You can definitely make focaccia bread ahead of time! Make the dough and let it have its first rise at room temperature. Then, immediately place the dough in the fridge for up to 18 hours. Remove the dough from the fridge and start at step 4 of the recipe. The dough will be cold, which is totally fine! You can also freeze focaccia after it is baked. Slice it up and freeze it in an airtight container or freezer bag for up to 3 months. You can thaw it in the fridge overnight when you are ready to eat it.
