These zucchini chips are amazing! Coated with olive oil, spices and parmesan, then baked into crispy perfection, they're one of my favorite ways of making zucchini for my family.
The secret to making them crispy? Salt them to draw water out, then bake them in a hot 425°F oven.
I love zucchini, especially those firm in-season zucchini with smooth dark-green skin and firm flesh. It's no wonder I have several zucchini recipes on this website! They're all excellent, but this is definitely one of the best.
These zucchini chips are so good. It's one of my favorite side dishes to make when zucchini are in season. It helps that my family loves them too - even the Picky Eater! So I tend to make them once or even twice a week.

Ingredients
You'll only need a few simple ingredients to make these tasty chips. The exact measurements are included in the recipe card below. Here's an overview of what you'll need:
Olive oil spray: I love cooking with this delicious oil. But if you'd rather use an oil with a higher smoke point, you can use avocado oil instead. Melted butter is another tasty option.
Fresh zucchini: It's best to use small, firm zucchinis in this recipe. You don't want them large and watery.
Kosher salt and black pepper: If using fine salt, you should reduce the amount you use, or the chips could end up too salty.
Garlic powder: Sometimes I use onion powder. But garlic is best.
Grated Parmesan: Make sure you use finely grated parmesan, not coarsely shredded.
Instructions
It's so easy to make these zucchini chips! I season them with olive oil, garlic, and parmesan and bake them in a hot oven until crispy. I keep them gluten-free and keto by avoiding breadcrumbs and using just grated Parmesan to coat them.
Scroll down to the recipe card for detailed instructions. Here are the basic steps:
Slice the zucchinis thinly, salt the slices, then rinse and dry them. This step helps get rid of some of the water content of the zucchinis, which helps prevent sogginess.
Spray the slices with olive oil and bake them in a 425°F oven for 15 minutes.
Flip the slices, spray them with more oil, and season them with salt, pepper, garlic powder, and Parmesan.
4. Bake the chips for 15-20 more minutes, until browned and crispy.
Expert tips
- Salting the zucchini slices before baking them is an annoying extra step, but it removes water from the zucchini, which helps achieve crispiness. So I don't recommend skipping this step. I tried, and the chips were still delicious, but they were definitely not crispy.
- Some of the zucchini slices might be ready before others are. You can remove them to a plate and keep baking the ones that have not yet crisped up.
Frequently asked questions
Slice them thinly, salt them prior to baking them to draw water out, and bake them in a hot oven. Coating them with grated Parmesan cheese is another trick that adds to their crispiness.
Yes, provided you use low-carb ingredients. In addition to these chips, good options include eggplant chips, kale chips, Parmesan crisps, bacon chips, and salami chips.
You can use unsweetened ketchup, ranch dip, guacamole, sour cream, or a keto cheese sauce.
I tend to use three substitutes. Almond flour (or almond meal), ground pork rinds ("pork panko"), or grated Parmesan. All of them work well and each of them is better suited for different recipes. Parmesan works really well in this recipe.
Serving suggestions
I usually serve these chips as a side dish. But sometimes my kids ask me to make them for a snack, and I am very happy to oblige! They either eat them on their own or dip them in some unsweetened ketchup.
When I make them as a side dish, I like to serve them with a main dish that I can bake in the same 425°F oven. So I often serve them with one of the following:
Storing leftovers
Leftovers keep okay in the fridge, in an airtight container, for 2-3 days. But they do lose their crispiness. You can get some of the crispiness back by baking them in a 350F oven for 10 minutes.

Place the salted zucchini in a colander in the sink and let them stand for 30 minutes at room temperature. This should draw some of the water out. After 30 minutes, rinse and blot dry the zucchini slices using paper towels.

- Remove the baking sheet from the oven. Sprinkle the zucchini slices with the remaining ¼ teaspoon of kosher salt, black pepper, garlic powder, and grated Parmesan.
