Preheat your air fryer to 400°F (200°C) for 3 minutes.
Place frozen hash brown patties in a single layer in the basket.
Spray lightly with oil if desired for extra crisp.
Air fry for 10 minutes, flipping halfway through.
Remove when golden brown and serve immediately.
Notes
Avoid overcrowding the air fryer basket for even crisping. For batches, keep finished patties warm in a 200°F oven. Works with McCain, Great Value, and store brands.
