1. **Preheat the Oven:** Start by preheating your oven to 400°F (200°C).
2. **Prepare the Asparagus:** Rinse the asparagus spears under cold water and pat them dry with a paper towel. Trim off the tough, woody ends of the asparagus. You can do this by snapping off the ends where they naturally break, or by cutting off about 1-2 inches from the bottom.
3. **Season the Asparagus:** Place the trimmed asparagus spears on a baking sheet in a single layer. Drizzle the asparagus with olive oil and season with salt and pepper, or any other desired seasonings or herbs.
4. **Roast the Asparagus:** Place the baking sheet in the preheated oven and roast the asparagus for about 12-15 minutes, or until the spears are tender and slightly browned. The cooking time may vary depending on the thickness of the asparagus spears, so keep an eye on them to avoid overcooking.
5. **Serve:** Once the asparagus is roasted to your liking, remove it from the oven and transfer it to a serving dish. You can squeeze a little lemon juice over the roasted asparagus before serving for added brightness, if desired.
