An air fryer is basically a small, fast convection oven, and the moment that clicks, everything else about using one gets easy. It does not deep-fry – it blasts hot air around food so the outside crisps while the inside cooks. This guide takes you from unboxing to confident everyday cooking: the first-use steps, what the settings really mean, how to get properly crispy results, the foods that shine and the ones to skip, and the nine mistakes that trip up almost every beginner. Written for August 2026 and US temperatures.
How we assess: this guide is based on manufacturer documentation, official instructions, and verified owner reports.
How do you use an air fryer for the first time? Wash the basket, run it empty at 400°F for 5 minutes to clear factory residue, then cook food in a single layer with a light mist of oil. Preheat 2-3 minutes, shake or flip halfway, and start with less time than a recipe says – air fryers run hot and fast.
First-use setup
Before its first meal, wash the basket and tray in warm soapy water and dry them. Then run the empty air fryer at around 400°F for five minutes in a ventilated kitchen. New units often give off a faint plastic or oil smell from factory coatings, and this quick burn-off clears it so your first batch does not taste of it. Once it cools, you are ready to cook – no seasoning or special prep needed.
The two settings that actually matter
Strip away the presets and every air fryer comes down to temperature and time. The fry or chicken buttons are just shortcuts to a preset pair of those two values, and you can always override them. A reliable habit: take any oven recipe, drop the temperature by about 25°F, and cut the time by roughly 20 percent, because the moving hot air cooks faster and closer to the food. Check a couple of minutes early the first time you make anything until you learn how your specific model behaves.
Using oil the right way
You mist, you do not pour. A light spray or a teaspoon of oil tossed through the food is enough to brown it and stop sticking; naturally fatty foods like sausages, bacon, and chicken thighs need none at all. Use a refillable oil mister or a brush rather than aerosol non-stick sprays – the propellants and additives in aerosols pit and peel the basket coating over months of use, which is one of the most common reasons a basket wears out early.
Loading the basket for real crispiness
This is the rule that separates crisp from soggy. Because air fryers cook with circulating hot air, every piece needs space around it. Pile food up and the pieces in the middle steam pale while the edges brown. Cook in a single layer, and if you have a lot, run two batches – it is faster than it sounds and the difference in results is dramatic. Shake the basket or flip the food about halfway through so both sides face the heat.
Quick settings cheat-sheet
Keep this nearby for your first few weeks. It covers the situations beginners hit most often.
| Setting / step | What to do | Why it matters |
|---|---|---|
| First use | Run empty at 400°F for 5 min | Burns off factory residue and smell |
| Temperature | 375-400°F for most foods | Crisps without drying or burning |
| Oil | Light mist or 1 tsp, tossed | Browns food; too much makes it greasy |
| Loading | Single layer, space between pieces | Hot air must reach every side |
| Halfway | Shake basket or flip food | Even browning on both sides |
| From an oven recipe | -25°F and about -20% time | Air fryers cook hotter and faster |
The 9 mistakes new owners make
- Overcrowding the basket – the number-one cause of soggy food.
- Skipping the shake or flip halfway, so one side stays pale.
- Using aerosol cooking spray, which ruins the non-stick coating.
- Cooking wet-battered food – the batter drips off before it sets.
- Putting loose parchment in during preheat, which can blow into the element.
- Not preheating foods that need a crisp start, like frozen or breaded items.
- Trusting recipe times blindly instead of checking early.
- Forgetting to clean after each use, which causes smoke next time.
- Blocking the airflow holes with foil or oversized food.
Foods that shine – and ones to skip
Air fryers are brilliant at anything that wants a crisp exterior: fries, wings, roasted vegetables, breaded cutlets, bacon, reheated takeaway, and salmon. They are poor at wet batters that drip, loose leafy greens and light herbs that blow around, plain melting cheese, and very large roasts that block the air. A simple test: if the food would do well in a hot fan oven, the air fryer will usually do it faster and crisper.
Cleaning and everyday care
Let the unit cool, then wash the basket and tray with warm soapy water; many are dishwasher-safe if the manual says so. Wipe the interior and the exposed heating element with a damp cloth to remove grease that would otherwise smoke on the next cook. A two-minute clean after each use protects the coating and keeps the kitchen smoke-free. For a full routine see our air fryer cleaning guide, and for exact times see our cooking-times chart.
- Run it empty at 400°F for 5 minutes before first use.
- Convert oven recipes: -25°F and about 20% less time.
- Cook in a single layer and shake or flip halfway.
- Use a light mist of oil, never aerosol spray.
- Clean after every use to prevent smoke and protect the coating.
FAQ
Do you need to preheat an air fryer?
A 2-3 minute preheat helps frozen and breaded foods crisp and gives meat a better sear. Fresh vegetables and slow items do not need it. If your manual says preheating is unnecessary, a short one still rarely hurts.
Why is my air fryer food not crispy?
Almost always overcrowding or too little oil. Air fryers crisp by circulating hot air, so food must sit in a single layer with space around it. A light oil mist and a shake halfway through fixes most soggy results.
Can you put foil or parchment in an air fryer?
Yes, with care. Weigh foil or perforated parchment down with food so it cannot lift into the element, and never block the basket airflow holes. Only add parchment once food is in – an empty sheet during preheat is a fire risk.
Do you need oil in an air fryer?
Only a little – a light spray or teaspoon to brown and stop sticking. Fatty foods like chicken thighs and bacon need none. Skip aerosol non-stick sprays, which damage the coating; use a refillable oil mister instead.
What foods should you avoid in an air fryer?
Wet batters (they drip before they set), loose leafy greens and light herbs (they blow around), plain melting cheese, and very large roasts that block airflow. Almost everything else works well.
How do you clean an air fryer after use?
Let it cool, wash the basket and tray in warm soapy water or the dishwasher if labelled safe, and wipe the interior and heating element with a damp cloth. Cleaning after each use prevents smoke and stuck-on residue.
Is an air fryer just a small convection oven?
Essentially, yes. It circulates hot air around food with a fan to crisp the outside quickly. Understanding that one idea explains why single-layer loading, a little oil, and a mid-cook shake are the keys to good results.
Can you cook raw meat in an air fryer?
Yes, and it does it very well – but confirm doneness with a thermometer: 165°F for poultry, 160°F for ground meat, 145°F for whole cuts and fish. Colour alone is not a reliable guide.
