Pizza cooks unevenly in the air fryer

Affects quality

Air-fryer pizza cooks unevenly because the element sits just above a small basket: fit, airflow underneath and turning matter more than the setting.

Applies to: homemade pizza, topped and ready to bake, bought dough, pizza kit, premade or par-baked base, chilled supermarket pizza, take-and-bake pizza, frozen pizza, takeaway or delivery pizza, leftover pizza

Safety: Some frozen and take-and-bake pizzas are not ready-to-eat and must be cooked through. Use an air fryer only if the pack gives instructions for one, follow them, and make sure the centre is steaming hot throughout. Never leave an air fryer unattended, do not overfill it, and do not use loose paper that could reach the element.

Ask yourself

Does the pizza sit flat in the basket, or does it ride up the sides or overlap another slice?
Is the scorching on the highest points (pepperoni edges, the rim) or on one particular side?
Is there a liner, paper or foil covering the bottom of the basket?
Is the outside dark all over while the middle is still cool?

Likely causes

#1
The pizza is too big for the basket and curls up the sides towards the element
Generally accepted
A basket air fryer has its element directly above the food and very little headroom. Any part of the pizza pushed up the basket wall is centimetres closer to the element than the rest and scorches long before the flat middle is done.
#2
Tall toppings and the rim sit close to the element
Generally accepted
Heat from an element a short distance above falls hardest on whatever is highest; pepperoni edges, a puffy rim and mounded cheese brown first while lower areas lag.
#3
Air is blocked from reaching the underside
Generally accepted
Air fryers rely on hot air moving under and around the food. A liner over the perforations, overlapping slices or a crowded basket leaves the base sitting in its own steam.
#4
One part of the basket runs hotter, and the pizza was not turned
Supported, with regional variation
Fan and element layouts differ between models, and many brown one side or the edge of the basket more strongly; a pizza left in one position shows that pattern.
#5
Temperature too high for the thickness of the pizza
Generally accepted
In a small, fast chamber, a thick or frozen pizza browns outside well before heat reaches its middle; a lower temperature for longer narrows the gap.

Equipment-specific causes

The same symptom has different answers on different equipment. Each branch below states how to tell whether it is yours.

Equipment

Pizza in an air fryerGenerally accepted
How you would know: The scorched areas are where the pizza curled up the basket wall or was folded to fit, while the flat middle is underdone.
The pizza is larger than the basket. Anything pushed up the sides sits much closer to the element than the flat middle, so it scorches before the rest has cooked.
Do now: Turn the temperature down and, if possible, trim or cut the pizza so the pieces lie flat; give the flat middle more time.
Change next time: Use a pizza or slices that fit flat with a gap all round, and cook in batches rather than squeezing one in. For packaged pizza, use the air fryer only if the pack gives instructions for one — some list it only for small personal pizzas.

Rescue it now

Lower the temperature, turn the pizza round, and give the pale or cool part more time; if the base is the problem, finish it for a minute or two in a dry, hot frying pan. Check the middle is hot throughout before eating a packaged pizza

Prevent it next time

Choose a pizza or slice that lies flat in the basket with room around it, cook one at a time, use a liner only if the appliance maker allows it and never one that covers all the perforations, turn halfway, and for packaged pizza use the air fryer only if the pack gives air-fryer instructions
