Spread the frozen hash browns into the base of the air fryer basket. Spray well with the olive oil spray and season with salt and pepper. Add any additional seasonings here as well.
Heat to 370º F and cook for 15 minutes.
After 15 minutes, carefully try to flip the hash browns over. Spray well with oil, and season with salt and pepper.
Cook for an additional 4-5 minutes, until your desired crispiness.
Notes
You may be able to use more hash browns, it depends on the size of your basket.
