Slice the zucchini into evenly sized slices. The thickness is really a personal preference, but I usually go somewhere between 1/4″ to 1/2″.
Place the panko crumbs in a bowl. Add the Parmesan, salt, and pepper, along with the oregano, Italian seasoning, garlic powder, and red pepper flakes if using.
Crack the eggs into a separate bowl. Use a fork to break the yolks and mix together the yolks and whites like you’re going to make scrambled eggs. (Just don’t cook them yet!)
Place the flour in a third bowl.
Dip a zucchini slice in the flour and shake off the excess flour. Next, dip the zucchini slice in the egg mixture and shake off excess egg.
Add zucchini slice to a shallow bowl filled with parmesan and panko mixture. Using a small spoon, cover the top of the zucchini in bread crumbs/parmesan. Flip over and press to coat both sides evenly in the panko mixture.
Place the zucchini slice on a tray. Repeat this process with remaining zucchini slices.
Add coated slices to your air fryer basket in a single layer. If your air fryer model didn’t come with a basket (mine doesn’t), you may have to transfer them to a baking sheet that will fit in your air fryer before placing them in the air fryer.
Lightly spray with a nonstick cooking oil spray. Flip over and spray the other side.
Cook at 375 degrees for 6 minutes. Flip over and cook for an additional 5 minutes or until golden brown on both sides.
Serve breaded zucchini slices promptly with a selection of dips. I like garlic aioli, marinara, and ranch sauce.
