Ingredients You’ll Need
This crispy zucchini chips recipe keeps things refreshingly simple. Here’s everything broken down so you can shop fast and start snacking faster.
| Category | Ingredient | Amount |
|---|---|---|
| Produce | Medium zucchini (about 6 oz each) | 2 |
| Oil | Olive oil spray | As needed |
| Seasoning | Diamond Crystal kosher salt | 1 tsp |
| Seasoning | Black pepper | 1/4 tsp |
| Seasoning | Garlic powder | 1/2 tsp |
| Cheese | Parmesan, grated (not shredded) | 1/4 cup |
A quick note on salt: Diamond Crystal kosher salt is less salty by volume than table salt or Morton’s kosher. If you’re using a different brand, cut the amount in half to avoid over-salting your chips.
Parmesan tip: Always go for finely grated Parmesan here, not shredded. Finely grated melts and crisps up beautifully, while shredded stays clumpy and won’t give you that gorgeous golden crust.
How to Make Crispy Zucchini Chips (Step-by-Step)
The process is straightforward, but a few key steps make the difference between crispy perfection and soggy disappointment. Follow along and you’ll nail it on the first try.
Step 1: Preheat and Prep Your Pan
Preheat your oven to 425 degrees F. Line a rimmed baking sheet with high-heat-resistant parchment paper and give it a good coat of olive oil spray. The high temperature is what gives these baked zucchini chips their crunch, so don’t skip preheating!
Step 2: Slice the Zucchini Thin
Slice your zucchini into rounds about 1/8-inch thick. Consistency matters here — thicker slices won’t crisp properly, and uneven slices will cook at different rates. A mandoline slicer makes this a breeze, but a sharp knife works just fine too.
Step 3: Salt and Wait (This Step Is Non-Negotiable)
Arrange the zucchini rounds on paper towels and sprinkle them with kosher salt. Let them sit at room temperature for a full 30 minutes. This draws out the excess moisture that would otherwise steam your chips instead of crisping them up.
After 30 minutes, blot the rounds thoroughly dry with more paper towels. Remove the surface water and some of the salt — no rinsing needed. Don’t rush this step. It’s the difference between crispy and chewy, and you want crispy.
“The salt-and-wait method is the real secret behind truly crispy zucchini chips. Think of it as a spa treatment for your zucchini — it needs that time to release what it’s holding onto.”
Step 4: Arrange and Start Baking
Lay the zucchini slices in a single layer on your prepared baking sheet. No overlapping — give each slice its own space to breathe and crisp. Spray lightly with olive oil and slide the pan into the oven for 15 minutes.
Step 5: Season with Parmesan and Finish Baking
Pull the pan out and sprinkle the slices with black pepper, garlic powder, and that glorious grated Parmesan. There’s no need to flip them at any point — just season and return the pan to the oven.
Bake for another 15 to 20 minutes, checking every 5 minutes. The chips won’t all finish at the same time, so pull out the golden, crisp ones as they’re ready and let the rest keep going. Transfer finished chips to a plate and serve immediately while they’re still crunchy.
These pair wonderfully alongside easy sheet pan chicken fajitas for a casual weeknight dinner spread.
Expert Tips for the Best Baked Zucchini Chips
Don’t Skip the Salting Step
Seriously, this is the most important tip. Zucchini is about 95% water, and that moisture is the enemy of crispiness. The 30-minute salting rest is what pulls it out before it can sabotage your chips in the oven.
Use Parchment, Not Foil
Foil can cause the bottoms to steam rather than crisp. High-heat parchment paper keeps things dry and lets the heat circulate properly underneath each slice.
Give Them Space
Crowding the pan is a one-way ticket to soggy chips. If your slices don’t all fit in a single layer, use two baking sheets. More space equals more crunch, every time.
Watch Them Closely in the Final Minutes
Once the Parmesan goes on, things move quickly. Keep an eye on the oven and rotate the pan if your oven has hot spots. You want golden brown, not burnt black.
Serve Immediately
Like most crispy snacks, these zucchini chips are at their absolute best straight out of the oven. They will soften as they sit, so plan to eat them right away. If you’re hosting, time your baking so they come out just before guests grab their first chip.
