Toss with Oil and Seasoning: Place the asparagus on a baking sheet. Drizzle with olive oil and toss gently to coat. Sprinkle generously with salt and freshly ground black pepper.
Roast:Spread the asparagus in a single layer on the baking sheet. Roast in the preheated oven for 10-15 minutes, or until the asparagus is tender-crisp and slightly browned. The exact cooking time will depend on the thickness of your asparagus spears.
Serve: Transfer the roasted asparagus to a serving dish. Squeeze fresh lemon juice over the top, if desired. Serve immediately.
