You should preheat the air fryer first, then spray the food directly with oil (or use an oil mister) after preheating but before putting it in, and never spray the basket with aerosol cooking spray as it damages the coating; spray the food when you add it, and again when you flip it halfway through cooking for even crispiness.
It's best to spray or oil the food before adding it to the airfryer.
Spraying the basket or racks with cooking spray. I'll repeat it again: You should never spray your air fryer basket or racks with cooking spray.
5 Common Mistakes to Avoid When Using an Air Fryer
Preheating an air fryer is the same process as preheating an oven: Set the air fryer's temperature to the desired cooking temperature. Leave the basket in so that it can get nice and hot so it will toast or sear your food. Press start or preheat.
Air fryers work by circulating hot air, which originates at the bottom of the fryer. Lining it with foil can constrict the air flow, and your food won't cook properly. If you are going to use aluminum foil in an air fryer, use a small amount at the bottom of the basket, making sure not to cover the food.
For optimal results, preheat the air fryer with an empty basket. This ensures that the cooking chamber reaches the desired temperature uniformly.
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.
You should not be using PAM, FryLight, or any non-stick spray or spray oil that contains lecithin. Lecithin ruins the nonstick coating on the AF.
PAM Air Fryer Spray was specifically designed to reduce residue and build-up on the wire basket or tray, which can lead to wear and tear. With a 450-degree smoke point – higher than a traditional cooking spray - PAM Air Fryer is formulated to withstand the high temperatures used in air frying.
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.
Once I began preheating my air fryer (just five to seven minutes at 400ºF), anything and everything I cooked crisped up so nicely. And, as a bonus, using the air fryer for veggies freed up my oven for other things, like the main protein or dessert. Now, without fail, I use my air fryer every single day.
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.
This grease can end up coating and damaging the fryer, and the excess can create smoke. Bacon's inherent fattiness also negates the air fryer's advantage of low-oil cooking. Consider alternative methods when you're in the mood for crispy bacon.
In just a few minutes, you get perfectly cooked eggs. Whether it's a quick breakfast or a tasty topping for rice bowls or toast, air fryer eggs are fast, fuss-free, and seriously delicious.
Yes, you can put tin foil (aluminum foil) in an air fryer for easier cleanup and to prevent sticking, but you must follow important safety rules: never let it touch the heating element, ensure it's weighed down by food to prevent it from flying around, and avoid using it with acidic foods like tomatoes or citrus to prevent chemical reactions and aluminum leaching. Always check your air fryer's manual and make sure the foil doesn't block the air vents for proper circulation.
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.
The "air fryer rule of 25" is a guideline for converting conventional oven recipes: reduce the oven temperature by 25°F (or 10-20°C) and decrease the cooking time by about 20-25%, checking for doneness earlier. This rule accounts for the air fryer's faster, more intense circulating heat, ensuring food cooks quickly but doesn't burn, though adjustments are always needed based on the specific food and appliance.
Foodies are switching to healthier halogen ovens that are still small enough to sit on a kitchen worktop but have far cheaper running costs. This £29.89 Daewoo model on Amazon costs as little as 11p to run per 20-minute meal as shoppers who 'don't want to spend money on Ninja' pick it.
It's OK to Open the Air Fryer
Occasionally checking in on air fryer foods while they cook is A-OK. Sometimes, recipes call for flipping, shaking, or spraying food with oil mid-cook. Opening the basket is often an essential part of recipes and allows food to be evenly cooked and crisped to perfection.
What happens if you heat water in your air fryer? When our experts in the Good Housekeeping Institute Kitchen Appliances & Innovation Lab first tried this, they heated the water in the air fryer for the amount of time suggested in several viral videos — three minutes — and it only reached 72°F.
