Cut a hole in the middle of the loaf and hollow out the bread creating a dish to house the fondue, slice the edges of the loaf leading up to it. Mix together the garlic, olive oil and parsley and brush all over the loaf and into the cut gaps.
Pour in the fondue into the hole of the bread and bake for 20 minutes until the bed is crispy. Tear off chunks of the bread and dunk into the hot fondue.
