Preheat oven to 400 degrees F.
Break or cut off the woody ends of the asparagus spears.
In a large bowl, add the olive oil, garlic, salt, pepper, and asparagus. Toss to coat.
Spread the asparagus spears on a large baking sheet and sprinkle with the Parmesan cheese.
Bake 15 to 20 minutes, or until the spears begin to brown, turning once.
