1. Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper for easy cleanup.
2. In a large bowl, combine the Brussels sprouts with olive oil, garlic, salt, and pepper. Toss until the sprouts are well coated.
3. Spread the Brussels sprouts in an even layer on the prepared baking sheet. Ensure they are not overcrowded to allow for even roasting.
4. Roast in the preheated oven for 20-25 minutes, or until the edges are crispy and golden brown. Stir halfway through for even cooking.
5. Remove from the oven and immediately sprinkle with Parmesan cheese. Toss gently to coat the sprouts as the cheese melts.
6. For an optional twist, add lemon zest and balsamic vinegar before serving to enhance the flavors with a fresh and tangy note.

Growing up, I learned from my abuela that cooking is all about using your senses. So, trust your instincts — you’ll know these sprouts are ready when they’re beautifully caramelized and aromatic.
