Frozen stuff works great, everything from fries to eggrolls.

You will start to get an idea how long things take after you have it. Many things now have airfryer instructions, or there are lots of “how to make xxx in an airfryer” articles.

Generic airfryer instructions are usually pretty close for ours, but any given model may have its own cookbook with times for different sorts of things (ours does) and after awhile you’ll get a feel for how to nudge generic instructions to fit your model.

For a very small number of specific kinds of breaded things, I’ll spritz them with cooking spray when they go in to help them get more like they were fried in oil, but that’s really personal preference and I only do it on a couple of things.

Get one with a big enough basket. Things need to be cooked in a single layer. You can pack it pretty full, but single layer is important.
