Baked Parmesan Zucchini Chips taste cheesy, salty, and crisp around the edges with a tender center that feels like a lighter version of your favorite potato chip. They work perfectly for busy home cooks who want a 30-minute snack or side dish that still feels special on a weeknight. I first tested these during a football game and ended up ignoring the score because I kept “testing” the pan.

Ingredients You’ll Need

Zucchini

2 medium zucchini, about 1 pound total, sliced into 1/8 to 1/4 inch rounds
- Smaller, thinner zucchini give the best texture and less water.
- Pat them dry with paper towels to help them crisp.

Cheesy coating

1 cup finely grated Parmesan cheese
- Use the dry, sandy kind from a wedge or a good pre-grated tub.
- Avoid the green can style for this recipe, since it clumps and browns too fast.
1/3 cup plain breadcrumbs or panko
- Panko gives extra crunch.
- Use gluten free breadcrumbs if needed.
2 tablespoons cornstarch or fine rice flour
- This helps absorb moisture and adds crispness.
- Cornstarch from any basic brand works well.
1 teaspoon garlic powder
1 teaspoon onion powder
1 teaspoon Italian seasoning or a mix of dried oregano and basil
1/2 teaspoon smoked or sweet paprika
1/2 teaspoon fine sea salt, plus more to taste
1/4 teaspoon black pepper

Wet mixture

2 large egg whites (or 1 whole egg if you prefer)
1 tablespoon olive oil
1 teaspoon Dijon mustard (optional, but it adds nice flavor and helps coating stick)

Optional toppings and dips

Extra grated Parmesan for sprinkling
Chopped fresh parsley or basil
Marinara sauce, ranch, garlic yogurt dip, or hummus for serving

Equipment

Large baking sheet
Parchment paper or a silicone baking mat
Two medium bowls
Whisk or fork
Sharp knife or mandoline for even slices
Cooling rack (optional, but it helps chips stay crisp)

Tips & Tricks

Slice zucchini evenly so all chips cook at the same rate.
Go slightly thicker than paper thin or they burn before they crisp.
Pat zucchini slices very dry with paper towels to reduce sogginess.
Use finely grated Parmesan so it melts and sticks instead of falling off.
Mix Parmesan and breadcrumbs thoroughly so each chip gets an even coating.
Line the baking sheet with parchment to prevent sticking and help browning.
Do not crowd the pan; leave a little space between slices for airflow.
Flip chips halfway through baking to brown both sides.
Rotate the pan if your oven heats unevenly.
Taste one chip near the end and adjust salt on the rest while they are hot.
Serve chips right away for the best crunch.
If you want extra crisp edges, broil for 1 to 2 minutes at the end and watch closely.

How to Make Baked Parmesan Zucchini Chips

Prep the zucchini

Preheat the oven to 425°F and line a large baking sheet with parchment paper.
Wash the zucchini, trim the ends, and slice into 1/8 to 1/4 inch rounds.
Lay slices on a clean towel or paper towels and pat both sides dry.

Mix the coating

In a medium bowl, whisk egg whites, olive oil, and Dijon mustard until frothy.
In another bowl, combine Parmesan, breadcrumbs, cornstarch, garlic powder, onion powder, Italian seasoning, paprika, salt, and pepper.
Stir the dry mixture until everything looks evenly combined.

Coat the zucchini

Drop a handful of zucchini slices into the egg mixture and toss to coat.
Lift slices out, let excess drip off, and place them into the Parmesan breadcrumb bowl.
Toss gently so each slice picks up a generous coating, then set coated slices on the prepared baking sheet.
Repeat with remaining zucchini, keeping slices in a single layer without overlapping.

Bake until crisp

Place the baking sheet on the middle rack and bake for 10 to 12 minutes.
Flip each chip carefully with tongs or a spatula.
Bake another 8 to 10 minutes, until the edges look deep golden and the centers feel set, not soggy.
If you want extra color, switch to broil for 1 to 2 minutes and watch closely so they do not burn.

Finish and serve

Transfer chips to a cooling rack or a plate lined with paper towels.
Sprinkle with a little extra Parmesan and chopped herbs while still hot.
Serve Baked Parmesan Zucchini Chips right away with your favorite dip.

What to Serve with Baked Parmesan Zucchini Chips

Serve Baked Parmesan Zucchini Chips with a bowl of marinara sauce, ranch, or a simple Greek yogurt dip with garlic and lemon. They pair nicely with grilled chicken, turkey burgers, or a big salad for a lighter meal. Kids like them next to baked fish sticks or grilled cheese sandwiches. You can also set them out as a snack with fresh fruit and cut veggies for a fun, colorful platter.
