Preheat the oven to 425°F.
Trim or break the woody ends of the asparagus. (This should be about 1 to 2 inches off the bottom.)
Place the asparagus on a large, rimmed baking sheet. Drizzle with the olive oil and sprinkle with the salt and pepper. Toss well to coat.
Roast for 9 to 12 minutes for thin to medium-width asparagus until the tips have crisped up and a paring knife inserts easily into the stalks. (For thicker pieces of asparagus, roast for 15 to 20 minutes.)
Drizzle the asparagus with lemon juice and toss to coat. Season with more salt and pepper to taste.
