Step 1

Preheat the oven to 350 degrees F (175 degrees C). Grease a baking dish or line a baking sheet with parchment paper.

Step 2

Combine zucchini slices and olive oil in a large bowl and toss to coat well.

Step 3

Mix Parmesan cheese, bread crumbs, oregano, salt, and pepper in a second bowl or shallow dish. Dip oiled zucchini into bread crumb mixture and arrange close together on the baking sheet.

Step 4

Bake in the preheated oven for 30 to 40 minutes, turning after 20 minutes so they brown evenly.
