Once fully pre heated, spray the air fryer basket with some oil and place the frozen hash browns in the basket in a single layer. Spray the tops of the hash browns with a little more oil.
Cook at 400F / 200c for 14 minutes, flipping halfway through cooking, til golden brown and crispy.
Notes
Cook the frozen hash browns in a single layer in the air fryer basket. If they are overlapping or piled on top of each other they won't cook evenly.
If you want to cook more hash browns than will comfortably fit in your air fryer, you can keep the cooked ones warm in the oven til ready to serve.
Preheat the air fryer before cooking them. This will ensure that they are extra crispy.
Air fryer models can run slightly differently, so timings may need to be adjusted slightly during cooking.
The oil spray is optional, but does result in crispier hash browns.
Sprinkle over a little seasoning before cooking if you like.
