Cut off the root ends of the asparagus and discard them.
Place the asparagus on the parchment paper and drizzle with 1 to 2 teaspoons olive oil, just enough to lightly coat the asparagus.
Sprinkle salt, pepper and garlic powder over the asparagus, and roll/toss until the spears are lightly coated in oil.
Arrange the spears in a single layer on the pan.
Roast until the asparagus ends are easily pierced with a fork. Thin asparagus may take 5-10 minutes and thicker asparagus may 15-20 minutes.
Remove from oven and top with sprinkled parmesan or the other toppings listed in the post above.
Notes
I have roasted asparagus drizzled with both olive oil and balsamic vinegar together. It has a zestier taste. Don't be afraid to try different flavors until you find your favorite! Enjoy!
