01 - Preheat your oven to 425°F (220°C). Line a baking sheet with parchment paper for easy cleanup.
02 - In a large bowl, combine the Brussels sprouts, olive oil, minced garlic, salt, and black pepper. Toss thoroughly to ensure all sprouts are evenly coated.
03 - Spread the seasoned Brussels sprouts in a single layer on the prepared baking sheet. Position them cut-side down for optimal caramelization and crisping.
04 - Roast for 20 minutes. Stir the sprouts once halfway through this period to promote even cooking and browning.
05 - Evenly sprinkle the grated Parmesan cheese over the Brussels sprouts. Return the baking sheet to the oven for an additional 3 to 5 minutes, or until the cheese is melted and lightly golden.
06 - Transfer the roasted Brussels sprouts to a serving dish. Garnish with fresh parsley and serve with lemon wedges, if desired.
