Heat your oven to 375 degrees F
Carefully cut the top off each head of garlic. You want to expose most of the cloves of garlic. Peel away a bit of the papery outside and place the heads of garlic in a small baking dish. Drizzle each head of garlic with a tsp or so of olive oil. Cover with aluminum foil, bake for around 45 minutes, or until golden and delicious looking!
Remove from the oven, carefully remove the aluminum foil, and let rest till they're cool enough to handle. You can squeeze the cloves of garlic from the bottom up to remove them. Use in a recipe, spread on buttered toast, or store in an airtight container in the fridge for up to a few days.
