Heat oven to 375°F.
Cut the garlic head a thirds of the way down from the top to expose the cloves. Drizzle the open end of the garlic with some EVOO and wrap in aluminum foil and place in oven for 45-60 minutes. Once the garlic is roasted, remove from the oven to cool. When it's cool enough to handle, you can either squeeze the garlic out of remove each individual clove.
In a medium-sized mixing bowl, mash the garlic cloves until a paste is formed. Add in the remaining ingredients and mix together until combined. Serve with some cheesy bread, homemade or store-bought, and dip away! For a variation, spread this on focaccia and pop it in the oven until the cheese melts. Yum-O!
