02 - Cut the baguette in half lengthwise, then slice each half into 2 to 3 pieces depending on size.
03 - Combine the softened butter, minced garlic, chopped parsley, salt, and black pepper in a bowl, mixing thoroughly.
04 - Evenly spread the garlic butter on the cut sides of the bread. Optionally, sprinkle with grated Parmesan cheese and chili flakes.
05 - Place the bread pieces buttered side up on the prepared baking sheet.
