Preheat your oven to 425°F (220°C).
In a large bowl, toss the zucchini rounds with olive oil, salt, black pepper, and Italian seasoning until evenly coated.
Spread the zucchini in a single layer on a baking sheet.
Roast in the preheated oven for about 15-20 minutes, or until the zucchini is tender and slightly golden.
Remove from the oven and sprinkle the grated Parmesan cheese evenly over the zucchini.
Return to the oven for an additional 2-3 minutes, until the cheese is melted and bubbly.
Serve immediately and enjoy!
