Preheat the oven to 400°F and line a sheet pan with parchment paper.
In a small dish, combine the soft butter, garlic, garlic powder and the chopped parsley.
On a cutting board, slice the loaf of bread in half horizontally. Spread the garlic butter mixture equally on the cut surface of each bread half.
Place the bread on the sheet pan and transfer it to the oven.
Bake for 8 to 10 minutes or until the butter has melted and the bread begins to turn golden.
Remove the sheet pan from the oven and transfer the bread to the cutting board.
Sprinkle additional chopped parsley on the bread and cut into 2-inch slices. Serve immediately
Notes
If your loaf of bread has a misshapen top and tilts to the side, use wads of aluminum foil as a bolster to keep it flat. If it tilts the butter will roll off as it melts.
For variety add fresh chopped rosemary or thyme to the garlic-butter mixture
Use lots of fresh grated or crushed garlic. The jarred stuff doesn't have as much flavor but works in a pinch.
After the bread has cooked for 8 minutes, you can add Parmesan or Mozzarella cheese then broil until melted.
