Preheat the oven to 350 degrees F.
Put the garlic cloves in the bowl of a food processor and pulse until minced. Add the basil, butter, Parmesan, salt and pepper and process until it becomes a smooth paste, scraping down the sides of the bowl as you go.
Slice the loaf of bread in half lengthwise, being careful not to cut all the way through. Using a rubber spatula, spread the garlic-basil mixture on both halves. Put the bread back together like a sandwich and wrap tightly with foil.
Place the bread on a sheet pan and bake for 15 minutes, then unwrap the bread and continue to bake until browned in spots, about 10 minutes more. Slice crosswise and serve warm.
