Short Answer:

To cook multiple frozen items efficiently in an air fryer, avoid overcrowding the basket. Arrange foods in a single layer with space between each piece and cook in batches if necessary.

Shake or flip the items halfway through cooking to ensure even heat distribution and uniform crispiness. Adjust temperature and cooking time according to the size and type of items, using preheating and optional light oil to enhance browning and texture for all pieces.

Detailed Explanation:

Cooking Multiple Frozen Items Efficiently

Avoid Overcrowding
Overcrowding the air fryer basket reduces airflow and leads to uneven cooking. Frozen items placed too closely together may cook inconsistently, with some pieces remaining soft while others become overcooked. Place items in a single layer and leave small gaps between pieces to allow hot air to circulate effectively.

Batch Cooking
For large quantities, cook in batches rather than all at once. Although this may take slightly longer overall, batch cooking ensures that each piece receives sufficient heat and achieves crispiness. Divide frozen items according to size or type to maintain uniform texture and flavor.

Shaking or Flipping Midway
Shaking or flipping the items halfway through cooking redistributes food in the basket, ensuring all sides are exposed to hot air. This step prevents uneven browning, soggy spots, and undercooked centers. It is particularly important for coated or breaded items such as nuggets, fries, or spring rolls.

Temperature and Cooking Time Adjustments
Set the air fryer to the recommended temperature for the type of food, usually 180–200°C (360–400°F) for frozen snacks. Thicker items or larger pieces may need slightly longer cooking times. Adjust cooking times and monitor doneness for even results across all items.

Optional Light Oil Spray
A light spray of oil helps promote even browning and enhances crispiness. Minimal oil is sufficient, as hot air circulation cooks and crisps the surface. Avoid excessive oil, which can create a greasy texture and uneven results.

Preheating the Air Fryer
Preheating for 2–3 minutes ensures the appliance reaches the proper temperature before adding frozen items. This reduces overall cooking time, prevents uneven cooking, and helps all pieces develop a golden, crispy exterior.

Tips for Mixed Items

• Arrange similar-sized items together to ensure uniform cooking.
• Monitor different items with different thicknesses and remove those that finish earlier to prevent overcooking.
• Use visual cues and optional thermometers to confirm doneness for meat or stuffed foods.

Conclusion:

Cooking multiple frozen items efficiently requires proper spacing, batch cooking, shaking or flipping midway, and monitoring temperature and time. Preheating and optional light oil enhance crispiness and browning. Following these steps ensures that all frozen foods, from fries and nuggets to spring rolls and vegetables, cook evenly and maintain optimal texture and flavor.
