01 - Preheat the oven to 425°F. Line a baking sheet with parchment paper.
02 - Arrange the trimmed asparagus in a single layer on the baking sheet. Drizzle with olive oil, then sprinkle with salt and pepper. Toss gently to coat evenly.
03 - Roast in the preheated oven for 12–15 minutes, or until asparagus is tender and lightly browned, shaking the pan halfway through for even roasting.
04 - Place the balsamic vinegar and honey (or maple syrup) in a small saucepan over medium heat. Simmer, stirring occasionally, until reduced by half and slightly syrupy, about 8–10 minutes. Remove from heat and let cool slightly; it will thicken as it cools.
05 - Transfer the roasted asparagus to a serving platter. Drizzle with the balsamic reduction before serving.
