Getting crisp results from an air fryer

Summary

This pattern is for anyone who uses a countertop air fryer. It describes how to load, time and look after it so hot air can reach every surface and food comes out crisp and cooked through.

Recommendation	Why?
Preheat for 3 to 5 minutes, unless your manual says not to.	Food that goes into a hot basket starts browning straight away instead of steaming.
Cook in a single layer, with gaps between pieces.	An air fryer is a small fan oven. Air needs to move around each piece to crisp it.
Cook in batches rather than overcrowding.	A packed basket steams the food, and the pieces in the middle stay soft.
Shake the basket or turn the food halfway through.	The side facing the element browns faster, and turning evens it out.
Toss fresh food in a teaspoon or two of oil.	A thin coating helps browning and crisping. Frozen pre-fried food usually needs none.
Converting an oven recipe, lower the temperature by about 20 °C and cut the time by about 20%, then check early.	The fan and small chamber cook faster than a conventional oven.
Never put baking paper or foil in without food on top to hold it down, and keep the vents clear.	Loose paper can blow into the element and scorch or catch fire, and blocked vents overheat the unit.

Context

This pattern suits small portions of food that benefit from dry heat: chips, roast vegetables, chicken wings and thighs, fish fillets, frozen snacks and reheating leftovers so they stay crisp.

It does not suit wet batters (they drip off before setting), large roasts that won’t fit with space around them, or big family quantities that need many batches, where the main oven is often quicker overall.

There’s a trade-off between capacity and crispness. Filling the basket feels efficient but gives soggy results. This pattern chooses smaller, well-spaced batches, keeping finished batches warm in a low oven if needed.

Usage

Setting up: stand the air fryer on a heat-resistant, stable surface with space around the vents as the manual describes, away from walls and cupboards. Preheat while you prepare the food.

Cooking: pat fresh food dry, toss with a little oil and seasoning and lay it in one layer. Shake or turn halfway. Check meat and poultry with a thermometer rather than trusting the timer, because small pieces cook quickly on the outside; see Cook by temperature, not time.

Reheating: leftovers crisp up well at around 160 to 180 °C for a few minutes, but they still need to be steaming hot all the way through; see Cooling and storing leftovers.

Cleaning: let the basket cool, then wash it in warm soapy water with a soft sponge. Most baskets have a non-stick coating, so avoid metal utensils and abrasive scourers and don’t use aerosol oil sprays; Making non-stick pans last explains why. Wipe out grease regularly, as built-up fat can smoke.
