Yummy, crusty, cheesy goodness from America's Test Kitchen. Garlicky, but not overpowering. Using a small cheese grater or zester to grate the garlic cloves will give a better texture. Better than store-bought!
Preheat oven to 400 degrees. Move rack to the 2nd from bottom space.
Saute garlic, 1 tablespoon butter, and water over low heat, 7 to 10 minutes. It forms a paste.
Combine hot garlic, 7 tablespoons butter, salt, and pepper in a bowl and spread on both halves of the bread. Put the halves back together and wrap in foil. Place on baking sheet and bake for 15 minutes.
Unwrap bread and place halves, buttered sides up, on baking sheet. Bake until it begins to color, about 10 minutes. Take out of oven and turn on the broiler.
Sprinkle bread with cheese. Place under the broiler until cheese has melted and bread is crispy, about 1 or 2 minutes. Put on cutting board, cheesy side down. Cut into pieces. Serve.
