One of the big selling points of an air fryer is using little or no oil — but a tiny bit does help some foods. Here's when to add a little, when to skip it, and how much.
Key takeaways
Q: Do air fryers need oil?
A: Mostly no — a light spray helps lean and fresh foods crisp, but fatty and pre-coated foods need none at all.
Q: How much oil?
A: A light spritz or half-teaspoon brushed on is plenty — never a pool.
When a little oil helps
- Fresh chips and vegetables — a light spray crisps them.
- Lean meat and fish — a brush stops it drying.
- Homemade breaded food — oil turns the crumb golden.
When to skip it
- Fatty foods — bacon, sausages, chicken thighs render their own fat.
- Frozen pre-fried food — chips, nuggets and the like are already coated.
- Anything that pools oil — too much smokes and stops food crisping.
