Combine all your garlic butter ingredients into a bowl and mix until well combined.
Cut your bread in half lengthwise and spread the garlic butter equally onto each half.
Place the sourdough garlic bread inside the oven for about 4-6 minutes making sure to keep watch for some slight browning to start to occur on the edges of the loaves and on top of the bread.
Remove the bread from the oven and allow to cool for about 5 minutes before topping with flaky sea salt, cutting, and enjoying!
