Air fryers are a popular kitchen appliance, known for their ability to cook food quickly and conveniently, producing a crispy texture similar to deep-fried food. While air fryers use hot air to cook food, a small amount of oil is often added to enhance flavour and texture. The type of oil used can significantly impact the cooking experience and the final dish. This is where the concept of a smoke point comes into play. The smoke point of an oil is the temperature at which it begins to break down and smoke, affecting the flavour, quality, and potentially releasing harmful compounds. Therefore, choosing oils with a high smoke point is crucial for air frying at high temperatures without compromising flavour or health benefits.

Avocado oil has a high smoke point and neutral flavour
Avocado oil is a top choice for air frying. It has a very high smoke point, a neutral flavour, and is rich in heart-healthy unsaturated fats.
The smoke point of an oil is the temperature at which it begins to burn and produce smoke. When oil hits its smoke point, it can lose flavour, degrade in quality, and release harmful compounds. For air fryers, choosing oils with a high smoke point (over 200°C) means you can cook at high temperatures without compromising on flavour or health. Avocado oil has a smoke point of around 270°C, making it ideal for air fryers, which cook at high temperatures.
The neutral flavour of avocado oil means it won't change the taste of your food. This makes it a good choice for spicy or strong-flavoured recipes, as it can handle the heat without imparting any unwanted flavours. Avocado oil is also a healthy choice, as it is rich in heart-healthy unsaturated fats.
When using avocado oil in an air fryer, it's important to remember that you only need a small amount. Air fryers require much less oil than traditional frying methods, and a little goes a long way. Simply spray or brush a small amount of oil on the food before cooking to achieve the desired crispy texture.

Light olive oil is ideal for high-temperature cooking
When it comes to air frying, selecting the right oil is about more than just taste. It's about making choices that support both health and flavour. Air fryers cook food using hot air circulated at high speed by a fan, creating a crispy, golden exterior. This means the oil you choose matters: you need options that can handle the heat without losing quality or compromising health benefits.
Light olive oil, also known as refined olive oil, is produced using heat after the first pressing of virgin oil from olives. It has a golden yellow colour and a neutral flavour, as opposed to the deep green colour and distinctive taste of extra virgin olive oil. Because it is refined, light olive oil has a longer shelf life and a higher smoke point than other types of olive oil.
When cooking with an air fryer, it is generally recommended to add 5-30ml of oil. This small amount of oil can be brushed or sprayed onto the food before cooking, or added directly to the basket (taking care not to let it come into contact with any electrical pieces). A light coat of oil will help your food crisp up and keep it from sticking to the basket.

Ghee, or clarified butter, is a great option for Indian and French cuisines
Ghee, or clarified butter, is a fantastic option for Indian and French cuisines when using an air fryer. Ghee is a type of clarified butter that has been simmered to separate the milk solids, giving it a nutty flavour and aroma. It is a traditional ingredient in Indian cooking, used in a variety of dishes from flatbreads to curries, and is an essential component in French cuisine as well.
Ghee is perfect for Indian dishes like roti, naan, biryani, and curries, adding a rich, nutty flavour. In French cuisine, ghee can be used for sautéing, frying, or as a butter substitute in pastries and sauces. The process of clarification also gives ghee a higher smoke point than regular butter, making it ideal for high-heat cooking methods such as air frying.
When selecting ghee for air frying, it is important to note that the smoke point can vary depending on the production method and temperature. Ghee produced at lower temperatures tends to have a milder flavour and a lower smoke point, while higher temperatures result in a stronger flavour and a higher smoke point. Therefore, when choosing ghee for air frying, opt for one produced at a higher temperature to ensure a higher smoke point, which is key when cooking with an air fryer.
The versatility of ghee makes it an excellent choice for a variety of dishes. It can be used as a finishing drizzle on curries, a cooking medium for savoury and sweet dishes, or as a substitute for butter or oil in French pastries and sauces. Ghee is also said to have health benefits, making it a nutritious and flavourful addition to any meal.
When using ghee in an air fryer, it is important to ensure that the temperature is adjusted accordingly. While ghee has a higher smoke point than butter, it can still smoke if the pan is too hot. It is recommended to start with medium-high heat and adjust as needed to avoid smoking. Additionally, using a generous amount of ghee is crucial, especially when cooking breaded items, as it ensures even heat distribution and prevents the ghee from burning.

Peanut oil has a nutty flavour and high smoke point
Peanut oil is a great choice for air frying, especially if you're looking for something with a nutty flavour. Its high smoke point means it can handle the heat of an air fryer without burning, degrading in quality, or releasing harmful compounds.
The smoke point of an oil is the temperature at which it begins to break down and emit smoke. When oil reaches its smoke point, it can lose flavour and negatively impact the taste of your food. It can also be dangerous, as it releases harmful compounds. For this reason, it is important to choose oils with a high smoke point when air frying, as this method of cooking involves high temperatures.
Peanut oil has a smoke point of around 450°F (232°C), which is higher than that of extra virgin olive oil, which has a smoke point of 375°F (190°C). This makes peanut oil better suited for air frying than extra virgin olive oil, which should be reserved for lower-temperature cooking methods such as drizzling on salads or sautéing.
When using peanut oil in an air fryer, it is important to remember that a little goes a long way. Air fryers require much less oil than traditional frying methods, and a small amount of peanut oil will be enough to enhance the flavour and texture of your food.
In addition to its high smoke point, peanut oil also has a pleasant, nutty flavour that can enhance the taste of your air-fried dishes. This makes it a good choice for those who want to add a subtle flavour to their food. However, if you prefer a more neutral flavour, you may want to opt for oils like avocado oil, ghee, or light olive oil.
