01 - Preheat oven to 425°F. Line baking sheet with parchment paper.
02 - Arrange trimmed asparagus in single layer on baking sheet. Drizzle with olive oil, sprinkle with salt and pepper, toss to coat evenly.
03 - Roast for 12-15 minutes until tender and slightly caramelized, shaking pan halfway through for even cooking.
04 - While asparagus roasts, combine balsamic vinegar and maple syrup in small saucepan over medium heat. Bring to gentle simmer, reduce heat to low. Simmer 6-8 minutes, stirring occasionally, until reduced by half and thickened to syrupy consistency. Remove from heat.
05 - Arrange roasted asparagus on serving platter. Drizzle with balsamic reduction. Garnish with pine nuts, shaved Parmesan, and extra pepper if desired. Serve immediately.
