01 - Preheat your oven to 425°F. Line a baking sheet with parchment paper for easy cleanup.
02 - In a large mixing bowl, combine the trimmed and halved Brussels sprouts with olive oil, kosher salt, freshly ground black pepper, and garlic powder (if using), tossing thoroughly until all sprouts are evenly coated.
03 - Spread the seasoned Brussels sprouts in a single, even layer on the prepared baking sheet. For optimal caramelization, ensure the cut sides are facing down.
04 - Roast for 20 to 25 minutes, stirring the Brussels sprouts halfway through the cooking process, until they are tender-crisp and deeply golden-brown.
05 - Remove the roasted Brussels sprouts from the oven. While still hot, drizzle generously with honey and apple cider vinegar (or balsamic vinegar), then toss thoroughly to ensure an even coating.
06 - Serve immediately as a delightful side dish. Garnish with additional freshly ground black pepper if desired.
