01 - Preheat oven to 425°F. Line a rimmed baking sheet with parchment paper.
02 - In a large mixing bowl, combine the Brussels sprouts with olive oil, balsamic vinegar, honey, salt, and pepper. Toss thoroughly until every sprout is evenly coated.
03 - Spread the seasoned Brussels sprouts cut side down on the prepared baking sheet in a single, even layer to ensure proper caramelization.
04 - Roast for 20 to 25 minutes, tossing once halfway through, until the sprouts are deeply golden and caramelized on the edges.
05 - Transfer to a serving dish and sprinkle with toasted nuts or Parmesan cheese if desired. Serve immediately while warm.
