01 - Preheat oven to 425°F. Line a large baking sheet with parchment paper for easy cleanup.
02 - Arrange asparagus in a single layer on the prepared baking sheet. Drizzle olive oil evenly over spears, then sprinkle with kosher salt and black pepper. Toss gently to coat all pieces.
03 - Place baking sheet in preheated oven and roast for 12–15 minutes until asparagus is tender-crisp and edges show slight caramelization. Shake the pan halfway through cooking for even browning.
04 - While asparagus roasts, combine balsamic vinegar and honey (or maple syrup) in a small saucepan. Bring to a gentle simmer over medium heat, stirring occasionally. Continue cooking until liquid reduces by half and reaches a syrupy consistency, approximately 5–7 minutes.
05 - Remove roasted asparagus from oven and transfer to a serving platter. Drizzle the warm balsamic glaze over the spears and serve immediately while hot.
