Ingredients

2 medium zucchinis, sliced into ¼-inch thick rounds
½ cup grated Parmesan cheese
½ cup breadcrumbs (preferably panko for extra crunch) or finely ground oats
1 teaspoon dried oregano
½ teaspoon garlic powder
½ teaspoon onion powder
½ teaspoon salt
¼ teaspoon black pepper
1–2 tablespoons olive oil (or cooking spray)
1 large egg (for coating)
2 tablespoons milk (optional, for egg wash)

Step-by-Step Instructions

Step 1: Prepare the Zucchini

Start by washing the zucchinis thoroughly under cool running water. Pat them dry with paper towels.

Slice them into evenly sized rounds, about ¼-inch thick. Try to keep the slices uniform so they cook evenly.

If your zucchini seems watery, sprinkle the slices lightly with salt and let them sit for 15–20 minutes. This helps draw out excess moisture. Afterward, gently pat them dry with paper towels. Removing moisture is key to achieving a crispy result.

Step 2: Prepare the Coating Mixture

In a medium bowl, combine:

Grated Parmesan cheese
Breadcrumbs (or finely ground oats)
Dried oregano
Garlic powder
Onion powder
Salt
Black pepper

Mix thoroughly so all seasonings are evenly distributed.

In a separate small bowl, whisk together the egg and milk until smooth. This will help the coating stick to the zucchini slices.

Step 3: Coat the Zucchini

Dip each zucchini round into the egg mixture, making sure it’s fully coated.

Then press it into the Parmesan-breadcrumb mixture. Lightly press to help the coating stick well on both sides.

Place coated slices on a plate or baking sheet while you finish coating the rest.

For extra crunch, you can double coat:

Dip back into egg
Then again into breadcrumb mixture

Baking Method (Healthiest Option)

Step 4: Preheat the Oven

Preheat your oven to 425°F (220°C). Line a baking sheet with parchment paper or lightly grease it with olive oil.

Step 5: Arrange the Zucchini

Place the coated zucchini rounds in a single layer on the baking sheet. Make sure they are not overlapping. Overcrowding can make them soggy instead of crispy.

Lightly drizzle or spray olive oil over the tops. This helps them brown beautifully.

Step 6: Bake

Bake for 18–22 minutes, flipping halfway through cooking time.

For extra crispiness, turn on the broiler for the last 2–3 minutes. Watch carefully to avoid burning.

They are done when:

The coating is golden brown
The zucchini is tender inside
The edges are crispy

Air Fryer Method (Extra Crispy)

Preheat air fryer to 400°F (200°C).

Place zucchini rounds in a single layer in the basket. Cook for 8–10 minutes, flipping halfway through.

Do not overcrowd the basket. Cook in batches if needed.

The air fryer gives an even crispier texture with less oil.

Pan-Frying Method (Traditional Crispy Style)

Heat 2–3 tablespoons of olive oil in a skillet over medium heat.

Add zucchini rounds in a single layer. Cook 2–3 minutes per side until golden brown.

Transfer to paper towels to drain excess oil.

Storage and Reheating

Why This Recipe Works

The combination of Parmesan and breadcrumbs creates a crispy crust. The egg wash helps bind the coating, while high heat ensures proper browning. Removing excess moisture prevents sogginess, which is the key to perfect zucchini rounds.

The balance of herbs and spices enhances the mild flavor of zucchini without overpowering it.
