Preheat oven to 400°F. Slice the top off the garlic head to expose cloves. Drizzle with 1 tablespoon olive oil, wrap in foil, and roast for 40-45 minutes until golden and soft.
In a medium bowl, combine softened butter, minced fresh garlic, chopped parsley, parmesan cheese, garlic powder, salt, pepper, and Italian seasoning.
Once roasted garlic cools, squeeze cloves from skins and mash into the butter mixture until well combined.
Spread garlic butter generously over both cut sides of the bread. Place halves back together and wrap tightly in foil.
Bake wrapped bread for 10 minutes. Unwrap, separate halves, and place cut-side up on baking sheet.
Bake uncovered for 5-7 minutes until golden and crispy. Slice and serve warm.
