01 - Preheat the oven to 425°F and line a baking sheet with parchment paper.
02 - In a large bowl, whisk together the olive oil, balsamic vinegar, honey, minced garlic, salt, and black pepper.
03 - Add the halved Brussels sprouts to the bowl and toss thoroughly to ensure they are evenly coated with the mixture.
04 - Spread the sprouts cut-side down on the prepared baking sheet in a single layer.
05 - Roast for 22–25 minutes, stirring once halfway through the cooking time, until the edges are golden and crispy.
06 - Transfer the sprouts to a serving dish, drizzle with any remaining glaze from the pan, and toss gently. Garnish with toasted nuts and Parmesan if desired.
