Preheat the oven to 400 degrees. Line a baking sheet with parchment paper. Slice the loaf of bread in half and then again (lengthwise) to get 4 pieces.
Mix together the softened butter, garlic cloves, garlic powder, salt, and italian seasoning in a bowl until smooth and well combined.
Spread the butter mixture evenly over the bread and then top each piece with shredded cheese.
Bake for 10-14 minutes, until the cheese is melted and the edges of the bread are golden brown.
Optional: sprinkle with chopped green onion.
