Set your oven to 350 degrees. Cut off the top of the garlic bulb, exposing the tip of each individual clove. Peel away any excess skin, and place the garlic on a sheet of aluminum foil. Drizzle with olive oil and wrap the bulb with the foil, twisting the excess aluminum foil together at the top. Put in the oven on a baking sheet and allow it to cook for 20-30 minutes. Let the garlic cool slightly before opening, as hot steam and oil may escape when it is fresh out of the oven.
Use as a topping for meats, mix into roasted squash or potatoes, or substitute for dishes that call for raw garlic.
