You can air fry zucchini and squash in about 10 to 15 minutes at 400°F, depending on how thick you slice them.
That short cook time is exactly why so many people love air frying zucchini and squash for a quick weeknight side.
The hot circulating air gives them golden edges and a tender center without turning them into mush.
In this post, we’ll walk through exactly how long to air fry zucchini and squash, how to prep them, and the little tricks that keep them crispy.
You’ll also learn how to season them, how to avoid the soggy results that frustrate so many home cooks, and how to adjust the timing for different cuts.
Let’s dive in.
How Long Do You Air Fry Zucchini and Squash?
The answer depends on how you cut them, but here are the general time frames you can rely on.
1. Sliced Rounds or Half-Moons: 10 to 12 Minutes
If you slice your zucchini and squash into rounds or half-moons about a quarter inch thick, air fry them at 400°F for 10 to 12 minutes.
Shake the basket halfway through so every piece gets that even golden finish.
This is the most common way people air fry zucchini and squash, and it’s the fastest too.
2. Spears or Sticks: 12 to 15 Minutes
Cut them into thicker spears or sticks and you’ll need closer to 12 to 15 minutes.
Thicker pieces take longer because the heat has to travel further to the center.
Toss them once or twice during cooking so the edges crisp up nicely on all sides.
3. Cubes: 12 to 14 Minutes
Cubed zucchini and squash land somewhere in the middle at around 12 to 14 minutes.
They’re great for bowls, pasta, and meal prep because they hold their shape well.
Just keep the cubes roughly the same size so they cook at the same rate.
4. Whole Small Zucchini: 18 to 20 Minutes
You can even air fry whole small zucchini and squash if you prick them a few times with a fork first.
This takes 18 to 20 minutes, and you’ll want to turn them once halfway through.
It’s a fun way to serve them stuffed or sliced open later.
No matter which cut you choose, always preheat your air fryer for a few minutes, because a hot basket starts the crisping right away.
How to Prep Zucchini and Squash for the Air Fryer
Good prep is the difference between crispy and soggy, so here’s how to set yourself up for success.
1. Wash and Dry Them Thoroughly
Rinse your zucchini and squash under cool water, then dry them completely with a clean towel.
Extra moisture on the surface steams the veggies instead of roasting them.
That’s the number one reason people end up with sad, limp results.
2. Cut Them Evenly
Aim for pieces that are all about the same thickness.
Uneven cuts mean some pieces burn while others stay raw.
Consistency is what makes air frying zucchini and squash so reliable.
3. Toss With Oil and Seasoning
Coat the pieces lightly in olive oil, avocado oil, or even a quick spray of cooking oil.
Then season with salt, pepper, garlic powder, and paprika.
A little grated parmesan or Italian seasoning takes things up a notch too.
4. Don’t Crowd the Basket
Arrange the zucchini and squash in a single layer with a little breathing room.
If you pile them up, they’ll steam instead of crisp.
Cook in batches if you have to, because the texture is worth the extra few minutes.
Tips for Perfect Air Fryer Zucchini and Squash
These small habits make a big difference every single time.
1. Salt Them First to Draw Out Water
Sprinkle salt on the sliced zucchini and squash and let them sit for 10 minutes.
Then pat them dry before adding oil.
This pulls out excess moisture, which helps them crisp up beautifully in the air fryer.
2. Shake the Basket Halfway
Set a timer and give the basket a good shake at the halfway mark.
This simple step ensures every piece browns evenly.
It also keeps the pieces from sticking to each other.
3. Add a Light Coating for Extra Crunch
If you want them extra crispy, dust the pieces with a tablespoon of cornstarch or almond flour before air frying.
It creates a thin crust that mimics deep-fried texture without the oil.
This trick works wonders when you air fry zucchini and squash.
4. Watch the Clock the First Time
Air fryer models vary, so check your zucchini and squash a minute or two before the timer ends.
You want them tender but not collapsing.
Once you know your machine, you’ll nail the timing every time.
So, How Long Do You Air Fry Zucchini and Squash?
You air fry zucchini and squash for about 10 to 15 minutes at 400°F, depending on how thick you cut them.
Sliced rounds take 10 to 12 minutes, spears take 12 to 15, and whole small ones take about 18 to 20.
The key is drying them well, cutting them evenly, and not crowding the basket.
Once you get the hang of it, air frying zucchini and squash becomes one of the easiest sides in your rotation.
