*20 ounces was about 22 slices of the butter bread I used.
**While it’s best if you do refrigerate overnight, you don’t have to. If you’re in a hurry, don’t have time to plan ahead, and need to make it a quick and easy French toast casserole for a crowd, that’s ok. But let me just say, that the flavors will be at their best after chilling for at least a few hours.
How do you store leftover French toast casserole?
You can either cover it in plastic wrap or transfer your cinnamon bread casserole into an airtight container before storing it in the refrigerator for up to 5 days. When you’re ready to serve, just reheat it in a 350ºF oven or in the microwave on high ’til heated through.
