Ingredients

For the Zucchini Chips:

4 medium zucchini

1 tablespoon olive oil

1 cup finely grated Parmesan cheese

1 teaspoon garlic powder

1 teaspoon Italian seasoning

½ teaspoon paprika

¼ teaspoon black pepper

¼ teaspoon salt, or to taste

Optional: ¼ teaspoon onion powder

Optional: 1 tablespoon finely chopped fresh parsley for serving

Optional: red pepper flakes for a little heat

Instructions

1. Prepare the Oven

Preheat your oven to 425°F (220°C).

Line a large baking sheet with parchment paper. For the crispiest result, you can also place a wire rack over the baking sheet and arrange the zucchini slices on the rack. This allows hot air to circulate underneath the zucchini.

If you are using parchment paper, lightly spray or brush it with olive oil to help prevent sticking.

2. Slice the Zucchini

Wash and dry the zucchini thoroughly.

Using a sharp knife or mandoline slicer, cut the zucchini into very thin, even slices. Aim for approximately ⅛-inch slices.

Try to keep the slices as uniform as possible. Thin slices become crispier, while thicker slices will remain softer in the center.

After slicing, gently pat the zucchini dry with paper towels.

This step is important because zucchini naturally contains a lot of water. Removing some surface moisture helps the chips brown instead of steaming in the oven.

3. Make the Parmesan Seasoning

In a medium bowl, combine the finely grated Parmesan cheese, garlic powder, Italian seasoning, paprika, black pepper, and salt.

Mix everything thoroughly so the seasonings are evenly distributed throughout the Parmesan.

Because Parmesan is naturally salty, use only a small amount of additional salt. You can always add more after baking if needed.

4. Coat the Zucchini

Place the zucchini slices in a bowl and drizzle them with olive oil.

Gently toss until each slice has a very light coating of oil.

Next, add the Parmesan seasoning mixture and gently toss again.

You don’t need a thick coating. A light layer of Parmesan on each slice is enough to create a golden, cheesy crust.

For an especially crisp result, you can press a little of the Parmesan mixture onto the surface of each zucchini slice before placing it on the baking sheet.

5. Arrange the Slices

Arrange the zucchini slices in a single layer on the prepared baking sheet.

Do not overlap the slices.

Leave a little space between them whenever possible. Crowding the pan can trap steam and prevent the zucchini from becoming crispy.

If you have a large amount of zucchini, use two baking sheets rather than putting everything onto one crowded tray.

6. Bake

Place the baking sheet in the preheated oven.

Bake for approximately 25–35 minutes, depending on the thickness of your zucchini slices and your oven.

After about 15–20 minutes, begin checking the chips regularly.

The Parmesan should become golden brown, and the edges should look crisp.

If some slices are browning faster than others, rotate the baking sheet or remove the finished pieces while allowing the thicker slices to continue baking.

7. Cool Briefly

Remove the zucchini chips from the oven once they are golden and crisp around the edges.

Allow them to cool on the baking sheet for approximately 3–5 minutes.

They will continue to firm up slightly as they cool.

For the crispiest texture, transfer them to a wire rack rather than leaving them directly on the hot baking sheet.

8. Serve

Serve the Baked Parmesan Zucchini Chips warm.

For extra flavor, sprinkle them with fresh parsley, additional Parmesan, or a small pinch of red pepper flakes.

They are delicious on their own or served with marinara sauce, Greek yogurt dip, ranch-style dip, garlic yogurt sauce, or your favorite low-carb dipping sauce.

Description

These Baked Parmesan Zucchini Chips are thin, crispy, cheesy, and packed with savory flavor. Fresh zucchini is sliced thinly, lightly coated with olive oil, seasoned with garlic, Italian herbs, paprika, and black pepper, then finished with Parmesan cheese before being baked until golden.

The result is a delicious snack with crispy, browned edges and a tender center. They make an easy side dish for dinner but are also perfect for casual snacking.

Unlike deep-fried vegetable chips, these zucchini chips are baked in the oven with only a small amount of olive oil. They are an easy way to add more vegetables to your meal while still enjoying a crunchy, cheesy bite.

Notes

Zucchini contains a lot of water, so don’t skip the drying step. Patting the slices dry before adding the oil and Parmesan can make a noticeable difference in the final texture.

Freshly grated Parmesan generally works particularly well because it melts and browns beautifully.

For the crispiest chips, slice the zucchini as thinly and evenly as possible.

Keep an eye on the chips toward the end of baking because the Parmesan can go from golden to overly dark fairly quickly.

The exact baking time will vary depending on the thickness of the zucchini slices, the amount of moisture in the zucchini, and the performance of your oven.

If your zucchini is particularly large and watery, you can lightly sprinkle the slices with salt and let them sit for 10 minutes. Pat away the moisture before continuing with the recipe.

