1Preheat your oven to 400°F (200°C).
Slice the zucchinis into 1/4-inch thick rounds.
In a bowl, combine the breadcrumbs, grated Parmesan cheese, Italian seasoning, garlic powder, salt, and pepper.
Dip each zucchini slice into the olive oil, then coat with the breadcrumb mixture.
Place the coated zucchini slices on a baking sheet lined with parchment paper.
Bake in the preheated oven for 20 minutes, or until the zucchini is tender and the coating is golden brown.
Remove the zucchini from the oven and spoon marinara sauce over each slice.
Sprinkle shredded mozzarella cheese over the top.
Return to the oven and bake for an additional 5-7 minutes, or until the cheese is melted and bubbly.
Serve warm and enjoy your Baked Zucchini Parmesan.
