Yes, you should lightly oil food before air frying for better crisping, browning, and flavor, especially with fresh ingredients, but never pour oil into the air fryer basket; instead, brush or spray a small amount directly onto the food, or toss ingredients in a bowl with oil before cooking. For frozen items already coated in oil (like fries), extra oil isn't usually needed, but you can add a bit for fresh items like potatoes or raw chicken to improve texture.
You don't have to use oil in an air fryer, but you can—and should—for the same reason you use oil in any other type of cooking: to prevent sticking and, more importantly, to help lock in moisture and flavor.
While your Philips Airfryer does not require oil to cook and fry the food, adding oil directly to fresh ingredients when preparing them, such as freshly peeled potatoes or chicken, can create a crispy layer and improve the overall taste of your dish. Note: Never pour oil into the pan of the Airfryer.
The simple science is .... Anything can be cooked without oil in an air fryer. Foods inherently consisting of fats (like meat) won't get dry if oil is not used as it would use its own fat to cook and remain moist.
5 Common Mistakes to Avoid When Using an Air Fryer
People are getting rid of air fryers due to small basket sizes limiting family meals, issues with peeling non-stick coatings, difficulty cleaning, safety concerns like melting components, the perception they're just small ovens, limitations on certain foods (like wet batters), and sometimes switching to cheaper, more efficient appliances like halogen ovens. Many find they outgrow basic models, leading to batch cooking, and eventually replace them with larger or different appliances.
The "Air Fryer 20/20 Rule" is a guideline for converting conventional oven recipes, suggesting you reduce the cooking time by 20% and lower the temperature by 20°C (or about 20°F) to account for the air fryer's faster, more intense cooking. While a good starting point, it's essential to monitor your food and potentially shake or flip it halfway through for even cooking, as air fryer models and foods vary, notes this BBC article.
Air-frying equipment is not known to cause cancer, but the process of air frying does result in the formation of certain compounds, like acrylamide, that are linked to cancer development. Acrylamide is classified as a probable human carcinogen.
Worst oils to use in an air fryer
Unrefined oils, such as extra-virgin olive oil and some coconut oils, have lower smoke points and may not yield the coveted crispiness when used in an air fryer. It's also advised to avoid melted butter, as it has a low smoke point and can burn easily.
The best things to put on the bottom of an air fryer for easy cleanup are perforated parchment paper liners, silicone mats, or aluminum foil, though parchment is most popular for catching drippings while allowing airflow. Always use perforated liners or punch holes in parchment/foil to ensure air circulation for crispiness, weigh them down with food, or use them under the crisper tray/basket to prevent them from flying up and touching the heating element.
Avocado oil and light olive oil shine for their high smoke points, while ghee and peanut oils each add unique flavours and health perks. For those looking to experiment, grapeseed and refined coconut oils bring subtle tones and nutritional benefits.
Other types of olive oil and some vegetable oils smoke at lower temperatures, meaning they will cause food to dry up quickly and prevent them from getting crispy, so in addition to extra light olive oil - avocado, grapeseed, and peanut oil are great for achieving crispy goodness when air frying.
You can't cook foods with wet batter, liquids, or loose items like leafy greens in an air fryer as they make a mess; also avoid rice, pasta, popcorn, and large roasts that need even liquid-based cooking or have too much drippings, as they won't cook properly or will burn the machine. Essentially, anything requiring boiling, stewing, or a significant amount of liquid, or very delicate items that blow around, should be avoided.
Overfilling the Basket or Tray
Overfilling your air fryer basket or tray can result in soggy, unevenly cooked food, just like stuffing a sheet pan full of vegetables leads to steaming instead of roasting. To get the best results, cook your food in smaller batches to allow air to circulate around each piece.
It is safe to cook raw meat in the air fryer if it is fully defrosted, seasoned, and monitored. Some fully cooked foods, including chicken tenders or fries, can be placed frozen in the air fryer. However, with raw meat, it's recommended to thoroughly defrost to allow more even cooking and a tasty final product.
Cooking in the oven and cooking in the air fryer will generally end up with food that has the same nutrient profile since an oven and an air fryer use similar heating techniques. In this case, air-frying would not be considered a healthier alternative to baking your food in an oven.
Air fryers are the ultimate no oil frying pans. You can cook crispy, tasty food without the need to submerge it in sunflower, vegetable, or olive oil. For example, this is how you make air fryer chips with no oil.
