Preheat oven to 400 degrees F. Coat a cooling rack with nonstick spray and place on a baking sheet; set aside.
In a small bowl, combine Parmesan, thyme, oregano, basil, garlic powder, salt and pepper, to taste.
Place zucchini onto the prepared baking sheet. Drizzle with olive oil and sprinkle with Parmesan mixture in an even layer.
Place into oven and bake until tender, about 10-15 minutes, flipping halfway. Then broil for 2-3 minutes, or until crisp and golden brown.
Serve immediately, garnished with parsley, if desired.
Notes
Dry thoroughly. Zucchini has a very high water content. Pat the zucchini dry with paper towels before baking to guarantee that crispy exterior.
Cut into uniform pieces. Cut the zucchini into similar-sized sticks to ensure even cooking and browning.
Freshly grated Parmesan goes a long way. Pre-shredded cheese contains anti-caking agents, burning easily and leaving a meal crust. Use freshly grated cheese for that crispy, golden, flavorful crust.
Use a cooling rack on a baking sheet. No more soggy limp zucchini! Baking the zucchini directly on an oven-safe cooling rack inside a baking sheet will prevent steaming and provide even airflow with easy clean up.
Don't overcrowd the pan. Space the zucchini sticks out in a single, even layer, about 1/2-inch, for proper browning. When the pan is crowded, the steam will get trapped between the sticks, causing the zucchini to steam instead.
Make it in the air fryer. These can easily be cooked in the air fryer at 400°F for 8-10 minutes, shaking halfway through.
Reheat in the oven. Leftover zucchini sticks can become mushy when reheated in the microwave. For best results with leftovers, reheat in the oven (to regain some of its crispness) at 375°F until warmed through.
