to keep the baking inside. 

Silicone baking mats are typically heat resistant. They also automatically make any surface nonstick, which makes them suitable for covering linings. 

While you still shouldn’t replace the crumb tray, they can operate as coverings. 

Lower Heat

Because toaster ovens are already pretty small and have lower temperature requirements, lower heat is another alternative. Aluminum foil is meant to protect your food from browning too early, allowing the insides to cook more evenly. 

However, some toaster ovens are known to go as low as 150 degrees Fahrenheit. So next time you think you need a cover, try reducing the heat and giving your dish time. 

A Conventional Oven 

If you have something that needs a foil, you might consider replacing the cooking device. Conventional ovens have more space, reducing the chances of any potential exposure. 

Of course, this situation might not be a problem if you have a giant toaster oven. Some people can cut down the aluminum foil to make direct contact with heated elements or electric coils. 

Final Thoughts – Yay or Nay to Aluminum Foil in Toaster Ovens? 

In small toaster ovens, the answer is no. There’s too much risk for you to place anything in a toaster oven comfortably. If your toaster oven is large enough to ensure that the aluminum foil will be safe, cut it down to a bare minimum size before use.

If there’s even a slight chance of the aluminum foil touching something else, don’t do it. 

If you want to toast something using regular ovens, here’s a guide on how to do that. Thanks for reading!
