01 - Preheat oven to 425°F. Line a rimmed baking sheet with parchment paper.
02 - Spread trimmed asparagus in a single layer on the prepared sheet. Drizzle with olive oil, season with salt and pepper, and toss to coat evenly.
03 - Roast 12 to 15 minutes until spears are tender and lightly caramelized at the tips.
04 - While asparagus roasts, combine balsamic vinegar and maple syrup in a small saucepan. Bring to a boil over medium heat, then reduce to a simmer and cook 4 to 5 minutes, stirring occasionally, until reduced by half and syrupy.
05 - Transfer roasted asparagus to a serving platter. Drizzle glaze evenly over the top and serve immediately.
