These Crispy Parmesan Zucchini Chips are thin, golden, savory, and wonderfully crunchy around the edges. They make an easy low-carb snack, appetizer, side dish, or healthy alternative to potato chips. Salting and drying the zucchini first helps remove excess moisture, which is one of the keys to getting them crisp.
Recipe Details
Prep Time: 30 minutes
Cook Time: 25–35 minutes
Total Time: About 1 hour
Servings: 4
Difficulty: Easy
Style: Baked, low-carb, vegetarian
Ingredients
For the Zucchini Chips
2 medium zucchini
½ cup finely grated Parmesan cheese
1 tablespoon olive oil
½ teaspoon garlic powder
¼ teaspoon black pepper
¼ teaspoon salt, or less depending on the Parmesan
½ teaspoon Italian seasoning
Nonstick cooking spray or a little extra olive oil
Optional for Extra Crunch
¼ cup finely crushed pork rinds for a very low-carb version
¼ cup gluten-free panko for a crispier coating
Traditional baked versions also use breadcrumbs or panko with Parmesan, while a Parmesan-only version keeps the recipe lower in carbohydrates.
Instructions
1. Preheat the Oven
Preheat your oven to 425°F (220°C).
Line a large baking sheet with parchment paper and lightly spray it with cooking spray.
A hot oven helps the zucchini lose moisture and become crisp.
2. Slice the Zucchini
Wash and dry the zucchini thoroughly.
Slice into very thin rounds, approximately â…› inch thick.
Try to keep all the slices similar in thickness so they cook evenly.
A mandoline slicer makes this step easier, but a sharp knife works too.
3. Remove Excess Moisture
Arrange the zucchini slices on paper towels.
Sprinkle lightly with salt and let them sit for 20–30 minutes.
You’ll notice moisture collecting on the surface.
Pat the zucchini thoroughly dry with additional paper towels.
Don’t skip this step! Removing excess moisture is one of the most important tricks for crispy zucchini chips.
4. Prepare the Parmesan Mixture
In a small bowl, combine:
Parmesan cheese
Garlic powder
Italian seasoning
Black pepper
Mix well.
If you’re using panko or crushed pork rinds, stir them into the mixture.
5. Coat the Zucchini
Place the dried zucchini slices in a bowl.
Drizzle with 1 tablespoon olive oil and gently toss.
Arrange the slices in a single layer on the prepared baking sheet.
Sprinkle the Parmesan mixture evenly over each slice.
Don’t overlap the zucchini because trapped steam can prevent them from becoming crisp.
6. Bake
Bake at 425°F (220°C) for approximately 15 minutes.
Remove the baking sheet and check the zucchini.
Continue baking for another 10–20 minutes, checking every 5 minutes.
Some slices may become crispy before others, so remove individual chips as they turn golden brown and crisp.
7. Cool and Crisp
Remove the finished zucchini chips from the oven.
Let them cool on the baking sheet for 3–5 minutes.
They will firm up further as they cool.
Serve immediately for the best crunch.
Easy Dipping Sauce
Creamy Garlic Dip
½ cup Greek yogurt
1 tablespoon mayonnaise
1 small garlic clove, minced
1 teaspoon lemon juice
¼ teaspoon Italian seasoning
Pinch of salt
Black pepper, to taste
Mix everything together and refrigerate for 10–15 minutes before serving.
Other Great Dips
Marinara sauce
Ranch
Tzatziki
Garlic aioli
Spicy yogurt dip
Air Fryer Method
For an air-fryer version:
Slice and salt the zucchini.
Pat very dry.
Add olive oil and Parmesan seasoning.
Arrange in a single layer.
Air fry at 375°F (190°C) for about 8–12 minutes.
Check frequently near the end because thin zucchini can brown quickly.
Cook in batches if necessary.
Low-Carb & Keto Option
For the lowest-carb version:
Use Parmesan only.
Skip regular breadcrumbs.
Avoid sweet dipping sauces.
Serve with ranch, garlic yogurt dip, or marinara with no added sugar.
Zucchini and Parmesan make a naturally low-carb combination. A Parmesan-only baked version is also described as low-carb by recipe sources.

Storage
These chips are best fresh from the oven.
Because zucchini contains a lot of water, they can soften during refrigeration.
If you have leftovers:

To crisp them again, bake at 350°F (175°C) for about 8–10 minutes.
Avoid reheating in the microwave if you want them crispy.
Q&A
Q: Why aren’t my zucchini chips crispy?
The most common reason is excess moisture. Salt the zucchini, allow it to release water, and pat the slices very dry before baking.
Q: Do I have to peel the zucchini?
No. The skin is completely fine to eat and helps the chips hold their shape.
Q: How thin should I slice the zucchini?
For very crispy chips, approximately â…› inch works well. Slightly thicker slices will have a softer center.
Q: Do I need to flip the zucchini?
Not necessarily. Some baked methods specifically recommend no flipping. Instead, arrange the slices in a single layer and monitor them as they brown.
Q: Can I use shredded Parmesan?
Finely grated Parmesan generally works better because it spreads more evenly and forms a crisp coating.
Q: Can I use mozzarella?
You can, but mozzarella contains more moisture and doesn’t crisp in the same way. Parmesan is better for crispy edges.
Q: Can I make these without breadcrumbs?
Yes! In fact, Parmesan-only zucchini chips are an excellent low-carb option.
Q: Can I use almond flour?
Yes, but almond flour contains tree nuts. It is not appropriate for someone with a tree-nut allergy.
Q: Can I make these dairy-free?
Yes, but you’ll need a dairy-free Parmesan-style cheese that melts and crisps well. Results will vary by product.
Q: Can I make them ahead?
You can slice and dry the zucchini ahead of time, but for the crispiest result, bake them shortly before serving.
Q: Can I freeze zucchini chips?
Freezing is not recommended because zucchini contains substantial moisture and the chips are likely to lose their crisp texture after thawing.
Q: What should I serve with them?
They’re delicious with marinara, ranch, tzatziki, garlic dip, or alongside grilled chicken, burgers, sandwiches, or salads.

Tips for Extra-Crispy Chips
Choose small, firm zucchini rather than very large watery ones.
Slice them evenly.
Salt and dry them thoroughly.
Don’t overcrowd the baking sheet.
Use finely grated Parmesan.
Bake at high heat.
Start checking the chips near the end because thin slices can brown quickly.
Let them cool for a few minutes before serving—the texture becomes crisper as they cool.
