01 - Preheat your oven to 425°F (220°C). Line a standard baking sheet with parchment paper to prevent sticking and simplify cleanup.
02 - In a large mixing bowl, combine the trimmed and halved Brussels sprouts with olive oil, kosher salt, and freshly ground black pepper. Toss thoroughly until all sprouts are uniformly coated.
03 - Distribute the seasoned Brussels sprouts in a single, even layer on the prepared baking sheet. Ensure that the cut sides face downwards; this promotes optimal caramelization.
04 - Roast in the preheated oven for 20 to 25 minutes. Gently stir the sprouts once halfway through the cooking process. Continue roasting until they are golden brown, crisp on the exterior, and tender when pierced.
05 - Immediately after removing the Brussels sprouts from the oven, drizzle them with balsamic vinegar and the optional honey or maple syrup. Toss vigorously to ensure every sprout is evenly coated with the glaze.
06 - Serve the roasted Brussels sprouts hot as a flavorful and versatile side dish.
