01 - Preheat the oven to 425°F. Line a baking sheet with parchment paper.
02 - Toss Brussels sprouts in a large bowl with olive oil, kosher salt, and black pepper until evenly coated.
03 - Place Brussels sprouts cut side down in a single layer on the prepared baking sheet.
04 - Roast for 20 to 25 minutes, stirring halfway through, until golden brown and crispy on the edges.
05 - While roasting, combine balsamic vinegar and honey in a small saucepan over medium heat. Simmer for 5 to 7 minutes, stirring occasionally, until the mixture thickens and reduces by half. Remove from heat.
06 - Transfer roasted Brussels sprouts to a serving platter. Drizzle with the balsamic glaze and toss gently to coat. Serve immediately.
