Totally! You can prep the batter ahead of time and store it in the fridge up to a day in advance. You can also cook and cool the French toast, then freeze it for 30 minutes in a single layer on a baking sheet. Once it's frozen, transfer the slices to a ziplock bag and freeze for up to 3 months. To serve, bake at 350ºF for 10 minutes or until heated through or reheat in the toaster!
