• Preheat oven to 400°F.
• Trim the top 1/4 inch off of garlic bulbs to expose the cloves, and pull off some of the outer skin.
• Place the garlic on a sheet of aluminum foil. Drizzle each garlic clove with a little olive oil, and add salt and pepper to taste.
• Place a sprig of thyme on garlic, then wrap the foil tightly around the bulbs.
• Roast for 40 minutes or until cloves are browned and soft.

To serve:

• Allow garlic to cool so you don't burn yourself. Discard thyme sprig.
• Press on the outside of garlic to push cloves out of the skin and into a bowl. If you get any skin in the roasted garlic, just pick it out.
• Mash garlic cloves into a smooth paste with a fork.
