Did salmon steak in mine tonight. 11 mins to cook 2 mid sized ones at 180 degrees C, no pre-heating with my model, & they were delicious. I followed a bbc good food recipe.
Sweet potato chips cook nicely in it too, but don’t need as long as oven chips or potato wedges, only about 15 mins at 180 degrees, or they tend to burn on the edges. I suppose each model varies slightly, though, so keep opening the drawer to check progress.
I’ve cooked chicken kebabs in it, too. About 20 mins if memory serves me right. However, as I say, check as you’re cooking, as different makes vary.
I’d recommend the bbc good food air fryer book if you’re looking for one with basic ideas to start you off. (Not advertising, by the way, it’s just that I bought one and think it’s helpful - other books are available, plus you can Google recipes on line, including the good food ones).
Really, though, they are a small oven, so treat them as you would your oven, just bear in mind that it’s unlikely that you can do a large roast in one, unless you go for the mini oven type rather than the drawer type.
