To air fry crab rangoons: Lightly spray the air fryer basket with oil to prevent sticking, and preheat the air fryer to 350°F. Arrange the uncooked crab rangoons in a single layer, ensuring there’s space between each one to allow even airflow. Avoid overlapping, as this may hinder proper cooking. You may need to work in batches. Evenly spray a light coat of oil (approximately 1 tablespoon per batch) over the rangoons, or for extra crispiness, brush the exterior of each wonton with oil. Air fry for 6–8 minutes until crispy and golden brown. If needed, add an additional 1–2 minutes to achieve your desired level of crispiness, keeping in mind that cooking times may vary between air fryer models.
