Preheat oven to 425°F (220°C). Line a baking sheet with parchment paper.
Wash and slice zucchini into rounds or spears.
Place zucchini in a large bowl.
Add olive oil, garlic, Parmesan cheese, Italian seasoning, paprika, salt, and pepper. Toss well to coat evenly.
Arrange zucchini in a single layer on the prepared baking sheet.
Roast for 18–22 minutes until tender and golden brown.
For extra crispiness, broil for 1–2 minutes at the end if desired.
Remove from oven and garnish with parsley, lemon juice, or extra Parmesan cheese before serving.
