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, black pepper, and garlic powder until evenly coated.
03 - Spread the 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 they are golden and crisp-tender.
05 - While roasting, combine balsamic vinegar and honey or maple syrup in a small saucepan over medium heat. Bring to a simmer, then reduce heat and cook for 5 to 7 minutes, stirring occasionally, until thickened and reduced by half. Remove from heat and let cool slightly.
06 - Transfer the roasted Brussels sprouts to a serving platter, drizzle with balsamic glaze, and serve immediately.
