Making focaccia takes time and rushing it will not yield the best results. By letting the dough rest overnight it will be more likely to be chewier and more like a traditional focaccia loaf. If you can’t wait until the next day to continue to make the bread, follow the instructions up until the second rise and then instead of placing the dough into the fridge, place it back into the bowl, cover and let it rise for another hour and a half (third rise) then follow the instructions from that point on.
Store focaccia in a resealable container (not in the fridge), although a Ziplock bag works well too. It will last for about 4-5 days at room temperature.
To freeze, wrap it tightly in plastic wrap and seal it in a Ziplock bag. It’s good in the freezer for up to 3 months. Thaw it on the counter to room temperature before serving. It can also be warmed up in the oven or heated up in a sauté pan. Brush the tops and bottoms of the bread lightly with olive oil, then heat until golden.
