Heat oven: Preheat the oven to 400ºF.
Prep baking sheet and bread: Line a large baking sheet with parchment paper or aluminum foil.
Cut the bread: Slice the loaf into two equal halves, creating two pieces that are each 12 inches long. Next, carefully slice each piece open lengthwise (you'll end up with 4 pieces). Place the bread on the prepped baking sheet cut sides facing up.
Make the garlic butter: In a small bowl, combine the softened butter, olive oil, minced garlic, chopped parsley, and salt. Stir until the mixture is smooth, allowing for a few small lumps of butter.
Spread on the garlic butter: Use a spatula to evenly spread the garlic butter mixture over the top of the bread, coating all the way to the edges of the bread.
Bake garlic bread: Place the baking sheet with the bread in the oven and bake for 10-15 minutes, until the edges turn a delightful golden brown and become crispy. If you prefer a softer garlic bread, reduce the baking time, and if you prefer a crispier texture, extend the baking time accordingly.
Slice bread: Once done, carefully slice the bread into 2-inch sections and serve it piping hot. Enjoy!
