Preheat oven to 425 degrees. Coat a baking sheet with olive oil cooking spray.
Prepare the asparagus by snapping the woody ends off of each spear. Arrange the asparagus in a single layer on the prepared baking sheet. Drizzle with olive oil and season with sea salt and freshly cracked pepper, to taste.
Roast the asparagus by placing the baking sheet into the oven and roasting until crisp-tender, about 10 minutes.
Make the brown butter while the asparagus is in the oven, by heating a small saucepan over medium heat. Add the butter and cook, stirring constantly, until it melts, froths up, and begins to golden in color. Take off the heat; add the garlic and stir quickly. Return to the heat for another minute or two, while stirring, until the butter reaches a dark amber color. Remove from heat; add lemon juice and stir to combine. Pour into a serving dish.
To serve, place asparagus spears on a serving plate and sprinkle with parmesan cheese. Drizzle browned butter over the asparagus. Enjoy.
