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, sea salt, and black pepper until evenly coated.
03 - Spread Brussels sprouts cut-side down in a single layer on the prepared baking sheet.
04 - Roast for 20 to 25 minutes, stirring once halfway through, until golden brown and crisp at the edges.
05 - Meanwhile, combine balsamic vinegar and honey in a small saucepan over medium heat. Simmer, stirring occasionally, until reduced by half and syrupy, about 6 to 8 minutes.
06 - Transfer Brussels sprouts to a serving platter, drizzle with balsamic glaze, and serve immediately.
