Do You Need to Preheat an Air Fryer?

Preheating is not mandatory for every recipe. It mainly improves short cooks that need immediate heat to sear or crisp. For thick foods, bakes in a tin and gentle reheating, starting cold often works well.

When preheating helps

Preheat for 2 to 5 minutes when your appliance manual recommends it and you are cooking:

• breaded or frozen foods that need to crisp quickly;
• a small cut of meat that needs searing;
• bakes that depend on an immediate rise;
• a recipe with a very short cooking time.

Chicken karaage and samosas benefit from a hot basket. Add food only after preheating, using suitable tongs.

When you can skip it

For a whole chicken, gratin or long cook, a few warm-up minutes rarely change the result. Preheating is also usually unnecessary when you reheat food gently.

If a recipe does not say, start without preheating and check near the end. Add two or three minutes next time if needed.

Adjusting the stated cooking time

A recipe’s timing may include preheating or assume the appliance is already hot. Read the method rather than relying only on the total time. If you start cold when a recipe expects a hot basket, add a few minutes and watch browning.

When converting an oven recipe, do not automatically stack every reduction. Use our oven-to-air-fryer guide, then check early because appliances reach their setting at different speeds.

Mistakes to avoid

• Never preheat with an empty parchment sheet; it can be drawn into the heating element.
• Do not heat an empty tin beyond its manufacturer’s guidance.
• Do not extend preheating from habit; it uses energy without improving every dish.
