- Scrub and slice potatoes thinly using a mandoline or sharp knife. We’re going for see-through here. 
- Soak slices in cold water for 30 minutes. Trust me, this makes 'em crisp. 
- Drain and pat dry completely. No soggy chips allowed. 
- Toss slices in olive oil and salt. Add your favorite seasonings if you’re feeling fancy. 
- Preheat air fryer to 360°F (182°C). 
- Place potato slices in a single layer in the air fryer basket. Don’t overcrowd. 
- Air fry for 15–18 minutes, flipping halfway. Keep an eye on them near the end—they go from golden to gone real quick. 
- Let them cool a bit (if you can wait). Serve with dip or devour plain.
