Preheat Oven: Set oven to 400°F (200°C). Line a baking sheet with parchment paper for easy cleanup.
Prepare Brussels Sprouts: Trim the ends, remove any yellow outer leaves, and cut sprouts in half.
Season: Place sprouts in a large bowl. Toss with olive oil, garlic (if using), salt, and pepper until evenly coated.
Roast: Spread them cut side down in a single layer on the baking sheet. Roast for 20–25 minutes, stirring halfway through, until golden brown and crispy on the edges.
Finish: Drizzle with balsamic vinegar or a squeeze of lemon juice before serving, if desired.
