Generously spray or brush the bottom of the air fryer basket with oil. Then, spread the frozen hash browns evenly and use a spatula to divide the potatoes into 4 sections. This will help to evenly brown your hash browns.
Sprinkle with salt, pepper, and onion powder, and then drizzle the top with more oil or spray.
Cook at 400°F for 15 minutes, or until the edges are crisp and golden, and then carefully flip each section. Continue air frying for another 4-5 minutes until crispy.
Fresh hash browns
Cut potatoes into quarters if using a food processor. If you prefer the skin off, do this first.
Use a food processor with the shredding disc attachment or a box grater to shred the potatoes. Place the shredded potatoes in cold water and allow to soak for 10-15 minutes to remove excess starch. This will help them crisp up while cooking.
Transfer to a colander to drain the water. Rinse them very well before transferring the shredded potatoes to paper towels or a clean dish towel to dry them completely. Transfer back to the bowl and season with salt, pepper and onion powder, and toss lightly to combine.
Preheat the air fryer to 400°F. Generously spray or brush the bottom of the air fryer basket with oil and spread the shredded potatoes evenly. Use a spatula to divide the potatoes into 4 sections, and then drizzle the top with more oil or spray.

Notes
Storage: These hash browns can be kept in the fridge in an airtight container for a few days. To reheat them, I like to crisp them up again in the air fryer for a couple of minutes.
