Pre-heat the oven to 400°F.
Pick up one stalk of asparagus and hold it in the middle and at the end.
Bend the stalk until it snaps.
Line up the tip of that stalk with the tips of the remaining stalks.
Slice off the ends of the remaining stalks so they are flush with the snapped stalk.
Line the asparagus on a baking sheet and brush with melted butter.
Sprinkle evenly with salt, pepper and garlic powder.
Transfer to the pre-heated oven and bake for 12 to 14 minutes.
While the asparagus is roasting, using a small saucepan, whisk together the balsamic vinegar, minced garlic and brown sugar.
Bring to a low simmer for about 5 to 10 minutes until the balsamic vinegar thickens to a glaze; stirring occasionally.
Remove from the heat; set aside.
Remove the asparagus from the oven and drizzle with the balsamic glaze.
