1. Preheat your air fryer: Set the temperature to 180°C (356°F). This ensures that your chicken rings will start cooking at the right temperature for optimal crispiness.

2. Prepare the basket: Lightly spray the air fryer basket with cooking spray. This prevents the chicken rings from sticking and helps achieve a golden, crispy finish.

3. Arrange the rings: Place the frozen White Castle Chicken Rings in a single layer in the basket. Avoid overcrowding to ensure even cooking.

4. Start cooking: Cook for about 7 minutes. This initial cook time starts the crisping process.

5. Flip the rings: Using tongs, carefully flip each chicken ring. This ensures that both sides get evenly cooked and crispy.

6. Continue cooking: After flipping, cook for an additional 5 to 7 minutes. Check the rings at the 5-minute mark; if they need more crispiness, give them a couple more minutes.

7. Check doneness: Ensure the chicken rings are golden brown and crispy to your liking. If necessary, you can cook them for an additional minute or two.
