Do You Need To Preheat An Air Fryer? (How and Why Explained)

Do you need to preheat an air fryer before cooking?

It is important that you do take the time to preheat your air fryer before you use it for a few reasons. It helps with even cooking, it helps you to ensure that you are getting very crispy food, it helps with cooking time by making it faster to get your food done.

How to preheat an air fryer

I’m going to show you exactly how many experienced cooks (both professionally and at home) preheat their air fryers.

Step 1: Read the manual

Reading your manual is a great first step that helps you learn about settings, what buttons are in place and what buttons you need to use to get your air fryer preheated and ready to cook. 

It can also help you get tips for working with the air fryer and making sure that it is going to work for you.

Step 2: Make sure your air fryer is clean

Cleaning your air fryer after each use is going to help you get a better crisp on your food, a better look overall, and is also going to help you to get food that is well cooked. 

Dirty air fryers can lead to food that is burned, it can also lead to strange tastes in your food, and it can lead to build-up on your air fryer that is hard to clean off.

Step 3: Plug it in and power it on

You then need to plug in your air fryer and power it on. When placing your air fryer on the counter, you need to make sure it is set away from the walls and other things on your counter to prevent accidents and to give your air fryer enough space to work.

Step 4: Either manually start the heat or click on the “preheat” button

The next step is to preheat your air fryer. Some fryers do have a preheat button that you can use to get your air fryer heated and ready to go. If your air fryer does not have a preheat button, you can simply turn your fryer on to the temperature that you want and wait for the fryer to come up to temperature. 

Most air fryers are going to have a little green light that will light up when the fryer is up to the right temperature.

Step 5: Select the maximum temperature settings

If you are not using the preheat button, you can set the temp to the max temp to help it get up to the temp faster.

Depending on the model you’re running, most manufacturers will configure your air fryer to cook up to a certain temperature. In the majority of cases, your machine will run up to will likely heat up as high as 250 °C (482 °F).

Step 6: Set a timer

You then need to set a timer so that you can be notified when the air fryer is up and ready to use and ready to air fry your food.

What should you do if you don’t have time and cannot preheat your air fryer?

If you do not have time to preheat your air fryer, you want to make sure you are paying attention to the cooking process and that you are loading your air fryer correctly. 

You want to put food in a flat layer with even spacing and you also need to make sure that you are either flipping or rotating food halfway through cooking to ensure even cooking.

What happens to the food if you don’t preheat your air fryer?

One of the biggest issues with not preheating your air fryer is that your food will have to stay in the fryer longer and you might also end up with food that gets burned before it gets fully cooked or fully browned. 

Preheating helps you get your food done faster and also helps you to get your food crispy faster.

When is it not ok to preheat an air fryer?

If you have food that is not frozen, if you are going to be heating your food for a very short time, or when you are reheating food that has already been cooked, you may not need to preheat the air fryer.

How long do you need to preheat your air fryer?

In most cases, it only takes a minute or two to preheat your air fryer. Most air fryers come up to the heat in a few minutes and are ready to go.

How do you know if the air fryer is preheated?

Most air fryers are going to have some sort of indicator light or temperature readout that is going to help you figure out how hot the air fryer is and help you know that the fryer is ready to go. 

You might also time your fryer when it is heating up and then determine if it is preheated based on how long it takes in most cases to heat up.

Should you preheat your air fryer without the inner basket?

You should not preheat your air fryer without the inner basket in place. You are going to be cooking with your basket in place and preheating without it can affect the overall temperature when you do put your food in and you do try to cook with your basket. 

You want to preheat under circumstances that are as close as possible to what you are going to be using when cooking.

Can you preheat my air fryer with parchment paper inside?

You can use parchment paper in your air fryer when you are preheating but it may affect how long it takes to preheat.

When these cooking devices are active, they have a temperature sensor that tells them when they’ve reached their preheating temperatures. Adding things inside the air fryer will require it take just a little bit longer to get to the right temperature.

The biggest issue with parchment paper seems to come from how the fan will push the paper around causing a lot of noise. With the parchment paper moving frantically inside the fryer, it may take even longer to get to a certain temperature.

If you must, make sure the parchment paper is securely locked down to avoid it from moving. As long as your parchment paper is oven safe, it can be used in your fryer.

Ultimately, it’s best not to leave parchment paper in an air fryer while preheating.

Can you preheat my air fryer with aluminum foil inside?

Similar to parchment paper, it is not advised that you use aluminum foil in your air fryer as it does affect how easily the air can circulate within the fryer.

You can preheat with aluminum foil in place but it may affect how long it takes to heat up and may create an uneven cooking atmosphere.

Do you put food in the air fryer while preheating?

You do not put your food in the air fryer while it is preheating. The purpose of a preheat is to get your air fryer ready to cook so that your food can start cooking immediately and can ultimately cook and finish faster overall.
