Why most air fryer zucchini turns out soggy
A few summers ago I coated some zucchini slices in breadcrumbs, popped them in the air fryer, and ended up with the most incredible Air Fryer Zucchini Chips.
Then I wanted that same crispy edge with no breading at all, which is how this air fryer zucchini happened. Just a little oil, some dried herbs, and 9 minutes in the basket.
Here is the part nobody really talks about though. Zucchini is around 95% water, so without breadcrumbs to soak that up, all of that moisture has to go somewhere or you end up with steamed squash instead of roasted.
That is why the pieces get salted and left alone for 10 minutes before anything else happens. You will see actual beads of water come to the surface, you blot them off, and THEN the oil and seasonings go on.
It is an extra 10 minutes of doing absolutely nothing, and it is the reason these come out crispy on the edges with a tender middle instead of soggy. Skip it and you will taste the difference.
Since every inch is exposed to the hot air, they still cook up in almost HALF the time it would take in the oven. Not bad for a side dish that is basically zucchini, oil, and whatever dried herbs are already in the cabinet.
Ingredients and Substitutions
For the exact measurements and detailed instructions, please see the recipe card below.
- Zucchini: Medium ones are the pick here, since the giant end-of-summer squash have more seeds and a lot more water in them. Leave the skins on for color and texture, and skip the peeler entirely.
- Oil: Avocado oil is my go-to for air frying since it has a high smoke point and a mild taste. Safflower or sunflower work too, and olive oil is fine if that is what you have, it will just smoke a little more.
- Garlic powder: This is easier to distribute evenly over every piece than fresh garlic, which tends to scorch in a basket that hot.
- Dried basil and oregano: This combination is the one I come back to, but parsley, rosemary, and thyme all work. A teaspoon of Greek Seasoning can stand in for the herbs, garlic powder, and paprika all at once.
- Paprika: A little goes in to round out the herbs so they do not taste flat.
- Salt: This one does double duty. Some goes on early to draw water out of the zucchini, and the rest seasons the pieces right before they cook.
How to Make Air Fryer Zucchini
Please see the recipe card below for the full instructions, ingredient amounts, and a printable recipe.
Cut the zucchini into even pieces.
Trim the ends, slice each zucchini in half lengthwise, then into quarters, and chop into ½-inch pieces. Even pieces cook evenly, so it is worth the extra few seconds here.
Salt it and walk away.
Toss the pieces with about half the salt and spread them out on a clean dish towel or a few paper towels for 10 minutes. You will see water bead up on the surface, which is exactly what you want.
This is the step that keeps them crispy. Zucchini is around 95% water, and with no breading here to soak that up, the moisture will steam your pieces instead of roasting them.
Blot it dry and season.
Pat the pieces dry with a paper towel, move them to a large bowl, and drizzle with the oil. Sprinkle on the remaining salt, pepper, garlic powder, basil, oregano, and paprika, then toss gently until every piece is coated.
Preheat and load the basket.
Preheat the air fryer to 400°F for at least 3 minutes, then spread the zucchini in a single layer with a little space between the pieces. Work in two batches if they do not all fit.
Crowding is the other thing that makes zucchini soggy. Pieces that touch trap steam against each other, so running a half-full basket twice beats packing it once.
The Air Fryer I Use and ❤️
I use a 6-quart air fryer for this recipe and it’s the perfect size for cooking everything in a single layer without overcrowding. Because remember, keeping it in one layer is key to all that crispy goodness!
Air fry for 8 to 9 minutes.
Cook at 400°F for 8 to 9 minutes, tossing the basket about halfway through so every side gets some color. They are done when the edges are browned and a piece gives easily to a fork.
If your air fryer only does 10-degree increments, 390°F works just fine. Start checking them a minute early since every model runs a little differently.
Oops! What did I do wrong?
Why is my air fryer zucchini soggy? Almost always one of two things, either the salting step got skipped or the basket was too full. Zucchini needs a way to release its water and enough room for hot air to reach every surface.
Do I really have to salt it first? For this version, yes. Breaded recipes get away with skipping it because the coating absorbs the water, and there is no breading here to do that job.
Can I cook it at a lower temperature? You can, but you will trade crispy edges for softer pieces. At 400°F the outside browns before the inside has time to break down, which is the whole point.
Do I need to peel the zucchini? Nope, and I would leave the skin right where it is. It holds each piece together in the basket and adds color and fiber.
Can I use yellow squash instead? Yes, and the method is identical. Yellow squash tends to run a little softer, so start checking on the early side.
FAQs
Yes! Sprinkle the zucchini with salt and let it sit for about 20 to 30 minutes to draw out excess moisture. Pat it dry before seasoning and air frying for the crispiest results.
You can slice the zucchini and mix the seasonings a few hours ahead of time, but wait to salt the zucchini until just before cooking. Salting too early can make it release too much moisture.
Excess moisture is usually the culprit. Salting and drying the zucchini first, avoiding overcrowding the air fryer basket, and cooking in a single layer will help it brown and crisp up.
No. The skin is tender, edible, and helps the zucchini hold its shape while cooking.
Store leftover zucchini in an airtight container in the refrigerator for up to 3 to 4 days. Reheat in a 350°F air fryer for 2 to 3 minutes to restore some of the crispiness. The microwave will make it soft.
Freezing isn’t recommended. Zucchini contains a lot of water, so it becomes mushy and watery once thawed.
Preheating isn’t required for every model, but it helps the zucchini start cooking immediately and can improve browning and crispness.
Garlic powder, paprika, Italian seasoning, Parmesan cheese, lemon pepper, Cajun seasoning, and fresh herbs are all great options for adding extra flavor.

What to serve with air fryer zucchini
The air fryer is busy for those 9 minutes, so I build the rest of the plate around something on the stovetop or already in the oven. Fish is the easiest match, since it finishes in about the same window.
Garlic Butter Cod comes together in one skillet while the zucchini cooks, and that garlicky butter is SO good spooned over both. Parmesan Crusted Cod is the move if you want the oven doing the work instead.
For something with a little more going on, Fiesta Lime Chicken gives you a big bold main next to a simple herby side. A scoop of Mediterranean Yellow Rice rounds it into a full dinner without turning on anything else.
On a really hot night I skip the extra cooking entirely and put a cold Cucumber Tomato Salad on the table alongside. And if the zucchini pile is genuinely out of control, Air Fryer Zucchini Fries are where the rest of it goes.

My air fryer skips 380 degrees. Should I go for 370 or 390?
I would go with 390, but be sure to check it a little early.
