The sweet ones with egg whites come out like the candied nuts you get at the fair. They usually take at least an hour in a regular oven, but they only take 10 minutes in the airfryer!

Pretty much, you just toss the nuts with a liquid (oil, syrup, water, egg white, etc.) & your seasoning of choice, then drop into your airfryer. I use parchment paper or aluminum foil to wrap the button of the plate so the nuts don't fall through, which also makes it easier to clean. Basic procedure is:
1. Dump the nuts in a flat row into the airfryer basket
2. Bake at 330F for 5 minutes (no preheat required)
3. Use a spoon or whatever to stir them around & flip them, then let them cook for another 5 minutes
Then just spread out on a sheet pan, cutting board, or pre-cut sheet of parchment to cool down. I like using parchment because then I don't have to clean anything up & the candied ones don't stick to the paper after cooling down & solidifying. A 200-pack is $20 on Amazon:
