Creating Crispy Baked Zucchini Chips is simple and requires just a few steps. Follow this guide for the best results:

1. Preheat Oven: Preheat your oven to 225°F (107°C). Line a baking sheet with parchment paper for easy cleanup.
2. Slice Zucchini: Wash the zucchinis and slice them thinly, about 1/8 inch thick. Consistent thickness ensures even cooking.
3. Remove Moisture: Pat the zucchini slices dry with paper towels to remove excess moisture. This step is crucial for achieving crispiness.
4. Prepare Breading Station: In one bowl, whisk the eggs. In another bowl, combine breadcrumbs, Parmesan cheese, garlic powder, onion powder, salt, and pepper.
5. Coat Zucchini Slices: Dip each zucchini slice in the egg mixture, allowing the excess to drip off. Then, coat it in the breadcrumb mixture, pressing gently to adhere.
6. Arrange on Baking Sheet: Place the coated zucchini slices in a single layer on the prepared baking sheet, ensuring they are not touching.
7. Spray with Oil: Lightly spray the tops of the zucchini chips with cooking spray or drizzle with olive oil for added crunch.
8. Bake: Bake in the preheated oven for 2 hours, flipping the zucchini slices halfway through to ensure even cooking.
9. Cool and Crisp: Once the chips are golden and crispy, remove them from the oven and let them cool for a few minutes. They will continue to crisp up as they cool.
10. Store or Serve: Enjoy immediately or store in an airtight container once completely cooled.
