Preheat the oven to 375 degrees. Line a baking dish with tin foil for easier clean-up.
Combine the butter, garlic, Parmesan cheese, parsley, and sea salt, and freshly cracked pepper, to taste together in a bowl; mix until evenly combined.
Slice the loaf of bread lengthwise in half. Equally spread the butter mixture over each half of the loaf. Place the bread onto the baking sheet then loosely cover the top of the bread with a piece of tin foil.
Bake for 15 minutes; remove the tin foil and turn the oven to broil. Cook the bread, watching VERY carefully, so it doesn't burn. Remove from the oven, slice, and serve immediately. Enjoy!
