You can never have enough garlic, especially when it comes to a garlic bread.
Crank the oven to 425° and line a big baking sheet with foil.
Make the garlic butter for the bread: In a small bowl, mix softened butter with garlic, salt, and parsley until well combined.
Spread cut sides of bread liberally with the garlic butter and sprinkle them with Parmesan.
Bake in the prepped oven until the bread is toasty and golden at the edges, about 10 minutes.
