Preheat the oven to 350 degrees F.
Place the garlic on a foil-lined baking sheet and rub 1 teaspoon of oil into the top of each head. Sprinkle lightly with salt and pepper and place, cut side down, on the baking sheet. Bake until the cloves are soft and golden, about 1 hour. Remove from the oven and let sit until cool enough to handle. Squeeze each head of garlic to expel the cloves into a bowl. Mash into a paste. Set aside until needed.
Yield: 1/4 cup
Note: Each head of garlic makes approximately 2 tablespoons of roasted garlic
