Instructions

1. Preheat your oven to 400°F. Rinse the asparagus spears using the method in the post.  If the ends are tough, cut them off and either discard or save for stock. Dry spears or let them air dry.
2. Arrange the asparagus spears in a single layer on a roasting pan. Drizzle with olive oil, then sprinkle with salt and pepper.
3. Toss to combine, thoroughly.
4. Roast at 425°F for 10 minutes, then toss them on the pan so the underside flips to the top. Continue roasting, another 5-10 minutes, more or less, depending on your particular oven and how thick the spears are, until the asparagus are lightly browned and tender when you pierce them with a fork. (Optional - Turn your oven to broil the last 1-2 minutes of cooking for optimal browning but stay close so the asparagus doesn't burn.) 
5. (Optional) Drizzle with fresh lemon juice.
