1. Preheat the Air Fryer: Preheat your air fryer to 350°F (175°C) for about 5 minutes. This ensures even cooking.

2. Prepare the Spanakopita: While the air fryer is preheating, arrange the frozen spanakopita pieces in a single layer in the air fryer basket. Do not overcrowd to ensure they cook evenly.

3. Spray with Cooking Oil (Optional): Lightly spray the spanakopita with cooking oil. This step is optional but helps achieve a golden, crispy texture.

4. Cook the Spanakpita: Place the basket in the air fryer. Cook for 10-12 minutes, turning the spanakopita halfway through the cooking time to ensure both sides are crispy and golden brown.

5. Check for Doneness: After 10-12 minutes, check the spanakopita. If they are not crispy enough, cook for an additional 2-3 minutes, checking frequently to avoid burning.

6. Remove and Serve: Once cooked to your desired crispiness, use tongs to carefully remove the spanakopita from the air fryer. Let them cool for a few minutes before serving.
