Preheat oven to 190°F.
Add all the ingredients into a small baking dish. Make sure all the ingredients are submerged in the olive oil. I used a 9"L x 7"W oval baking dish
Roast the garlic for 1.5 to 2 hours. Check on the garlic at about the 1.5 hour mark with a toothpick. If the garlic is golden and the toothpick goes into the garlic easily, then it's done.
Cool the garlic confit at an area away from the stove so that it cools off quicker. Once completely cooled, transfer the garlic to a sterile pickling jar and store in the refrigerator immediately. The garlic confit can be stored in the fridge for up to 3 weeks.
