Preheat Air fryer according to the manufacturer's instructions. Or at 400F for 3 minutes.
Brush the Air fryer basket with oil or use a non aerosol spray. Place hash browns in the Air fryer basket in a single layer. I used 4 patties.
Air fry hash browns for 5 minutes and flip them and cook for another 5 minutes until golden brown.
Serve the crispy hash browns warm. If you end up making more than one batch, you can place all the patties in the Air fryer and warm them up for one or two minutes.
Notes
Store any leftover hash in the fridge, in an airtight container for 3 to 4 days. Don't freeze the cooked hash browns.
To reheat in the Air fryer cook for 2 to 3 minutes at 400F until they are warm.
