Heat your oven to 400℉.
Peel the outer papery skin off the outside of the head of the garlic, being careful to keep the garlic cloves attached to the base.
1 head garlic
Slice the top off the head of garlic, exposing the tops of each clove. Drizzle the garlic with the olive oil and sprinkle the salt on top.
1 tablespoon olive oil, ½ teaspoon salt
Wrap the garlic head in aluminum foil and roast base-side down in the oven for 40 to 50 minutes until the cloves are extremely soft when poked with a knife or toothpick. Let cool slightly.
Add the roasted garlic, softened butter, Parmesan cheese, and optional honey and mash together until smooth.
1 stick (½ cup, 4 ounces, or 113grams) butter, ¼ cup Parmesan, 1 tablespoon honey
Add additional salt and optional pepper to taste.
¼ teaspoon ground black pepper
