01 - Preheat oven to 425°F. Line a baking sheet with parchment paper.
02 - In a large bowl, toss Brussels sprouts with olive oil, salt, and pepper until evenly coated.
03 - Spread Brussels sprouts cut side down on the prepared baking sheet in a single layer.
04 - Roast for 20–25 minutes, stirring once halfway through, until golden brown and crispy at the edges.
05 - In a small saucepan over medium heat, combine balsamic vinegar and honey. Bring to a gentle boil, then reduce heat and simmer for 7–10 minutes, stirring occasionally, until reduced by half and syrupy.
06 - Transfer roasted Brussels sprouts to a serving platter. Drizzle with the balsamic glaze just before serving.
