Leftovers can be stored in a closed container in the fridge for 2 days or in the freezer for up to 1 month. I find the cobbler tends to get too soggy after 2 days in the fridge as the dough will absorb more moisture from the fruit. For this reason, I actually always store my leftovers in the freezer and reheat for about 60-90 seconds in the microwave before eating.
