5 beginner mistakes to avoid

1. Overcrowding the basket. The single most common beginner mistake. Every extra piece you add past a single layer blocks airflow for other pieces. Two batches of perfectly crispy fries beats one batch of steamed, limp fries every time.

2. Skipping preheat. Adding food to a cold air fryer means the first few minutes are spent heating the chamber, not cooking the food. Surface moisture escapes as steam rather than being quickly evaporated. The result is less crispiness and longer cook times.

3. Not patting food dry. This applies especially to fresh vegetables, marinated proteins, and anything that's been stored in liquid. Even a light coating of moisture significantly delays the browning process.

4. Too much oil. You need far less oil than you're probably used to — half a teaspoon to one teaspoon is enough for most foods. Too much oil produces greasy results and can cause the basket to smoke. Also: avoid aerosol cooking sprays like PAM — the propellants can damage non-stick coatings over time. Use a small bottle of oil and apply by hand or with a brush.

5. Never cleaning the basket. Leftover fat and crumbs in the basket burn during subsequent cooks and cause smoke and off-flavours. Wash the basket after every use. Most are dishwasher-safe, but check your manual — the coating degrades faster in harsh dishwasher cycles.

Temperature reference for common beginners

Until you build intuition, these are reliable starting points:

For meat, always confirm doneness with a thermometer: chicken to 74°C (165°F), pork to 63°C (145°F), beef to your preference.
