01 - Preheat the oven to 425°F and line a baking sheet with parchment paper.
02 - Toss the halved Brussels sprouts with olive oil, salt, and pepper in a large bowl until evenly coated.
03 - Spread the Brussels sprouts cut side down on the prepared baking sheet.
04 - Roast for 20 to 25 minutes, stirring once halfway through, until the sprouts are golden brown and crisp on the edges.
05 - While the sprouts roast, combine the balsamic vinegar and honey in a small saucepan over medium heat. Simmer for 5 to 6 minutes, stirring occasionally, until reduced by half and thickened into a glaze. Remove from heat.
06 - Transfer roasted Brussels sprouts to a serving platter. Drizzle with the balsamic glaze and toss gently to coat. Serve immediately.
