Preheat your oven to 375°F (190°C).
Cut the loaf of bread in half lengthwise.
In a bowl, mix the softened butter, minced garlic, parsley, salt, and pepper until well combined.
Spread the garlic butter mixture evenly over the cut sides of the bread.
Place the bread halves on a baking sheet, cut side up.
Optional: Sprinkle red pepper flakes on top for a spicy kick.
Bake in the preheated oven for 10-12 minutes, or until golden brown.
For extra crispiness, broil for an additional 1-2 minutes (watch closely).
Remove from the oven and let cool for a minute.
Slice and serve warm.
