The fougasse can be made a day ahead. Wrap in aluminum foil and reheat in the oven just before serving.
Variations
Fougasse can also be cooked on a pizza stone. Flour the dough well and shape it on a pizza peel. Once you’ve transferred it to the pizza stone, quickly reshape it into a fougasse shape. For an olive fougasse, replace the bacon and onion with ⅓ cup (55 g) dried black olives, pitted and coarsely chopped.
