Can You Put Foil in an Air Fryer? Exploring the Do’s and Don’ts

Air fryers have become a popular kitchen appliance for those seeking a healthier alternative to traditional deep frying. Their ability to cook crispy and delicious Food with significantly less oil has made them a staple in many households. However, when it comes to using accessories like aluminum foil in an air fryer, there are often questions and concerns. Can you put foil in an air fryer? Let’s delve into the dos and don’ts of using foil in this versatile kitchen gadget.

Understanding How Air Fryers Work:

Before we discuss the use of foil in air fryers, it’s crucial to understand how these appliances function. Air fryers work by circulating hot air around the Food, cooking it evenly, and producing a crispy outer layer. Unlike traditional deep frying, air fryers achieve this result with the help of a fan and a heating element.

The Do’s:

  1. Lining the Bottom: You can use foil to line the bottom of the air fryer basket. This can make cleaning up easier, as it catches any drips or crumbs that fall during the cooking process. Ensure that the foil is flat and doesn’t obstruct the air circulation, as this could affect the cooking efficiency.
  2. Creating Packets: Foil can be used to make packets for cooking certain foods in an air fryer. For example, if you’re cooking fish or vegetables with a sauce, wrapping them in foil can help keep the flavors sealed and prevent any drips.
  3. Shielding Delicate Foods: When cooking foods that might burn easily on the top, like certain desserts or cheese-topped dishes, you can use a small piece of foil to shield them. Just be sure not to cover the Food completely, as this can hinder air circulation.
  4. Molding Foil Cups: Forming small cups out of foil can be useful for cooking items that might otherwise fall through the air fryer basket. This is handy when preparing smaller ingredients like nuts or seeds.

The Don’ts:

  1. Blocking Airflow: One of the most crucial considerations when using foil in an air fryer is to avoid blocking the air vents. The proper circulation of hot air is essential for achieving the desired crispiness. Never completely wrap the Food in foil, as this will hinder the airflow and result in uneven cooking.
  2. Covering the Food Completely: While it’s acceptable to use foil to shield certain parts of the Food, protecting the entire dish with foil is a big no-no. This will prevent the hot air from reaching the Food, leading to unsatisfactory results.
  3. Using Non-Paper Coated Foil: If you decide to use foil in your air fryer, opt for non-paper-coated varieties. The paper layer on some foils can burn and potentially damage the air fryer or affect the taste of your Food.
  4. Cooking Acidic or Spicy Foods: Avoid using foil for highly acidic or spicy foods, as these can react with the foil and affect the taste of the dish. If you need to cook such items, consider using other air fryer accessories like silicone or parchment paper.

Tips for Using Foil in an Air Fryer:

  1. Poke Holes: If you’re using foil to create a packet for cooking, remember to poke a few holes in it. This allows steam to escape, preventing the Food from becoming soggy.
  2. Use Lightweight Foil: Opt for lightweight foil to ensure that it doesn’t weigh down the Food or obstruct the airflow. Heavy-duty foils can impede the air fryer’s performance.
  3. Experiment with Small Pieces: If you’re unsure about using foil, start with small pieces and observe how it affects the cooking process. This way, you can gauge its impact without risking an entire meal.
  4. Refer to the Air Fryer Manual: Always consult your air fryer’s manual for specific guidelines regarding the use of foil. Manufacturers often provide recommendations to ensure safe and efficient operation.


In conclusion, using foil in an air fryer is possible, but it requires careful consideration of certain do’s and don’ts. While foil can be a helpful tool for specific applications, it’s crucial to avoid hindering the appliance’s airflow, as this can significantly impact the cooking results. By following the guidelines provided by the air fryer’s manual and experimenting cautiously, you can make the most of this versatile kitchen gadget while ensuring safe and delicious meals.
