With a sharp knife make ¼” deep, diagonal score marks on the top of the loaf, about 1 inch apart. Or make one long ¼”slit down the middle of the 9 inch length of the loaf.
Bake for about 25 minutes until golden brown and the pieces of garlic and cheese are just beginning to toast. (Depending on the oven, it may a few minutes less or more than this.)
Adding sautéed garlic to the top is optional if garlic isn’t your thing. Brushing with melted butter or a butter substitute adds flavor and color that is well worthwhile.
