01 - Preheat oven to 425°F. Line a baking sheet with parchment paper.
02 - Arrange trimmed asparagus in a single layer on prepared 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 the pan halfway through for even cooking.
04 - Combine balsamic vinegar and maple syrup (or honey) in small saucepan over medium heat. Bring to gentle simmer, reduce heat to low, and simmer 6–8 minutes until reduced by half and thickened to syrupy consistency. Remove from heat and cool slightly.
05 - Arrange roasted asparagus on serving platter. Drizzle with balsamic reduction. Garnish with pine nuts, shaved Parmesan, and extra pepper if desired. Serve immediately.
