Ingredients

Scale
  • 3 medium zucchini, sliced into 1/4-inch rounds
  • 1 large egg, lightly beaten
  • 1/4 cup all-purpose flour (or gluten-free alternative)
  • 1/2 cup grated Parmesan cheese, finely grated
  • 1/4 cup panko breadcrumbs (optional, for extra crispiness)
  • 1 teaspoon garlic powder
  • 1/2 teaspoon dried oregano
  • 1/4 teaspoon salt
  • 1/8 teaspoon black pepper
  • Cooking spray or 1 tablespoon olive oil

Instructions

  1. Preheat your oven to 400°F (200°C). Line a large baking sheet with parchment paper or a silicone mat. Lightly spray the paper with cooking spray.
  2. Prepare the zucchini: Slice the zucchini into uniform 1/4-inch rounds. Pat the slices completely dry using paper towels. This step is crucial to prevent soggy zucchini.
  3. Set up a dredging station with three shallow bowls. In the first bowl, place the flour. In the second bowl, place the beaten egg. In the third bowl, combine the grated Parmesan cheese, panko breadcrumbs (if using), garlic powder, oregano, salt, and pepper.
  4. Coat the zucchini: Dip each zucchini slice first into the flour, shaking off any excess. Next, dip it into the egg mixture, letting excess drip off. Finally, press the slice firmly into the Parmesan mixture to create an even coating.
  5. Arrange the coated zucchini slices in a single layer on the prepared baking sheet. Do not overlap them.
  6. Lightly spray the tops of the coated zucchini with cooking spray or drizzle with olive oil. This helps the coating brown and crisp up.
  7. Bake for 12 to 15 minutes, flipping the slices halfway through. Continue baking until the coating is golden brown and crispy, and the zucchini is tender.
  8. Serve immediately as a healthy Parmesan side dish or appetizer.

Notes

  • For the crispiest results, ensure your zucchini slices are very dry before coating.
  • If you want a lower-carb option, skip the panko breadcrumbs and use only extra Parmesan cheese in the coating mixture.
  • This recipe works well as an air fryer zucchini substitute; cook at 380°F for 8-10 minutes, shaking halfway.
