Prepare a large baking sheet by lining it with parchment or foil
In a small bowl, combine cheeses together, set aside
Stir softened butter, minced garlic, parsley, salt, and pepper together to combine, then, spread evenly over one side of each slice of bread and reassemble the loaf over a large piece of aluminum foil
Sprinkle cheese mixture between bread slices and wrap up sides and top with foil
Place on a baking sheet and bake for 20-30 minutes, then, open up the foil and bake for an additional 5 minutes until the cheese browns and the bread toasts up
