Salt zucchini slices (1cm / ⅜ inch thick) for 10-15 minutes to draw out water, pat dry, toss with oil, then air-fry at 200°C / 400°F for 8 to 10 minutes, shaking halfway. Without the salt-and-drain step, zucchini steams in its own water and goes soggy. Sticks take 10-12 min, wedges 12-15. Finish with parmesan or lemon.
| Size | Time |
|---|---|
| Slices / coins (1cm / ⅜ inch) | 8–10 min |
| Sticks (1cm × 6cm) | 10–12 min |
| Wedges (lengthwise quarters) | 12–15 min |
Edges should be golden brown and slightly crisp. Inside, the texture is tender but holds its shape — not mushy. If pieces are still pale and watery, give them 2-3 more minutes; the salt-and-drain step is critical for browning.
Zucchini is 94-95% water — that's why it goes from raw to soggy so easily. Salting draws moisture out through osmosis: salt creates a higher concentration outside the cell walls, and water flows out to balance. Once that water is gone, what's left can actually brown rather than steam. Skip this step and air-fryer zucchini becomes a wet mess.
Read the science →Yes if you want crisp edges. Zucchini is 94-95% water; without drawing some out first, it steams in its own juice and goes soggy. 10-15 minutes of salting and a thorough pat-dry transforms the result.
Almost always skipping the salt-and-drain step, or crowding the basket. Both cause steam to build up. The salt-drain removes the moisture before it can interfere; single-layer cooking lets remaining steam escape.
Yes — slice very thin (3-4mm / ⅛ inch), salt and drain thoroughly, toss with oil and seasoning, then cook at 175°C / 350°F for 12-15 minutes (lower temp prevents burning the thin slices). Watch carefully in the last 3 minutes.
No. The skin is tender, edible, and crisps nicely in the air fryer. It also holds the shape of the slice while the inside cooks. Peeling is purely aesthetic and not worth the extra prep.
