Cut loaf in half lengthwise and set aside on rimmed baking sheet.
Mince garlic, add to small saucepan with butter and salt. Melt over very low heat.
When butter is completely melted, turn off flame and allow to rest for 10 minutes.
Brush melted butter over bread. Use all of the butter, but only about half of the garlic.
Bake at 400° for 5-7 minutes. Once bread is warm throughout, turn oven to broil setting and broil until golden brown, rotating pan midway to ensure even browning.
Slice and serve immediately.
