Frequently asked questions
What size air fryer do I need for a family of four?
A 5.5-7L air fryer is usually a good fit for a family of four, giving enough basket space to cook a full meal in one batch rather than needing to cook food in two rounds.
Does a bigger air fryer take longer to heat up?
Larger air fryers generally take a little longer to reach temperature than compact models, but the difference is usually only a minute or two — a worthwhile trade-off if it means cooking everything in a single batch.
Is a drawer-style or oven-style air fryer better for a bigger household?
Oven-style (basket shelf) air fryers tend to offer more usable capacity and multiple racks for a given footprint compared with drawer-style models, which can suit larger households or batch cooking better.
Should I size up if I plan to cook a whole chicken or large joints?
Yes — check the basket dimensions, not just the litre rating, since a whole chicken or large joint needs enough height and width to sit without touching the sides for even cooking.