Variations and Fun Twists on This Zucchini Snack Recipe
Air Fryer Zucchini Chips
Got an air fryer? This recipe translates beautifully. Follow the same salting and seasoning steps, then air fry at 375 degrees F in a single layer for about 10 to 12 minutes, checking frequently. Air fryer zucchini chips tend to crisp up faster, so keep a close eye on them in the last few minutes.
Spicy Kick Version
Add 1/4 teaspoon of cayenne pepper or a pinch of red pepper flakes along with the garlic powder and black pepper. The heat plays beautifully against the salty Parmesan crust. Pair these spicy chips with a cool Japanese cucumber salad for a refreshing contrast.
Everything Bagel Seasoning
Swap the garlic powder and black pepper for 1/2 teaspoon of everything bagel seasoning. It’s a fun, punchy twist that makes this zucchini snack recipe feel totally fresh.
Vegan Option
Skip the Parmesan and use nutritional yeast instead. It gives a similar savory, nutty flavor while keeping the recipe fully plant-based. Use about 2 tablespoons in place of the 1/4 cup Parmesan.
Troubleshooting: Why Aren’t My Chips Getting Crispy?
They’re Still Soggy After Baking
Nine times out of ten, this comes down to moisture. Either the salting step was rushed, or the slices weren’t blotted dry enough. Make sure you really press those paper towels down firmly to absorb all the surface water before baking.
They Burned on the Edges Before Crisping in the Center
Your slices are probably uneven. Try to keep all your rounds the same thickness so they cook at the same rate. A mandoline slicer is worth every penny for this recipe.
The Parmesan Isn’t Getting Golden
This usually means the cheese was shredded rather than finely grated. Finely grated Parmesan melts flat and crisps up into that golden crust. Shredded cheese is too chunky and stays soft. Switch to grated and you’ll see the difference immediately.
Storage Instructions and Reheating
Honestly? These are best eaten immediately. But if you have leftovers, here’s how to handle them properly.
| Storage Method | Container | Duration | Notes |
|---|---|---|---|
| Room temperature | Airtight container | Up to 1 day | They will soften over time |
| Refrigerator | Airtight container | Up to 2 days | Re-crisp in oven before serving |
| Freezer | Not recommended | N/A | Texture becomes too soft after thawing |
To reheat: Spread leftover chips on a baking sheet and bake at 400 degrees F for 5 to 8 minutes until they crisp back up. The air fryer also works great — 375 degrees F for 3 to 4 minutes does the trick.
No-waste tip: If your chips have gone soft and won’t re-crisp, crumble them over soups, salads, or pasta as a crunchy, savory topping. They’re also amazing crumbled over scrambled eggs for a fun breakfast twist.

FAQs About Crispy Zucchini Chips
Can I make air fryer zucchini chips with this recipe?
Absolutely! Follow the same prep steps — salting, blotting dry, and seasoning — then air fry at 375 degrees F for 10 to 12 minutes. Air fryer zucchini chips tend to cook faster than oven-baked, so check them early and pull out the crispy ones as they finish.
Why do my zucchini chips come out soft instead of crispy?
The most common culprit is moisture. Make sure you salt the slices and let them rest for the full 30 minutes, then blot them very dry before baking. Crowding the pan is another big factor — overlapping slices steam each other instead of crisping up.
Do I need to peel the zucchini before slicing?
Nope, no peeling needed. The skin adds a nice bit of color and texture, and it crisps up just fine in the oven. Just give the zucchini a good rinse before slicing and you’re good to go.
Can I use yellow squash instead of zucchini?
Yes! Yellow summer squash works beautifully with this same method and seasoning. The flavor is slightly sweeter, which pairs really nicely with the salty Parmesan crust. Just make sure to cut it to the same 1/8-inch thickness for even cooking.
What should I serve with this zucchini snack recipe?
These chips are great on their own, but they shine as a side dish too. Try them next to Greek-seasoned turkey burgers, loaded breakfast burritos, or even tucked alongside Japanese katsu bowls with tonkatsu sauce for a fun fusion snack spread.
