Preheat the oven to 425F and line a large baking sheet with parchment paper.
Rinse the asparagus under warm water and pat them dry with a clean kitchen towel. Remove the woody ends with a sharp knife, or break them off by hand, usually about 2″ from the bottom.
Season:
Place the asparagus spears onto the baking sheet, drizzle with olive oil, put the garlic or garlic powder on top, and season with salt, and black pepper. Toss the spears around to coat with the seasonings an garlic.
Roast:
Roast in the preheated for 12 to 15 minutes or until the tops are golden brown and the middle of the spear is tender when poked with a fork. I recommend checking for doneness around the 12-minute mark.
Remove the baking sheet from the oven and sprinkle the Parmesan cheese over the spears.
Place the baking sheet back into the oven and allow the cheese to melt, for about 1 minute.
Notes
If you only have grated Parmesan, the one with the powder-like texture, use that. It will work too!
