Preheat oven to 400F.
Toss Brussels sprouts and garlic with olive oil, lemon juice, salt, and pepper in a large bowl until evenly coated.

Bake 25-30 minutes, tossing halfway through, until edges are golden brown and centers are tender.
Serve warm with extra lemon juice and top with grated parmesan cheese.
