Crispy Air Fryer Zucchini Chips, Low-Carb

Crisp, low-carb zucchini chips come down to moisture control and thin, even slicing more than any coating. This unbreaded version uses a quick salt-and-dry step so the rounds crisp up in the air fryer without going soggy.

Air fryer zucchini chips with lightly browned edges on a white plate

Zucchini chips sound simple, but most home versions come out limp instead of crisp. The fix isn’t a heavier coating — it’s controlling moisture before the zucchini ever hits the basket. Slice the rounds thin and even, salt them briefly to pull out excess water, dry them well, then give them enough room in the air fryer to actually crisp instead of steam. This recipe skips breading entirely and stays low-carb, relying on technique instead of a coating to get crisp edges.

Worth Knowing Before You Cook

The researched pattern here is straightforward: thin, well-dried zucchini slices crisp more reliably; thicker or wetter slices tend to stay soft. A mandoline (used with its hand guard) gives more consistent slices than free-hand knife cuts, which matters more for a crisp result than any coating. The second batch may behave differently, so check it earlier and rely on visual cues rather than the clock. For more on why air fryer results vary batch to batch, see the air fryer not crispy guide.

Prep Time 15 minutes
Cook Time 20 minutes
Total Time 35 minutes
Servings 2 servings

Ingredients
  

  • 1 small zucchini about 185 g / 6.5 oz, sliced into 3 mm / 1/8-inch rounds
  • 1/4 tsp kosher salt
  • 1 tsp extra-virgin olive oil
  • 1/8 tsp granulated garlic or garlic powder
  • 1/8 tsp sweet paprika
  • black pepper optional, to taste after cooking

Equipment

  • Air Fryer Basket capacity changes the number of batches and total elapsed cooking time.
  • Mandoline or sharp knife For uniform 3 mm / 1/8-inch rounds; use the mandoline hand guard.
  • Paper towels or clean absorbent kitchen towel For thoroughly drying the salted zucchini rounds.
  • Silicone-tipped tongs Optional, for turning and removing delicate rounds.

Method
 

  1. Preheat the air fryer to 175°C (350°F).
  2. Slice the zucchini evenly into 3 mm / 1/8-inch rounds. If using a mandoline, use the hand guard.
  3. Toss the zucchini rounds with 1/4 tsp kosher salt and let them rest for 10 minutes to draw out moisture.
  4. Pat the rounds very dry with paper towels or a clean absorbent kitchen towel.
  5. Toss lightly with the olive oil, garlic and paprika.
  6. Arrange the rounds in a true single layer. Cook in batches rather than overlapping the slices.
  7. Air-fry for 5 minutes, turn and check the slices, then continue for about 5 minutes more. Remove smaller slices early if already browned and crisp. Add only 1–2 extra minutes if needed, watching closely.

Notes

Makes 1–2 snack servings; nutrition is calculated using 2 servings. Cook in a true single layer; overlap traps moisture and gives softer chips. Treat the final 2–3 minutes as a watch window because thin rounds can move from browned to burnt quickly. These are best eaten immediately or the same day. To re-crisp, air-fry at about 175°C (350°F) for roughly 2 minutes, checking early. Freezing cooked zucchini chips is not recommended because the texture is likely to suffer.

Why This Recipe Works

Zucchini is mostly water, and that water has to go somewhere before the rounds can crisp.

  • A short salt rest draws moisture to the surface, and patting the slices dry removes it before cooking instead of letting it steam off in the basket.
  • Slicing to an even 3 mm (1/8-inch) thickness matters just as much — uneven rounds cook unevenly, so thicker pieces stay soft while thinner ones are already done.
  • Cooking in a true single layer, rather than overlapping, lets hot air move around every round instead of trapping steam underneath the pile.

Pro Tips

  • Salt the rounds for the full 10 minutes and pat them thoroughly dry — insufficient drying is a major cause of soggy chips.
  • Stick to 1 tsp of olive oil for the whole zucchini; more oil makes the chips greasy instead of crisp.
  • If the basket runs hot after the first batch, check the second batch a little earlier and judge doneness by sight instead of the timer.
  • These chips are best eaten the same day. Re-crisp leftovers in the air fryer at 175°C (350°F) for about 2 minutes, watching closely.

What Can Go Wrong

Chips Turn Out Soggy

Slices were too thick, not dried thoroughly, or overlapped in the basket. Slice to an even 3 mm (1/8-inch), pat the rounds dry thoroughly after salting, and cook in a true single layer.

Edges Are Burning

Slices were cut unevenly or the basket ran too hot. Keep slices a uniform 3 mm, hold the temperature at 175°C (350°F), and pull smaller or already-browned pieces out early.

Chips Are Greasy

Too much oil was used. Stick to 1 tsp of olive oil for the whole zucchini — any more makes the rounds greasy instead of crisp.

Browned but Still Soft

Trapped moisture or crowding can brown the edges before the slices crisp through. Reduce the batch size and dry the zucchini more aggressively before adding oil.

Storage & Reheating

These are best eaten immediately or the same day — they lose crispness quickly once cooled.

Re-crisp leftovers in the air fryer at 175°C (350°F) for about 2 minutes, checking early since they can go from soft to overdone quickly. Freezing cooked zucchini chips isn’t recommended; the texture doesn’t hold up.

FAQ

Why are my air fryer zucchini chips soggy?

They were likely sliced too thick, not dried thoroughly after salting, or overlapped in the basket. Slice the zucchini to an even 3 mm (1/8-inch), pat the rounds thoroughly dry, and cook them in a true single layer.

Do you need breading to make zucchini chips crispy in the air fryer?

No. This recipe uses no breading. The crispness comes from thin, even slices, removing surface moisture after salting, using only a small amount of oil, and leaving enough space for hot air to circulate.

How do you reheat air fryer zucchini chips?

Re-crisp leftovers in the air fryer at 175°C (350°F) for about 2 minutes, checking early because the thin rounds can go from soft to overdone quickly.

Required for drying: Paper towels or a clean absorbent kitchen towel.

Basket Air Fryer

A standard 4–6L basket air fryer works well here because the zucchini rounds need room for hot air to circulate. Arrange them in a single layer; smaller baskets may need an extra batch.

Mandoline or Sharp Knife

Needed for even 3 mm (1/8-inch) slices — the uniform thickness this recipe depends on. Always use the mandoline’s hand guard.
