Preheat your oven to 425°F (220°C). Line a large baking sheet with parchment paper or aluminum foil for easy cleanup.
Wash the zucchinis thoroughly and pat them dry. Trim the ends, then cut each zucchini into quarters lengthwise to create spears.
Arrange the zucchini on your prepared baking sheet, skin side down so the topping can crisp up during baking.
In a small bowl, mix together the grated Parmesan, thyme, oregano, basil, rosemary, garlic powder, and a pinch each of salt and pepper.
Sprinkle the Parmesan-herb mixture evenly over the top of the zucchini spears, pressing it gently to help it stick.
Drizzle just a bit of olive oil over the coated zucchini. This helps the topping crisp up and adds a gorgeous golden color.
Bake for 15-18 minutes, or until the zucchini is tender and the cheese topping is golden and crispy.
Remove from the oven and serve immediately, garnished with a sprinkle of extra Parmesan or fresh herbs if desired.
