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