Using a sharp knife, cut the loaf of bread into an inch-thick slice.
In a bowl, add butter, garlic powder, and salt. Mix well using a fork or a spatula so that everything is well incorporated.
Using a butter knife, spread the garlic butter mixture evenly across the sides of each bread piece.
Place the bread slices on an aluminum-lined baking tray.
Place the baking tray in the oven at 350-degree F for about 8 to 10 minutes.
Flip halfway into the cook and bake until you get a crispy golden crust.
Once done, take the baking tray out of the oven, garnish the bread slices with freshly chopped parsley and serve.
