While garlic is cooling, slice a loaf of bread down the center to create two flatter sides, like you’re preparing a sub. Place bread halves side by side on a large, rimmed baking sheet. Set aside.
Once roasted garlic heads are safe to touch, trim the edges of the papery skin to make it easier to retrieve the garlic. Retrieve the roasted garlic cloves from the head and add to a medium bowl.
Mash garlic, butter, and salt in the bowl. Stir and mash until well mixed.
Spread the garlic butter over the bread halves, creating an even layer.
Bake for 8-15 minutes, depending on toast level preference (shorter for softer bread, longer for crispier bread). I like to bake mine until deep golden at the edges with a crispy crust, about 12 minutes.
Carefully slice once cool enough to handle. Top with parsley and serve. Optionally, sprinkle with grated parmesan or garlic salt for a special treat.
