You can air fry squash and zucchini in about 10 to 15 minutes at 400°F, depending on how thick you slice them.
That’s the short answer, and honestly, it’s one of the easiest side dishes you’ll ever make.
If you’ve been wondering how long do you air fry squash and zucchini, the timing mostly comes down to thickness and personal preference.
Thin rounds cook fast and get crispy, while thicker spears stay tender with a little bite.
In this post, we’ll break down exactly how long to air fry squash and zucchini, what temperature works best, and a few simple tricks to get them perfect every single time.
Let’s dive in.
How Long Do You Air Fry Squash and Zucchini?
The honest answer is that air frying squash and zucchini takes roughly 10 to 15 minutes at 400°F.
But there’s a little more to it than just tossing them in and setting a timer.
Here’s how the timing breaks down depending on how you cut them.
1. Thin Rounds (¼-inch) Take 8 to 10 Minutes
If you slice your squash and zucchini into thin rounds, they’ll cook fast.
At 400°F, expect them to be done in about 8 to 10 minutes.
Shake the basket halfway through so they brown evenly.
These come out with slightly crispy edges and are perfect for salads or grain bowls.
2. Thicker Rounds (½-inch) Take 10 to 12 Minutes
Slightly thicker rounds need a bit more time.
When you air fry squash and zucchini at this thickness, aim for 10 to 12 minutes.
They’ll still get golden edges but stay tender in the middle.
This is my favorite way to air fry zucchini because it holds up well as a side dish.
3. Spears or Half-Moons Take 12 to 15 Minutes
Cut them into spears or half-moon slices and you’re looking at 12 to 15 minutes.
The thicker pieces take longer for the heat to penetrate.
Shake the basket every 5 minutes so all sides get that nice roasted finish.
These are great for dipping or serving alongside grilled meats.
What Temperature Works Best for Air Frying Squash and Zucchini?
For the best results, set your air fryer to 400°F (200°C).
That high heat gives you that roasted, slightly charred exterior without turning the inside to mush.
Some people prefer 375°F for a gentler cook.
That works too, but you’ll need to add a couple of extra minutes.
When you air fry squash and zucchini at 400°F, you get the closest thing to oven-roasted veggies without waiting for the oven to preheat.
1. Preheat Your Air Fryer for Even Cooking
Preheating matters more than people think.
A preheated basket means your squash and zucchini start cooking the second they hit the surface.
That leads to better browning and less soggy bottoms.
Most air fryers preheat in about 3 to 5 minutes.
If yours doesn’t have a preheat setting, just run it empty at 400°F for a few minutes.
2. Don’t Overcrowd the Basket
This is the number one mistake people make when they air fry squash and zucchini.
If you pile them in, they’ll steam instead of roast.
Cook them in a single layer, and work in batches if you have to.
Trust me, the extra few minutes are worth it for that crispy, caramelized texture.
3. Pat Them Dry Before Seasoning
Squash and zucchini are mostly water, and water is the enemy of crispiness.
After slicing, lay them on a paper towel and pat them dry.
Then toss with a little olive oil, salt, pepper, and any seasonings you love.
A light coating of oil helps them brown, but don’t overdo it.
One or two teaspoons is usually plenty for a whole batch.
Tips for Perfectly Air Fried Squash and Zucchini
Beyond timing and temperature, a few small habits make a big difference.
Here’s what I’ve learned from making these again and again.
1. Shake the Basket Halfway Through
Every air fryer has hot spots.
Shaking the basket halfway through cooking ensures everything browns evenly.
It takes two seconds and saves you from burnt edges and pale centers.
2. Add Seasonings That Stick
Squash and zucchini have a mild flavor, so they soak up whatever you give them.
Garlic powder, smoked paprika, Italian herbs, and a pinch of parmesan all work beautifully.
Just toss everything together in a bowl before they go in the basket.
3. Watch the Last Two Minutes
Squash and zucchini can go from perfectly golden to slightly charred fast.
Keep an eye on them during the final stretch, especially if you sliced them thin.
Pull the basket out and check for doneness around the 8-minute mark for rounds.
If they’re tender and golden, they’re done.
4. Serve Immediately for the Best Texture
These veggies are best straight out of the air fryer.
As they sit, they release moisture and lose some of that crispiness.
So plate them right away and enjoy.
If you must wait, keep them in a warm oven on a wire rack.
So, How Long Do You Air Fry Squash and Zucchini?
You air fry squash and zucchini for 10 to 15 minutes at 400°F, depending on how thick you slice them.
Shake the basket halfway through, don’t overcrowd it, and pat the veggies dry before seasoning.
That’s really all it takes to turn a simple squash and zucchini into a crispy, golden side dish.
The next time you’re wondering how long do you air fry squash and zucchini, just remember: thin slices take about 8 to 10 minutes, and thicker cuts need closer to 15.
