Start by roasting your garlic. Preheat your oven to 350 degrees and remove your butter from the fridge to soften.
Slice the top of your bulb of garlic to expose the cloves. Place them in a square of tin foil, and drizzle with the olive oil. Lightly sprinkle with salt and pepper. Crimp together the foil to form a seal with plenty of air inside to circulate.
1 bulb garlic, 1/2 teaspoon olive oil
Place in the oven and roast at 350 degrees for 25 minutes. While the garlic is roasting, chop your parsley.
When the garlic has roasted, remove from the oven and carefully open the tin foil. Let it cool until you are comfortable handling it. Place the butter into a bowl, and squeeze out the cloves of garlic onto the butter. Add the parsley and salt. Use a spatula or fork to stir the mixture together until it is evenly combined.
12 tablespoons butter, 3 tablespoons fresh parsley, 1 teaspoon salt
Slice your loaf of bread in half lengthwise so you have two long boat shapes. Use the spatula to smear half the butter mixture on each piece of bread. Grate the Parmesan cheese over the butter mixture.
1 loaf fresh French bread, 1/4 cup Parmesan cheese
Gently wrap the bread in foil, with the two coated halves of bread facing each other. Place in your still preheated oven and bake for 10 minutes. Remove the bread and turn the oven to broil. Open the two halves of bread so that the garlic butter is on top and return it to the oven for three to four minutes, until the cheese has melted a bit and the bread has browned to your liking.
In making my garlic bread, I make two long boat shapes and bake them that way, cutting slices to eat after the bread has cooked but you can make slices down the loaf without cutting through in any spot and spread the garlic butter on each slice and bake it that way and slice it later.
