Preheat oven to 250°F (121ºC) and prepare ingredients. *To make this tender, slow-roasted garlic in an hour, see stovetop instructions below.
Using a sharp knife, trim the ends then peel each garlic clove, leaving it intact and discarding any bruised cloves.
Place garlic and oil in a small oven-proof baking dish, adding a little more oil if cloves aren’t submerged, then top with fresh herbs. Bake for 2 hours until cloves are tender and lightly browned in colour.
Remove baking dish from oven and let cool completely. Once cooled, remove cloves from baking dish with a slotted spoon and place into a sterilized canning jar. Pour oil over cloves, seal tightly and refrigerate.
