Preheat oven to 325 degrees F. Remove any of the loose, paper-like skin and lightly baste bulbs of garlic with olive oil. Wrap in foil and poke a few holes to allow steam to escape. Bake for 1-1/4 hours. Cut garlic in half horizontally. To serve, warm Brie in 325 degree F oven until just starting to melt. Spread cheese on bread slices and then spread warm garlic pulp on top.
