Slice bread, but not all the way through, leaving slices attached at the bottom.
In a small bowl, cream butter. Add the Parmesan cheese, parsley, paprika, and garlic; mix well. Spread between slices.
Wrap loaf in a large piece of heavy-duty foil (about 28 in. x 18 in.)( I just used regular foil). Bake at 325° for 15-20 minutes or until heated through. 8-10 servings.
