If you grew up in a house where “snack” meant something crunchy, you probably understand why I got a little obsessed with air fryer chips. I wanted the deep-fried vibe without the deep-fried cleanup. The good news: an air fryer can approximate dehydrator-style drying for chips. The honest news: it is not the same as true low-and-slow dehydration unless you are running very low heat for a long time, and fruit and veggies behave very differently once the fan kicks on.
This is my at-home test of air fryer apple chips (sweet, simple, naturally sticky) versus air fryer zucchini chips (watery, temperamental, wildly satisfying when you nail them). I’ll walk you through prep, cook times, what “done” actually looks like, and how to get real crunch from both.
What I actually tested: I ran apples at 275°F vs. 300°F and compared 1/8-inch slices to 1/16-inch slices. For zucchini, I tested salted-and-blotted slices versus “straight into the basket” slices (spoiler: the straight-to-basket batch steamed).
Quick verdict
- Easiest to get crisp: Apple chips. They are more forgiving and stay snackable even if they land a little chewy.
- Most likely to go soggy: Zucchini chips. Moisture is the whole battle, and it starts before the air fryer even turns on.
- Best “potato chip” vibe: Zucchini chips, when sliced thin and dried well.
- Best for meal prep lunches: Apple chips, because they hold texture longer at room temp.
Air fryer vs. dehydrator
A dehydrator uses low heat and airflow to slowly drive off moisture. An air fryer uses stronger convection and usually higher heat. So yes, you can get “dehydrated-style” chips in an air fryer, but it is more like fast-drying with a crisping finish. That’s why:
- Chip thickness matters even more.
- Small batches win because air needs to circulate.
- You will flip, rotate, and babysit a bit.
- You may get a mix of crisp + chewy pieces, especially with fruit.
If your air fryer has a Dehydrate setting, use it. If not, you can still do this by running a low temperature and extending the time.
Apple chips
Apple chips are basically a sugar and moisture balancing act. Apples start juicy, then the moisture evaporates and the natural sugars concentrate. That is why apple chips can go from “not done” to “browned and bitter” faster than you think.
Best apples
- Honeycrisp: Great flavor and structure.
- Gala or Fuji: Sweet and reliable.
- Granny Smith: Tart, crisp, and less candy-sweet.
Skip super soft varieties if you can. Softer apples tend to dry unevenly and lean chewy.
What you need (per batch)
- 1 to 2 medium apples (about 16 to 24 slices, depending on size and how tight your basket is)
- Optional: 1 to 2 teaspoons lemon juice mixed with 1 cup water
- Seasoning: cinnamon + a pinch of salt (optional)
Apple slices should be in a single layer for best results. If you overlap, the overlapped spots stay soft.
Prep that matters
- Slice thin: Aim for 1/16 to 1/8 inch. A mandoline makes this easy, but a sharp knife works if you go slow.
- Core: You can core first or just pop seeds out after slicing.
- Optional anti-browning dip: A quick dip in lemon water helps keep them pretty, but it is not required for crunch. Pat dry before seasoning.
- Season lightly: Cinnamon and a tiny pinch of salt is my favorite. Go easy on sugar or they can burn.
Time and temp (tested range)
Option A (more even drying): 275°F for 15 to 22 minutes, flipping halfway.
Option B (faster, easier to brown): 300°F for 12 to 18 minutes, flipping halfway, then adding 2 to 6 minutes as needed.
Every air fryer runs a little hot or cool. Start checking early at the edges. Pull pieces that look ready and keep the thicker ones going.
What “done” looks like
- Edges are just barely golden, not dark brown.
- Centers look matte and dry, not glossy.
- They may feel a touch pliable right out of the basket.
- They crisp as they cool. Give them 5 to 10 minutes on a rack or plate before judging.
Zucchini chips
Zucchini chips are the friend who shows up late, needs a pep talk, and then turns out to be the life of the party. Zucchini has a very high water content (commonly in the mid-90 percent range by weight). If you do not remove some of that water before air frying, you are basically steaming it with a fan.
Two styles
You can make zucchini chips two ways:
- Naked (dehydrated-style): Just zucchini, a little oil, and seasonings. This is the closest comparison to apple chips.
- Breaded: Coated with parmesan, panko, or almond flour. Crunchier faster, but it is more of a “crispy coating” snack than a dehydrated chip.
For this comparison, we are talking naked zucchini chips.
What you need (per batch)
- 1 medium zucchini (you will usually need to cook in 2 to 4 batches)
- Salt: about 1/4 teaspoon for sweating, then season to taste after cooking
- Oil: 1 teaspoon, or a very light mist
- Seasonings: garlic powder, smoked paprika, Italian seasoning, lemon pepper, or ranch seasoning
Salt is powerful here. Use enough to draw moisture, then do most of your flavor seasoning after cooking so you do not end up with salty chips.
Prep that makes or breaks them
- Slice very thin: 1/16 inch is ideal. If you can see through it a little, you are in the right zone.
