Spraying Oil In An Air Fryer: Safe Or Not?

Air fryers are a popular kitchen appliance, offering a quick, easy, and healthy way to cook food. While air fryers can produce crispy, delicious food without the need for oil, a light coating of oil can help your food crisp up and prevent it from sticking. However, not all oils are suitable for air fryers, and using the wrong one could damage your appliance or affect the taste of your food. So, can you spray oil on food in an air fryer?

Should you spray oil directly onto food before placing it in the air fryer?

Spraying oil directly onto food before placing it in the air fryer is a common practice and can be beneficial in several ways. Firstly, it helps your food crisp up and prevents it from sticking to the air fryer basket. This is especially useful if your air fryer basket is non-stick, as you will need even less oil to achieve the desired results.

However, it is important to note that not all cooking sprays are suitable for use in air fryers. Some cooking sprays may contain additives or oils with lower smoke points, which can affect the taste of your food and cause issues at high temperatures. For example, extra virgin olive oil has a lower smoke point and can burn and affect the flavor of your food. Therefore, it is recommended to use oils with higher smoke points, such as avocado oil, grapeseed oil, or peanut oil. These oils can withstand higher temperatures without breaking down or releasing harmful compounds, which is what you want when air frying.

Additionally, it is advised to avoid using non-stick cooking sprays, such as PAM, as they can damage the lining of the air fryer basket. Instead, opt for a non-aerosol pump-style oil spray that has no propellant, or use a refillable oil sprayer or mister filled with a high smoke point oil. This way, you can control the amount of oil used and ensure an even coating on your food.

Some people also choose to brush oil onto their food or the air fryer basket using a pastry brush, or toss their food with oil in a bowl before placing it in the air fryer. This ensures that the oil is distributed evenly and prevents the need for aerosol sprays, which can be harmful to both your health and the environment.

What are the best oils to use in an air fryer?

When cooking with an air fryer, it's important to consider the smoke point of the oil you're using, as well as the temperature you're cooking at. The smoke point is the temperature at which an oil begins to break down and emit smoke. If the oil reaches its smoke point, it will affect the flavour of your food.

Here's a list of oils with a high smoke point that are suitable for air frying:

• Avocado oil (smoke point: 520-570°F)
• Ghee (clarified butter) (smoke point: 482-485°F)
• Extra light olive oil (smoke point: 465-470°F)
• Sunflower oil (smoke point: 450°F)
• Peanut oil (smoke point: 450°F)
• Grapeseed oil (smoke point: 420-421°F)
• Canola oil (smoke point: 400-450°F)
• Vegetable oil (smoke point: 400°F)
• Refined coconut oil (smoke point: 400°F)

Some oils with a lower smoke point include flaxseed oil, walnut oil, and butter. These are better suited for drizzling over finished dishes or for use in low-temperature cooking.

What are the benefits of using oil in an air fryer?

Using oil in an air fryer has several benefits. Firstly, it can help keep your food moist and prevent it from drying out during the cooking process. This is especially important when cooking fresh meats and vegetables, as these tend to have a higher water content than frozen foods.

Secondly, oil can give your food a nice golden colour, enhancing its appearance and making it more visually appealing. This is particularly desirable for breaded foods, such as chicken cutlets, and roasted vegetables.

Thirdly, oil can help achieve an even browning on both sides of the food. If you need to flip your food during cooking, spraying or brushing it with oil can ensure a consistent colour and texture.

Additionally, oil can be useful when cooking breaded or battered foods, as it helps to prevent dry spots and ensures even browning. It is also essential when cooking sticky foods like salmon with the skin on, as it helps the skin crisp up and prevents it from adhering to the air fryer basket.

Finally, using oil in an air fryer can help reduce the amount of fat and calories in your food compared to deep frying. Air fryers only require a few tablespoons of oil, or sometimes none at all, to achieve crispy results, making it a healthier alternative to traditional frying methods.

What are the downsides of using oil in an air fryer?

While air fryers are marketed as a healthier alternative to deep frying, there are some downsides to using oil in an air fryer.

Firstly, the type of oil used is important. Some oils have lower smoke points than others, and if the oil reaches its smoke point, it will start to smoke and give off a burnt smell that can affect the taste of your food. Low smoke point oils, such as flaxseed oil, walnut oil, and butter, are better suited for drizzling over finished dishes or using in low-temperature cooking. On the other hand, high smoke point oils like avocado oil, peanut oil, sunflower oil, and light olive oil are better for air frying as they have a higher smoke point and a more neutral flavor.

Secondly, the amount of oil used is also a factor. Air fryers only require a fraction of the oil used in deep frying, and too much oil can make your food greasy. It is generally recommended to lightly spray or brush the food with oil before cooking.

Thirdly, the use of non-stick cooking sprays, such as PAM, is not recommended in air fryers as they can damage the non-stick coating of the air fryer basket, making it unsafe for use. Instead, it is suggested to use a non-aerosol pump-style oil spray or a refillable oil sprayer/mister filled with a high smoke point oil.

Finally, while air fryers are convenient for cooking small batches of food, they may not be suitable for larger quantities. The size of the air fryer basket limits the amount of food that can be cooked at once, and cooking in batches can be time-consuming.

In conclusion, while air fryers offer a healthier alternative to deep frying by using less oil, it is important to consider the type and amount of oil used, as well as the potential limitations of the air fryer appliance itself.

How much oil should you use in an air fryer?

Air fryers are a healthy cooking alternative, as they require minimal oil. However, using a small amount of oil in an air fryer can keep your food moist and give it a golden-brown colour. The amount of oil you need to use when air frying is significantly less than what you would use when deep frying or sautéing in a skillet.

When air frying, you can lightly spray your food with oil using a spray bottle. If the food needs to be flipped, you can spray it again on the other side to ensure even colouring. If you're using a non-stick air fryer, you usually don't need to spray the basket. However, this depends on the type of food you're cooking. For example, salmon with skin tends to stick, so for this, you could spray or brush the basket with oil. Alternatively, you can use a silicone liner or perforated parchment paper.

Another option is to toss your food in a bowl with a little oil before putting it in the air fryer. This method works best for cooking fresh meats and vegetables. If you're cooking breaded food, spraying with oil can help achieve even browning and prevent dry spots.

It's important to note that you should not use non-stick cooking spray in an air fryer, as it can damage the lining of the basket. Instead, you can use a non-aerosol pump-style oil spray or a refillable oil sprayer or mister filled with a high smoke-point oil.
