Preheat your oven to 425°F (220°C) and line a baking sheet with parchment paper or lightly grease it with cooking spray.

Wash the zucchinis and trim off the ends. Cut them into halves lengthwise, then slice each half into 1/2-inch thick pieces.

In a large mixing bowl, combine olive oil, minced garlic, dried oregano, paprika, salt, and black pepper. Mix well to create the seasoning blend.

Add the zucchini slices to the bowl and toss until they are evenly coated with the seasoning mixture.

Spread the seasoned zucchini slices in a single layer on the prepared baking sheet to ensure even cooking.

Sprinkle the grated Parmesan cheese evenly over the zucchini slices.

Place the baking sheet in the preheated oven and roast the zucchini for 15-18 minutes, or until they are tender and the Parmesan is golden and crisp.

For extra crispiness, broil the zucchini for an additional 2-3 minutes, keeping a close eye to prevent burning.

Remove the zucchini from the oven and let them cool for a minute. Optionally, garnish with chopped fresh parsley before serving.