- Salt to draw moisture: Lay slices on paper towels, sprinkle with salt, and rest 10 to 20 minutes.
- Blot aggressively: Press with more towels until the surface is dry. This step is the difference between crisp chips and limp rounds.
- Oil lightly: A small amount helps browning, but too much makes them greasy and less crisp.
Time and temp (tested range)
325°F for 10 to 16 minutes, flipping at least once, and rotating trays or the basket if your air fryer has hot spots.
If your zucchini slices are thicker than you think, plan on 16 to 22 minutes total, and pull the smaller ones early.
What “done” looks like
- Edges are browned and the centers look dry, not glossy.
- They feel light when you lift them.
- They will crisp more as they cool, but zucchini needs to be noticeably dried in the basket first.
Apple vs. zucchini in the basket
Moisture
Apples: Moisture evaporates steadily and sugars concentrate. Your main risk is over-browning.
Zucchini: Moisture releases fast and can pool. Your main risk is steaming. That is why salting and blotting are non-negotiable if you want crunch.
Slice tolerance
Apples: You can get away with slightly thicker slices and still end up with a chewy-crisp snack.
Zucchini: Too thick means limp. Period.
Seasoning
Apples: Cinnamon, pumpkin pie spice, chai spice, or just salt. I skip heavy sweeteners.
Zucchini: Garlic powder, smoked paprika, Italian seasoning, ranch seasoning, or lemon pepper. Add a pinch of sugar only if you love that sweet-salty vibe.
Crunch tips
- No overcrowding: Chips should be in a single layer with breathing room. No overlap if you want real crunch.
- Use a rack if you have one: It improves circulation and reduces the steamed-underside problem.
- Flip and rotate: It is worth it, especially for zucchini.
- Cool before you judge: Both chips firm up as they cool.
- Store only when fully cool: Any trapped warmth equals condensation, and condensation equals sadness.
- Expect a mixed batch: Pull done chips early and keep going with the rest.
Basket vs. oven-style air fryer
- Basket models: Tend to need more shaking or flipping because the bottom pieces can steam.
- Oven-style with trays: Easier to do larger batches, but rotate trays top-to-bottom halfway through for even drying.
Parchment note: If you use perforated parchment, keep it weighed down with chips so it does not lift into the heating element. A rack is usually the better move for airflow.
Timing cheatsheet
| Chip type | Temp | Time | Flip? | Biggest risk |
|---|---|---|---|---|
| Apple chips | 275 to 300°F | 12 to 22 min | Yes, halfway | Over-browning |
| Zucchini chips | 325°F | 10 to 22 min | Yes, at least once | Steaming, sogginess |
Reminder: These are ranges, not commandments. Slice thickness and your air fryer model will move the needle.
Serving ideas
Apple chips
- With peanut butter or sunflower seed butter
- Crumbled over vanilla yogurt
- With cheddar slices for a sweet-salty plate
Zucchini chips
- With hummus or ranch dip
- Alongside sandwiches instead of crackers
- Sprinkled with parmesan right after cooking (it clings best while warm)
Troubleshooting
Why are my apple chips chewy?
Most commonly they are sliced a little thick or just need more time. Put them back in at 275 to 300°F in 2 to 3 minute bursts. Also, let them cool fully. Warm apple chips always feel softer than they end up.
Why did my apple chips turn bitter?
Over-browning. Next time, lower the heat slightly (try 265 to 285°F if your air fryer allows it) and pull the smallest slices early.
Why are my zucchini chips soggy?
Either the slices were too thick, the basket was crowded, or the zucchini was not dried enough before cooking. Salt, rest, and blot more than you think you need to, and cook in smaller batches.
Can I make zucchini chips without oil?
You can, but browning is harder and sticking is more likely. I prefer a very light mist of oil for more even color and better crunch.
FAQ
Do I need a dehydrate setting?
No. A dehydrate setting is convenient, but you can still make great chips with low temps and longer cook times. The key is thin slices, single layers, and checking often.
How long do homemade chips stay crisp?
Apple chips usually hold well for 1 to 2 days at room temp if they are fully dried and stored airtight. Zucchini chips are best the same day. They can soften overnight because they reabsorb moisture easily.
How do I re-crisp chips?
Spread them in a single layer and air fry at 300°F for 2 to 4 minutes, then cool for a few minutes. This works best for zucchini and “almost crisp” apple chips.
Can I do both at the same time?
I would not. Apples and zucchini release moisture differently, and you will end up with uneven drying. Make one batch, let the basket cool a few minutes, then start the next.
Bottom line
If you want an easy win, start with apple chips. They are the gateway chip: quick, forgiving, and kid-approved. If you want a savory, “how is this not fried?” crunch, go for zucchini chips, but treat moisture removal like your part-time job.
And if your first zucchini batch comes out a little floppy, welcome to the club. I once managed to explode a marshmallow in my air fryer, so you are already ahead.
