Zucchini Parmesan Crisps
Zucchini Parmesan Crisps are a delightful and healthy snack or appetizer made from zucchini slices coated with Parmesan-based mixture.
Ingredients
- 2 small zucchinis
- 1/2 cup grated Parmesan cheese
- 1/2 cup breadcrumbs
- 1 tsp garlic powder
- 1/2 tsp dried oregano
- 1/4 tsp salt
- 1/4 tsp black pepper
- 1 egg (beaten)
- some olive oil
Instructions
Preheat your oven to 425°F (220°C). Line a baking sheet with parchment paper or lightly grease it to prevent sticking.
Slice the zucchinis into thin rounds, about 1/8 inch thick. Pat them dry with paper towels to remove excess moisture.
In a shallow dish or plate, combine the grated Parmesan cheese, breadcrumbs, garlic powder, dried oregano, salt, and black pepper. Mix everything together to create the coating mixture.
Dip each zucchini slice into the beaten egg, making sure both sides are coated. Press each egg-coated zucchini slice into the Parmesan and breadcrumb mixture, ensuring it is evenly coated on both sides.
Place the coated zucchini slices on the prepared baking sheet in a single layer, without overlapping. Drizzle some olive oil over the zucchini. Bake for about 15-20 minutes or until they turn golden and crispy. You may want to flip them halfway through baking for even crispiness on both sides.
Once they are done baking, remove the crisps from the oven and let them cool slightly before serving.

Zucchini Parmesan Crisps are a delightful and healthy snack or appetizer made from zucchini slices coated with Parmesan-based mixture.

What are Zucchini Parmesan Crisps made of?
Zucchini Parmesan Crisps are made of the following ingredients:
- Zucchini: Zucchini is the main star of this dish. It’s a summer squash with a mild and slightly sweet flavor. The zucchini is sliced into thin rounds, which form the base of the crisps. Zucchini is rich in multiple antioxidants, including lutein and zeaxanthin. Despite packing a punch with several important nutrients, zucchini is low in calories, fat, and sugar.
- Grated Parmesan Cheese: Parmesan cheese adds a rich and savory flavor to the crisps. It’s a hard, aged cheese known for its nutty and salty taste, which complements the zucchini beautifully.
- Breadcrumbs: Breadcrumbs provide a crunchy texture to the crisps. You can use either regular breadcrumbs or Panko, a type of Japanese breadcrumb known for its extra crispiness.
- Garlic Powder: Garlic powder enhances the overall flavor profile of the crisps with its mild garlic taste. It brings a subtle hint of garlic without overpowering the dish.
- Dried Oregano: Dried oregano is an aromatic herb that adds a pleasant and earthy taste to the crisps, further enhancing the Mediterranean flavors.
- Salt and Black Pepper: Salt and black pepper are common seasonings used to bring out the natural flavors of the zucchini and cheese, providing a well-balanced taste.
- Eggs: The beaten eggs act as a binding agent, helping the Parmesan and breadcrumb coating adhere to the zucchini slices.

How do you keep zucchini crisp when cooking?
To keep zucchini crisp when cooking, follow these tips:
- Use Fresh Zucchini: Start with fresh zucchini that is firm and not overly ripe. Older zucchini tends to be softer and may become mushy when cooked.
- Cut Uniformly: Slice or cut the zucchini into uniform pieces. This ensures even cooking and helps maintain the desired crispness.
- Don’t Overcook: Avoid overcooking the zucchini, as this can lead to a loss of crispness. Cook the zucchini until it is just tender and still has a slight bite.
- High Heat and Short Cooking Time: Cooking zucchini at high heat and for a short duration can help retain its crisp texture. Stir-frying or sautéing zucchini over high heat works well for maintaining its crispness.
- Avoid Crowding the Pan: If you’re cooking zucchini in batches, avoid overcrowding the pan. Overcrowding can lead to steaming rather than frying or sautéing, which can result in softer zucchini.
- Use Oil Sparingly: Use just enough oil to coat the zucchini when sautéing or stir-frying. Excess oil can make the zucchini greasy and less crispy.
- Preheat the Pan: Ensure your pan is properly preheated before adding the zucchini. A hot pan will help create a crispy exterior.
- Cook in Single Layer: When baking zucchini, arrange the slices in a single layer on the baking sheet. This allows the heat to evenly circulate around each piece, promoting crispness.
- Blot Excess Moisture: If your zucchini is particularly watery, you can blot the slices with a paper towel before cooking to remove excess moisture.
- Finish with High Heat: If you’re using a sauce or coating, finish cooking the zucchini with high heat for a short time to crisp up the surface.
By following these tips, you can ensure that your zucchini stays crisp and retains its delicious texture, whether you’re sautéing, stir-frying, baking, or using any other cooking method.

Substitutions & Variations
As a personal chef who specializes in dietary accommodations, I always encourage my clients to adapt recipes to their individual needs. Here are some practical variations for this recipe:
- Gluten-Free: Replace the breadcrumbs with certified gluten-free panko or almond flour for a similarly crispy coating. The rest of the recipe is naturally gluten-free.
- Dairy-Free: Swap the Parmesan for nutritional yeast or a plant-based Parmesan alternative. Nutritional yeast gives a wonderful savory, cheesy flavor and crisps up beautifully in the oven.
- Egg-Free: Replace each egg with a flax egg (1 tablespoon ground flaxseed mixed with 3 tablespoons water) or a commercial egg replacer. For binding purposes, mashed banana or unsweetened applesauce also work well.
Frequently Asked Questions
Why aren't my zucchini crisps getting crispy?
The most common culprits are excess moisture and overcrowding. Make sure to pat the zucchini slices completely dry before dipping in egg, slice them as thin and uniform as possible, and arrange them in a single layer with space between each piece. A higher oven temperature (425°F) and flipping halfway through also help achieve that satisfying crunch.
Can I air-fry these instead of baking?
Absolutely! Air-frying works beautifully and produces even crispier results. Arrange the coated slices in a single layer in the air fryer basket (no overlapping) and cook at 400°F for about 8–10 minutes, flipping halfway through. You may need to work in batches.
Can I use Panko instead of regular breadcrumbs?
Yes! Panko breadcrumbs are actually an excellent upgrade here — they produce an even lighter and crunchier coating than regular breadcrumbs. The larger, flakier texture creates more surface area for that golden crispiness we’re after.
How do I store and reheat leftover zucchini crisps?
Store leftovers in an airtight container in the refrigerator for up to 2 days. To reheat, spread them on a baking sheet and bake at 375°F for 5–7 minutes until crispy again. Avoid the microwave — it will make them soggy. Honestly, these are best enjoyed fresh from the oven.
