Preheat your oven to 450°F
Wash and dry the asparagus and trim off the tough ends.
Spread the asparagus on a large baking sheet, and drizzle them with the olive oil.
Sprinkle with the salt, pepper, and half of the Parmesan cheese.
Using your hands, toss the asparagus until they're evenly coated, and spread them back out on the pan.
Place the pan on the middle rack of the oven, and cook for 5 minutes.
After 5 minutes, rotate the pan and cook for another 3 to 5 minutes or until they're cooked to your liking.
Sprinkle with the remaining Parmesan cheese, and cook for another 30 to 60 seconds or until the cheese is just melted.
Sprinkle on some fresh, chopped Italian parsley before serving.
Serve immediately or store in the refrigerator for up to three days.
