An air fryer turns apple chips into one of the fastest dehydrating projects on this site — most batches finish well within a single afternoon, compared to the better part of a day in a standard dehydrator or oven. It’s a good weeknight project if you’ve got apples that need using up and don’t want to commit an entire day to drying them.
Prepping the Apples
Wash the apples, core them, and slice into rounds about 1/8 inch thick — thin, consistent slices are especially important in an air fryer given the smaller, more concentrated airflow compared to a full-size dehydrator. Peeling is optional. If you want to reduce browning, dip slices briefly in a bowl of water with a splash of lemon juice before loading the basket, then pat dry.
Air Fryer Method Step by Step
- Core apples and slice into 1/8-inch rounds. Optional: dip in lemon water to reduce browning, then pat dry.
- If your air fryer has a dedicated dehydrate setting, use it (typically around 175°F) and arrange slices without overlapping.
- If using the regular cooking mode at its lowest setting instead (often around 300°F), slices can overlap slightly and cook faster.
- Dehydrate-setting batches: dry about 3 hours, checking periodically. Low-temp regular-mode batches: check starting around 15 minutes, since this runs much hotter and faster.
- Work in batches if the basket is crowded — apples need airflow on all sides to dry evenly rather than steam.
- Apples are done when dry to the touch and either leathery (chewier) or crisp (chip-like), depending on preference.
- Cool completely on a rack before storing — they crisp up further as they cool.
Why Times Vary So Much Between Air Fryers
The range above is wide because air fryer models genuinely differ this much. Models with a true dehydrate function run low and slow, closer to how a dedicated dehydrator works, and take a few hours. Models without one, run instead at their lowest regular cooking temperature (often 300°F or similar), work far faster but more resemble baking than true dehydrating — expect a result closer to a baked apple chip than a slow-dried one. Neither approach is wrong; they just produce slightly different textures and require watching the batch closely rather than trusting a single fixed time.
If your air fryer’s lowest setting is still fairly hot (250°F or above), check your first batch every few minutes rather than walking away — apple chips can go from underdone to burnt surprisingly fast at that temperature range.
How to Tell They’re Done
Apples are done when they no longer feel wet or tacky and have either a leathery, chewy texture or a crisp, chip-like snap, depending on how far you dried them. They’ll firm up somewhat as they cool, so a chip that seems slightly underdone straight from the basket is often closer to finished than it feels — let a piece cool for a few minutes before making a final call.
Storage
Store cooled apple chips in an airtight container in a cool, dark place. Chips dried at higher, faster air fryer settings tend to have a shorter realistic shelf life than a slower dehydrator batch, since the drying can be less thorough throughout — plan to eat them within a couple of weeks to a month rather than treating them as long-term storage.
Common Mistakes to Avoid
Overcrowding the basket is the single biggest issue specific to air fryer dehydrating, since the compact space means pieces that touch or overlap block airflow far more noticeably than they would in a larger dehydrator or oven. Run smaller batches with real space between pieces rather than trying to fit everything in one go.
The second is not adjusting expectations for a “low” regular-mode temperature that’s actually still fairly hot. If your model doesn’t have a true dehydrate setting, treat the process more like a slow bake than a gentle dry, and check far more frequently than the times suggested for a true dehydrate-mode batch. It’s easier to add a few more minutes than to rescue a batch that’s already scorched.
Frequently Asked Questions
No — the skin dries fine and adds a bit of extra chew. Peeling is purely a texture preference.
Slight overlap is more forgivable at higher, faster regular-mode temperatures, but for a true dehydrate setting, keep slices in a single layer without touching for the most even results.
Yes — use the lowest available regular cooking temperature instead. It will run hotter and faster than a true dehydrate mode, so check the batch frequently to avoid over-browning or burning.
Yes, and it’s worth using for the more consistent thickness across the whole batch, which matters more in an air fryer’s smaller, more concentrated airflow than it does in a larger dehydrator or oven.
