Place a large stainless steel pan in the oven and preheat the oven to 325F.
Cut the thick ends off of the brussels sprouts, then slice them in half.
Place them in a bowl with the minced garlic.
Drizzle the olive oil over the sprouts and add the salt and pepper.
Toss the sprouts to coat them with the olive oil and garlic.
When the oven is heated, pour the brussels sprouts into the pan and return the pan to the oven.
Roast the sprouts for about 30 minutes, stirring two or three times.
Serve.
