Preheat oven to 400F. Line a baking sheet with parchment paper.
Lay the asparagus evenly in one layer on the baking sheet.
Drizzle olive oil and sprinkle sea salt on asparagus.
Roast in the oven for 5-7 minutes or until asparagus is bright green. (Do not overcook. It should still have a crunch when removed from the oven.)
