Preheat Oven to 400. Cut the ends off of all the Brussel Sprouts and then cut them in half from top to bottom.

In a large skillet heat the olive oil. Place the Brussel Sprouts in the pan with the halved side down. Add the garlic and sprinkle with salt and pepper. Let the Brussel Sprouts cook undisturbed until the halved side turns brown.

Transfer the Brussels Sprouts and garlic in a baking dish and place in the oven for 10-20 minutes until tender. Add the balsamic vinegar and toss.
