01 - Preheat the oven to 425°F. Line a large baking sheet with parchment paper for easy cleanup.
02 - Place the trimmed asparagus and carrot sticks on the prepared baking sheet in a single, even layer to ensure uniform roasting.
03 - Drizzle the olive oil evenly over the vegetables. Sprinkle with sea salt, black pepper, garlic powder, and dried thyme. Toss gently to coat all pieces thoroughly.
04 - Roast in the preheated oven for 22-25 minutes, stirring halfway through cooking. The vegetables are done when tender and lightly caramelized at the edges.
05 - Transfer the roasted vegetables to a serving platter. Garnish with fresh parsley and lemon zest if desired. Serve immediately while hot for best flavor.
