Yes! Potatoes in the air fryer are my favorite! They turn out so crispy in less time. The only downside is that you can't make nearly as many potatoes at one time in the air fryer. But if you're only making enough Irish nachos for a couple of people, it should work. Try air frying your potato slices at 400 degrees for 20-25 minutes. You may need to add a little more time if you want REALLY crispy potatoes!
