Preheat the air fryer to 400℉
Grab the hash brown patties from the freezer. No need to spray them with oil and do not season them until you are serving.
Once the air fryer is heated add the patties in but do not stack them. Depending on the size of your air fryer basket you may be able to fit more than 3.
Air fry the patties for 4 minutes then carefully flip them for another 4 minutes.
Allow the air fryer hash brown patties to cool a bit and serve them as is, with salt or topped with ketchup.
