01 - Preheat the oven to 425°F. Line a baking sheet with parchment paper or foil.
02 - Arrange the trimmed asparagus in a single layer on the prepared baking sheet. Drizzle with olive oil, then sprinkle with kosher salt and freshly ground black pepper. Toss to coat evenly.
03 - Roast the asparagus for 12 to 15 minutes, or until tender and lightly browned, shaking the pan halfway through cooking to ensure even roasting.
04 - Remove from oven and immediately sprinkle with grated Parmesan cheese and lemon zest. Drizzle with fresh lemon juice.
05 - Serve the asparagus warm, optionally garnished with additional Parmesan or lemon wedges.
