Preheat your oven to 400 degrees F (200 degrees C).

Cut the head of garlic in half width-wise, then place both halves on a sheet of aluminum foil big enough to wrap around the garlic.

Drizzle the olive oil over the cut sides of the garlic halves and on top of the skin, then replace the top half onto the bottom half and wrap the aluminum around the garlic to cover it completely.

Place on a baking sheet or a baking dish and put the garlic into the preheated oven. Roast your garlic for at least one hour.

Take the baking sheet out of the oven and open the foil, let your roasted garlic cool for 2-5 minutes, then squeeze out the cloves and use as needed.

Keep in fridge for up to two weeks in an air tight container
