5. Cooking Tips
- Preheating: For best results, preheat the air fryer for 3-5 minutes before adding food.
- Shaking: For even cooking and crispiness, shake the baskets halfway through the cooking time, especially for smaller items like fries or nuggets. The air fryer may have a built-in 'Shake' reminder.
- Oil: While air frying requires little to no oil, a small amount of oil (1 tablespoon) can enhance crispiness for some foods.
- Food Placement: Arrange food in a single layer in the basket to allow hot air to circulate effectively. Avoid overcrowding.
- Doneness: Cooking times may vary based on food type, quantity, and desired crispiness. Always check food for doneness.
