Using a sharp knife, cut off the tops of the garlic (where the paper comes to a point), then peel as much of the paper off as you can without the cloves falling off. Using your fingers in a rubbing motion works well.
Place each head of garlic on a small piece of foil, enough to completely wrap the garlic in.
Drizzle with a teaspoon of olive oil and sprinkle with salt, then wrap the foil around each head and place in an oven safe dish, on a sheet pan, or in individual muffin cups.
Roast the garlic in the oven for about 50 minutes. They will be a nice golden caramel color.
Let them cool for at least half hour, unwrapped, before gently squeezing the garlic out.
Using a fork or the back of a spoon, mash the garlic and spread on toasted bread, stir into mashed potatoes and use mix into veggies or pasta.