Tips for Extra-Crispy Zucchini Chips

Slice Them Thin

Thin zucchini slices have the best chance of becoming crisp. A mandoline slicer can help create consistent slices, but always use caution when handling it.

Don’t Overcrowd the Pan

Give each slice room. If zucchini slices overlap, they will release moisture into one another and are more likely to become soft.

Dry the Zucchini

This is one of the most important steps. Use paper towels to remove excess moisture from the sliced zucchini before adding oil and Parmesan.

Use Finely Grated Parmesan.

Finely grated Parmesan adheres well to the zucchini and creates a delicious golden crust.

Watch the Final Minutes

The chips can brown quickly near the end of cooking. Start checking them regularly during the last 5–10 minutes.

Use a Wire Rack

If you have one, baking the zucchini on a wire rack placed over a baking sheet can help air circulate around the slices and encourage more even crisping.

Let Them Cool

Don’t worry if the zucchini seems slightly soft when it first comes out of the oven. The chips can become firmer as they cool.

Flavor Variations

Garlic Parmesan

Increase the garlic powder slightly and finish the chips with fresh minced parsley.

Spicy Parmesan

Add red pepper flakes or a small pinch of cayenne pepper to the Parmesan mixture.

Lemon Herb

Add a little lemon zest to the finished chips and garnish with fresh parsley.

Italian Style

Use Italian seasoning, garlic powder, Parmesan, and a pinch of dried oregano.

Cheesy Herb

Mix Parmesan with a small amount of finely grated mozzarella and dried herbs. Watch carefully because mozzarella can brown faster.

Serving Suggestions

These zucchini chips can be served as an appetizer, snack, or side dish.

Pair them with grilled chicken and a fresh salad for a simple dinner.

Serve them beside baked fish, roasted salmon, or shrimp for a light meal.

They are also delicious with burgers or sandwiches when you want a crunchy vegetable side instead of traditional fries.

For entertaining, arrange the chips on a platter and serve them with a bowl of marinara or garlic yogurt dip.

They are best enjoyed fresh from the oven when the Parmesan is warm and crisp.

Storage

For the best texture, eat these zucchini chips shortly after baking.

If you have leftovers, allow them to cool completely and store them in an airtight container in the refrigerator for up to 2–3 days.

Keep in mind that refrigerated zucchini chips will soften because of the moisture in the vegetable.

To bring back some of their crispness, reheat them in an oven or air fryer rather than a microwave.

Reheat at approximately 375°F (190°C) until warmed through and lightly crisp.

Can You Make Them in an Air Fryer?

Yes. Air frying is another excellent option for zucchini chips.

Arrange the zucchini slices in a single layer in the air-fryer basket. Avoid overcrowding.

Air fry at approximately 375°F (190°C) for 8–12 minutes, checking frequently toward the end.

The exact time will depend on your air fryer and the thickness of the zucchini slices.

Servings

This recipe makes approximately 4 servings.

Serving size: about one-quarter of the recipe.

The exact number of chips per serving will depend on the size of your zucchini and how thinly you slice them.

Frequently Asked Questions

Can I use yellow squash instead of zucchini?

Yes. Yellow summer squash can be substituted for zucchini. Choose firm squash and slice it thinly and evenly.

Why are my zucchini chips soggy?

The most common reasons are excess moisture, slices that are too thick, or overcrowding the baking sheet. Pat the zucchini dry, slice it thinly, and arrange the pieces in a single layer.

Can I make these without olive oil?

A small amount of oil helps the Parmesan brown and helps the seasoning adhere to the zucchini. You can reduce the amount, but completely eliminating it may affect the texture and browning.

Can I use pre-shredded Parmesan?

You can, but finely grated Parmesan tends to create a more even coating. Freshly grated Parmesan is often preferable for this recipe.

Can I make these dairy-free?

Yes, but the Parmesan would need to be replaced with a suitable dairy-free Parmesan-style alternative. The flavor and texture will vary depending on the product used.

Are these keto-friendly?

They can fit into many keto-style meal plans because zucchini is relatively low in carbohydrates. However, the exact carbohydrate content depends on the ingredients and serving size.

Can I prepare the zucchini ahead of time?

You can slice and dry the zucchini a short time ahead, but for the best results, coat and bake it relatively close to serving time.

Why did my Parmesan stick to the pan?

Parmesan can stick as it melts and browns. Parchment paper or a lightly greased baking surface can make removal easier. Allowing the chips to cool for a few minutes before lifting them can also help.

Can I make thicker chips?

Yes, but thicker slices will be softer in the center and may require additional baking time. For a chip-like texture, thin slices are recommended.

What can I serve with zucchini chips?

Try marinara sauce, ranch-style dip, garlic yogurt dip, tzatziki, hummus, or a simple lemon-herb yogurt sauce.
