Whether you’re serving them as a side, a snack, or a party nibble, they disappear fast. Make a batch and watch them vanish right off the tray.
Ingredients
Method
- Prep the zucchini. Wash and dry the zucchini well. Slice into thin, even rounds (about 1/8–1/4 inch). Thinner slices crisp more, but avoid paper-thin slices that burn quickly.
- Pat them dry. Lay slices on a clean towel and blot with paper towels. Removing surface moisture helps the coating stick and promotes crisping.
- Set up two bowls. In one bowl, beat the egg. In another, mix Parmesan, breadcrumbs, garlic powder, paprika, pepper, and salt.
- Coat the slices. Dip each zucchini round into the egg, let excess drip off, then press into the Parmesan-breadcrumb mix. Place coated slices on a parchment-lined baking sheet. Drizzle or lightly brush with 1 tablespoon olive oil.
- Bake option. Preheat the oven to 425°F (220°C). Bake for 12–16 minutes, flipping halfway. Add the remaining oil after flipping if needed. They’re done when golden brown and crisp at the edges.
- Air fryer option. Preheat to 400°F (200°C). Arrange chips in a single layer. Air fry 6–9 minutes, flipping halfway, until crisp and golden. Work in batches to avoid overcrowding.
- Season and serve. Sprinkle lightly with salt right out of the oven/air fryer. Serve warm with your favorite dip.
What Makes This Special
These chips deliver the crunch you want without deep frying. The mix of grated Parmesan and breadcrumbs creates a crisp, savory coating that clings to the zucchini.
A touch of garlic and paprika brings warmth and flavor without overpowering the vegetable. They’re also simple to customize, so you can keep them mild or kick them up with spice. Best of all, they’re oven-friendly and air fryer-friendly, so you can choose what works for you.
Ingredients
- 2 medium zucchini, sliced into 1/8–1/4 inch rounds

- 1/2 teaspoon garlic powder
- 1/2 teaspoon smoked paprika (or sweet paprika)
- 1/4 teaspoon black pepper
- 1/4 teaspoon kosher salt, plus more to finish

Keeping It Fresh
Zucchini chips are best the day they’re made. They start to soften as they sit, but you can keep leftovers in an airtight container in the fridge for up to 2 days. For the best texture, reheat them on a wire rack set over a baking sheet at 400°F (200°C) for 5–7 minutes, or in the air fryer for 2–3 minutes.
Avoid microwaving; it makes them soggy. If you’re prepping ahead, slice and dry the zucchini, mix your coating, and store separately, then assemble and bake just before serving.
Health Benefits
Zucchini is naturally low in calories and a good source of vitamins A and C, which support vision and immune health. It also provides fiber and water, helping you feel full without feeling heavy.
Using the oven or air fryer keeps added oil modest while still delivering that satisfying crunch. Parmesan adds protein and calcium, and a little goes a long way in flavor, so you don’t need much. If you swap regular breadcrumbs for whole-wheat or gluten-free versions, you can tailor these chips to your needs without sacrificing taste.
What Not to Do
- Don’t skip drying the zucchini. Excess moisture prevents crisping and makes the coating slide off.
- Don’t slice unevenly. Mixed thickness leads to some chips burning while others stay soft.
- Don’t overcrowd the pan or basket. Airflow is key to browning. Cook in batches if needed.
- Don’t rely on the microwave for reheating. It steams the coating and ruins the crunch.
- Don’t overdo the salt upfront. Parmesan is salty; taste before adding more at the end.
Variations You Can Try
- Herb lovers: Add 1 teaspoon dried Italian seasoning or mix chopped fresh parsley and basil into the coating after baking.
- Spicy kick: Stir in cayenne or red pepper flakes.
Serve with a chipotle yogurt dip.
- Lemon-pepper twist: Add 1 teaspoon lemon zest to the coating and finish with a squeeze of lemon.
- Gluten-free: Use gluten-free panko or crushed pork rinds instead of breadcrumbs.
- Low-carb: Skip breadcrumbs and use extra-fine almond flour mixed with Parmesan.
- Extra cheesy: Swap half the Parmesan for finely grated pecorino romano for a sharper flavor.
- Everything bagel: Mix 1 tablespoon everything bagel seasoning into the breadcrumb blend and serve with cream cheese dip.
FAQ
How do I get them extra crispy?
Pat the zucchini dry, slice evenly, and don’t crowd the pan. Use panko for added crunch and bake at a high temperature. A wire rack set over the baking sheet allows hot air to circulate and keeps the bottoms from steaming.
Can I make these without eggs?
Yes.
Brush the slices lightly with olive oil or use milk or buttermilk as the wet dip. You can also make a quick slurry with 2 tablespoons cornstarch and 3 tablespoons water to help the coating stick.
What’s the best dipping sauce?
Marinara, ranch, garlic aioli, and tzatziki are all great. For something lighter, try Greek yogurt mixed with lemon juice, grated garlic, and dill.
A splash of hot honey is fun if you like sweet-heat.
Can I use yellow squash instead of zucchini?
Absolutely. Yellow squash behaves similarly, though it can be a touch softer. Keep the slices on the thicker side and watch the timing to avoid overcooking.
Why did my coating fall off?
Usually it’s excess moisture or too much egg.
Dry the slices thoroughly and let the egg drip off before dredging. Press the coating on gently so it adheres, and avoid flipping too early.
How do I prevent soggy leftovers?
Store in a paper towel–lined container to absorb moisture. Reheat on a rack in a hot oven or air fryer.
If they still feel soft, give them an extra minute or two until the edges crisp.
Can I freeze zucchini chips?
Freezing isn’t ideal for already-cooked chips. Instead, you can bread the raw slices and freeze them in a single layer until solid, then bag them. Bake from frozen, adding a few extra minutes.
