Cut the loaf into slices, not cutting through to the end.
Peel the garlic, grate the cheese on a track, finely chop the parsley.
Combine grated cheese, grated garlic, butter and parsley. Season with salt to taste. Place filling through each slice and wrap the whole loaf in foil.
Bake in an oven preheated to 180 degrees C for 15-20 minutes, open the foil and bake for another 3-5 minutes. Put the finished baked loaf on a dish and serve.
