Preheat your air fryer to 375°F (190°C).

Roll out the puff pastry sheet on a lightly floured surface into a rectangle.

Spread the ranch dressing evenly over the entire surface of the puff pastry.

Lay the ham slices evenly over the ranch dressing, covering the entire surface.

Sprinkle the shredded cheddar cheese over the ham.

Sprinkle the garlic powder, onion powder, dried parsley flakes, and black pepper evenly over the cheese.

Starting from one end, tightly roll up the puff pastry sheet, creating a log.

Using a sharp knife, cut the log into 1-inch thick pinwheels.

Lightly grease the air fryer basket with cooking spray.

Place the pinwheels in the air fryer basket, leaving some space between them.

Brush the tops of the pinwheels with the beaten egg to give them a golden brown color when cooked.

Air fry the pinwheels at 375°F (190°C) for about 10-12 minutes or until they are golden brown and crispy.

Once done, remove the pinwheels from the air fryer and let them cool slightly before serving.

Enjoy your delicious Air Fryer Ranch Ham and Cheese Pinwheels as a tasty snack or appetizer!
