Cut the tips of the head of garlic, put it in a pan, cut side up. Drizzle with olive oil, and sprinkle on salt and pepper. I like to put the little tips in the pan, and add a bunch of extra olive oil, to let the garlic infuse the olive oil to use for salad dressing.
Cover the pan with foil, and bake for 45 minutes at 350 degrees. Then, remove the foil and let it bake for 15 more minutes.
