15-Minute Crispy Air Fryer Zucchini Chips

These air fryer zucchini chips turn a humble squash into a crunchy, salty snack or side in about 15 minutes — no deep frying required. A light coating of cornstarch and a hot blast of air give them a crackly outside with a tender middle, exactly what you want when the craving for something crispy hits and you don’t want to stand over a pot of oil.

They come out golden and speckled with seasoning, with edges that shatter a little when you bite. Use them as a side with burgers, pile them on a plate for a movie snack, or just eat them straight from the basket while they’re still hot.

Why These Air Fryer Zucchini Chips Are a Keeper

The air fryer does all the heavy lifting here. There’s no messy breading station and no splattering oil on the stovetop, just a quick toss and a short cook. The cornstarch is the quiet trick that helps draw out surface moisture so the chips actually crisp instead of steaming.

I keep coming back to this one because it scales up fast. Two zucchini turn into a snack for two in ten minutes of cook time, and the seasoning changes easily when you want a different flavor. Garlic powder, smoked paprika, a hit of cayenne — they all work.

Ingredients

• 2 medium zucchini, about 6 to 7 inches each: yellow squash works the same way.
• 1 tbsp olive oil: helps the coating stick and encourages browning.
• 2 tbsp cornstarch: the key for a thin, crisp shell.
• ½ tsp kosher salt, plus more for finishing: use half the amount if your salt is fine grain.
• ¼ tsp black pepper
• ¼ tsp garlic powder
• ¼ cup finely grated parmesan (optional): adds a savory layer and helps crisp even more.

Variations / Substitutions

• Use yellow squash: slice the same way and follow the same cook time, the chips will be a little sweeter.
• Swap the seasoning: smoked paprika, onion powder, or a pinch of cayenne all work. Keep the salt and pepper as a base.
• Skip the parmesan: the chips stay dairy‑free, they just won’t have quite the same deep savory crunch.
• No cornstarch: tapioca starch or arrowroot powder swap in measure for measure.

How to Make Air Fryer Zucchini Chips

Step 1: Slice the Zucchini

Preheat your air fryer to 400°F (200°C). Wash the zucchini, trim the ends, and slice them into even ¼‑inch rounds. A steady, consistent cut means every chip finishes at the same time so you don’t end up with a basket of half‑burnt, half‑limp rings. Pat the slices very dry with a clean kitchen towel or paper towels. Any surface moisture left on the zucchini will steam in the hot air instead of crisping, so take an extra 30 seconds here.

Step 2: Coat with the Crisp Mixture

Toss the dry zucchini rounds with the 1 tbsp olive oil in a large bowl until every slice is lightly slicked. In a small bowl, whisk together the 2 tbsp cornstarch, ½ tsp salt, ¼ tsp pepper, and ¼ tsp garlic powder. Add the parmesan now if you are using it. Sprinkle the dry mix over the oiled zucchini and toss again until no dry patches remain. The coating will look thin and a little powdery — that is exactly right.

Step 3: Lay Them in a Single Layer

Tip the coated rounds into the air fryer basket and spread them out. They need space; a little overlap is okay but a crowded pile will steam. If your air fryer is on the smaller side, cook in two batches. It’s worth the extra few minutes for chips that come out crackly all over rather than soft in the middle.

Step 4: Air Fry Until Golden

Cook at 400°F for 8 to 10 minutes, flipping the chips with tongs or a spatula at the 5‑minute mark. The cornstarch will start to look dry and blistered at the edges, then turn pale gold. Start checking around 8 minutes since air fryer models run differently. You want a deep golden color all over with darker spots on a few edges, not pale and floppy.

Step 5: Serve Them Hot

Move the chips to a plate in a single layer right when they come out of the basket. Sprinkle with a light pinch of salt while they’re still hot so it sticks. Any stacking or piling now will trap steam and soften the chips fast. Eat them straight away while the edges are still audibly crisp.

Tips for the Crispiest Zucchini Chips

• Pat them bone‑dry: before the oil even goes near them. Even a little water on the surface creates steam in the air fryer and turns the coating gummy.
• Slice close to ¼ inch thick. Thicker rounds take longer to cook and stay soft in the center. Thin rounds burn before the outside sets.
• Don’t skip the cornstarch. It’s what gets you that thin, shattery shell without a heavy batter. Without it the chips will brown but stay chewy.
• Serve as soon as they come out. Zucchini chips lose their snap within a few minutes of sitting on a plate, so plan to eat them hot.

Timing shifts a bit with slice thickness:

Storing Leftover Chips

These chips are at their best right out of the air fryer and soften quickly once cooled. If you have leftovers, store them in an airtight container in the fridge for up to a day. To bring back some crunch, spread them out in the air fryer at 350°F for 1 to 2 minutes. They won’t be as shatter‑crisp as the first round, but they’ll perk up enough for a quick snack.

What to Serve With Zucchini Chips

The salty, garlicky crunch makes them a natural mate for a classic smash burger or a grilled chicken sandwich. They also hold up next to a piece of simply seared fish. If you are serving them as a snack, a little bowl of ranch, garlic aioli, or a quick yogurt‑lemon dip rounds them out without fuss.

Frequently Asked Questions

Can I make these without the cornstarch?

Yes, but the chips will be chewy rather than crisp. The cornstarch pulls surface moisture and forms a thin, brittle coating that other starches can’t quite replicate. If you must skip it, air fry the slices naked with just oil and salt and expect a softer, roasted‑zucchini texture.

Why did my chips burn in some spots and stay soft in others?

Uneven slicing and overcrowding are the two most common culprits. A few extra‑thin rounds will burn before the thicker ones finish, so aim for a consistent ¼‑inch cut. Too many chips in the basket traps steam, so give them room to breathe even if it means cooking in two rounds.

What dipping sauces go well with these?

Creamy, cool sauces contrast the hot, salty chips nicely. Ranch, a quick lemon‑garlic aioli, or a chipotle mayo all work. A simple Greek yogurt with lemon juice and a pinch of salt is a lighter option.
