6. Cooking Guide
6.1 General Tips
- Preheating: For best results, preheat the air fryer for 3-5 minutes before adding food.
- Oil Usage: While an air fryer uses significantly less oil, a small amount (1-2 teaspoons) can enhance crispiness and flavor for some foods.
- Shaking/Tossing: For even cooking, especially with smaller items like fries or vegetables, shake or toss the contents of the basket halfway through the cooking time.
- Batch Cooking: Avoid overcrowding the baskets. Cook in smaller batches if necessary to ensure even air circulation and crispiness.
- Food Size: Cut food into uniform pieces for consistent cooking.
6.2 Approximate Cooking Times and Temperatures
The following table provides general guidelines. Actual cooking times may vary based on food quantity, size, and desired crispiness. Always ensure food is cooked to a safe internal temperature.
| Food Item | Temperature | Time | Notes |
|---|---|---|---|
| Frozen Fries (thin) | 180-200°C | 15-25 min | Shake halfway |
| Chicken Wings | 180-200°C | 20-30 min | Flip halfway |
| Vegetables (broccoli, bell peppers) | 160-180°C | 10-18 min | Toss halfway |
| Fish Fillets | 170-190°C | 12-18 min | |
| Baked Goods (muffins, small cakes) | 150-170°C | 15-25 min | Use appropriate bakeware |
