Preheat oven to 400°F (use a toaster oven to save energy).

Remove excess papery outer layers of garlic bulb, still leaving a thin layer of skin on the cloves. Using a sharp knife, lay the bulb on its side and cut the tips off each clove, exposing them.

Place the garlic bulb on a small piece of aluminum foil. Drizzle olive oil on top, spreading the oil with your fingers to touch each clove. Wrap the bulb loosely in the aluminum foil.

Place in preheated oven for 45 minutes, or until the cloves are golden brown and soft. 

Remove from the oven and let cool before using your fingers to squeeze each clove out of the skin.
