Preheat the oven or countertop toaster oven to 500° F/260° C.
Remove the outer papery covering of the garlic, but leave the covering on the individual cloves. Slice off the top of the head so that most of the cloves are exposed.
Place on a piece of aluminum foil. Drizzle the oil over the cloves. Fold the foil over the head to completely enclose it.
Roast for about 30 minutes, until the garlic is completely soft and lightly browned with some slight caramelization. Use a knife to remove the roasted cloves from the head and spread each clove on a slice of bread and drizzle with more extra virgin olive oil.
