Store leftover bread in an airtight container in the fridge for 2-3 days. To reheat, pop bread into a 350°F oven for 5-10 minutes until it is crisp and warmed through. You can also pop individual slices right from the fridge into a toaster or toaster oven. (You might remember we usually don't recommend storing bread in the fridge, but we make an exception for this loaf: it needs to stay cold since it's packed with cheese!)
