Cut top off of garlic, about 1/4 inch deep to expose garlic cloves. Remove any loose paper skins. Don't worry if a few cloves slip out, just place them back where they belong and set aside.
On a sheet of aluminum foil large enough to wrap the garlic in (I use precut 8"x 8" sheets and they work perfectly for this), add the head of garlic to the center cut side face up. (Pro Tip: If you are doing multiple heads of garlic put foil sheets in a muffin tin. This will hold the garlic heads without making a mess when adding the oil).
On garlic clove, drizzle the olive oil and sprinkle with salt and pepper.
Tightly wrap garlic in foil and put in oven for 1 hour, or until the garlic is soft and brown.
Let cool until it is easy to handle (about 10 minutes) and enjoy!
Notes
Roasted Garlic can be stored in the refrigerator for up to 2 weeks if stored in an airtight container completely submerged in good olive oil. You can use the garlic infused oil in salads or with cooking to give your food extra flavor.
