Searching Google for “air fryer hash brown recipes” brings up over 1 million links plus a bunch of related searches. We haven’t tried hash browns yet but will, one of these days. If it’s half as good with hash browns as it is with tater tots, you’ll be happy. Just remember to reduce the recommended temperature from the recipe or the package by about 15 percent, and shorten the cooking time a bit so you can check the food for doneness before you take it to the full cooking time. We did the tater tots at 380 degrees instead of the 420 called for on the package and they were very crispy, so we might even tweak that temp down a bit more. Most machines have presets for things like fries, chicken wings, etc but better to check the web for recommendations for that fryer model and food type before taking a chance on presets.
Pack the HBs down a bit because the air fryers have a strong fan at the top that can blow small light shreds of food around so remember that if you add things like shredded cheese or breading to whatever you make. It’s basically a small convection oven that uses a basket to hold the food.
Almost anything you can do in an oven can be done in an air fryer, allowing for the much smaller size. Research the subject, read the reviews, get the right size for the number of people you’ll be cooking for ( if you’re not sure,go bigger than you think you need to instead of smaller, you shouldn’t crowd the pieces of food together), and read and follow the suggestions in the links from the meredithlaurence.com site that I posted earlier. The 5 to 8-quart range is probably the best when cooking for more than 2 people.
Experiment with easy and inexpensive food before you try anything elaborate. And remember that these things are pretty big so check the measurements and make sure you have enough room for one, and leave at least 6 inches of open space around the sides and especially the back where the main vent usually is.
Good luck!
