Preheat oven to 400 F.
In a large mixing bowl, combine zucchini, oil, thyme, garlic powder, salt, and pepper. Toss well until evenly coated.
Transfer the zucchini to a large baking sheet and spread evenly. Bake until tender and golden brown on the edges, about 25-30 minutes.
Sprinkle with parmesan cheese and drizzle with balsamic vinegar.
