Can you put foil in a toaster oven?

From lining pans for easy cleanup to covering casserole dishes during baking, aluminum foil has many uses. But if you just discovered that you shouldn’t use parchment paper in a toaster oven you’re probably wondering…can you put foil in a toaster oven?

Whether you can put foil in your toaster oven is going to depend on the manufacturer and the type of oven you’re using. 

Here’s what we know for sure: Never cover the crumb tray or the walls of your toaster oven with foil. It’s a fire hazard and something that all manufacturers advise against.

What about lining pans with foil or covering a dish? 

Most manufacturers direct that caution should be used when covering pans and dishes with metal foil.

If the foil is not fitted securely to the pan it can come in contact with the oven’s heating elements (or walls) and cause overheating and an increased risk of fire. 

How can I find the manufacturer’s recommendations for my toaster oven? 

The best way to find out if you can use tin foil in your specific toaster oven is to check your owner’s manual or the manufacturer’s website. 

Toaster Oven Essential - The Manual

Each manufacturer has different instructions for the use of foil in their toaster ovens. And sometimes those directions vary across the models they offer.

The manuals for the Ninja Foodi Ovens are a great example of this. 

  • The manual for the Ninja Foodi XL Pro Air Oven (DT200 Series) gives direction to “Line the sheet pan with aluminum foil…”
  • While the manual for the Ninja Foodi Digital Air Fry Oven (SP100 Series) says to “Never place aluminum foil on top of the sheet pan or broil pan.”

The foil instructions are different because the ovens and the pans are different. This example is just one of the reasons why you should get your answer directly from the manufacturer. 

I know it’s easier to crowdsource info on Facebook or do a quick Google search. But the answer you get from those sources might not be accurate for your oven.

What if I can’t find the manual?

The good news is that most major manufacturers have their manuals available online. They’re usually located under the Support or FAQ sections. 


Cuisinart has a Manuals Page on its website. Depending on the type of oven you have you’ll want to look under the Airfryers category or the Toaster Oven Broilers category

Alternatives To Using Foil In A Toaster Oven

We’re currently working to eliminate the use of foil in our household and have found some pretty good alternatives.

For baked goods like a small batch of cookies, we lightly oil the pan or line it with a small silicone baking mat.

To cook items that call for covering, we use a baking dish with a (non-glass) lid or a small dutch oven. If you go this route, make sure the cover is not airtight as that can lead to other issues.

My favorite quick-fix is super cheap and easy. I just grab our pizza pan or a flat toaster oven cookie sheet and place it over the baking dish.

I used this method to cover a batch of toaster oven potatoes au gratin. It works great and doesn’t create any extra trash.

Happy Cooking!

  1. I’m a bit hesitant about foil. I haven’t had my mini oven for very long. So I only use it for bought ready meals that are in foil so there’s no danger of it falling off or out.

  2. I am new to toaster ovens. When you bake cookies, can you spray the pan with a cooking spray to avoid sticking.

    1. Hi Tina!

      I can’t speak for ALL toaster ovens but we haven’t had any problems with it.

      As an aside, cooking spray is not great for the pan and over time can leave a sticky hard to remove residue. That said, I still spray my pans on occasion 🙂

    1. Hi Ruth,

      The owners manual that came with our Breville Smart Oven Pro (BOV845BSS) has a large warning under the Care, Cleaning & Storage section regarding the quartz heating elements.

      They say to “Use extreme caution when cleaning the quartz heating elements. Allow the oven to cool completely, then gently rub a soft, damp sponge or cloth along the length of the heating element. Do not use any type of cleanser or cleaning agent.”

      You’ll want to refer to your own manual for more specific instructions as it may be different for each model of oven.

  3. I just received a convection,toaster oven with air fryer and was so interested in all the comments. One other question I have is what about those disposable foil trays or muffin pans ? Can they be used in these ovens safely? I haven’t used mine yet because it;s a new kitchen and I don’t want any tragedies. Thanks.

    1. Hi Angela,

      Congrats on your new toaster oven!

      I checked the website for a popular foil tray maker and didn’t see anything either way.

      So I’d say that’s a great question for the manufacturer of your toaster oven, especially if their manual has any specific directions regarding the use of foil. If you need help finding their contact info shoot me an email and I’ll help you get it.

      It’s good to be cautious but don’t let that get in the way of having fun cooking with your new kitchen toy. The metal pan that came with the oven is always a good pan to start with 🙂

    2. I don’t know if you found anything I’m new at it also, someone gave me pot pie I hurt my back so it’s easier to get to toaster oven. I looked this up.
      Instructions: Preheat oven to 400 degrees. … Place pie on cookie sheet or toaster oven baking tray. Bake in center of conventional oven 30 to 33 minutes or toaster oven 30 to 35 minutes until golden brown.Aug 12, 2015

  4. I just hate washing dishes so I use foil as a sort of tray, rather than something that needs to be washed. I use a piece of foil that is wider and longer than the inside of the oven, then fold the edges of the foil several times to give it strength and make it fit into the space. Great for roasting/cooking anything that does NOT have a sauce or any kind of liquid. Cooking fresh or frozen fish is a great application of the idea.

    1. This is such a great tip, Patricia! Super useful if you’re cooking in a camper, cabin, dorm, or anywhere it might be hard to store a lot of pans or difficult to wash dishes. Thank you for taking the time to share directions and meal ideas, I’m sure you’ve helped a lot of people 🙂
