Preheat oven to 425 degrees.
Trim the end of the brussel sprouts but keep them in tact.
Cut the brussel sprouts in half. If you happen to have some tiny brussel sprouts in the group, keep them whole.
Put the prepared brussel sprouts on a large baking sheet. Toss them with the oil, garlic and salt & pepper.
For good caramelization, put the cut brussel sprouts cut side down.
Put in the oven and bake for 20-25 minutes. Toss the brussel sprouts half way through.
Remove from oven once the brussel sprouts are tender and caramelized.
