Air fryers have gained popularity as a cooking tool, especially for those who are conscious of their diet. One of the claims made about air fryers is that they don’t require any oil to achieve crispy and delicious results. However, it’s important to understand the role of oil in air frying and determine how much oil, if any, should be used. In this article, we will explore the use of oil in air fryers and provide guidance on the amount of oil to use for optimal results.

How Do Air Fryers Cook Food?
Before delving into the use of oil in air fryers, let’s first understand how these appliances cook food. Air fryers function similarly to convection ovens, which use a fan to circulate heat evenly within the cooking cavity. In the case of air fryers, a heating coil located on the top heats the air inside the food basket, while a fan below the basket circulates the hot air, resulting in crispy exteriors and evenly cooked interiors.
Do Air Fryers Use Oil?
Contrary to popular belief, air fryers do not necessarily require oil to achieve the desired crispiness. The Maillard reaction, responsible for the browning and flavor development in cooked food, can occur without the presence of fat. The browning observed at temperatures above 350°F is primarily due to caramelization, which involves the melting of sugars rather than the reaction with fat.
However, while oil is not necessary, it can serve as a flavor enhancer and help retain moisture in the food. Cooking food in a hot environment, such as an air fryer, can cause it to dry out to some extent. Adding a small amount of oil can help prevent dehydration and contribute to the overall taste and texture of the dish.
How Much Oil to Add to an Air Fryer
If you decide to use oil in your air fryer, it’s recommended to use a modest amount. As a general rule of thumb, slightly less oil than you think you’ll need is sufficient. For most dishes, 1 or 2 teaspoons of oil should be adequate. It’s important to note that the oil should be applied directly to the food rather than the food pan to prevent leakage and potential damage to the air fryer’s components.
Best Oils for Air Fryers
When selecting oils for air frying, it’s advisable to choose those with high smoke points. The smoke point refers to the temperature at which the oil starts to smoke and break down, negatively impacting the flavor and quality of the food. Given that air fryers can reach temperatures of 400°F and beyond, oils with high smoke points are preferable. Options such as peanut oil, avocado oil, sesame oil, sunflower oil, and canola oil work well for air frying. Butter and olive oil, although flavorful, have lower smoke points and are best used during the final stages of cooking rather than as an initial oil for air frying.
Nonstick Spray Oil and Air Fryers
While nonstick spray oils are effective in preventing food from sticking to other surfaces, they should not be used directly in air fryers. The interaction between Teflon surfaces and nonstick cooking sprays can lead to the accumulation of hard-to-remove particles over time, potentially damaging the nonstick coating. Instead, if you need to lubricate the air fryer, it’s recommended to apply oil or butter to the exterior of the food or tuck small amounts under the skin of poultry.
Cleaning Greasy Residue from an Air Fryer
When oil is used in an air fryer, it can leave behind a greasy residue. Cleaning the food pan, basket, and base of the air fryer is a relatively simple process. Once the air fryer has cooled down, remove the food basket and pan. Separate the pan from the basket and soak them in warm, soapy water for approximately 10 minutes. Use a soft sponge to scrub the pan and basket, rinse them thoroughly, and allow them to air-dry. To clean the interior and exterior of the air fryer’s base, use a paper towel for the cooled heating coils and a damp microfiber cloth for the remaining surfaces.
Nonstick Accessories for Air Fryers
If you prefer to avoid using oil altogether or want to minimize cleanup, there are alternative nonstick accessories that can be used in air fryers:
- Aluminum foil boat: Create a boat-shaped structure with aluminum foil to hold the food, capturing any juices and preventing them from dripping into the drip pan. This technique can be useful for making gravies or sauces from the accumulated juices.
- Parchment paper: Parchment paper, with its nonstick properties, can be used to prevent food from sticking to the air fryer’s surface. However, it may impede optimal airflow due to blocking the perforated base of the food pan.
- Silicone mat: A silicone mat placed inthe food basket can provide a nonstick surface for cooking. It allows for easy cleanup and helps prevent food from sticking.
Air fryers can produce crispy and delicious results without the need for excessive oil. While oil is not necessary, it can enhance flavor and prevent food from drying out. Adding a small amount of oil directly to the food before air frying is recommended, using oils with high smoke points such as peanut oil, avocado oil, sesame oil, sunflower oil, or canola oil. Nonstick spray oils should be avoided in air fryers to prevent damage to the appliance. Cleaning greasy residue from the air fryer is a straightforward process, and there are nonstick accessories available to reduce or eliminate the need for oil. With proper understanding and practice, air fryers can be a versatile and healthy cooking tool in your kitchen.
