9-10 medium garlic cloves, unpeeled
6 tbsp. unsalted butter, softened
2 tbsp. grated parmesan cheese
½ tsp. table salt
1 loaf high quality Italian bread (preferably football shaped), halved horizontally
Ground black pepper
Adjust oven rack to the middle position and hear the oven to 500 degrees. Meanwhile, toast the unpeeled garlic cloves in a small skillet over medium heat, shaking the pan occasionally, until fragrant and the color of the cloves deepens slightly, about 8 minutes. When cool enough to handle, peel and mince the cloves (you should have about 3 tbsp.). Using a dinner fork, mash the garlic, butter, cheese, and salt in a small bowl until thoroughly combined.
Spread the cut sides of the loaf evenly with the butter mixture; season with pepper to taste. Transfer the loaf halves, buttered side up, onto a rimmed baking sheet; bake until the surface of the bread is golden brown and toasted, 5 to 10 minutes. Cut in slices and serve immediately.
